Geology and Genesis of the Tanco Isolated Hill on the Kerinci Lake, Jambi

Abstract

Kerinci area is a small part of the Barisan Range where the Magmatic Arc Zones and a valley extending from the northwest to the southeast flanked by hills with steep slopes on both of sides that flank it. Isolated hill which is on the Kerinci Lake is the main focus to be studied because its existence is located in the middle of a part of the depression Kerinci Lake. In additions, in the vacinity of the research site there has never been research conducted both of in general and specifically. The research was conducted by interpreting the geological controlled by mechanism on isolated hill morphology forming based on geomorphoogical approach and petrographic analysis. Kerinci Lake on the south side of the research site is indicated as volcano-tectonic lake. The isolated hill is thought to be related to the formation of Kerinci Lake. In saveral location along the path of the Sumatran fault saveral lakes were found which were controlled by this fault. Sumatran fault formation is influenced by strike slip, while the formation of the lake is influenced by extensional stress. Based on it is existence, understanding the location of the research could be done analyzedg of volcanism and structural geology.
