Abstract

The Kerinci valley is a graben part of an active tectonic, called the Sumatran fault, stretching from Semangko bay (south Sumatera) to Blangkajeren (Aceh-North Sumatra). his area as volcano-tectonic processes over a long period in this area formed Horst-Graben morphology. This paper aims to determine and identify potential geosite in Kerinci Regency. Thirty-two geoheritage sites have been identified in Kerinci area, and can be divided into three clusters. Cluster one in the North area, Consisting of Mount Kerinci, Lake Gunung Tujuh, Lake Rawa Bento, Mount Belibis, Telun Berasap Waterfall, and Goa Kasah. This area is unique and needs to be preserved as geoheritage sites, Mount Kerinci is the highest volcano in Southeast Asia and Gunung Tujuh Lake is the highest caldera crater lake. Kasah Cave is formed from Mesozoic limestone, which has archaeological value. Cluster two in Center area as Horst-Graben Kerinci, this area is a valley (graben) that stretches for 45 km. This morphology is also known as the result of the movement of active faults known as pull apart basins. The ancient Kerinci lake deposits area also very well recorded on several geosites. Cluster three as paleo-volcano Lempur in the southern part area, this areas have seven geoheritage site, such Danau Kaco and many lake as paleo volcanic cone.
