NextGen Geoscience Professionals: What is important for their career development

Educating the next generation of geoscientists is a constant discussion in many forums around Australia. However, formal education as part of a degree program is only a partial aspect of career development. Education generally happens under an instructor's guidance and may involve both theory and practice often within a school or university. Whereas training is usually more focused on practical skills and can be provided either in an educational setting or on the job. Mentoring also provides a significant role in career development and is also seen as crucial for bridging generational differences in the workplace.

This talk is going to focus on the importance of community, mentorship, and career development. Or more specifically, the importance of mentorship and how that builds a strong sense of community. To support this vision, we will have some early career geoscience professionals from a range of backgrounds provide insights into why they started careers in the industry and give their feedback on the community as it is now, how they would like to see it in the future, and some of their thoughts on how to reach that goal.

As a special highlight of the evening, we will be presenting the Lindsay Ingall Memorial Award to the family of the late Bob White in recognition of his outstanding contributions to the field of exploration geophysics.



NSW Tech night: Advanced geomodelling to reveal buried deposits

Wednesday, April 24, 2024

Title: Advanced geomodelling to reveal buried deposits

Presenter: Addison Tu

Date and time: Wednesday, 24th April 2024 at 1800 (NSW)



Porphyry deposits are of important societal significance as critical sources of copper. 

Copper demands are projected to increase significantly to supply the transition to net-zero, but discoveries have dwindled in recent decades. The finite number of deposits exposed at the surface are nearing depletion, and advancements to exploration techniques must target buried deposits. Here we present a workflow which incorporates machine learning predictions for deposit formation within the crust, with a highly calibrated landscape evolution model to track the vertical motion of deposits through geological time. The results inform where deposits may be preserved and at what depth, or where deposits have been destroyed by erosion. We tested this approach on the mountains of New Guinea, which feature abundant volcanism responsible for deposit formation at depth and extreme erosion to exhume deposits toward the surface. Our approach identified high prospectivity in accordance with the spatial extents of known surface deposits, identified several highly prospective regions for near-surface deposits and where deposits have been destroyed by erosion. Our workflow provides a region-scale prospecting tool to de-risk the economic and environmental cost of field-based exploration. Importantly, the workflow is open-source, scalable to other regions and even adaptable to other mineral systems (with constraints on the depth of formation


Addison is a PhD student and Research Assistant within the Earthbyte group, working closely with Dr. Sabin Zahirovic and Dr. Tristan Salles. His research focuses on Eastern Australia, particularly concerning the eastward accretion of microcontinents and volcanic arc-islands since the Cambrian. Geological events in this region and period involve the formation of mountains and the closing of seaways, with many implications for climate, past landscapes and environments, and the formation and preservation of economic deposits.

Addison utilises landscape evolution modelling, tectonic models, and thermochronology with a focus on linking Earth’s surface processes and evolution to other Earth Systems such as the tectonics, climate and the ocean. He also has experience developing landscape evolution models and landform design tools within industry.


NSW Tech talk: Continental fragment collision in subduction and the dramatic uplift acceleration in the Eastern Anatolian region

Wednesday, October 18, 2023

Title: Continental fragment collision in subduction and the dramatic uplift acceleration in the Eastern Ana-tolian region

Presenter: Peigen Luo

Date and time: 1800 (Sydney) Oct 18, 2023

Registration: here


The interaction of the subducting lithosphere and embedded continental fragment is a characteristic feature in many subduction zones with complexity. We conducted dynamic subduction modelling to investigate the interactions between the subducting lithosphere and an embedded continental fragment in the Cyprus subduction zone. This study aims to elucidate the effects of the continental fragment on various aspects, including the evolution of regional uplift in the subduction back-arc, morphology of the subducting slab, and internal deformation in the central Anatolian back-arc region during the process of continental fragment indentation. The geodynamic models provide explanations for local seismic data that indicate the absence of lithosphere on the subducting slab ahead of the continental fragment and the puzzling acceleration of uplift in the Central Taurides region over the past 450,000 years. The models demonstrate that the removal of the detached slab due to slab tearing alters the surface deformation and mantle upwelling in the Central Taurides region by reducing the shortening deformation during the collision with the continental fragment. This shift in deformation results in a significant increase in the uplift rate during the subduction slab breakoff process in this region from 450,000 years ago to the present.


Peigen Luo is a dedicated researcher in the field of geological processes. After recently completing his PhD thesis, he's spent years studying plate tectonics, subduction modelling, and applying high-performance supercomputing to geological challenges. Starting his academic journey in 2020 as a PhD student, Peigen has consistently aimed to deepen his understanding and share insights with the academic community. He has also collaborated with the University of New South Wales (UNSW) in a casual professional capacity since 2023. Passionate about both geology and computational science, Peigen seeks to continuously learn and contribute to the ever-evolving field of geoscience.

ASEG NSW - “Geophysics in the Park”: How can Industry support geophysics education?

Wednesday, September 20, 2023

Title: “Geophysics in the Park”: How can Industry support geophysics education? with presenter Dr James Daniell 

Date and time: Wednesday 20th September at 1800 AEST



On Wednesday 20th September, ASEG NSW brings a presentation on Mergers, cutbacks, and closures of geoscience departments in Australia have been well documented in the media. Outreach events supported by industry and intended for university students and young professionals can provide an opportunity for ongoing education, gaining practical experience, and networking opportunities with industry professionals. In August this year, Fender Geophysics hosted its second outreach event to demonstrate basic geophysical surveying techniques. ‘Geophysics in the Park’ was attended by 14 students, 2 industry professionals, 1 academic, and 1 work experience student. Attendees were shown how to deploy, acquire, and process electrical resistivity imaging and seismic refraction datasets.
Data was acquired in Tunks Park in Cremorne (north Sydney). Tunks Park was chosen primarily as it was known to be a site with ‘thick alluvium’ and likely more interesting than most of the other local parks that were assumed to have Hawkesbury Sandstone located in the shallow subsurface. Tunks Park turned out to be an interesting choice as the existing park was actually constructed as part of land reclamation project in the 1940’s. Historical aerial photos showed the presence of an estuarine mudflats and creek, and it was this creek that was targeted by the geophysical surveying. Unsurprisingly, the creek was imaged as a highly conductive feature within the resistivity data. The refraction data differentiated a boundary between some upper ‘landfill’ and lower sediments but didn’t not image the top of bedrock. 
Despite the geophysical data providing results that were to be expected, Geophysics in the Park provided an opportunity to demonstrate some basic geophysical techniques in an area with an interesting geological history. Students benefitted from gaining some hands-on experience and participated in data acquisition and processing. There is an unmet need for education, training and demonstrations of basic geophysical techniques that can easily be filled by industry. Demonstrations of geophysical techniques do not necessarily require remote field sites. Local parks and sports ovals can be interesting targets for geophysical surveys to demonstrate the various survey techniques. As well as changes in geology and soil, buried debris, services and structures may also be suitable survey targets.
James has spent most of his career undertaking marine geophysical research for James Cook University (2012-2020) and Geoscience Australia (2001-2012). His expertise includes oceanography, geomorphology, sedimentology, geophysics, remote sensing and GIS. However, his research has been focused on mapping the seabed using acoustics and seismic reflection to understand geological processes, oceanography, and the distribution of benthic habitats in both deep and shallow water environments. Geographically his research has focussed on Torres Strait the Great Barrier Reef, however, he has also published research from the Gulf of Papua, Northwest Shelf, Gulf of Carpentaria, and the Tasman Sea. He initially studied palaeontology for a BSc at Macquarie University and followed that up with a Masters in Geology and Geophysics. He completed his PhD through the University of Sydney in 2011.
He returned to Sydney in 2020 and is now a senior geophysicist for Fender Geophysics. He is working at developing a ‘near surface’ geophysics division at Fender which will focus on environmental, groundwater and infrastructure related project. He maintains some ongoing research at JCU and enjoys not marking any more exams.

SEG Distinguished Instructor Short Course (DISC) - Distributed acoustic sensing for seismic measurements – what geophysicists and engineers need to know

Tuesday, September 12, 2023

We are delighted to share with you the details for an upcoming SEG Distinguished Instructor Short Course (DISC) being hosted by the ASEG. 

This course will be run virtually over two days. 


Who: Dr Mark E Willis, Chief Scientific Advisor of Borehole Seismics at Halliburton

When: September 12th and 13th 2023, 9am - 1pm ACST each day. 

Cost: $250 USD for SEG and ASEG members which includes access to software and a copy of the accompanying e-book. ASEG members need to use the code emailed to them, or contact Registration cost for non-members is $375 USD.

Register: Please register here by September 12th.


Course description: Geoscientists and engineers are very comfortable using seismic data sets acquired with geophones, hydrophones, and accelerometers because we have a long, well-defined set of standards for acquiring, processing, and interpreting them. However, distributed acoustic sensing (DAS) seismic measurements are rapidly augmenting, and in some cases replacing, the data from these conventional tools. Technologists are frequently unaccustomed to using DAS seismic data sets since it directly acquires relative strain or strain rate measurements and not the more familiar pressure, displacement, velocity, and acceleration data. There are also acquisition parameter selections that must be made to optimize the acquired data to accomplish the purpose of the seismic survey. This course is designed to build an intuition and understanding of the value, limitations, and applications of DAS seismic technology. In addition to the lecture and accompanying book, software will be provided, which will allow the student to interactively explore DAS seismic technology.

NSW talk: The Seven Deadly Sins Of Scale: Why Petrophysics + Structure + Mineralogy Can Solve The Scale Paradox.

Wednesday, August 16, 2023

Title: The Seven Deadly Sins Of Scale: Why Petrophysics + Structure + Mineralogy Can Solve The Scale Paradox.

Presenter: Jim Austin

Date & Time: Wednesday, 16th August 2023 at 1800



Prior to the last decade, Petrophysicists typically had access to contextual information on the geology, but that information was qualitative, and unreliable.  of non-contextual (cf. geochemistry, maths, statistics). The advent of quantitative methods for mapping mineralogy and rock texture on palaeomagnetic samples took petrophysics out of the dark ages. It provided quantitative geological information on mineralogy and rock texture, which in turn provide insights into a range of contextual constraints, including alteration, deformation and metamorphism. Quantitative mineralogy allows us to classify our petrophysical data accurately, this providing a framework to interrogate data meaningfully. Inversely, petrophysics provides a lens through which to convert mineralogy into physical properties, many of which (unlike mineralogy and geochemistry) are truly scalar. If we can convert mineralogy to physics, we can understand crustal architecture across scales. Whilst petrophysics is gradually becoming more widely used, physics can be complex, magnetic and conductivity in particular. In this talk, Jim will outline the Integrated Petrophysics approach, illustrate how to integrate and use the data, citing case histories on IOCG, Magnetite and Magmatic Nickel deposits across Australia. We’ll discuss seven of the most common traps which lead to misinterpretation.  


Jim Austin occupies the core of a Venn diagram in which petrophysics, geophysics, structural geology, alteration and magmatic mineralogy, GIS and guitar overlap. He is focussed on dissecting the petrophysical and structural anatomy of ore deposits, to understand the interaction of structural controls on alteration.

Unveiling New Horizons Of The Cosmos With The James Webb Space Telescope

Wednesday, April 19, 2023

Title: Unveiling New Horizons Of The Cosmos With The James Webb Space Telescope

Speaker: Jaime A. Alvarado-Montes

Date & Time: Apr 19, 2023 at 1800



The James Webb Space Telescope (JWST) marks the dawn of a new era in astronomy. Not only is JWST important regarding its technological advances applied to the forefront of science, but also because it portends many other significant achievements. Among the most complex and expensive science instruments ever constructed, JWST can potentially be a preeminent tool that will deepen human knowledge about the cosmos and its contents. JWST was put in orbit at the second Lagrange point, a special place around the Sun where the telescope is out of the Earth's shadow and its solar shield will block out the heat from the Sun, Earth, and Moon. This is a unique advantage that maintains JWST at exceptionally low temperatures, enabling observations in the infrared previously unattainable by other instruments such as the Hubble Space Telescope. Such a thermally stable position, combined with the cutting-edge instruments on board JWST, grants us unprecedented access to the most remote corners of the Universe. This will facilitate an understanding of its origin, the formation and evolution of ancient galaxies, the properties of extrasolar planets, and ultimately the formation of the Solar System and the evolution of life as we know it. In this talk, I will discuss the significance of JWST and its long and intricate path to orbit. Also, I will showcase some of the most important findings made by JWST to date and how this instrument is revolutionizing our capacity to do far-reaching astronomy.


My name is Jaime Andrés Alvarado Montes and I’m a professional astronomer originally from Colombia. Currently, I’m a PhD candidate at Macquarie University and I’m passionate about computing techniques, software skills, writing, and learning about science and its constant evolution. My research field are the planetary sciences, with an emphasis on extrasolar planets, moons, rings, asteroids, and comets. Most of my work is about how extrasolar systems evolve: the study of such systems can give us valuable information about their formation and can subsequently help us understand more about the history of our own Solar System. At the moment I'm in the last three months of my PhD and I’m planning on continuing my career in academia as a postdoctoral research fellow, because my ultimate goal is to become a full-time researcher and professor.

The first phase (ChEESE-1P) ran from 2018-2022 and addressed scientific and technical computational challenges in moving existing systems to Exascale in seismology, tsunami science, volcanology, and magnetohydrodynamics. ChEESE-1P initiated the optimisation of 10 Community flagship European codes for the European pre-Exascale and Exascale supercomputers and developed 12 Pilot Demonstrators (PD) that enabled services oriented to critical aspects of geohazards, including hazard assessment, urgent computing, and early warning forecasting.

Following the success of ChEESE-1P, a second 4-year phase (ChEESE-2P) with funding of € 7.8 million was launched in January 2023. Arnau will lead a team of Earth and Computer Scientists across multiple programs that will further develop the ChEESE-1P codes and new codes in geodynamics and glaciology.

We are delighted to be hosting Arnau and welcome you to join us in what will surely be a great seminar.

Exploring the structure, composition and resources of the New Caledonia peridotite ophiolite (SW Pacific): Contributions of geophysics and land-to-sea drilling

Monday, February 13, 2023

Title: Exploring the structure, composition and resources of the New Caledonia peridotite ophiolite (SW Pacific): Contributions of geophysics and land-to-sea drilling

Presenter: Marguerite Godard

Date: Monday 13th February 2023

Time: 6:00 pm to 7:00 pm AEDT



The New Caledonia (NC) ophiolite extends over more than 900 km at the northeastern limits of the Zealandia submerged continent, along the Australia – Pacific convergent plate boundary. It comprises large peridotite massifs forming the Island of Grande Terre (GT) and its recently discovered off-shore extension to the south. The subaerial NC ophiolite is of strategic importance for mineral resources (mainly Ni, Cr and Co from peridotites). Several subaerial and submarine alkaline, and H2-rich hydrothermal vents are observed along the NC ophiolite, the most famous being the Prony Bay Hydrothermal Field. The New Caledonia Ophiolite Land-to-Sea Drilling Project (NCDP), submitted to the International Continental Scientific Program (ICDP) and the International Ocean Discovery Program (IODP), aims at (1) sampling the peridotites and associated lithologies on-land, in coastal waters, and the deep oceanic sub-seafloor, and (2) developing borehole observatories to measure in situ the hydrogeological and (bio-)geochemical processes controlling serpentinization driven hydrothermal systems from continental to marine environments. NCDP will provide a unique sampling to quantify interplays between serpentinization, H2 production, CO2 mineralization and ore mobilization over the different stages of obduction.


Dr. Marguerite Godard is Senior Researcher at the French National Centre for Scientific Research. She is a geochemist, specialist of the study of magma- and fluid-peridotite interactions in the oceanic and ophiolitic lithosphere; she (co-)authored more than 100 publications in international scientific reviews and books. She coordinated and participated to several European and French academic and industrial projects on serpentinization and carbon trapping in peridotite basements and their impact on resources, environment and life (e.g., TotalEnergies 2017-2021; ANR LISZT 2018-2023). M. Godard is one of the main PIs of the New Caledonia Ophiolite Land-to-Sea Drilling Project.
