Spatial analysis, Induced Polarization, Enhancement


Geophysical data acquisition is principally a function of spatial frequency. In some cases, geophysical acquisitions require enough space to obtain detailed information. However, in certain conditions, such as limited measurement instruments and conditions in the research area, this cannot be done. Several ways can be applied, such as improvisation during data acquisition or when processing data. In this study, a spatial frequency data processing approach has been carried out, which aims to enhance and obtain target anomalies more clearly using spatial filter analysis. The target of this research is the mineralization zone in Mount Parang Karangsambung, Kebumen Regency, Central Java, using the Time Domain Induced Polarization method with four lines using a Dipole-dipole configuration with a measuring spacing of 10 meters. The output of this research is to compare the real data processing of 10 meters spatial field with spatial filter processing to be 5 meters. The processing results show an increase in the sharpness of the resistivity and chargeability images on the 5-meter spatial data. There was an increase in the target image, namely mineralization, as indicated by the response of contrast resistivity and chargeability. The use of spatial filters can increase the resolution of the resistivity and chargeability sections so that the lithology and mineralization zone can be well defined.
