Identifikasi Struktur Bawah Permukaan Di Daerah Panasbumi Kasinan, Kota Batu, Berdasarkan Metode Gayaberat Dan Suhu

Study on geothermal potential in Kasinan, Batu City has been conducted based on gravity method. The aimed of this study is to determine subsurface structure in this field. Data acquisition has performed in 95 point around the location. The study was conducted to obtain Bouguer anomaly and residual anomaly. Upward continuation method performed to gain residual and regional anomaly values. Two types of cross-section modeling have been carried from local anomaly value : AA' and BB' trajectories.The depth of below surface modeling is 2000 meters. The results of modeling confirmed that the rock types compotition on AA' and BB' trajectory are andesite, tuff, and Lava
