A saponite from Krugersdorp district, Transvaal
Published online by Cambridge University Press: 14 March 2018
Extract
Available information on the clay mineral saponite shows an amazing degree of variation and considerable discrepancies, probably due to investigation of impure samples. The clay mineral described in this paper was essentially pure and furthermore it seems to represent a magnesium end-member of the montmorillonite group.
Optical, chemical, X-ray, and differential thermal data of this particular saponite are presented, as well as data on some associated minerals, namely, a chlorite, two antigorites, and a chrysotile-asbestos.
The influence of Mg++, as the only natural occurring exchangeable base, on the nature of the X-ray diffraction and differential thermal diagrams leads to some interesting observations.
