Abstract

This depth to basement point data set consists of a compilation depth values (meters below the topography) of basement geology buried beneath younger flat-lying cover material. The depth values are sourced from drill hole data, magnetic depth estimates and seismic refraction data. Drill hole data was compiled from a number of sources and consists of holes that entered basement only. The data consists of: - Mineral, Stratigraphic and Coal drill holes sourced from the Queensland Department of Mines and Energy's Interactive Resource and Tenure Maps system (http://www.dme.qld.gov.au/mines/tenure_maps.cfm) - Drill holes included with a GIS of the North Queensland Gold and Base Metals Study (Georgetown) sourced from the Queensland Department of Mines and Energy web site (http://www.dme.qld.gov.au/mines/seqgis.cfm#Georgetown) - Drill holes from the North-West Queensland Mineral Province Report. Seismic data depth estimates were generated from refracted first break seismic data for the North Queensland seismic lines 06GA-M4, 06GA-M5 and 07GA-IG1. Magnetic depth estimates were sourced from the following: - Magnetic depth determinations from the North-West Queensland Mineral Province Report. - Estimated depths to magnetic basement Springvale and Boulia 1:250 000 sheet areas. - Depth to magnetic source estimates from airborne magnetic profile data using the Naudy method. - Depth estimates from forward modelled profiles extracted from a magnetic grid using a dipping dyke as the source body.
