Magnetotelluric Investigation Along Seismic Transect 19GA-B1 Results from Round 15 of the Geophysics and Drilling Collaborations Programme EL 32734, EL 32544, EL 32550, EL 32551, EL 32546, EL 32922, EL 32733

Abstract

Zonge Engineering & Research Organization (Australia) conducted a Magnetotelluric (MT) survey at the Barkly project in the Northern Territory for Teck Australia Pty Ltd. A total of 155 MT soundings were carried out, including 116 overnight Broad Band Magnetotelluric (BBMT) sites, 37 shorter duration Audio-frequency Magnetotelluric soundings (AMT), and 2 remote BBMT soundings. The objectives of this work are to better understand the nature of covered Paleoproterozoic stratigraphy by correlating MT inversion results with seismic images from 19GA-B1. The results of this work can be used to interpret major stratigraphic unit, structural features, and estimate the thickness of Cambrian cover in the Barkly Region.
