A method for the stratigraphic classification of Klipriviersberg Group and Allanridge Formation volcanic rocks

The Klipriviersberg Group volcanic rocks are frequently encountered during exploration for the reefs of the Witwatersrand Supergroup, and it is thus important to be able to establish stratigraphic position within the group. A geochemical stratigraphy exists within the Klipriviersberg Group but its application requires analyses of many samples in stratigraphic order. A technique has been developed for the stratigraphic classification of single samples from the Klipriviersberg Group. Using data for the Klipriviersberg Group on the Central Rand, where a complete succession of eight geochemical units is encountered, Discriminant Function Analysis was employed to discriminate between the geochemical units
