Batu Bedil
Lokasi: Desa Cibeber, Kecamatan Cibeber, Kabupaten Lebak
Rock Formation:
Geologically, the rock found is basal volcanic rock as a result of Pleistocene volcanic activity. This rock has characteristics of dark gray color, fine porphyritic texture, hypocrystalline, inequigranular, composed of plagioclase minerals, k-feldspar, quartz, pyroxene, and volcanic glass mass. This basal lava is observed to have a columnar joint structure with a diameter of ± 50 cm, and is found in a fallen condition which is likely a result of collapse. In terms of geological age, the formation of this rock is adjacent to the mineralization in Bayah which is of Pleistocene age.
