Abstract
Secara administratif daerah telitian termasuk dalam wilayah daerah Kadidia, Kabupaten Sigi, Provinsi Sulawesi Tengah. Daerah telitian terletak pada koordinat 166000 - 191250 mE dan 9881860 – 9865310 mN, zona 51 belahan bumi selatan. Daerah telitian dibagi menjadi 4 satuan geomorfik, antara lain Satuan Perbukitan Sisa Gunungapi, Satuan Lembah Graben, Satuan Dataran Banjir, dan Satuan Dataran/Kipas Kolluvial. Daerah telitian terdiri dari beberapa satuan batuan dari tua ke muda, antara lain Satuan dasit Kadidia, Satuan granit Kambuno, Satuan kolluvial Kadidia, Satuan batupasir endapan danau, Satuan endapan kipas alluvial, dan Satuan endapan alluvial. Struktur yang berkembang pada daerah telitian adalah sesar dan kekar dengan arah umum relatif barat laut – tenggara. Daerah telitian tersusun atas sistem panasbumi oleh intrusi batuan beku plutonik yang membeku dengan aliran panas secara konveksi serta kontrol geologi oleh graben dengan komponen utama sistem panasbumi berupa heat source adalah granit, batuan reservoar berupa granit terdeformasi struktur, batuan tudung berupa granit teralterasi (metagranit) dibantu endapan sedimentasi permukaan. Kedudukan geologi berupa lembah graben yang mempengaruhi munculnya 5 titik manifestasi sistem panasbumi di daerah telitian. Manifestasi yang ditemukan berupa 3 mata air panas, dan 2 kolam air panas. Di daerah telitian nilai total minimal heat loss sebesar 481 kW. Administratively, the location of the studied area is included in Kadidia Village, Sigi District, Bahagia City, Middle Celebes Province. Geographically, it is located between X : 166000 – 191250 and Y : 9881860 – 9865310, zone 51 southern hemisphere. The studied area is devided in to four geomorphic units, there are : Volcanic Skeleton, Graben Dale, Floods Plain and Colluvial Fan Plain. The studied area is composed by several rocks, those rocks from the oldest to the youngest area: Dasit Kadidia Unit, Kambuno Granite Unit, Kadidia Colluvial Unit, Sandstone of Lake Deposits Unit, Alluvial Fan Deposits Unit, and Alluvial Deposit Unit. In the studied area is developed by several geological structures faults and cracks with northwest – southeast general direction. Geothermal system in the studied area is composed by cooling pluton igneous rock with convection heat flow got controlled geology by graben. And has composed by granite as heatsource rock, granite with deformation geological structure as reservoir rock, and metagranite as caprock. Geological setting in studied area is graben dale influencing 5 appariations of geothermal surface manifestations. Those manifestations are 3 hot springs, and 2 hot pools. At studied area has total value of heat loss is 481 kW.
