Abstract

The research area is located in the village of Lakea, Lakea subdistrict, Buol district, Central Sulawesi Province. Constituent Lithology within research area consists of three units, these are litodem lava basalt that mainly be composed by lava andesite and lava basalt which partly fractured, volcanic breccia, and tuff; Sandstone Unit mainly composed by sandstone, mudstone, muddy sandstone, and conglomerate; and the last unit is limestone as Coral Limestone Unit. Alteration assemblage is divided into four zones, namely argillic alteration zone (silicon oxide (kuarsa), magnesium aluminum iron silicate hydroxide, potassium aluminum silicate hydroxide dan sodium calcium aluminum silicate (albit), phyllic alteration zone (serisit/muskovit-kuarsa-klorit-feldspar), propylitic alteration zone (Chlorite-serpentine, Illite, Albite, calcian, ordered, Quartz, Muscovite ), and silicified alteration zone (quartz/silica + adularia + calcit± illite). The mineralization is controlled by open space filling with disseminated distribution. Gold mineralization usually associated with pyrite, chalcopyrite, and galena. Mineralization is found fill the major structural pattern with southeast-northwest direction. The fluid inclusion measurement results obtained that microthermometry Th (homogenization temperature when the fluid trapped in the crystals) ranged from 172 ~ 332 °C with a measurement range from 180.9 to 211.0 °C, and the melting temperature (first ice melting Temperatures / Tm) average ranges -1, 2 to 0.8 oC. By calculations, the depth of the formation rate is 79.4 ~ 1712 m, and under pressure about 8.2 ~ 130.3 bar.Keyword : Lakea, Buol, Alteration

Abstract

Ranau Lake as the second biggest lake in Sumatra Island. On Plio-Pleistocene Ranau Volcano (Volcano-tectonic) eruption resulted the formation of Ranau Lake. After the great eruption of Ranau Volcano, grow up another volcanoes like Seminung Volcano, and become a Ranau Volcanic Complex. At the foot of Seminung Volcano often showed sulfur gas burst activity which are indicated by the death of organism in Ranau Lake. The increasing of burst gas and locally earthquacke to be the principle one to predict the possibility of volcano eruption for anticipation and decrease the impact of volcano eruption. The research objective was to determain the characteristics of rocks formation surrounding Ranau Lake using Landsat Imagery.      Keywords: Ranau Lake, Volcano, Landsat Imagery.
