Depth to Basement of Northwest Queensland map

The depth to basement map consists of a compilation of point located depth values, in meters below the topography. The depth values are sourced from drill hole data, magnetic depth estimates and seismic refraction data. The point depths were gridded using the minimum curvature technique with a cell size of 1000 m.


The depth to basement map shows the depth of burial of basement geology beneath younger flat-lying cover material. A companion map "Basement Geology of North Queensland" (GEOCAT No. 68592) shows the basement features for which this depth to basement is referring.


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 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.
