Mineralization study of Bukit Sambunggiri with the approach of geological and petrogenesys methods in Merawang Subdistrict, Bangka Regency

[摘要] The research area is located in Merawang District of Bangka Regency of Bangka Belitung Province. This research is to find out more detail about Bukit Sambunggiri mineralization and its relation with the availability of mineral cassiterite as tin minerals. The method that will be used is qualitative and quantitative method to some rock samples that exist in the research location and geomagnetic to interpretation of distyributionogminerals . Steps to be taken include literature study, field research, laboratory analysis including mineralogy analysis and microscope observation and geochemical rock sampling using XRD / XRF. The sampling procedure for analysis was done randomly, the rock samples to be tested were chosen based on the number of rocks / lithologies available to be observed and examined for their mineralized content. Regionally the research area consists of a hill which is interpreted as a source of tin minerals. It is hoped that this research can produce existing mineralization models by studying the lithology / rocks, the geological structure of the mineralized carrier and the types of minerals contained in addition to the tin minerals. From the results of petrographic analysis obtained some litologies such as sandstone metasediment and claystone metasediment as well as mineral veins filled by ore minerals. Geomagnetic analysis results from 5 existing line show the distribution of minerals follow the direction of geological structure and the existence of mineral ore. Result of xrf analysis known mineral content is cassiterite, monazite, zircon, ilmenite and iron oxides minerals.
