Abstract

The research area is geographically located at coordinates 0041'30” – 0045'00” North Latitude and 12300'30” – 12303' 35” East Longitude with an area of ± 41 Km2. The method used in this research is scientific exploration by conducting a survey of surface geological mapping. It is carried out in the preparation of literature, tools and materials, the data collection stage is in the form of geomorphological data, stratigraphy, geological structure measurements and documentation. The data processing stage is in the form of laboratory analysis, namely conducting petrographic analysis and processing geological structure data in the form of joints and faults using the stereographic method. The geomorphology of the research area is divided into three geomorphological units, namely; lava flow ridge units, intrusion hills, and fault zone hill units. The study area is divided into three rock units informally in order from oldest to youngest, namely: andesite porphyry unit (early-middle Miocene), granodiorite unit (middle-late Miocene), and modified andesite porphyry unit (middle-late Miocene). The geological structure of the study area consists of joints, Tapaluluo Fault, and Botupololondalange Shear Fault. The geological potential of the research area is in the form of mineralization and rock mining.

Abstract

Monano Subdistrict is one of the sub-districts located in Gorontalo UtaraRegency, Gorontalo Province, which does not have a flood hazard map. Thisstudy aims to determine the geological conditions and create a flood hazardmap. This study collected field data, such as lithological data, plotting dataon flood coordinates of each village, as well as validation data of the floodhazard level. The spatial analysis used in this research scores on flood-proneparameters, such as slope, rainfall, and land use that are overlayed alongwith lithological data. As a result, four geomorphological units are obtained:volcanic hills, denudational hilss, and fluvial and marine plains. From thegeological aspect, four units of lithology constituents are produced, such asandesite units, agglomerate units, sandstone units, and alluvial deposit units.The data also exposes that: slopes range from 0-45o flat to very steep, landuse is covered by settlements, rice fields, shrubs, and forests, as well asrainfall which refers to a very high intensity of rainfall, which is 2771 mmper year. The data obtained produces a flood hazard map divided into threeclasses: low, medium, and high.

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.

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.
