SA/NT tech talk: Crustal resistivity of the Mt Gambier subprovince: origins of the Newer Volcanics and implications for exploration in the Western Otway

Tuesday, October 5, 2021

Title: Crustal resistivity of the Mt Gambier subprovince: origins of the Newer Volcanics and implications for exploration in the Western Otway

Presenter: Sam Jennings

Location: Thomas Cooper Room, Coopers Alehouse, 316 Pulteney St, Adelaide

Date: Tuesday 5th October 2021

Time: 5:30 pm for a 6:15 pm start

Cost: Members and students free, non-members $10, includes finger food and drinks

Abstract:

The westernmost Mt Gambier subprovince of southeast Australia's Newer Volcanics Province represent the most recent eruptions of a continental, intraplate volcanic province. Recent magnetotelluric (MT) models in the wider region reveal an extensive conductor beneath Central Victoria as well as a separate, crustally-bound region of low resistivity beneath the Mt Gambier subprovince. To better resolve this western conductor, 49 new broadband MT sites are collected at 25 km spacing and crustal resistivity is modelled using the latest 3D inversion algorithms. An extensive region of low resistivity (<100 Ω m) is revealed and interpreted as the footprint of rising magmatic fluids that cause widespread alteration of Delamerian crust. Spatial alignment of this feature with step-like sub-lithospheric topography lend credence to theories of edge-driven convection and shear-driven upwelling as causal mechanisms for melt generation. A localised zone of even lower resistivity (< 10 Ω m) in the mid-crust beneath the town of Casterton, Victoria is interpreted as small amounts of partial melt. In this presentation, I'll discuss the origins of the NVP, the role of complex basement structures in providing fluid pathways and the implications of a distal melt source for exploration in the Western Otway Basin.

NSW Tech Night: Enhancing statewide geophysics with high resolution company data

Wednesday, October 20, 2021
1800
1900

Titles &  Presenters:

Enhancing statewide geophysics with high resolution company data - Dr Sam Matthews (GSNSW)

Proposed NSW geophysical acquisition 2021-2022 - Astrid Carlton (GSNSW)

Date & Time: Wednesday 20th October 2021, 6:00 pm to 7:00 pm AEDT

Registration: https://us02web.zoom.us/webinar/register/WN_fWZnFRp1Q2q9wOapDGGHkA

Overviews:

Sam’s talk will provide a behind the scenes look at the creation of enhanced statewide geophysical merges incorporating high resolution company data. Following the QA/QC and metadata harvest from decades of legacy geophysics data, a specially created algorithm is applied to provide a quantitative aid in survey selection for inclusion in the merges. A small data workshop is included which highlights how all open-file geophysical data in NSW can be accessed for free through our online portal MinView.

Astrid’s talk will detail the expansive array of regional geophysics occurring throughout NSW from 2021 and into the future. The recent completion of the Cobar AEM and AMR surveys, as well as the Mundi AEM survey are only the tip of the iceberg in NSW. A wealth of regional geophysical surveys spanning a wide range of techniques are also in the works and promise exciting data.

QLD Tech Talk - Randall Taylor - Taylor Exploration Consulting, Principal Consultant. The OZ Min Explorer Challenge 2019: When petroleum explorers go searching for minerals

ASEG Queensland Branch October Technical Talk

Presenter: Randall Taylor - Taylor Exploration Consulting, Principal Consultant.

Title: The OZ Min Explorer Challenge 2019: When petroleum explorers go searching for minerals.

In-person Registration: https://www.eventbrite.com.au/e/randall-taylor-when-petroleum-explorers-go-searching-for-minerals-tickets-175168131597

Online registration: https://us02web.zoom.us/webinar/register/WN_vsI7VuJhRieKY6lTBu_nBw

Synopsis:

In 2019 OZ Minerals released more than 2TB of company data challenging teams from around the world to compete for $1M in prize money by predicting mineralisation locations in the Mount Woods area of the Gawler Craton. The area is best known for the Iron-Oxide Copper Gold (IOCG) Prominent Hill deposit. Three former colleagues, Randall Taylor, Karen Aurisch and Bronwyn Davies with many years of combined petroleum exploration experience, but relatively little direct experience of mineral exploration, joined forces to analyse the data and submit an entry. This talk will present their methodology and results and compare it to the brief public disclosure of the winning entry.

Also on Thursday the 14th of October there is a combined Industry, Society, Early Career and Student Networking function held at the Fox Hotel. The flyer with specific details is below and registration is through the AIG website

Developing a Facies Architectural Outcrop Analog for Kuwait Formation at Jal Az-Zor Escarpment to understand Stratigraphic Controls on Heavy Oil Production Northern Kuwait

Tuesday, September 28, 2021
1830 AEST
1930 AEST

Topic: Developing a Facies Architectural Outcrop Analog for Kuwait Formation at Jal Az-Zor Escarpment to understand Stratigraphic Controls on Heavy Oil Production Northern Kuwait

Date & Time: Sep 28, 2021 06:30 PM in Canberra, Melbourne, Sydney

Presenter:  Salah El-Ekhfifi,exploration geologist,NOC,Libya and  Aimen Amer

Registration: https://us02web.zoom.us/webinar/register/WN_pfNYT0SDTciQCTdFgAwKAQ

Description:

The Goal of this work is to develop an outcrop analog that can explain subsurface reservoir architecture.

This will be established through two methods:

1) conventional facies modeling and

2)forward stratigraphic modeling.

By applying these two methodologies, we will reinterpret an enigmatic elongated geobody in the subsurface and explain, how such feature is an excellent stratigraphic trap

ASEG Queensland Branch August Technical Talk

Peter Fullagar - Fullagar Geophysics Pty Ltd.

Beyond plates - fast TEM inversion using conductive ellipsoids Part2: Inversion

Synopsis


Interpreting TEM data in terms of conductive rectangular plates is effective in many situations. However, not all conductors are planar. Triaxial ellipsoid conductors are an attractive alternative: geometrically simple (corner-free), mathematically tractable at early and late time limits, and able to encompass shapes ranging from plates to elongate lenses to equi-dimensional pods. Accordingly a fast magnetostatics-based algorithm has been developed to compute ellipsoidal conductor responses in both resistive and inductive limits. Inversion of measured data then entails adjustment of ellipsoid parameters. The methodology is suitable for downhole, ground, or airborne TEM, either impulse or step response.
In this second of two presentations, the inversion algorithm is described and illustrated on both synthetic and real TEM data.
