Abstract
Bora area have a mineralization system associated with geothermal activity, characterized by the presence of veins in the rock. This study aims to determine the indication of ore mineral. The method that used in this research is geological field survey and mineragraphic analysis. The results showed that the vein texture in the study area was in the form of crustiform-colloform, moss, and zoned crystal textures. Mineragraphic analysis results show the mineral content of ore associated with veins in the rock including pyrite, chalcopyrite and covelite. This proves that indication ore mineral in bora area is associated with the veins formed in the rock.
