摘要：This study aims to identify and analyze the potential distribution of gold in East Java. Indicators used were stratigraphy and regional lithology. The research methods were used Digital Medium Format Photo and Digital Elevation Model. the survey method was used in this research is by observing geomorphological processes as lithological products and observing rock stratigraphy. The surveyed areas consist of southern Jember, Situbondo, Bojonegoro and Lumajang. Observation of rock stratigraphy is done by looking at the patterns and types of rocks found in each region. Digital Elevation Model (DEM) is used to determine landforms that are very closely related to the character of the subsurface processes. The results show that there are significant differences in gold potential in various regions in East Java. The difference between the north coast and Java is a sign of differences in rock stratigraphy associated with gold formation. In addition, areas with old volcanic rock lithology have a higher intensity than young volcanic rock lithologies that have not been able to produce gold minerals.
