Gold and Other Metals in Graphite SpringerLink

Gold, in particular, becomes concentrated at vein margins, suggesting a hydrothermal transport mechanism and accumulation by carbon. It has been postulated that graphite becomes activated at the vein margins under high temperature conditions and it is this activation that provides sites for the accumulation of metals.Longitudinal projection onto a NW-SE vertical plane of gold ore bodies mined in the central part of the Eastern Lode System, Golden Mile deposit, Kalgoorlie (modified from Gustafson and Miller 1937; Tomich 1959).Note the shallow plunge of the Oroya Shoot and the Oroya Hanging Wall (OHW) stopes, both controlled by D3a reverse Early pyrite and late telluride mineralization in vanadium-rich gold

Hydrothermal Graphite as a Trigger for High-Temperature Orogenic Gold

Typical hydrothermal minerals are pyrrhotite, quartz, biotite, graphite, apatite, titanite, and native gold. The ore mineralogy, combined with microthermometry and Raman spectra on fluid inclusions, has demonstrated three stages of hydrothermal activity: (I) (Gr-1/2) and coarse-sized graphite from gold-bearing veinsGraphite ores are classified as “amorphous” (microcrystalline), and “crystalline” (“flake” or “lump or chip”) based on the ore’s crystallinity, grain-size, and morphology. All graphite deposits mined today formed from metamorphism of carbonaceous sedimentary rocks, and the ore type is determined by the geologic setting.Graphite USGS Publications Warehouse

Graphite

Graphite (/ ˈ ɡ r æ f aɪ t /) is a crystalline form of the element carbon.It consists of stacked layers of graphene.Graphite occurs naturally and is the most stable form of carbon under standard conditions.Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes.Under high pressures The top limestone and the roof kaolin of graphite ore bodies are important indirect indicators of prospecting for graphite deposits in this area.
