Gold enrichment in hydrothermal sulfides from the Okinawa Trough: An in situ LA-ICP-MS study
2020, Ore Geology ReviewsCrystal habit-directed gold deposition on pyrite: Surface chemical interpretation of the pyrite morphology indicative of gold enrichment
2019, Geochimica et Cosmochimica ActaCitation Excerpt :An implicit hypothesis of this interpretation is that the partition of gold between pyrite and ore-forming fluid is irrelevant to the crystal faces and pertinent surface structures on pyrite grains. However, experimental studies provided direct evidence showing no correlation between gold’s incorporation rate in pyrite and the solution phase concentration of gold ions (Mycroft et al., 1995). Furthermore, a plethora of literature data suggest that the reactivity of pyrite is crystallographic-direction specific (Guevremont et al., 1998; Elsetinow et al., 2000; Zhu et al., 2018).
The nature and partitioning of invisible gold in the pyrite-fluid system
2019, Ore Geology ReviewsMulti-stage precipitation and redistribution of gold, and its collection by lead-bismuth and lead immiscible liquids in a reduced-intrusion related gold system (RIRGS); Dublin Gulch, western Canada
2019, Ore Geology ReviewsCitation Excerpt :One possible mechanism through which the native gold associated with the Pb ± Bi minerals could have formed is through direct precipitation on the mineral surface of existing cosalite (ES) and galena (PHS-1). It is well-known that Au ions can precipitate from hydrothermal fluids as native gold onto sulfide and sulfosalts mineral surfaces (e.g., arsenopyrite, galena, and pyrite; Hyland and Bancroft, 1989; Mycroft et al., 1995; Genkin et al., 1998; Maddox et al., 1998; Scaini et al., 1998; Tauson et al., 2009; Mikhlin et al., 2011). The distinct chemical composition of native gold associated with different “host” minerals (Fig. 11G–H) would require that metals were heavily leached from the “host” minerals such as Ag and Fe from galena.
