Abstract

Bangka Island is a potentially large area of both secondary and primary tin producers, indicated by exploration and exploitation that took place since Dutch colonialism. The need for primary tin exploration in Tanjung Gunung Village, Central Bangka Regency to optimize the acquisition of primary tin resources available by PT TIMAH Tbk. The data collection and processing method is done by measuring the gravity field every point with a lopping system, spacing 250 m and the number of points realized is 474 and using two types of gravity meter devices namely LaCoste & Romberg and Scintrex. The required data is in the form of geological data, rock samples, bouguer anomalies, which will be formed into an anomaly bouger map. Based on the results of research on primary tin mineralization obtained that the stratigraphic formation process is located on the Klabat Granite Formation (TRJkg) in the presence of many granite rock outcrops containing Sn as well as the results of residual bouguer anomalies obtained two interest zones which then made 2-dimensional modeling to find out underwater surface conditions of the study area. This is supported by geological data, actual data on the field and interpretation of the lithology section, so it is recommended to carry out further exploration using the geoelectric methods in the two interest zones to the north and south in the research area.
