3D Geophysics: Inversion methodology and 3D alteration mapping, with application to North Queensland  

Authors / CoAuthors

Chopping, R. | Williams, N.C.

Abstract

The 2007 North Queensland seismic survey provided a new geodynamic framework and province architecture map for the North Queensland region. Coupled with this, companion geophysical studies provided new understandings of the subsurface of the region. A major focus of the geophysical investigations was the use of potential field inversions. These inversions allow for the mapping of units undercover, predict the extension of geometries away from seismic lines, and also provide a measure of alteration. The North Queensland region also allowed for the testing of both qualitative and quantitative methods to map alteration using geophysical inversions.
