Abstract

This study was focus about geology and potential limestone geohazard in study area in Kampung Lambok, Kuala Betis, Gua Musang. The objectives of this study are to produce the general geological map of study area on a scale 1:25,000 and to study the presence of cavity and potential of sinkhole in subsurface condition of study area by using Electrical Resistivity Imaging. Geological mapping was conducted in order to collect surface geological data such as the rock distribution, structural geology and geomorphology. Rock samples were collected for petrography analysis, mainly for identification of the rock types. Geological map shows the locations where rocks are exposed at the Earth’s surface. The geology of the area is covered by limestone, tuff, mudstone and metasediments. Besides, geological map also shows geological feature such as faults and strike dip of rock. The study area is covered by hilly and mountainous. The drainage patterns is dendritic pattern. Electrical resistivity imaging technique was chosen for investigate the presence of cavity instead of other geophysical techniques. The three electrical resistivity lines were done in limestone. PoleDipole and Wenner-Schlumberger array configuration were used with electrode spacing distance of 5 m and the length of 200 m. The resistivity imaging measurement was carried out using an ABEM Terrameter LS 1, which electrodes were arranged in a straight line with constant spacing and connected to ABEM LUND cable. The resistivity data were processed by using RES2DINV and the result displayed as pseudosection. The 2D profile showed the zone of alluvium and hard rock zone.
