Abstract

Mapping is an activity carried out by geologists to describe the types of rock that make up it, the structure and history of the formation of an area. The research method used is a combination of qualitative and quantitative methods consisting of literature study, field data collection, data analysis and processing, and research reporting. Geomorphological results of the research area consist of hill units in fault zones, intrusive hill units, and denudational hill units with little erosion. The stratigraphy is composed of the youngest to oldest units: andesite lava units, basalt lava units, and diorite units. The structure consists of a primary structure, namely tarpaulin joints and secondary structures, namely tensile joints and shear joints, which result in the main stress direction being northwest-southeast, and shearing to the left. Geological history began in the Middle Miocene from the formation of diorite intrusive rock (Tmb) which then produced Bilungala Volcanic rock (Tpmb (l)) which was composed sequentially from basalt lava which then became andesite lava. During the Pliocene period, a tectonic phase trending northwest-southeast occurred and produced types of thrust faults and left-slip faults (sinistral). The research area is an active volcanic area with intrusive and extrusive rocks which are thought to have the same source. The influence of tectonic subduction in the Sulawesi Sea is an activity that damages the research area apart from human activity.

Abstract

Gorontalo has two types of limestone, namely reef limestone and clastic limestone. The research area has several formation units, such as Tinombo, Bilungala, Bone Diorite, Pinogu Volcano, and reef limestone. This research produces an analysis of the limestone depositional environment based on microfacies characteristics, as well as identifying the age of the limestone in the area. This research focuses on the Oluhuta and Olele areas in Bone Bolango Regency. Limestone, as the main focus, is a sedimentary rock with calcium carbonate as the main element. The constituent components involve granules, matrix and cement. Microfacies, the study of rock properties through thin sections, helps identify biological and mineral composition and interpret limestone qualities. The depositional environment of carbonate rocks is determined based on component abundance, grain shape, matrix origin, cement type, and rock packing. The methods used are petrography and micropaleontology. The results of research in the Olohuta - Olele area show that the geological conditions include geomorphological units of alluvial plains, coral reef plains and pyroclastic flow hills. The study area consists of Rudstone facies. Based on petrographic analysis, the research area is included in SMF-5, formed in the FZ-4 environment. Based on micropalentological analysis, the Rudstone Facies is aged N12 – N15 (middle Miocene – late Miocene).

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 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.
