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

The process of displacement or movement of slope stability constituent materials followed by the sedimentation process of the deposited material is a landslide event. The negative impact of the landslide if it occurs in residential areas, can cause material and infrastructure losses, or economic losses in the affected area if the landslide products can cover the road access. The purpose of this study was to determine the level of rock mass and its effect on slope stability, and to determine the rock mass quality of the study area. The research area is located in Lolak Dam. Based on the results of the analysis carried out, the conclusion is that the observations starting from station 1, station 2, station 3, and station 4 show moderate-good rock strength. The condition of the discontinuity shows continuity of less than 1 meter, the aperture of discontinuity are open to a bit wide, with varying roughness, namely coarse, and slightly coarse, with the infilling material calcite veins. The level of weathering starts from weathered to very weathered. Groundwater conditions are dominated by discontinuities that have a dry level. Based on the discontinuity characteristic, station 1 has good rock mass class, station 2 has medium rock mass class, station 3 has medium rock mass class, and station 4 has good rock mass class. this value can be used as a reference value for the next stage of decision making regarding the strengthening of the slopes in the study area.

Abstract

This research focuses on the eastern part of the northern arm of Sulawesi to understand the geological conditions, including geomorphology, lithology, stratigraphy, and geological structure. The goal is to determine the geological history and map the geological conditions to identify potential mineral resources. The research methods include a qualitative approach through field observations such as morphology, outcrop descriptions, lithology, geological structure measurements, stratigraphic relationships, as well as an inventory of natural resources and geological disaster risks. The quantitative approach involves calculations and analyses, including geomorphological analysis, petrography, paleontology, geological structure, stratigraphy, and the reconstruction of geological history. The research results identify four geomorphological units (karst, denudational, volcanic, alluvial) and six geological units at the research site. Andesite and volcanic breccia are the oldest units dating back to the Miocene. At the end of the Miocene, uplift and subsidence formed intrusive hills of diorite and limestone. Volcanic activity ceased in the Miocene. In the Pliocene, sandstone formed due to river transport. The rock formation process continues to the present, with alluvial deposit units resulting from the breakdown of rocks around the lake. Geological structure analysis reveals fault lines with the main stress direction from northwest to southeast. Relative fault data indicates fault inclination values suggesting the main stress direction is northwest-southeast. The geological history in the research area began in the Miocene with magmatism and tectonic activities, forming andesite and volcanic breccia units. This history extends to the formation of alluvial deposit units in the present. The research provides in-depth insights into the geological history and potential mineral resources in the region, serving as a foundation for further research.
