Abstract

The research area in Pacitan Regency is one area that has the potential for hydrothermal mineralization in the form of altered rocks and quartz veins formed in Oligocene-Miocene. Magmatic rocks and lineament can be used as an early indication of changes and mineralization. This study aims to identify the dominant direction of vein surface using the Lineament Density Analysis (LDA) method. Shade-relief images created from the ASTER Digital Elevation Model (DEM) help identify alignments in various reliefs and topography. This method can improve straightness in various orientations by simulating topographic lighting in various light directions. The lineament map analysis results that were extracted automatically and manually showed that the direction was NW-SE, N-S, and NE-SW. The results of analysis of field data samples indicate that the alignment direction NW-SE, N-S, and W-E. LDA application to determine the direction of the structure proved to be possible and can be used.
