Formation of Sn-rich granitic magma: a case study of the …
Kafang Cu–Sn deposit in the Gejiu ore district (65 Mt Cu ore at a grade of 1.2% and 32 Mt Sn ore at a grade of 0.6%). We use these data to constrain the source, evolution, oxygen fugacity, and tectonic setting of the granitic magmatism. Zircon U–Pb dating yielded an age of 82.8 ± 0.6 Ma for the Kafang granite.
Origin of granodiorite hosted Neoarchaean orogenic gold ore …
1. Introduction. The ore bearing fluids for orogenic gold deposits world-wide have been suggested to have originated by metamorphic devolatilisation of greenstone belt volcano-sedimentary assemblages of rocks (Kerrich and Fyfe, 1981, Goldfarb et al., 2005, Goldfarb and Groves, 2015 and references therein).For Neoarchaean and …
How Gold Ore is Formed · Genesis
Among such rocks are granite, aplite, gneiss, eurite, quartz-trachyte, syenite, andesite, basalt, diorite, gabbro, diabase, schists, porphyry and slate. These deposits seldom pay to work and in that case can hardly be called gold ores. J. E. Spurr writes—"Native gold has been found in both basic and acid rocks.

Gold ore is also less likely to be exposed to air: 50% of ore blocks from the first and second batch do not generate. The extra batch in badlands generate regardless of exposure to air. Gold ore can replace stone, andesite, diorite, granite, tuff, and deepslate. Any gold ore that replaces tuff or deepslate becomes deepslate gold ore.
