Electrical conductivity of HCl-bearing aqueous fluids to 700 ºC and 1 GPa
Klumbach, Steffen; Keppler, Hans (Contributions to Mineralogy and Petrology, 2020-11-18)Subsurface magmatic–hydrothermal systems are often associated with elevated electrical conductivities in the Earthʼs crust. To facilitate the interpretation of these data and to allow distinguishing between the effects of ... -
The composition of subduction zone fluids and the origin of the trace element enrichment in arc magmas
Rustioni, Greta; Audetat, Andreas; Keppler, Hans (Contributions to Mineralogy and Petrology, 2021-06-15)The partitioning of major and trace elements between eclogite and aqueous fluids with variable salinity was studied at 700–800 °C and 4–6 GPa in piston cylinder and multi anvil experiments. Fluid compositions were determined ... -
Trace element fractionation between biotite, allanite, and granitic melt
Were, Patrick; Keppler, Hans (Contributions to Mineralogy and Petrology, 2021-09-02)The partitioning of a large suite of trace elements between biotite and water-saturated granitic melt was measured at 2 kbar and 700—800 ˚C. To reach equilibrium and to grow biotite crystals large enough for analysis, runs ...
