Sedimentary-hosted copper deposits are the second most important source of copper in the world as well as the most important sources of cobalt and fourth among classes of ore deposits in production of silver. The Neoproterozoic sedimentary succession of the Adelaide Rift Complex, including the Stuart Shelf, is considered as having considerable potential for sedimentary-hosted Cu resources. This dataset provides important stratigraphic surfaces in 3D for a Project Area of Interest (AOI) within the Stuart Shelf as part of GSSA's Sedimentary Copper project with CSIRO. These include: 1) Top of the Pandurra Formation; 2) Top of Beda Basalt, 3) Top of Tapley Hill Formation; 4) Base of Whyalla Sandstone. Each surface has been constructed from drillholes with stratigraphic logs (extracted from SA_GEODATA, that have encountered the relevant stratigraphic units) and outcrops based on SARIG 1:100,000 surface geology. AEM flight lines were also used for the Pandurra Formation surface. The Pandurra Formation and Beda Basalt are a potential source, the Tapley Hill Formation is a potential host, and the base of the Whyalla Sandstone represents a major top unconformity to known stratabound sedimentary-hosted copper deposits on the Stuart Shelf.

All surfaces have been compiled/modelled/constructed in SKUA-GOCAD 2019

      Note: this model is presented as a 'proof of concept' only and their accuracy (spatial or otherwise) should not be relied upon for exploration or other decision making processes.
The linked zip file contains all of the data used to build this 3D model, presented in various file formats.

Positional accuracy:
Horizontal accuracy of the drillholes is variable due to the method of capture (map, handheld GPS, differential GPS, etc); Horizontal accuracy of Formation boundaries is variable (interpreted); Vertical accuracy of the interpolated formation surfaces, topographic and basement surfaces are variable due to resampling (topographic surface), interpretation (formation boundaries) and interpolation.

Attribute accuracy:
Geological attributes are based on interpretation of features in the subsurface which are not directly observable; thus they are subject to alternative interpretations.
