| Summary: | Research was conducted in the Totumbang area, Sangalla District, Tana <br />
<br />
<br />
<br />
<br />
<br />
Toraja regency, South Sulawesi, covering an area of ± 13.95km2 (3.1 x 4.5 km), at <br />
<br />
<br />
<br />
<br />
<br />
coordinates 119 ° 53 '15.8688 "E-119 ° 55' 41.2012" E and 3 ° 04 '45.9501 "S - 3 ° <br />

<br />
<br />
06' 27.1855" LS. This study aimed to meet the requirements of a Bachelor of <br />
<br />
<br />
<br />
<br />
<br />
Geology at the Department of Geological Engineering ITB through geological <br />
<br />
<br />
<br />
<br />
<br />
mapping by determining the geomorphology, stratigraphy, structural geology, and <br />
<br />
<br />
<br />
<br />
<br />
geological history of this area of research. <br />
<br />
<br />
<br />
<br />
<br />
Physiographically, the study area is at Western Sulawesi Terrain, with a <br />
<br />
<br />
<br />
<br />
<br />
geomorphic units consisting of Folds Plains Unit scattered from west-east, and Karst <br />
<br />
<br />
<br />
<br />
<br />
Hills Unit in the west, and Intrusion Hills Unit is located in the eastern part. The <br />
<br />
<br />
<br />
<br />
<br />
present morphology indicates mature-old geomorphic stage. <br />
<br />
<br />
<br />
<br />
<br />
Geology of the study area began in the Middle Eocene Epoch characterized <br />
<br />
<br />
<br />
<br />
<br />
by the deposition of Claystone-Sandstone Unit of Toraja Formation in the middle <br />
<br />
<br />
<br />
<br />
<br />
neretic (delta), and then conformably during Late Eocene Limestone Unit of Toraja <br />
<br />
<br />
<br />
<br />
<br />
Formation Limestone Member were deposited triggered by transgression leading to <br />
<br />
<br />
<br />
<br />
<br />
shallow marine environment. And then during the Middle Miocene epoch occured <br />
<br />
<br />
<br />
<br />
<br />
Microdiorite-Andesite intrusion Unit of Intrusive Rock Formastion. <br />
<br />
<br />
<br />
<br />
<br />
Deformation during Late Oligocene led to the generation of anticline and <br />
<br />
<br />
<br />
<br />
<br />
syncline folds with axist trending northeast-southwest, and creation strike slip fault <br />
<br />
<br />
<br />
<br />
<br />
trending northwest-southeast. |
