Rare earth elements in volcanic rocks associated with Cu–Zn

It seems likely that ore bearing felsic volcanic rocks have a different genetic history from those that are barren and if this is so these differences should be reflected in their REE geochemistry.A preliminary study of REE in Archean felsic volcanic rocks has shown that those associated with ore have flat REE patterns with well developed Eu anomalies whereas those from barren volcanic rocks

Sulfur radical species form gold deposits on Earth

03 11 2015  gold sulfur ore deposit hydrothermal fluid trisulfur ion The formation of gold deposits on Earth requires aqueous fluids that extract gold from minerals and magmas and transport and precipitate the metal as economic concentrations in ores that are three to six orders of magnitude larger than the Au mean content ∼0.001 ppm of common crustal and mantle rocks
