Bayah dome is one of a gold mineralization area at West Java. Area of mineralization usually have an intensively weathering. Up to now, there is no study of the rock alteration in the dome area by the remote sensing method. Four remote sensing methods to identify mineralization area i.e.: 1) geometric correction, 2) enhancement, 3) manual interpretation which process result: filtering, band ratio, index vegetation, principle component analysis, and false color, 4) classification. Bayah dome has an ellipse form with North West — South East direction. The lineament patterns are North West — South East, North — South and North East — South West direction. Seven units of rock have been interpreted from the principle component analysis. Distribution of the rock alterations are in the center and edge of dome from the classification interpretation. The possibilities of a gold deposit areas which are identified by the alteration and lineament are in the Center, North, North East and East of dome.
