Correlative geophysical data in the Australian region for use in the MAGSAT project

Abstract

Magnetic data available for use in correlation with MAGSAT data in the Australian region include observatory recordings, first-order and third-order vector regional magnetic surveys, long airborne scalar profiles, and approximately 75% coverage of the continent with detailed aeromagnetic mapping of total intensity. Reconnaissance gravity coverage is virtually complete, and deep seismic sounding refraction and reflection surveys have been carried out at widely scattered locations. There are scattered data from geothermal investigations. Magnetic and gravity coverage is also available over much of the surrounding marine area, and in selected areas in Antarctica. It is planned to use this material in a comprehensive study of the broader lithospheric features of the area.
