Despite an active fault zone, the amount of deformation on the landscape affected by tectonic processes is largely unknown. In the study, we used morphotectonic analysis from geomorphic indices to evaluate tectonic activity across Khuang Kom and Ban Kho faults, the two main active faults along the west of the PEZ. These faults are bounded by high terrains in the west and by Mueang Pan sub-basin in the east. A high-resolution digital elevation model was used to extract topographic and hydrologic characteristics across the study site. We primarily analyzed two geomorphic indices of mountain front sinuosity (Smf) and stream length-gradient (SL). The combination of these indices potentially indicates the degree of fault activities and the implication of deformation and tectonic processes. The morphotectonic analysis revealed that the lineament patterns of Khuang Kom and Ban Kho faults mainly trend in the N-S direction. Most drainage patterns are parallel and rectangular drainage patterns, indicating numerous joints and minor faults. Analysis of geomorphic indices from these faults shows that the value of Smf varies from 1.02-2.04, and 89% of the study site is considered an active mountainous area. The value of SL mostly ranges from moderate to high gradient meters near the base of the mountain. Our finding suggests that the location of two abutting faults experiences the highest level of rock uplift and/or deformation from oblique-slip fault movement due to the effects of lithologic contact and intersecting fault networks. Our study optimally provides an insight into the advantage of using topographic analysis and geomorphic indices as a tool to estimate tectonic activity and evaluate the potential deformation in the region","PeriodicalId":215907,"journal":{"name":"International Journal of Geology and Earth Sciences","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139371788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research area is in Arinem area and its surrounding, Garut Regency, West Java. Arinem and the vicinity was the location for early stage of research program of mineralization in Papandayan area. This area has good mineralization, and according to previous studies, is a low sulfidation area with the presence of pyrite, chalcopyrite, galena and sphalerite (Antam, 2014). The presence of galena and sphalerite mineral has suggested that instead of low sulfidation, the area may be in intermediate sulfidation zone state supported by other data such as quartz breccia, banded quartz and shear as control structure. Lithology in the area consists of breccia Quaternary and lava unit of Jampang formation in Miocene and unit of andesite and basaltic in Quaternary and intrusion of dacite, andesite and diorite. The alteration and mineralization of research area was classified as propylitic alteration zone with the presence of chlorite, epidote and calcite mineral, argillic alteration zone with montmorillonite, kaolinite mineral, silicic alteration zone with the presence of quartz-sericite, a bit of calcite mineral. The observed ore minerals are pyrite, chalcopyrite, galena, sphalerite. The geological structure was controlled by horizontal fault in almost north-south direction of N 170O-180O E and northeast – southwest horizontal fault in N 40O – 50O E, while the mineralization zone was controlled or following fault pattern of N 170O - 175O E. The epithermal deposit of the study area can be classified as intermediate sulfidation epithermal deposit for zones with galena and sphalerite mineral particularly on several locations near fault zones and brecciated quartz. Meanwhile, the study area is generally low sulfidation epithermal type deposit.","PeriodicalId":215907,"journal":{"name":"International Journal of Geology and Earth Sciences","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133898716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Binuang area located in South Kalimantan is an area where coal carrier formations, namely the Warukin Formation and the Tanjung Formation, are well exposed. Sampling of coal was carried out using a channel sampling method from the youngest coal in the Warukin Formation to the oldest coal in the Tanjung Formation. The methodology applied in this research uses mineral analysis and adsorption of methane gas to find out the coal facies using a diagram conducted by previous researchers. There are two types of coal facies in the Warukin Formation, namely coal facies delta plain wet forest swamp and delta plain fen. In Tanjung formation, the coal facies that develops is delta plain wet forest swamp and delta plain fen. Changes in coal facies will cause the different ability of methane gas adsorption. Coal with a depositional environment (facies) of Delta wet plain swamp has more excellent adsorption of methane compared to adsorption of methane gas in delta plain fen facies.","PeriodicalId":215907,"journal":{"name":"International Journal of Geology and Earth Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116673512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the north of these mountains there is coastal alluvial plain of Java, and in the south there is a depression zone of River Serayu. Overall geomorphostructures of the North Serayu Mountains form a faulted anticlinorium, which one of its flank relatively dipping to the south. In the bottom part of this ranges are such plastic, clastic, clayey sedimentary rocks, Eocene to Miocene aged. While at the upper portion there is a group of elastic, brittle, massive volcanic rocks, andesitic to basaltic composition, Pliocene to Pleistocene aged. A volcano, called Rogo Jembangan stands over the top of the North Serayu anticlinorium, with two of its eccentric cones, namely Mount Telagalele and Mount Pawinihan, situated in the Karangkobar District. North Serayu anticlinorium with a plastic bedrock, which is overlain by elastic, hard, and heavy rock has created such a tectonic model influenced by gravity. Parts of volcano’s body and volcanic rocks blocks in the Banjarnegara Regency area generally move slowly but surely southward over a giant slip plane in the form of orographic fields. Locally, this gravitational tectonic is manifested as mass slides, glides, and creeps, occur any time in the study area. Orogenetics of the North Serayu Mountains is still on going in line with the active tectonism of the Java island, caused by subduction of Indian-Australian plate beneath the Eurasian plate. As long as that is the case, gravitational tectonic will continue to run, and mass movements in the research area will regenerate to happen.","PeriodicalId":215907,"journal":{"name":"International Journal of Geology and Earth Sciences","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117019609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
