Abstract

The purpose this study is to assess geological conditions and levels of heavy metal pollution arround the artisanal gold mining area in East Tulabolo, East Suwawa District, Bone Bolango Regency, to understand its impact on the environment. This study includes geomorphological, stratighraphic, and geological structural analyses as well as measurements of heavy metal content such as arsenic (As), mercury (Hg), and lead (Pb) in river sediments. The metods used include field surveys, sampling, and laboratory analysis with ICP-MS. While pollution levels were analyzed using the Geoaccumulation Index (Igeo). The result showed that heavy metal concentrations exceeded safe limits, with the highest accumulation found in tailling sediments.. The Igeo analysis indicated a mild level of pollution due to the high concentration levels in the control area. This study emphasizes the need for sustainable waste management and ongoing contamination monitoring, including biota and groundwater sampling, to indetify risks of bioaccumulation and movement of contaminants into the wider eccosystem.

Abstract

This study examines the geomorphological characteristics of Tilangobula Village in East Suwawa District, Bone Bolango Regency, Gorontalo Province, Indonesia, located within the tectonically active Limboto Zone. Through integrated field observations and geospatial analysis—including topographic maps, slope gradients, and drainage patterns—the research identifies structural hills as the dominant geomorphological unit, covering 2.356 km² with elevations ranging from 200 to 600 meters above sea level. The area exhibits two distinct drainage patterns (parallel and trellis) and variable slope gradients (2–140%). Morphogenetic analysis reveals the landscape has been shaped by both endogenic processes (notably oblique faulting, specifically a Normal Left Slip Fault) and exogenic factors (erosion of diorite and quartz diorite intrusions). The lithology comprises intrusive igneous rocks (diorite and quartz diorite), with structural features such as shear joints and faults further influencing the terrain. The findings highlight the interplay between tectonic forces and surface processes in forming the region’s unique structural hills, characterized by V-shaped valleys and steep slopes. This study provides critical baseline data for understanding understudied tectonic landscapes in eastern Indonesia and supports applications in regional geological research and land-use planning. The results underscore the importance of integrating morphographic, morphometric, and morphogenetic analyses to decipher complex geomorphological evolution in tectonically active regions.

Abstract

The study area exhibits diverse geological conditions, one of which is reflected in its geomorphological characteristics that are important to investigate. Olele is located within the southern mountainous zone of Gorontalo and is characterized by hilly to steep terrain. This study aims to identify and classify landform units based on geomorphological analysis. The research method involved field-based geological surveys, including direct geomorphological observations, lithological identification, and geomorphological mapping supported by secondary data analysis. The results show that the study area consists of three geomorphological landform units, namely alluvial plains covering an area of 17.84 ha, reef terrace plains with an area of 17.43 ha, and fault zone hills occupying 1,072.23 ha. The morphography of the area ranges from lowlands to high hills with elevations between 0 and 960 meters above sea level. Slope gradients vary from flat to very steep. Morphogenetic analysis indicates that endogenous processes, particularly tectonic activity, play a significant role in shaping the landscape, as evidenced by the presence of joint structures. Lithologically, the area is composed of unconsolidated alluvial deposits, reef limestone, and volcanic rocks that have undergone weathering and erosion. These findings demonstrate that the geomorphology of the Olele area is strongly controlled by tectonic processes, lithological variation, and surface processes, which together contribute to the development of distinct landform units.

Abstract

This study aims to analyze the geochemical characteristics of andesite rocks within the Tinombo Formation located in Biluhu Barat Village, Biluhu District, Gorontalo Regency. Data collection was conducted through geological mapping and geochemical analysis using X-Ray Fluorescence (XRF) to determine the magma series, magma type, and tectonic setting of the rock origin. The results show that the study area consists of porphyritic andesite and granodiorite units. Geochemical data indicate that the andesite rocks belong to the calc-alkaline magma series, with rock types identified as andesite and basaltic andesite. Geochemical diagrams reveal that the rocks originated from an Island Arc Calc-Alkaline Basalt tectonic setting. The calculated magma source depth ranges from 156 to 164 km, indicating magmatic processes occurring within a subduction zone. This study contributes to a better understanding of the tectonic framework and magmatic evolution in the Gorontalo region.
