CSIRO-NTGS Tanami Project: aeromagnetic interpretation of the Tanami Region - Geophysical Data

Abstract

The Tanami Region is located approximately 600 km northwest of Alice Springs. The Tanami Region hosts the world class Callie deposit and is highly prospective for gold. In 2018 the NTGS Tanami Region Airborne Magnetic and Radiometric survey was acquired to improve pre-competitive geophysical data in the area.

This new survey, along with 72 aeromagnetic, 32 radiometric and 2 gravity surveys acquired by industry and legacy regional geophysical surveys acquired by government, were reprocessed and filtered; these data are provided here. All geophysical data sets were then used to produce a new seamless solid geological interpretation of the 1:250,000 TANAMI and THE GRANITES map sheets, as well as parts of the MOUNT THEO, MOUNT SOLITAIRE and HIGHLAND ROCKS map sheets, which is also available in DIP021.
