A consistent automated approach to processing South Australia’s drillhole spectral data.
The South Australian Mineralogical Data Package provides spectral data for over 850 drill holes from across South Australia. The package is complementary to the National Virtual Core Library available through SARIG, AuScope and AusGIN portals and makes available mineralogy and spectral scalars in a format compatible with third party software. These data have been compiled in GOCAD to enable analysis and assessment at various scales. To aid interpretation of this point data, 3D voxet interpolations are also available for download.

All open file drill holes in South Australia that have been scanned with the HyLogger™ as at April 2016 were re-processed using a new workflow. This dataset presents all of the HyLogger™ data in the State in a consistent manner using the same spectral libraries.
The South Australian Mineralogical Data Package, a product derived from the National Virtual Core Library, has many geoscientific applications including:
- Mineral exploration can use HyLogger™ data to assist with lithological logging, characterising lithological units and mapping hydrothermal systems
- Petroleum exploration can use HyLogger™ data to determine stratigraphic correlation between petroleum wells and basin evolution
