Abstract

This research is motivated by the presence of nickel laterite deposit potential originating from various types of lithology in the Bunta sub-district, Banggai Regency, which needs to be followed up to facilitate exploration of nickel laterite. The research area is located at coordinates 122°15'8" - 122°15'18" South Latitude and 0°50'36" - 0°51'18" East Longitude, covering an area of approximately ±441 hectares. The purpose of this study is to understand the geology of the research area and the types of source rocks that have formed nickel laterite deposits in the area. The data used in this research includes geomorphological data, structural data, lithological data, and rock samples. The collected data will produce information on rock types and interpretations of the geological history of the research area. Based on the analysis, the geomorphology of the research area consists of three units: structural hills, denudational hills, and interhill plains. The rock types in the research area include lherzolitic serpentinized rocks and serpentinites, which are part of the ultramafic complex. The observed and developed structure in this area is tensile fractures with a dominant direction of Northwest - Southeast. The results show that this area could be exposed due to oceanic crust subduction, which has uplifted ultramafic rocks to the surface, leading to physical and chemical weathering and the formation of nickel laterite deposits.

Abstract

The research area is located in the village of Tenilo and its surroundings, which exhibit interesting land characteristics and features, making it an attractive site for study. This research aims to analyze and map the geomorphological conditions in order to obtain information related to various geomorphological aspects. The method used is the analysis of geomorphological aspects. The results of this study indicate that the geomorphological units in the area include volcanic hills, denudational hills, and marine plains. The geomorphological aspects of this area are categorized as follows: morphography, consisting of hill and plain units; morphometry, with elevation points ranging from 0 to 350 meters above sea level, and slope gradients from flat to steep; morphogenesis, which includes active morphostructures such as faults and joints, and passive morphostructures such as andesite, volcanic breccia, and alluvial deposits; morphodynamics, characterized by river flow patterns including dendritic and sub-parallel patterns, with river stages ranging from mature to youthful. According to the regional geological map of the Tilamuta sheet, the morphochronology of the research area dates back to the Eocene to Holocene epochs, and the morpho-arrangement of the area is dominated by high erosion processes.
