Geochemical Analysis of Metal Minerals on Kuantan Singingi Regency, Riau Province as a Connection part of Bukit Barisan Mountain, West Sumatera, Indonesia

Abstract

The research area is located in Muara Lembu Village, Singingi District, Kuantan Singingi Regency, Riau Province. Located at coordinates 0°25'40.85"S - 101°17'50.82"E and 0°26'45.50"S - 101°19'27.81"E. The research area's landform consists of slightly structural steep, structural sloping hills, and low denudational hills. The study area consists of a rock unit, which is claystone units indicated by a thin layer that formed metal minerals because of the erosional process in several places, which the erosion process transported to the research area. It is supported by thrust slip fault, resulting in gaps at the weak zone and eroded minerals filling and changing the claystone composition. At the same time, the oxidation process occurred in the research area. The geomorphology and stratigraphy analysis results show three types: Slightly Structural Steep, Structural Slooping Hills, and Low Denudational Hills. The results of Genesis and Potential Minerals in the study area consist of carrier rocks from the Claystone Unit. The deposition process can be called Sediment Genesis. The results of X-Ray Fluorescence (X-RF) and X-Ray Diffraction (X-RD) tests showed that the highest minerals are silica (SiO2) with metal mineral potentials such as pyrolusite (MnO2), Muscovite (H2KAL3Si3O12), Graphite (C), Hematite (Fe2O3), Aluminum Oxide / Corundum (Al2O3), Manganese (Mn), Silver (Ag), and Titanium (Ti). This research showed the economic value in the form of iron and steel.
