Abstract
The research area is located nearby Batutegi Dam in Batutegi Village, Air Naningan District, Tanggamus Regency, Lampung. This area is predominantly occupied by metamorphic rock, namely mica schist, which is part of Paleozoic Gunungkasih Complex. The geological fieldwork which has been conducted reveals the existence of mineralization potential. Altered rocks found in this area are an evidence of past hydrothermal activity during the orogeny tectonic event of Sumatra Island formation which might have deposited some ore minerals. The altered rocks have experienced argillic alteration type with the presence of illite and secondary quartz. This kind of rocks is mostly associated with iron oxide druzy quartz veins. The structures controlling this area are mainly oriented in NW - SE direction.
