Research is conducted at Sungai Buton area, West Paleleh District, Buol Regency, Mid Sulawesi Province located in UTM WGS 84 Zone 51N and the coordinate is 108000 - <br /> <br /> <br /> <br /> <br /> <br /> 115000 dan 364000 – 367000. The geological mapping activity occupied an area of 10.5 km2 with scale 1:12.500 on the map. <br /> <br /> <br /> <br /> <br /> <br /> Geomorphological unit in research area comprises of Vulcanic Hills Unit where the geomorphological stage is young. The drainage system at this area has rectangular pattern. <br /> <br /> <br /> <br /> <br /> <br /> Stratigraphy of the research area is devided in three units, from the oldest to the youngest; Tuf-Lava Andesite (Mid Miocene – Late Miocene), Andesite Lava Unit (Late <br /> <br /> <br /> <br /> <br /> <br /> Miocence), Diorite Intrusion Unit (Late Miocence). <br /> <br /> <br /> <br /> <br /> <br /> Geological structures which is founded in the research area consists of 2 (two) fault structures. They are dextral strike slip faults which have North west-South east direction and called as Labuton Fault and Labuton 1 Fault. <br /> <br /> <br /> <br /> <br /> <br /> Hydrothermal alteration zone comprise of 4 zones those are Chlorite Zone ± Quartz, Epidote (propilitic), Quartz Zone, Feldspar, Clay Mineral ± alunite, sericite, Calcite, Gypsum, (Advanced Argilic), Quartz Zone , Sericite, Chlorite, ± Muscovite, Feldspar, Clay Mineral <br /> <br /> <br /> <br /> <br /> <br /> (Philic) and Quartz Zone , feldspar, iron oxide ± secondary biotite, sericite , calcite , gypsum and clay mineral with temperature for the mineral formation range between 250O-320OC.
