Abstract

This research was conducted in Slango village, Sarolangun Regency, Jambi. This research focuses on analyzing the source of rock origin, namely sandstone found in the Peneta Formation. Sandstone in the study area is quite widely distributed with varied characteristics, so determining the original rock is easy to do. This research was carried out to identify the origin of the rock through petrographic analysis of the sandstone so that the history of the formation of the Peneta Formation itself can be reconstructed. After provenance analysis, the Peneta Formation sandstone comes from the Recycle Orogen, precisely in the Subduction Complex Sources subzone. Apart from that, the Peneta sandstone also shows the origin of the Magmatic Arc. Thus, it is interpreted that the Peneta Formation sandstone has undergone several uplift processes due to tectonic activity and has experienced increased maturity or stability from the Continental Block Provenances. Apart from that, it is also influenced by the weathering process of granite heights or other volcanic materials, whether volcanic or plutonic. Key words: Sandstone, Slango Village, Peneta Formation, Petrography, Provenance

Abstract

Identification and interpretation of landscape lineaments and measurements of geological structural components in rock outcrops have been carried out in order to reveal the development of rock sequence deformation in the study area. This research was conducted in Tanjung Kurung Village and its surroundings. The regional observation area is included in the Manna Enggano Sheet Geological Map (Amin, T, C. et al, 1993), while tectonically it is located in the Bengkulu basin which previous researchers categorized as a fore-arc basin (Sapiie et al ., 2015). This study uses two approaches, namely lineament analysis with national digital elevation model (DEMNas) image interpretation and surface geological mapping with observation of rock outcrops or structures. The DEMNas image used in this research has been accessed from https://tanahair.indonesia.go.id/portal-web which is owned by the Geospatial Information Agency (BIG). The geological structure of the Bengkulu Basin is divided into two general directions, namely the North-West-Southeast and North-East-Southwest directions. Structures that trend northwest-southeast are the Tanjung Sakti fault and the Ketaun fault. These faults are directly related to the Semangko Fault pattern and the Mentawai Fault pattern (Yulihanto et al., 1995).

Abstract

Field observation has been carried out recently in the Tanjung Aur II region, South Bengkulu in order to recognize the structural configuration of rock sequences, employing two fundamental approaches such as the analysis of Digital Elevation Model (DEM) and the surface mapping, particularly on geological structures. The DEM analysis reveals two general patterns of the NE-SW and NW-SE lineaments. The NE-SW trend appears consistent with the structural features resulted from the WNW-directed rifting event, whereas the NW-SE orientation seems coincident with the general strike of the Bengkulu Basin. The field mapping has recognized five types of brittle structures and two ductile deformations. The outcropping brittle deformation includes the Tanjung Aur II-A listric extensional fault, Tanjung Aur II-B listric extensional fault, Tanjung Aur II-C domino extensional fault, and Tanjung Aur II-D listric extensional fault that all strike to NE-SW, and the Air Selali compressional fault which trends to NW-SE. The recognized ductile structures are those of the Air Kenidian Anticline and Syncline, which have a general trend to NW-SE. Importantly, the encountered structures suggest two distinct episodes of tectonic events, transtension and transpression. The transtensional regime associated with the WNW extension of rifting. The synrift event commenced in Paleogene or Paleocene-Eocene time, and proceeded up to Neogene. Hence, the sedimentary influx within the basin had likely been accommodated by the occurring tectonic deformation which resulted in the synrift listric extensional faults. The transpressional regime in the study area led to ductile deformation responsible for thrusting and folding of sedimentary sequences. This post-rifting episode perhaps associated with the onset of Barisan orogeny that allowed inversion of sedimentary basin in Late Neogene or Plio-Pleistocene time. Herein, this tectonic episode is considered as the last event that caused the rock successions to be uplifted and the generated structures in rock units to be exposed at the surface due mainly to denudation and erosion.

Abstract

This study investigates the tectonic deformation history of the Kayu Ajaran area in South Bengkulu through integrated geological structure mapping and Digital Elevation Model (DEM)-based lineament interpretation. The research focuses on reconstructing the sequence of tectonic events that occurred during the Late Neogene within the Bengkulu Forearc Basin, a region known for its complex tectonic setting. Fieldwork and remote sensing analysis identified twelve major structural features, comprising eight folds and four faults. These structures predominantly trend northwest–southeast (NW–SE), indicating a compressional stress regime oriented northeast–southwest (NE–SW). The fold geometries, ranging from upright to steeply inclined types, and fault types, including thrust, reverse, and strike-slip, suggest the reactivation of earlier Paleogene extensional structures during the Neogene compressional phase. Stereographic and kinematic analyses were used to determine the orientation of principal stress axes (σ1, σ2, σ3), supporting the interpretation of inversion tectonics. DEM-based lineament analysis enhanced the identification of structural trends and fault zones, especially in areas with limited outcrop exposure. The study provides a clearer understanding of the progressive tectonic deformation in the region and fills critical gaps in the structural characterization of the Kayu Ajaran area. These results contribute to broader regional tectonic models of southwest Sumatra.

Abstract

In doing slope design, paying attention to slope geometry and soil shear strength is necessary. Determination of slope geometry design also considers the balance between height and slope and production benefits. Research was conducted to analyze slope stability by testing physical and mechanical properties, limit equilibrium, and probabilistic Monte Carlo methods. The surface area of the Overburden stripping area in the 2024 RKP design amounted to 8,172.79 ????2. The production target is 2,000,000 tons of coal with a volume of overburdened material that must be stripped of 29.00, and a Stripping Ratio was obtained with a value of 14.5. The results of the overall slope evaluation of the Old Dump material with an overall slope height of 66.582 m, a slope width of 447.69 m, an overall slope of 8.32? and a bench width of 25 m, a bench height of 6 m with a ratio of 1:3 and a single slope angle of 18.43?. Then, the redesign was carried out and obtained recommendation results of 64.799 m overall slope height, 303.33 m slope width, 1,3.02? overall slope, and 25 m bench width, bench height at elevation 131-110 of 8 m with a comparison ratio of 1:2, single slope 26.57? and at elevation 110-50 of 8 m with a comparison ratio of 1:1.5, single slope 33.69.

Abstract

The influence of geological structures on the distribution of geothermal manifestations in the Subang area and its surroundings, Kuningan Regency, West Java Province, was assessed through an integrated approach combining lineament analysis based on Digital Elevation Model (DEM) imagery, fault and fracture density mapping, surface temperature analysis using Landsat 8 imagery, and surface geological surveys. The results indicate that three main hot spring points are closely associated with high-density fracture zones and active thrust fault systems. The primary geological structures controlling the system include the Ci Monte Fault and Situ Gede Fault, as well as the Ci Monte Syncline and Pamulihan Anticline, all trending east–west and formed due to compressive stress oriented north–south and northeast–southwest. These faults and fractures are strongly inferred to serve as migration pathways for hydrothermal fluids from the reservoir to the surface. The alignment of geothermal manifestations with geological structures highlights the critical role of active fractures and faults as the main controlling factors in the geothermal system. This conclusion underscores that geological structures function not only as natural permeable conduits but also as key indicators in geothermal exploration, especially in tectonically active regions.

Abstract

Geomorfologi tektonik merupakan faktor utama yang menentukan pembentukan bentuk lahan di wilayah dengan aktivitas tektonik sedang, seperti di Ciniru dan sekitarnya, Kabupaten Kuningan, adalah geomorfologi tektonik. Pengaruh ini tampak dari bagaimana struktur tektonik memengaruhi pola sungai serta lanskap pegunungan di kawasan tersebut. Penelitian ini menggunakan pendekatan kuantitatif dan hipotesis, dimulai dari analisis umum kemudian mempersempit ke kajian yang lebih spesifik dan terfokus. Data dikumpulkan melalui analisis morfometri yang meliputi parameter seperti Valley Floor Width to valley height ratio (Vf), Mountain front sinuosity (Smf), Hypsometric Curve and Hypsometric Integral (HI), Drainage Density (Dd), Assymetry Factor (AF) serta Indeks Aktivitas Tektonik (IAT). Hasil analisis menunjukkan bahwa mayoritas segmen wilayah berada dalam kategori aktivitas tektonik sedang, dengan indikator-indikator tersebut menunjukkan deformasi yang stabil dan tidak ekstrem. Nilai faktor asimetri dan Indeks Aktivitas Tektonik menegaskan adanya pengaruh tektonik terhadap bentuk dan struktur geomorfologi daerah. Pola aliran sungai yang dominan berupa bentuk trellis dan paralel menunjukkan pengaruh struktur geologi dan kemiringan lereng yang curam. Selain itu, nilai integral hipsometrik mengindikasikan bahwa daerah Ciniru telah berkembang ke stadium dewasa hingga tua, yang ditandai oleh dominasi proses erosi. Secara keseluruhan, kondisi geomorfologi wilayah ini dipengaruhi oleh kombinasi proses tektonik moderat dan erosi berkelanjutan, yang berimplikasi pada stabilitas relatif namun tetap menunjukkan dinamika deformasi regional. Hasil ini menunjukkan pentingnya pengaruh proses tektonik dalam pembentukan dan evolusi bentang alam di wilayah yang aktif secara tektonik.
