Kompleks Mineralisasi Cirotan
Lokasi: Desa Sukamulya, Kecamatan Cibeber, Kabupaten Lebak
Rock Formation:
The rock exposed at this location includes:
- Andesite lava, with colors ranging from gray to dark brown, massive, flow-structured, strongly foliated, vesicular, oxidized and filled with calcite, quartz, and sulfide minerals;
- Volcanic breccia altered with lapilli to boulder-sized fragments, composed of andesite and dacite rocks, with a matrix of fine to medium-grained tuff. This volcanic breccia is oxidized and filled with quartz minerals;
- Tuff with colors ranging from gray to yellowish-brown, fine to medium-grained. This rock does not show clear layering, as most of the tuff has undergone weathering processes or hydrothermal alteration.
At the Cirotan Mineralization Complex location, N1900E/800 quartz veins are found in propylitic andesite rocks. These quartz veins are found in two places, in caves at elevations of ±650 m asl and ±900 m asl. The mineralization at this location was formed during the Pliocene period due to the intrusion of microdiorite rocks.
Natural Landscape:
The location features the Kadu Punah waterfall with a height of ±30m, formed due to geological structure.
