Abstract

Mount Penanggungan is one of the volcanoes that located in East Java Province, Indonesia, with the current status is a sleeping volcano. Although Mount Penanggungan is not active, it still make an interesting investigation in geological survey, especially to identify the lithological units, due that less researchers took place in Mount Penanggungan. Remote sensing imagery, such as Landsat 8 Satellite imagery series data has been used widely in geology for mapping lithology in general. Remote sensing provides information of the properties of the surface exploration targets that is potential in mapping lithological units. Remote sensing techniques are one of the standard procedures in exploration geology, due to it is high efficiency and low cost. Lithological mapping in Mount Penanggungan area is carried out by analisys Landsat 8 Satellite imagery data with image enhancement techniques, including RGB (red, green, blue) band composite, using band 5, 6, and 7, and band ratio using combination band 4/2, 5/6, dan 6/7. From Landsat 8 Satellite imagery, combines it with the results of surface geological mapping, showed that morphology are mountains, the lithological units are devided to 4 units, andesite boulder, tuf breccias, andesite lava, and andesite breccias.

Abstract

Paleobathymetric study on the Wonocolo Formation in the Tinawun Village Area, Malo District, Bojonegoro Regency, East Java, using microfossil foraminifera analysis from rock samples in that area, aims to obtain information about the depositional environment of sedimentary rocks in the past. The Wonocolo Formation is a rock formation deposited during the Middle to Late Miocene, approximately 11 to 15 million years ago. The analysis of microfossil foraminifera involves the identification and counting of different foraminifera species from rock samples. The method used to determine paleobathymetry is the P/B ratio analysis with the maximum flooding surface (MFS) determined by the maximum abundance of planktonic foraminifera. For the P/B ratio analysis, the classification of planktonic and benthic foraminifera is determined based on their shell morphology. Based on the P/B ratio classification, the paleobathymetry of the Wonocolo Formation can be identified in two main bathymetric zones, namely the Neritic Bathymetric Zone (shallow marine environment) and the Oceanic Bathymetric Zone (deep-sea environment). The research indicates that paleobathymetry in the study area occurred during the Late Miocene (N16, N17, and N18) in an Outer Neritic environment with sea depths ranging from 100 to 200 meters.
