By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government. During February and March in 2023, Geoscience Australia undertook the Curnamona Cube Extension Magnetotelluric (MT) Survey in western New South Wales and eastern South Australia. The survey complements the University of Adelaide/AuScope Curnamona Cube MT survey by extending the coverage from the Curnamona Province into the Delamerian Orogen. Geoscience Australia contracted Quantec Geoscience Ltd. and its subcontractor Australian Geophysical Services to conduct the data acquisition and processing. Audio and broadband MT data was acquired at 99 sites on an approximately 12.5-25 km grid with denser sites across known geological structures and along seismic lines acquired by Geoscience Australia in 2022 (L213 Darling-Curnamona-Delamerian (DCD) 2D Seismic Survey, eCAT # 147423). Instruments were set up to record five channels (three magnetic and two electric fields) for a minimum of 24 hours with a target bandwidth of 0.0001 – 1000 s. Processed data show good quality at a majority of the survey sites, except a few sites affected by environmental and cultural noise. The acquired data will be used to derive resistivity models, and to enhance the understanding of the geodynamics and mineral potential in the Curnamona Province and Delamerian Orogen.  This data release contains a field logistic report; processed data in EDI format containing spectra and site locations in shape file and .txt format. Time series data in ASCII format is available on request from clientservices@ga.gov.au - Quote eCAT#147904. Geoscience Australia acknowledges the traditional landowners, private landholders and national park authorities within the survey region, without whose cooperation these data could not have been collected. {"type": "Polygon", "coordinates": [[[140.0, -34.0], [144.0, -34.0], [144.0, -130.2], [140.0, -130.2], [140.0, -34.0]]]} 140.0 144.0 -130.2 -34.0 Darling-Curnamona-Delamerian EFTF – Exploring for the Future Electrical and Electromagnetic Methods in Geophysics Geophysics Published_External magnetotellurics Download Logistic Report (pdf) [47.0 MB] documentDigital Download Logistic Report (pdf) [47.0 MB] PDF Download Project Description (docx) [13.2 KB] documentDigital Download Project Description (docx) [13.2 KB] DOCX Download Processed Data (zip) [3.0 MB] documentDigital Download Processed Data (zip) [3.0 MB] ZIP Download Site Locations (zip) [1.1 MB] documentDigital Download Site Locations (zip) [1.1 MB] ZIP
