2016 | Skripsi | FMIPAThe result of Analysis from one dimensional modeling of Controlled Source Audio Frequency Magnetotelluric (CSAMT) data have been done to determine the location of fault structure and mineralization zone in Ciguha field, West Java. Field data in the form of time series is processed to produce an apparent rho and fase against frequency curve. Analysis of the process is done by using a source effects correction to find a solution for the modeling . The results of resistivity cross section is obtained indicates that the fault zone and mineralization with resistivity values ranging 1000 – 10000 ?m. The response of CPK 550, CPK 1100 and CPK 1650 line obtained high resistivity values correlate with Kubang Cicau fault, Ciguha and Cepak Kawung fault fill by mineralization. The model has three lithology, which are: andesite breccia (resistivity 500 to 10000 ?m), tufa rock a little sand (resistivity 10 to 50 ?m), and third layer (resistivity 50 to 500 ?m) is a dacite rock.
