Abstract/Notes | A description is given of the paragenetic sequence of mineralisation in relationship to the host rocks and structures at two of the principal hypogene tin deposits within the Eastern Belt of the S.E. Asian Tin Province in its extension in the Peninsula of Western Malaysia. The specific mines on which this paragenetic, geochemical and thermometric study has been based are the Hantu and Gakak Mines at Sungei Lembing, (State of Pahang), and the Waterfall Mine at Pelapah Kanan, (State of Johore). Additional mineralogical, petrochemical and thermal data have been obtained from selected mineralised localities in the Western and Eastern Belts and comparisons are presented. Special emphasis is placed upon the determination and interpretation of homogenisation temperatures, salinity and phase chemistry of fluid inclusions in hydrothermal minerals notably cassiterite, quartz, fluorite and topaz and conclusions are drawn regarding the nature of the hydrothermal systems. The compositional and mineralogical results obtained by the use of Scanning Electron Microscopy on opened fluid inclusions are also discussed. The major, minor and trace element chemistries of cassiterites from the quartz-chlorite, and quartz-feldspar-fluorite veins respectively at the Hantu and Gakak Mines of Sg. Lembing, and the Waterfall Mine are compared with those of the cassiterites from greisenised granite and alluvial and primary deposits from other areas. Regional and local differences in the contents of certain elements in the cassiterites are presented and are interpreted in terms of gross differences in the chemistries of the tin-rich mineralising fluids. The green ferroan chlorites are the principal gangue mineral of the tin lodes in the Sg. Lembing Area. They have been chemically analysed in order to assess their role as a fluorine species. Their combined chemical and XRD data showed them to be a ferroan daphnite. A comparative survey of published data on the contents of incompatible and compatible trace elements between the "tin-granites" and the granitoids which have no known associated tin mineralisation is made and the role of various chemical and mineral discriminants in defining "tin-granites" is discussed. |
