IDENTIFIKASI POTENSI SUMBER DAYA TIMAH PRIMER DENGAN MENGGUNAKAN INDUKSI POLARISASI DAN RESISTIVITAS DAERAH BUKIT PUYUH KEC TEMPILANG KAB BANGKA BARAT BANGKA BELITUNG

摘要

This research is aim to see the prospect of primary tin at Bukit Puyuh area, Tempilang Subdistrict, West Bangka. At the surface of the area not showing any indication of vein existing even the veinlet so clearly as primary tin Porter. One of the exploration method geophysical that used to to detect tin existing is geoelectric method. The geoelectric method that used for this research is polarization induction method or inducted polarization. The work of this induction polarization principles is detecting the occurring of electric polarization on the surface of metal minerals underground. By the result of the field measure gained data in form of mein/ dsceit resistivity and chargebility. The research data is primary data with 5 line as long as 500 metre by using dipole configuration. The result of measuring and tabulation data interpreted by analyzing longitudinal section 2D and 3D modeling result of resistivity value and chargebility with drill data. Interpretation result clarify that primary tin exist marked with resistivity value 700- 1000 ohm.m.The exist of weak zone in every line which indicate as facture, plate that consider as primary tin line. Afterwards to strengthen notion resistivity value overlayed with chargebility value which have a distance value 3-25 Msec. At this distance value found rocks or minerals primary tin Porter. It is can be conclude that at the research area still consist of primary tin potential.
