The Analysis Of Geological Characteristics In Mantewe, Tanah Bumbu Regency, South Kalimantan, Indonesia

摘要

Every region has certain geological characteristics and history in terms of geomorphological aspect, stratigraphy and geological structure. One of the functions of knowledge on geological condition of a region is to determine natural resources potential in the region. The location of this study was Sukadamai Village, Mantewe Sub-District, Tanah Bumbu Regency. In Tanah Bumbu Regency, there are many open mine areas with varying pit diameters, including in Mantewe Sub-District. To determine the geological condition of the research location, observation was performed using geoelectricity measurement and field geological observation methods. Based on data analysis, it's determined that: a) The geomorphology of the research location consists of undulating terrain unit and sloping terrain unit; b) The lithology in the research location consists of 4 units, i.e. layered limestone unit, sandstone unit, claystone and shale intercalation unit and coal and shale intercalation unit; c) The geological structure in the research location is fold, i.e. Mantewe fold, which is syncline and reverse fault is estimated to be Mantewe; d) Mantewe fold is a plunging asymmetric fold with a plunge to the south and a tilt around 8~0.
