Geological interpretation and structural analysis of the northwest Aileron and southwest Davenport provinces

Abstract

This DIP contains a report detailing results from a co-funded, collaborative project between the NTGS and CSIRO along with a solid geology GIS and suite of geophysical images. The project includes interpretation of the NTGS Mount Peake – Crawford airborne magnetic and radiometric survey, which was acquired in 2019 over the northern Aileron and southwest Davenport provinces. This survey links with the 2018 NTGS Tanami Region airborne magnetic and radiometric survey providing seamless high-resolution magnetic and radiometric coverage from the Western Australian border southeast to 150 km south of Tennant Creek. The project provides further processing and image enhancements of the new magnetic and radiometric data and uses these to construct a solid geological and structural map of parts of the MOUNT THEO, MOUNT SOLITAIRE and LANDER RIVER 1:250K map sheets and the whole of the MOUNT PEAKE AND BARROW CREEK 1:250K map sheets. This work seamlessly links with the interpretation completed in the CSIRO-NTGS Tanami Project: Aeromagnetic interpretation of the Tanami Region (NTGS Digital Information Packages 21 and 22).
