Geopark Ciletuh terletak di Kecamatan Ciemas sebelah barat Kabupaten Sukabumi, Jawa Barat, Indonesia. Pada Geopark Ciletuh terdapat adanya batuan Pra-Tersier yang tersingkap di permukaan dan juga terdapat berbagai macam struktur yang terbentuk akibat terjadinya pergerakan tektonik di sebelah barat daya Geopark Ciletuh. Penelitian ini dilakukan bertujuan mendelineasi struktur pada Geopark Ciletuh yang timbul oleh adanya perbedaan densitas dengan metode gaya berat. Pada penelitian ini digunakan analisis derivatif first horizontal derivative (FHD) untuk mengetahui keberadaan struktur dan second vertical derivative (SVD) untuk menentukan jenis patahan. Pada penelitian ini juga dilakukan dip estimation dengan metode multi-level second vertical derivative (ML-SVD). Setelah didapatkan data FHD, SVD, dan ML-SVD selanjutnya diintegrasikan dengan data geological section dari peta geologi Lembar Jampang Balekembang untuk dibuat penampang geologi. Interpretasi dugaan patahan memiliki arah orientasi NW-SE dan NE-SW. Hasil penelitian menujukkan adanya indikasi dugaan patahan naik dan patahan turun. Pada analisis terpadu, didapatkan adanya kesesuaian maupun ketidakkesesuaian antara data peta geologi dengan data geofisika.
The research was conducted in Bittuang, Tana Toraja Regency, South Sulawesi Province, as one of the geothermal prospect areas and targets for the initial stage of the Government exploration drilling program for the 2020-2024 period. One aspect of geothermal is the manifestation control structure as a fluid migration path from below the surface. Therefore, identification of existing structures in the Bittuang geothermal area was carried out and confirmed the surface geological structure contained in the Bittuang geothermal geological map. In determining the presence of a fault and knowing its characteristics such as the type of fault, the direction of the dip, and the magnitude of the dip of the fault, the gravity data is processed using the multi-level second vertical derivative (ML-SVD) method. To strengthen the interpretation, the results from the ML-SVD were matched with the data from the horizontal gradient (HG) method and the geological data of the structure of the study area. From this process, there are 27 faults in the Bittuang geothermal area, two of which are indicated as controlling faults for the manifestation of the Balla group and the Cepeng group. This research is expected to describe faults in the Bittuang geothermal area, which can support detailed exploration activities.
