Abstract

The research area has a highly complex diversity of igneous rocks, predominantly consisting of fresh rocks, making it suitable for geochemical analysis. The research on the petrogenesis of igneous rocks is located in the Tanjung Kramat area and its surroundings, Hulonthalangi District, Gorontalo City. The aim of this research is to analyze the geological conditions of the study area, analyze magma affinity, and the tectonic setting of the formation of igneous rocks in the study area based on X-Ray Fluorescence (XRF) geochemical data. The methods required to achieve this research include observations of the geological conditions of the study area (lithological observations, outcrops, and rock sample collection), and laboratory analysis (XRF geochemical). The stratigraphy of the study area consists of four units, ordered from youngest to oldest, namely: alluvial deposit unit, limestone unit, porphyritic andesite unit, and granite unit. Geochemical analysis shows a tholeiitic magma affinity for the J.TK15 sample and calc-alkaline for the J.TK20 sample, with a tectonic setting of island arc calc-alkaline basalt, originating from a subduction zone or orogenic zone.

Abstract

This study examines the geomorphological characteristics of the Juriya people's gold mining area, Gorontalo Regency, which includes topographic variations, slopes, river flow patterns, river stadia, and geomorphological units. The research area is divided into four main morphometry types: Lowland, Inland Lowland, Low Hill, and Hill. Slope analysis identifies zones ranging from flat to very steep, indicating different levels of slope stability and areas with a high risk of erosion. The results of the river flow pattern analysis showed the dominance of parallel and dendritic patterns, with a "V" shaped valley in the young stadia and a "U" in the adult stadia. The geomorphological units in the study area consist of the Volcanic Hills Unit, the Denudional Hills Unit, and the Aluvial Plains Unit, each of which has unique lithological and topographic characteristics and affects land use and environmental stability. This study shows that mining activities can increase the risk of erosion and land degradation in areas that are not protected by vegetation, especially on steep slopes. This research contributes by providing geomorphological data that can be used as a reference for sustainable environmental planning and management in the mining area. These results can strengthen efforts to mitigate environmental risks and support responsible land use in people's mining areas.

Abstract

Dambalo is a village located in Tomilito sub-district, North Gorontalo Regency, Gorontalo Province. This study aims to identify and describe the geological characteristics of the Dambalo area and its surroundings. The study focuses on geomorphology, stratigraphy, geological structure, and geological potential. The methods used include field observation and laboratory analysis. Field observations include geological mapping, rock sampling, and measuring geological structures using a geological compass. Meanwhile, laboratory analysis was carried out to determine the mineral composition, rock texture and rock name through petrography and stratigraphic analysis. The results of the study indicate that the study area is stratigraphically composed of the oldest to the youngest lithological units, namely porphyry andesite units, volcanic breccias, and alluvial deposits. The dominant geological structure is tensile fractures (tension fractures) with three main orientations. The geological potential in this area includes C-type mining materials, which mainly consist of porphyry andesite rocks, which have economic value for the construction industry. However, this area also has the potential for landslide hazards, namely in areas with steep slopes. This research is expected to contribute to the management of natural resources and mitigation of geological landslide disasters in Dambalo and its surroundings.

Abstract

Reservoir rocks are subsurface rocks that are porous and able to store and flow groundwater that can be utilized by the surrounding community. The rocks that function as groundwater reservoirs in the Bintalahe area are limestone. Almost the entire research area is composed of limestone so it is interesting to study. Gorontalo is located on the northern arm of Sulawesi which is bordered by two provinces and two seas, namely North Sulawesi Province in the east, Central Sulawesi Province in the west, Tomini Bay in the south and the Sulawesi Sea in the north. Gorontalo has interesting geological diversity to study, especially in Bintalahe Village. This study aims to analyze the porosity value of each limestone facies in the research area. The methods used are field observation and laboratory analysis as well as analysis of the specific gravity of coarse aggregate. The results of the study consist of three limestone facies, namely mudstone facies, batupakes facies and pumice facies. The potential of limestone in the Bintalahe area as a groundwater reservoir is in the category of poor to quite good.

Abstract

The Trans Sulawesi Road in Olohuta Village, Kabila Bone District, is a crucial route connecting Gorontalo and North Sulawesi. Given the steep roadside slopes, geological analysis and slope stability assessments are essential to prevent landslides that could disrupt access. This study evaluates geological conditions and slope stability using the Rock Mass Rating (RMR), Slope Mass Rating (SMR), and Safety Factor (FK) methods. Geological mapping reveals dacite rock formations within a fault zone, with a Northeast-Southwest structural orientation. RMR analysis classifies slope 1 (RMR = 62) and slope 2 (RMR = 57) as "good." SMR analysis indicates partial stability, with slope 1 experiencing Direct Toppling (20.47%) and slope 2 undergoing Flexural Toppling (18.52%), resulting in SMR values of 58.25 and 53.25, respectively. The Bishop Method shows low safety factors, with values of 0.59 for slope 1 and 0.56 for slope 2, indicating instability. To improve slope stability, this study recommends modifying slope geometry.

Abstract

The research location is in the Tolotio area, Bonepantai District, Bone Bolango Regency. This study aims to analyze the characteristics of alteration in the research area. There are a total of 30 random samples taken from outcrops at the research location, using the geological mapping method and geochemical analysis (X-Ray Diffraction) XRD. The results of the study in the form of geomorphological conditions are divided into three morphological units, namely intrusion hill units, steep-sloping volcanic hills and alluvial plain units. The stratigraphy in the research area is divided into three rock units, namely porphyry diorite rock units, crystal tuff rock units and alluvial sediment units. The geological structure of the research area is in the form of faults and fractures, where the fault is a left normal slip fault to the right with a plane structure value of N130 ° E / 56 ° while the line structure is N257 ° E / 44 ° and a rake value of 47 ° and tension fractures that have the main stress orientation direction of northeast - southwest. The alteration types in the research area are divided into four types of alteration, namely propylitic alteration type, phyllic alteration type, argillic alteration type and advanced argillic alteration type.

Abstract

The research location is situated in Mount Pani, Hulawa Village, Buntulia District, Pohuwato Regency, Gorontalo Province. The objective of this research is to determine the geology of the study area and analyze the hydrothermal alteration zones within the research area. The research methods used include surface geological surveys and petrography. The findings reveal that the geomorphological conditions of the research area are divided into one unit, namely a fault zone hill unit. The stratigraphy of the area consists of four units: tuff unit, porphyritic rhyodacite unit, banded rhyodacite unit, and rhyodacitic breccia unit (auto breccia). In terms of geological structures, there are joints in the form of shear joints, which are the result of compression stress, and tension joints. The fault structures in the study area include oblique faults, with the dominant directions being NE-SW and SE-NW. At station M044, a sinistral normal fault (normal left-slip fault) was found; at station M052, a dextral normal fault (normal right-slip fault); at station M079, a sinistral fault (left-slip fault); while fault breccia at stations M02, AL052, and AL29 is interpreted as a sinistral fault with a NE-SW direction.
