Geochemistry of LCT Pegmatites
The whole rock main and trace element geochemical data of the pegmatites is used to decipher the processes which led to the enormous Cs enrichment in the massive pollucite mineralisation. The geochemical study was also designed for potential prediction if a pegmatite potentially might host a yet not recognised massive pollucite mineralisation. Following these goals, the data from the pollucite-bearing Bikita pegmatite field are used for characterisation of the geochemical behaviour of Cs, and is compared to the Western Australian pegmatites. The whole rock geochemical analyses are supplemented by the mineral modes and assemblages gained by automated SEM-MLA (Mineral Liberation Analysis) from the same samples. The Geochemical investigations of the major and minor elements accentuates the solitary characteristics of the massive pollucite mineralisation at Bikita.
