Abstract
Zn and Fe K-edge microbeam XAFS measurements have been made on individual fluid inclusions in quartz at temperatures ranging from 25 °C to 500 °C. Analysis of Zn Kedge XAFS spectra shows that the ZnCl 4 2- complex is predominant at all temperatures up to and including 430 °C. The Zn-Cl bond length was found to decrease uniformly with temperature, up to nearly 2% at 430 °C in comparison to the value at 25 °C. The iron ion appears to be predominantly hydrated up to some temperature between 100 °C and 200 °C. Above 200 °C, iron in the inclusions is predominantly coordinated by chlorine ligands.
