A Low‐Sulfidation Epithermal Mineralization in the River Reef Zone, the Poboya Prospect, Central Sulawesi, Indonesia: Vein Textures, Ore Mineralogy, and Fluid Inclusions

Abstract: The Poboya Prospect lies along the North Northwest -South Southeast Palu-Koro Fault Zone in the central part of the West Sulawesi Arc. The geology of the area consists of the Palu Metamorphic Complex overlain by the Paleogene-Neogene Tinombo Formation of volcanosedimentary rocks, the Celebes Molasse sediment, and Late Cenozoic granitic rocks. Petrography, scanning electron microscope with energy-dispersive spectrometry (SEM-EDS), electron probe microanalyzer (EPMA), and fluid inclusion microthermometry were ca… Show more

“…Recently, Rivai et al . (2019) report percent order of Ag (9.1 wt.%) in chalcopyrite from a low‐sulfidation epithermal deposit in Indonesia. In addition, high concentrations of Te in chalcopyrite are also documented: 350–1,500 ppm in the Metaliferi Mountains porphyry deposit (Cioacǎ et al ., 2014), and 3,200–7,447 ppm in the Uralian massive sulfide chimneys (Maslennikov et al ., 2009, 2013).…”

“…While this study did not determine the Ag concentrations of the Esperanza chalcopyrite, previous studies report that natural chalcopyrite contains significant amounts of Ag: up to 2,211 ppm in the Mantos Blancos (Chile) manto-type deposit (Reich et al, 2013), up to 1,180 ppm in the Metaliferi Mountains (Romania) porphyry deposit (Cioac a et al, 2014), and between 1,414 and 2,900 ppm in the Hilton (Australia) and up to 1.24 wt.% in the Um Samiuki (Russia) massive sulfide deposits (Harris et al, 1984;Shalaby et al, 2004). Recently, Rivai et al (2019) report percent order of Ag (9.1 wt.%) in chalcopyrite from a low-sulfidation epithermal deposit in Indonesia. In addition, high concentrations of Te in chalcopyrite are also documented: 350-1,500 ppm in the Metaliferi Mountains porphyry deposit (Cioac a et al, 2014), and 3,200-7,447 ppm in the Uralian massive sulfide chimneys (Maslennikov et al, 2009(Maslennikov et al, , 2013.…”

“…In other parts of the world, accretionary complexes host diverse types of gold mineralization. These include commonly orogenic‐type gold (e.g., the Maruntau gold deposit, Uzbekistan) and other less common types, such as metamorphosed volcanic‐hosted massive sulfide (e.g., Campbell‐Red Lake, Canada), gold‐overprinted volcanic‐hosted massive sulfide (e.g., Mount Gibson, Western Australia), deformed or overprinted porphyry copper ± molybdenum (e.g., Boddington, Western Australia, Hollinger‐McIntyre, Canada, and Hemlo, Canada; Groves et al, 2003), and epithermal gold mineralization (e.g., Poboya, Indonesia; Rivai et al, 2019).…”
