The tectonic and volcanic history of Northern Zealandia

Title: The tectonic and volcanic history of Northern Zealandia

Presenter: Maria Seton, Associate Professor and Associate Head of Research in the School of Geosciences, University of Sydney

Date and time: Wednesday, 17th July 2024 at 1800



A defining characteristic of the southwest Pacific is the significant amount of continental crust and volcanism distributed throughout the region. This includes the world’s largest submerged continent, Zealandia, which separated from eastern Australia and Antarctica in the Cretaceous during the final phase of Gondwana break-up. A large knowledge gap in the tectonic and volcanic history of Zealandia has been the location and continuity of the Mesozoic subduction related magmatic arc and the Late Cretaceous to Eocene rift-related volcanics. In addition, widely distributed, intraplate Cenozoic volcanism, which appears to pockmark much of Zealandia, has been difficult to explain via existing models. To address these gaps in our understanding, we conducted several research voyages on the RV Investigator and its precursor, the RV Southern Surveyor. We undertook a series of dredges, informed by seismic reflection profiles, to target places where basement outcrops at the seabed. We performed detailed geochronological and geochemical analysis of these samples and combined this with regional geophysical data interpretation to determine the location and orientation of the Mesozoic Gondwana magmatic arc axis (Median Batholith) from New Zealand through to the northern reaches of Zealandia. We further mapped the extent of Late Cretaceous to Eocene rift-related volcanics and their relationship to strong positive magnetic anomaly signatures in the region as well refining the age and extent of plume related volcanism within Zealandia. Our work has provided the first offshore reconnaissance geological mapping of the Zealandia continent, of critical importance for understanding the Mesozoic geological history of pre-breakup Australia, New Zealand and New Caledonia, which in turn is the basis for exploring the mineral potential hosted within these regions.

NSW Talk - A New Integration Approach Led to the Discovery of a New Deep-seated World-classPorphyry Copper Deposit

Wednesday, June 19, 2024

Title: A New Integration Approach Led to the Discovery of a New Deep-seated World-classPorphyry Copper Deposit

Presenter: Hojat Shirmard

Date & Time: Jun 19, 2024 @ 1800



The discovery of a new deep-seated world-class porphyry copper deposit named Sereydoun resulted from a distinctive approach to processing, analyzing, and interpreting airborne geophysical data and satellite images in the cluster of Sarcheshmeh copper porphyry mine. This area, which was becoming a tailings dump for the Sarcheshmeh mine, has now become one of Iran's largest porphyry copper deposits after drilling more than 100,000 meters of exploration boreholes, with a reserve of approximately 3.5 billion tons of copper, an average grade of 0.4%, and a cutoff grade of 0.15%. Several porphyry and epithermal copper and gold potential regions were also introduced for further investigation. Following the lithogeochemical survey, interpretation, and integration of the data, the ideal exploratory drilling locations for Sereydoun were determined. The approach used in this study can play a significant role in other places looking for epithermal and deep porphyry copper and gold deposits.



Hojat is a PhD candidate in the EarthByte Group, School of Geosciences, University of Sydney. He holds a MSc degree in Mining Engineering – Mineral Exploration from the University of Tehran. He has experience doing more than 200 mineral exploration projects in different districts of Iran including geophysics, remote sensing, geology, and geochemistry. He has a track record of being involved in discovering a variety of ore deposits through a combination of fieldwork, processing, analysis, integrating a variety of exploration data in industry-based projects. He is now working on “Spatio-temporal Data Mining in Mineral Exploration”. His research has implications regarding developing sustainable mineral exploration in the era of the green energy transition.

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.

Liquid Integrity System (LIS) have been developing methods for detection of defects in liquid storage sites since being founded in 2012. These sites have varied from potable drinking water sites to acid tailings and everything in between. Drawing on a background in electrical geophysics and a desire to improve leak detection while minimising impact to the client’s operations, LIS has developed equipment for monitoring and surveying a wide variety of sites. Our biggest challenge over these years (like many tech-based business) has been ongoing development and adaption – our clients continuously push us to expand into new detection scenarios. In this talk we will discuss the range of techniques that we have developed, and describe some of the varied settings that we have worked in. There is a lot to talk about and lots of stories that we think most field geophysicists can relate to.

Magnetotellurics: Practical Survey Design and Model Assessment

Monday, May 6, 2024

Workshop Overview:
Gain an understanding of the magnetotelluric (MT) method, including survey design, model resolution, and the pros and cons of different modelling approaches. Learn how to identify and assess key indicators of data and model quality. The workshop is structured around a synthetic MT dataset over a hypothetical porphyry deposit. By interactively working through the data, participants will see the impact of different choices they make about survey design, station spacing and 1D, 2D or 3D modelling on the final results.
Participants will leave the workshop equipped to understand the strengths and limitations of their MT models and to interact more knowledgeably with MT contractors and consultants.

Who should attend:
The workshop is designed for anyone who commissions or works with MT data and models in the exploration workflow, including:

  • Geophysicists who work with MT data and models but may not produce the models themselves
  • Geologists or other geoscientists who use MT models in their exploration strategy

No existing expertise in MT, mathematics or geophysics is required, but a willingness to work through geophysical data and concepts is assumed. The workshop is interactive and participants will analyse provided data but no special software is needed.

Learning Objectives:

  • Conceptually understand the MT method, including how different Earth structures affect MT data
  • Learn key QA/QC criteria to assess MT data and models
  • Observe the impact of dimensionality and strike on MT model reliability
  • Compare resolution of features in 1D probabilistic models, 2D models and 3D models and with different survey designs.

Workshop Facilitator:
The workshop is presented by Dr Kate Selway of Vox Geophysics. Kate is internationally recognised as an expert in MT and spent more than 15 years working in university research and teaching positions, including at the University of Adelaide, Yale, Columbia University, the University of Oslo and Macquarie University. She has modelled and published on MT data she has collected from Australia, East Africa, North America, Greenland and Antarctica. In 2022, Kate founded Vox Geophysics with a goal of helping mineral explorers to maximise the value gained from their MT data.
