Abstract
The process of data collection carried out for 2 months with 4 tracks the number of trajectories of space between the track 300 m and an area measuring 1 km x 4 km. Retrieval of data using a Proton Precession Magnetometer (PPM) model for meode geomagnetic G856 with a space between the measuring point 5 m, and IP Syscal Yokohama for IP configuration method of dipole - dipole with a space between the electrodes 25 m. While the next method of data retrieval using the Phoenix T3 (transmitter) and Phoenix V8 (receiver) for CSAMT method with a space between the measuring point 50 m Data processing is done using software magloc, excel, Res2dinv, CMT Pro Surfer 10 and geosoft montaj oasis. This processing results obtained from magnetization profiles, cross section 2D resistivity and chargebility / PFE, total magnetic intensity map, a map of upward continuation, reduction to the equator maps, resistivity maps and map chargebilitas / PFE. The results of the geophysical interpretation of the integration method is expected mineralized zones are at high magnetic intensity values ( > 45100 nT) for geomagnetic methods, variation value chargebility/ PFE with the resistivity indicates that the mineralization accumulating in argillic alteration zones (low resistivity <100 ohm-m - Chargebility / PFE high > 200 msec /> 1.8%) and silifikasi (high resistivity > 200 ohm-m - Chargebility / PFE height > 200 msec / PFE > 1.8%). For the resistivity response on CSAMT method has a high resistivity values (> 200 ohm-m) and Low resistivity (<100 ohm-m) with a penetration depth of up to 700 m. From these responses zones - zones of mineralization spread more inclined towards the more thickened than in the north to the south because of structural patterns that influence the trending north-south direction. Mineralized zone is considered sufficient thought to contain potentially economic minerals of gold minerals.
