Abstract

This study investigates the influence of bedrock on nickel (Ni) content in laterite deposits in the Lameruru Region, Langgikima District, North Konawe Regency, Southeast Sulawesi Province, Indonesia. The research area is dominated by ultramafic rocks, which are potential sources of laterite nickel. The study employs literature review, field surveys for lithological data collection and representative sampling, petrographic analysis to determine mineral composition and rock types, and geochemical analysis using X-Ray Fluorescence (XRF) to determine nickel content in the rocks. The results show that the bedrock in the study area consists of harzburgite and olivine pyroxenite. Harzburgite, occupying approximately 72.72% of the area, is composed of 54-78% olivine, 15-45% orthopyroxene, 6% clinopyroxene, and accessory minerals, while olivine pyroxenite, occupying about 27.28% of the area, is composed of 27% olivine, 49% orthopyroxene, 17% serpentine, and 7% spinel. Geochemical analysis reveals that harzburgite has higher Ni content (0.10-0.16%) compared to olivine pyroxenite (0.03-0.10%). The distribution of Ni in the bedrock and saprolite is directly proportional, with higher Ni content in harzburgite in both zones. The study concludes that the type of bedrock greatly influences the nickel content in laterite deposits, with harzburgite having a higher Ni content due to its higher percentage of olivine minerals, which are the main hosts of nickel in ultramafic rocks.

Abstract

This study investigates nickel-iron sulfide mineral chemistry and stability from ultramafic rocks in the Kolaka region, Southeast Sulawesi, Indonesia. Sampling was conducted at two Kolaka ultramafic rock outcrop sites in Baula and Wolo sub-districts. The Kolaka Ultramafic Rocks, part of the Kolaka Ophiolite Complex, are primarily composed of lherzolite, harzburgite, olivine websterite, and serpentinites. Sulfide minerals, including pentlandite, pyrite, and chalcopyrite, were observed in these rocks, along with Ni-Fe-rich minerals interpreted as awaruite. Pentlandite, the dominant sulfide mineral, occurs within olivine and chromite replacements, mainly at their rims and serpentine veins. Eight polished sections of ultramafic rocks from both sites were analyzed using EDS SEM to determine the chemical composition of pentlandite. This analysis reveals a variable composition of Ni and Fe, with Ni-rich members more prevalent. Pentlandites from the Baula district have Fe contents of 18.22–27.34 wt%, Ni contents of 32.59–39.10 wt%, and Co contents of 1.24–2.76 wt%, while those from the Wolo district have significantly higher Ni (46.19–53.79 wt%) and Co (2.79–4.18 wt%) contents but lower Fe (8.50–15.18 wt%). Based on the ternary diagram, pentlandites show various formation temperatures (200 to above 600°C). They are separated into two stability groups: Baula’s pentlandite (Ni < 40%, Fe > 18%) with stability temperatures between 200 and 500°C, and Wolo’s Ni-rich pentlandite (Ni > 46%, Fe < 16%) with stability temperatures above 600°C. The formation of Ni-rich pentlandite is attributed to Ni-rich ultramafic rocks reacting with seawater at high temperatures, facilitating efficient Ni scavenging during serpentinization.

Abstract

This research was conducted in Lasolo Islands District, North Konawe Regency. This study aims to investigate the pattern of Ni Fe laterization and determine the prospect area of nickel laterite deposits. The method used is the analysis and interpolation of drilling data to determine Ni distribution, ore thickness, stripping ratio, and deposit prospect area. Drilling data are chemical data of several major elements and oxides obtained from XRF analysis, such as Ni, Fe, SiO2, MgO, and Al2O3, and ore thickness data. The laterization pattern show that the laterite nickel deposits at the research site belong to the saprolitic ore type where Ni tends to accumulate in the Saprolite Zone with Ni content higher than the Cut of Grade (COG) value. The results of interpolation and mapping obtained prospect areas are divided into three namely non-prospect areas (Ni <1.5%), areas with moderate enrichment prospects (Ni 1.5 - 1.8%), and areas with high enrichment prospects (Ni > 1.8%).

Abstract

A rock description training has been conducted at SMK Negeri 6 Kendari to enhance fundamental petrology knowledge and descriptive skills among students in the Mining Geology program. This training involved 47 senior-level students and was implemented through several stages, including preparation, material presentation, rock description practicum, and outcome evaluation via written exam and analytical rubric assessment. The training comprised theoretical and practical sessions focused on the description of three rock groups (igneous, sedimentary, and metamorphic) using hand specimens and thin sections. The analysis demonstrates a significant enhancement in students' comprehension, as reflected in the increase in the average post-test score to 62.02, compared to the pre-test score of 45.74. An improvement in descriptive skills was also evident based on the evaluation rubric, with a greater number of students achieving the "Intermediate" proficiency level, characterized by scores exceeding 39, following the training. Statistical analysis using a paired t-test revealed a p-value <0.05, with the t-statistic substantially exceeding the critical threshold, affirming that the training had a significant impact on improving students’ knowledge and descriptive competencies in rock examination. It is recommended that future training programs focus on advanced modules, particularly those emphasizing rock interpretation, to further enhance students’ proficiency in rock description.
