EKSPLORASI NIKEL MENGGUNAKAN METODA RESISTIVITY

Nickel is formed from weathering of ultramafic rocks are experiencing, thus forming the distribution of nickel laterite in the earth's surface. In determining the distribution of nickel laterite study area in Sorowako, South Sulawesi, geophysical surveys is performed using the method of Electrical Resistivity Tomography (ERT) is resistivity data that be associated with data the drill. Both the data produced is vertical laterite nickel profile from top to bottom is a layer of limonite (100 ohm.meter - 700 ohm.meter), saprolite layer (0-400 ohm.meter) and bedrock layers (300-700 ohm.meter). Limonite layer has an average thickness of 15 meters. Saprolite layer has an average depth of 12 meters to 45 meters below the earth's surface with an average thickness of 33 meters. Bedrock layer has an average depth of 45 meters below the earth's surfac
