Abstract

Gold deposits in the West Java area, especially South Garut, enter the hydrothermal system due to Quaternary volcanic activity (Gaffar, 2017). Quartz is the main component of hydrothermal system deposits. Quartz veins have an important role in texture formation which can be used to determine the formation process and texture correlation with ore minerals (Dong et al, 1995). Quartz texture relationship in the study area is interesting to study because it becomes a reference in determining the prospect zone for the presence of precious metals as well as a reference for further exploration. For this reason, the purpose of this study was to determine the relationship between quartz texture and the presence of precious metals and base metals in the study area. The research area is in the Mekarbakti Village area, Bungbulang District, Garut Regency, West Java Province. The study area is included in the Jampang formation which is not aligned with the younger undecomposed unit (Qtv), the lithology of the study area is andesite lava, andesite breccia, lapilli, tuff, andesite intrusion and volcanic deposits. This study uses 3 methods, namely detailed field observations, ore microscopy analysis on seven samples DER_004, DER_005, DER_031, DER_001, DER_003, DER_014, DER_030 and analysis of Fire Assay Atomic Absorption Spectrophotometry (FA-AAS) and Inductively Coupled Plasma – Optical Emission Spectrometry. (ICP-OES) on seven samples DC_000087, DC_000073, DC_000030, DC_000053, DC_000048, MC_000081, DC_000082. From the results of field activities and laboratory analysis, the texture of the research area is divided into seven textures, namely cockade, lattice bladed, saccharoidal, banded comb, brecciated, colloform. The geochemistry of the ore in the study area has a fairly high grade and is associated with quartz vein textures, including brecciated Au texture 3.21 ppm, Ag 74.7 ppm, collorform Au texture 2.605 ppm, Ag 22.9 ppm, lattice bladed Au texture 1.625 ppm, Ag 2.3 ppm, saccharoidal Au texture 1.465 ppm, Ag 1.2 ppm, banded texture Au 1.257 ppm, Ag 2.3, cockade texture Au 0.079 ppm, Ag 2.7 ppm and comb texture Au 0.021 ppm, Ag 1 ppm, on the texture the presence of precious metals was observed and abundant base metals. The texture of the quartz veins in the study area, when compared with the calcifications of Morison, et al 1990, falls into the crystalline quartz zone and the crusstiform – colloform zone.

Abstract

The characteristics of the ore deposit will be greatly influenced by the geological conditions of the area. Surface manifestations of an ore deposit can be identified by the presence of alteration and mineralization zones. The study of alteration zones and mineralization will assist in making an exploration plan for an ore deposit. The purpose of this study is to determine the geological conditions in more detail, and the potential for ore deposits in the study area by alteration, mineralization, and rock geochemistry. Field data collection techniques include geological mapping, and laboratory analysis includes geochemical analysis using the Fire Assay Atomic Absorption Spectrophotometry (FA-AAS) method. The study shows that the lithology of the study area is volcanic rocks composed of andesitic intrusive rocks, diorite rocks, granite rocks, and pyroclastic rocks in the form of breccias. Hydrothermal alteration that develops in the study area can be divided into four zones of alteration type, namely: silicification zone (quartz ± kaolin ± pyrite), argillic zone (kaolin ± quartz), inner propylitic zone (quartz ± chlorite ± epidote ± albite ± pyrite), and outer propylitic zone (quartz ± chlorite ± epidote). Based on the lithology and type of alteration found, it is known that the type of deposit in the study area is part of Cu-Au porphyry deposits in the retrograde and post-mineral alteration stages based on the model of Corbett (1854). Mineralization potential in the study area includes pyrite-sulfide potential, hematite potential with paramagnetic properties, and hematite oxide potential. The results of the geochemical analysis showed that the research area had the highest levels of 0.02 ppm Au, 0.8 ppm Ag, 20 ppm Cu, and Fe <100 ppm.

Abstract

Placer gold has been discovered in Bombana, SE-Sulawesi, Indonesia. The placer gold is not associated with volcanic rock-related gold deposits. This paper discusses the primary gold mineralization as the source of the placer gold. The placer gold is possibly derived from gold-bearing quartz veins hosted by Pompangeo Metamorphic Complex (PMC). Pyrite, chalcopyrite, cinnabar, stibnite and tripuhyite are present. Sheared, segmented vein varies in thickness from 2 cm to 2 m. The veins contain erratic gold in various grades from below detection limit (0.005 g/t) to 134 g/t. At least three generations of veins are identified. The first is parallel to the foliations, the second crosscuts the first generation of veins/foliations, and the third is of laminated deformed quartz+calcite veins at the late stage. The first veins are mostly massive to crystalline, occasionally brecciated and sigmoidal, whereas the second veins are narrower than the first and relatively brecciated. Gold grades in the second and third veins are relatively higher than that in first veins. Fluid inclusion study of quartz veins indicates abundant H2O-NaCl and a small amount of H2O-NaCl-CO2 inclusions. Temperature of homogenization (Th) and salinity of the first vein vary from 184.7 to 245.3 ºC and 5.26 to 9.08 wt.% NaCl eq., respectively. The second generation vein was originated at Th of 132.1-283.4 ºC and salinity of 3.55-5.86 wt.%NaCl eq., whereas the third generation vein formed at lowest Th varying from 114 to 176ºC and less saline fluid at salinity range between 0.35 and 4.03 wt.% NaCl eq. Gold is mainly identified in the form of 'free gold' among silicate minerals. Mineralogically, gold is closely related to cinnabar, stibnite, tripuhyite and possibly minor arsenopyrite. Metamorphogenic gold deposits would be the new target of gold exploration in Indonesia.Keyword: Gold mineralization, orogenic-type, Bombana, Southeast Sulawesi, Indonesia
