Spectral depth analysis of the Merlinleigh Sub-Basin using potential field data

Abstract

Two-dimensional spectral analysis has been applied as an automated interpretation method to potential field data from the Merlinleigh Sub-basin. This has enabled a comprehensive idea of the main variations in basement depth to be obtained rapidly across the region as an aid to further exploration. The results suggest that the basin contains several fault-bounded troughs which reach about 7 km in sedimentary thickness.
