Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk melakukan pemetaan potensi geologi di Desa Padengo, Kecamatan Duhiadaa, Kabupaten Pohuwato, Provinsi Gorontalo. Desa ini memiliki potensi sumber daya alam yang signifikan, namun belum dimanfaatkan secara optimal karena kurangnya data geologi yang komprehensif. Pemetaan geologi dilakukan untuk mengidentifikasi jenis batuan, struktur geologi, dan indikasi mineralisasi yang dapat dimanfaatkan oleh masyarakat setempat untuk pengembangan ekonomi berbasis sumber daya lokal. Metodologi yang digunakan meliputi survei lapangan dan pemetaan geologi. Hasil dari kegiatan ini diharapkan dapat memberikan informasi geologi yang akurat bagi pemerintah desa dan masyarakat setempat untuk memfasilitasi perencanaan pembangunan yang lebih tepat sasaran, serta mendukung pengelolaan sumber daya alam yang berkelanjutan. Selain itu, kegiatan ini juga bertujuan meningkatkan pemahaman masyarakat mengenai pentingnya data geologi dalam mendukung pembangunan desa.

Abstract

This study was conducted in Longalo Village to determine the rock mass quality using the Rock Mass Rating (RMR) method. The analysis was carried out on five field observation segments. The lithology of the study area consists of granitic rocks, most of which have undergone deformation, especially along the slope areas. Geological factors such as the degree of weathering and structural conditions influence the rock mass assessment. The analysis results show that the RMR values range from 48 to 56, which are classified as Class III or fair-quality rock. Based on this classification, the rock mass conditions in the study area are generally fairly stable but are still influenced by structural features and weathering.

Abstract

This study was conducted in Block “X” of the Pani Gold Project Area, Buntulia District, Pohuwato Regency, Gorontalo Province, with the aim of examining the regional geological conditions, including geomorphology, stratigraphy, and geological structures. The methods applied consist of geological field mapping supported by petrographic analysis. The results indicate that the study area is divided into two main geomorphological units, namely a volcanic hill unit that dominates the area with undulating to steep morphology, and an alluvial plain unit developed along river systems. The stratigraphy of the study area comprises four lithological units, including granodiorite, diorite porphyry, dacite porphyry of Pliocene age, and alluvial deposits of Holocene age. The geological structures identified include fracture systems and normal faults with a sinistral (left-lateral) component trending northeast–southwest, as well as the presence of fault gouge and fault breccia indicating relatively intense deformation. Overall, the geological characteristics of the study area reflect a strong relationship between lithology, geomorphology, and structural controls in shaping the landscape development.

Abstract

Pit X of PT J Resources Bolaang Mongondow is a mineral prospect area that exhibits geological characteristics associated with a high-sulphidation epithermal system. This study aims to identify the lithological characteristics and hydrothermal alteration zoning developed within the study area through the integration of geological mapping, petrographic analysis, and Analytical Spectral Device (ASD) spectral analysis. The results indicate that the study area is composed of four lithological units, namely diatreme breccia, tuff, volcanic dacite, and volcanic andesite. Geological structures are dominated by joints trending northwest–southeast to north–south, which act as pathways for hydrothermal fluid circulation and influence alteration distribution. Based on ASD and petrographic analyses, four hydrothermal alteration zones were identified: vuggy silica zone (±7%), massive silica zone (±29%), advanced argillic zone (±31%), and argillic zone (±33%). The alteration assemblages consist of alunite, pyrophyllite, dickite, kaolinite, illite, and smectite. The spatial distribution of these alteration zones reflects progressive changes in the physicochemical conditions of hydrothermal fluids from proximal to distal parts of the system. The occurrence of vuggy silica and advanced argillic alteration, together with characteristic alteration mineral assemblages, indicates the development of a high-sulphidation epithermal system within the study area. These findings provide important information regarding lithological characteristics and hydrothermal alteration patterns that can be utilized to support geological interpretation and mineral exploration in the area.
