Description
Some 71 samples were collected from the Upper Witwatersrand System; from below the Jeppestown Shales to the Upper Kimberley Conglomerates. A total of 74 samples plus standards were analyzed in duplicate for 26 elements; a total of 4000 determinations. A multivariate segmentation technique was developed and applied to the data. All the main stratographic features were succesfully identified. Samples could be back classified with an accurucy of 75% to the 7 segments identified, but this was increased to over 80% for the 3 most significant segments
