Abstract

The volcano complex in the Rawa Danau of Banten Province or called the Dano Volcano has an association with the eruption of the Krakatoa volcano, observed from the direction of the ridge lineament. The Dano volcanic eruptions occurred during the Holocene period, causing the accumulation of volcanic material deposits into the northern part of Banten Province. This research area is covering five mountains which are Mount Parakasak, Mount Marikangen, Mount Tukung-Gede, and Mount Karang (sorted from the oldest to the youngest). Field mapping method we use in accordance with previous research and literature studies, as well as the results of the analysis in the form of the senses and geomorphology, stratigraphy, geological structure, and petrography to conclude volcanic facies in the Rawa Danau and surrounding areas. The results of the study showed that there were 4 volcanic facies around the Dano Volcano area. The central facies comprise of dome of Mount Parakasak with steep morphology while the proximal facies with andesitic lava. The structural geology feature formed from sheeting joints in the Southwest-Northeast direction with azimuth of N15° E/44° and tectonic fractures with Northwest-Southeast direction with azimuth N135° E/70° with steep morphology. The medial facies is tuffs and tuff breccias with gentle slope morphology, and the distal facies only have mud deposit, clay lithology with flat morphology. Rawa Danau in this study is located in the distal zone which consists of swamp deposits resulting from the destruction of the surrounding volcanic material.
