Field Trip: From a Carbonate Ramp to Siliciclastic Fluvio-Deltaics in a Tectonically Active Delamerian Cambrian rift. Seismic-Scale Depositional Systems in Outcrop Field Trip

Posted by

On a glorious spring weekend members and friends of the SA/NT Branch were able to participate in a self-drive field trip led by Rhodri Johns and Elinor Alexander.  This was a joint field trip with PESA SA/NT, GSA and the Field Geology Club of Adelaide.  It was an opportunity to investigate the Cambrian evolution of South Australia through spectacular seismic scale coastal exposures along the west coast of the Fleurieu peninsula.  

Although a two-day field trip participants had the option of participating in either or both days.

The first day was spent examining the carbonate ramp deposits of the Sellick Hill Formation and the clastic turbidites of the Carrickalinga Head Formation at Myponga and Carrickalinga.

Critical Minerals Shortages Threaten International Energy Tansition Goals, Reveals GlobalData

Posted by

The global transition to clean energy is gaining momentum, heavily relying on renewable technologies such as solar PV cells and wind turbines, alongside energy transition solutions like hydrogen, energy storage, and carbon capture. This shift has triggered an unprecedented surge in demand for critical minerals, posing significant challenges in achieving international energy transition goals, says GlobalData, a leading data and analytics company.

GlobalData’s latest Strategic Intelligence report, Critical Minerals (2024), identifies several main challenges to scaling clean energy technologies: mineral depletion, resource monopolization, geopolitical tensions, and water scarcity.

Martina Raveni, Strategic Intelligence Analyst  at GlobalData, comments: “The near-term depletion of critical minerals raises concerns, especially as instability in the green technologies market causes price volatility.

‘Attacks on Seismic Surveys Threaten Australia’s Future Energy Supply’

Posted by

Australia’s energy security will be put at risk if decision-makers ignore the science of seismic surveys – a safe and proven technology that is critical for finding and developing new gas supply.

That is the view of Australia Energy Producers (AEP) Chief Executive Samantha McCulloch, who said: “Seismic surveying is a strictly regulated technology that has unlocked Australia’s vast offshore gas resources and delivered reliable energy for millions of Australian homes and businesses for decades.”

“The facts are that Australia’s future energy security will depend on continued exploration for new gas supply to 2050 and beyond,"she added.

“The legislation introduced in the Parliament(recently)is aimed at stopping new gas projects, with no regard for the devastating impact on Australia’s economy and energy security.

Are Electric Vehicles Really Disruptors in the Australian Petroleum Markets?

Posted by

By Max Williamson

Potential buyers and users of EV’s need to be extremely wary and questioning of the claims, counter claims and promo materials being put out by the vested interests.

If UBER is getting completely out of hybrids for its fleet, there must be economic support for EV’s versus hybrids for higher use operators and commercial fleets.

The second-hand market for older model EV’s, including Teslas is dramatically negatively impacted by the age of the batteries therein, the warranties periods remaining on the batteries and the then version of the EV technologies in those vehicles.

Airborne Survey Wraps up in Victoria

Posted by

An airborne gravity survey across southern and eastern Victoria has been completed by Sander Geophysical.

The airborne survey was collaboratively organised through Surveyor-General Victoria within the Department of Transport and Planning (DTP), Geological Survey of Victoria within the Department of Energy, Environment and Climate Action (DEECA) and Geoscience Australia (Commonwealth Government).

The objective of the survey was to collect consistent and evenly distributed gravity measurements. The new gravity data will significantly improve Victoria’s gravity model which is used to provide accurate and reliable heights from GPS positioning.
