ALKALI EXCHANGE EQUILIBRIA BETWEEN A SILICATE MELT AND COEXISTING MAGMATIC VOLATILE PHASE: AN EXPERIMENTAL STUDY AT 800°C AND 100 MPA

Frank M.R.; Candela P.A.; Piccoli P.M. (2003)

Many experimental studies have been performed to evaluate the composition of coexisting silicate melts and magmatic volatile phases (MVP). However, few studies have attempted to define the relationship between melt chemistry ...
APATITE IN IGNEOUS SYSTEMS

Piccoli P.M.; Candela P.A. (2002)

Apatite is a minor but ubiquitous mineral in most igneous rocks. Although the modal proportion of apatite in common rocks is generally low, it can reach high concentrations in enclaves, cumulates, and other rocks of low ...
COPPER PARTITIONING IN A MELT-VAPOR-BRINE-MAGNETITE-PYRRHOTITE ASSEMBLAGE

Simon A.C.; Pettke T.; Candela P.A.; Piccoli P.M.; Heinrich C.A. (2006)

The effect of sulfur on the partitioning of Cu in a melt-vapor-brine ? magnetite ? pyrrhotite assemblage has been quantified at 800 °C, 140 MPa, fO2 = nickel-nickel oxide (NNO), log fS2 = - 3.0 (i.e., on the magnetite-pyrrhotite ...
GOLD SOLUBILITY, SPECIATION, AND PARTITIONING AS A FUNCTION OF HCL IN THE BRINE-SILICATE MELT-METALLIC GOLD SYSTEM AT 800°C AND 100 MPA

Frank M.R.; Candela P.A.; Piccoli P.M.; Glascock M.D. (2002)

A vapor-undersaturated synthetic brine was equilibrated with metallic gold and a haplogranitic melt at 800°C and 100 MPa to examine the solubility, speciation and partitioning of gold in the silicate melt-brine-metallic ...
K-FELDSPAR-MUSCOVITE-ANDALUSITE-QUARTZ-BRINE PHASE EQUILIBRIA: AN EXPERIMENTAL STUDY AT 25 TO 60 MPA AND 400 TO 550°C - AN EXPERIMENTAL INVESTIGATION

Frank M.R.; Candela P.A.; Piccoli P.M. (1998)

Felsic magmas may evolve one or more water or chlorine-rich fluid phases which can transport heat and solutes into associated hydrothermal systems and can contribute to alteration and ore deposition. To understand the role ...
LITHIUM ISOTOPES IN THE SYSTEM QZ-MS-FLUID: AN EXPERIMENTAL STUDY

Lynton S.J.; Walker R.J.; Candela P.A. (2005)

The fractionation of lithium isotopes among quartz, muscovite, and a chloride-bearing aqueous fluid has been investigated experimentally at 400°–500°C and 50–100 MPa. Experiments were performed for 15–60 days in cold seal ...
MAGNETITE SOLUBILITY AND IRON TRANSPORT IN MAGMATIC-HYDROTHERMAL ENVIRONMENTS

Simon A.C.; Candela P.A.; Piccoli P.M.; Pettke T.; Heinrich C.A. (2004)

We have examined the effect of pressure on the apparent equilibrium constant, K′, for magnetite solubility (Fe3O4mt + 6HClfluid + H2fluid = 3FeCl2fluid + 4H2Ofluid) and the relative iron-carrying capacities of magmatic ...
