Morphological Identification based on Lineament and Density Pulai Pinang Region and Surroundings Lahat District, Province South Sumatra

Abstract

Morphological identification based on lineament and geological structure analysis has been carried out in Pulau Pinang Village and its surroundings, Lahat Regency, South Sumatra Province. The initial stage in identification uses a remote sensing approach through lineament analysis using DEMNAS data. This research is focused on lineament analysis with Digital Elevation Model (DEM) data to identify geological and morphological structures in the study area. The methods used in the research are observative, analytic and interpretive. The research was conducted with DEMNAS data which was then extracted using PCI Geomatica software and after that it was correlated with geological structure data in the field. Lineament analysis used is the length, orientation and density of the lineament. This study aims to interpret the relationship between lineament data and the results of field data. The research location is controlled by the geological structure, namely fracture and morphology. Based on this research, data obtained, the Pulau Pinang area is composed of fractures which are analyzed to produce a right horizontal fault and 3 geomorphic units / landforms, namely the Irregular Meander Channel (CIM), Steep Slope High Hills (PTBC), Denudasional Hills (PD), and Low Hills (PR).
