1967 Hanson River Seismic Survey - Seismic Acquistion, Processing & Interpretation Report

Abstract

A simultaneous reflection-refraction reconnaissance weight drop seismic survey was conducted in the Hanson River Area, NT. The depth point method utilising a 5 fold stack and simultaneous one way refraction recording technique was used. The seismic survey followed on from previous gravity and magnetometer surveys suggesting the presence of a structural depression. The results of the seismic survey confirmed that the eastern gravity minimum of the Lander Gravity trough represented a structural depression. It also determined the extent of the structural depression, with a maximum thickness of the sedimentary section of about 7100 feet (Horizon 'D' at station 210 Line R-1). A major fault was also mapped in the south-western part of the prospect area. Horizon maps, migrated and enhanced stacks and fortnightly operations reports are included with the survey data.
