Bushveld Complex Compilation

For exploration and mining companies working on the Bushveld Complex, a comprehensive collection of key data sets, compiled and re-interpreted from public-domain information

Source Data

245 georeferenced maps from public-domain literature and reports

Regional Geology and Reef Outcrops

Regional 1:1000 000 scale CGS geology map and interpreted reef outcrops. 882 line segments including UG2, Merensky, LG, MG and Magnetite Reef outcrops. 868 reef contours down-dip of reef outcrops.

Interpreted Fabric

Interpreted bedding, layering and tectonic fabric. 25722 short linears defining the dominant local fabric.

Points of Interest

765 key points of interest with descriptors and attributes. 5395 orientation readings with assigned lithology and feature measured. 160 kimberlites and related rock types with descriptors and attributes.d

Faults

10133 interpreted fault segments. 715 major or named faults based on maps and literature.

Dykes

5116 interpreted dyke segments assigned to recognised dyke swarms.

Dyke Analysis
