Abstract

http://dx.doi.org/10.17014/ijog.vol3no2.20082The Mount Patiayam Complex was interpreted by previous researchers as “Patiayam Dome”. That was reasoned by dips following its slope directions. Field data record that lithology of the complex of Mount Patiayam is dominated by volcanic rocks. The summit of the complex is composed of igneous rocks of pyroxene basalt rich in leucite minerals, associated with autoclastic breccia and beds of volcanic breccia rich in pyroxene basalt and pumice, pumiceous breccia, and tuff. Its flanks are composed of epiclastic rocks of lahar and fluvial deposits. Some river valleys, such as Pontang River, locally consist of pyroclastic breccia, autoclastic breccia and pumiceous breccia, that are overlain by marly limestone and black clay of swampy deposits. Based on the rock composition, the volcanism had more dominated geological processes compared with sedimentary. Mineral composition of volcanic deposits of the Mount Patiayam is closer to Mount Lasem volcanic rocks than Mount Muria, i.e. absarockites, shoshonites and trachyandesite. But, based on the long distance between Patiayam and Lasem, about 60 km, those volcanic rocks could not be produced by Mount Lasem. The Patiayam volcanic deposits were produced by its own volcanic activities. Therefore, the complex of Mount Patiayam is a paleo-volcano. The interpretation is also supported by the landsat imagery, showing depression-shapes in a caldera ring-like. There are four caldera features called as Rim 1,Rim 2,Rim 3, and Rim 4, which crosses each others.

Abstract

Geomorphologically, Mount Patiayam is a dome. The dome is characterized by varrying in strike-dips, the dipping layers of the southern part is to south, the eastern part is to east, the northern part is to north and the western part is to west. The summit of the dome is composed of igneous rock of pyroxenic basalt, while fluvial deposits and shale are composing of flanks up to foot of the dome. Based on the composing rocks, there were volcanism processes within Mount Patiayam. The interpretation was also supported by Landsat image that showed depression-shapes in caldera rings-like.Furthermore, Pleistocene sediments contain vertebrate and hominid (Homo erectus) fossils that are exposed at Patiayam region. Those fossils occur within cross bedding structure of pumiceous breccia, fine up to very coarse tuffs, and clay tuffs.
