Abstract

The methodology in this research begins with data collectingprocess, which this preliminary data is then being compiled to determine the next phase of the study. This study covers the geomorphology, stratigraphy, any structural and alteration mineralization observation. The geomorphology of the study area composed ofthe four original forms: volcanic, structural, karsts andfhuvial form. The stratigraphy composed ofseven unclassified litho units and two litodem, namely (from old - young): Halang volcanic breccias unit, Halang sandstone unit, Kumbang andesite lava unit, Tapak volcanic breccias unit, Tapak sandstones, unit Tapak limestone unit, alluvial deposits, and andesite intrusion.

Hydrothermal alterationsformed in the research area are carefully grouped into three types ofalteration zoning and they are argillic alteration, propylitic alteration, and sub-propylitic alteration. The mineralization then is carefully classified as pyrite (FeS3), chalcopyrite (CuFeS), galena (Pbs), bornite (CuFeS2). The macroscopic analysis ofthe structure in the study area based on the alignment ofalleged traces of the geological structure in the form offault, or directions of the fold axis alignment, obtained the general alignment directions trending N 305° E (NW- SE), and N 055 E (NE - SW).

In the research area, the mineralization process is controlled by geological structure such as fault and joint. The appearance of the mineralization is abundant and can be found manyfulfilling the joint zone mainly shear joint trending Northeast - Southwest and Northwest - Southeast, the direction ofjoint sharpness measured in the field relatively trending North - South. This study will emphasize on the measurement and detailed analysis to know more about the gold mineralization process and other minerals controlled by structures patterns. The structural control analysis can really be a good helping hand in locating the mineralized areas because basically the activity and geological structure control process are corridor for magma and the its rest compound that brings minerals, so the methods of mineral ores exploration by structure control can be used in determining ore gold mineralized deposits precipitate on gold deposits system and other minerals on a different area.
