Copper speciation in vapor-phase fluid inclusions from the Mole Granite, Australia

Mavrogenes, John; Berry, Andrew; Newville, Matthew; Sutton, Stephen


X-ray fluorescence elemental maps and Cu K-edge X-ray absorption near-edge structure (XANES) spectra were recorded for individual vapor and brine phase fluid inclusions from the Mole Granite. NSW, Australia. The maps indicate that Cu is concentrated in the vapor inclusions and, at room temperature, distributed uniformly in the condensed liquid. Opaque precipitates in these inclusions do not contain Cu. The absorption spectra identify the stable complexes as [Cu(H2O)6]2+ at 25°C, [CuCl2]1- at...[Show more]
