Abstract: | Twenty three samples from the pyrophyllite-diaspore deposits have been investigated by x-ray diffraction and geochemical methods. The mineral assemblages belong to the K2O-Al2O3-SiO2-H2O system. Higher concentrations of Ti, Cr and Zr in the deposits as compared with the associated granites and gneisses suggest their laterite type parentage. Existing mineral assemblages are a result of low grade metamorphism (up to about 350°C) of the primary residual deposits containing a kaolinite - diaspore - quartz assemblage. |
