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).
