DETERMINATION OF THE PARTIAL MOLAR VOLUME OF SIO2 IN SILICATE LIQUIDS AT ELEVATED PRESSURES AND TEMPERATURES: A NEW EXPERIMENTAL APPROACH - THE IMPORTANCE OF MELT DENSITY AND SOURCE REGION SIZE

Gaetani G.A.; Asimow P.D.; Stolper E.M. (1998)

This study presents a new approach for determining the partial molar volume and its pressure derivative for a silicate liquid component through an experimental determination of the isothermal pressure dependence of the ...
ELEMENT PARTITIONING DURING PRECIPITATION OF ARAGONITE FROM SEAWATER: A FRAMEWORK FOR UNDERSTANDING PALEOPROXIES

Gaetani G.A.; Cohen A.L. (2006)

This study presents the results from precipitation experiments carried out to investigate the partitioning of the alkaline earth cations Mg2+, Ca2+, Sr2+, and Ba2+ between abiogenic aragonite and seawater as a function of ...
MANTLE PB PARADOXES: THE SULFIDE SOLUTION

Hart S.R.; Gaetani G.A. (2006)

There is growing evidence that the budget of Pb in mantle peridotites is largely contained in sulfide, and that Pb partitions strongly into sulfide relative to silicate melt. In addition, there is evidence to suggest that ...
MINERAL/MELT PARTITIONING OF TRACE ELEMENTS DURING HYDROUS PERIDOTITE PARTIAL MELTING

Gaetani G.A.; Kent A.J.R.; Grove T.L.; Hutcheon Ia.D.; Stolper E.M. (2003)

This experimental study examines the mineral/melt partitioning of incompatible trace elements among high-Ca clinopyroxene, garnet, and hydrous silicate melt at upper mantle pressure and temperature conditions. Experiments ...
MODELING THE MAJOR-ELEMENT EVOLUTION OF OLIVINE-HOSTED MELT INCLUSIONS

Gaetani G.A.; Watson E.B. (2002)

This paper presents a detailed description of an approach for modeling the major element evolution of olivine-hosted melt inclusions. Numerical simulations constrained by experimental data on olivine/melt equilibrium and ...
OPEN SYSTEM BEHAVIOR OF OLIVINE-HOSTED MELT INCLUSIONS

Gaetani G.A.; Watson E.B. (2000)

It is commonly assumed that an olivine-hosted melt inclusion is chemically isolated from the melt surrounding its host crystal. This assumption is probably valid for slow-diffusing, incompatible trace elements, but for ...
PARTITIONING OF MODERATELY SIDEROPHILE ELEMENTS AMONG OLIVINE, SILICATE MELT, AND SULFIDE MELT: CONSTRAINTS ON CORE FORMATION IN THE EARTH AND MARS

Gaetani G.A.; Grove T.L. (1997)

This study investigates the effects of variations in the fugacities of oxygen and sulfur on the partitioning of first series transition metals (V, Cr, Mn, Fe, Co, Ni, and Cu) and W among coexisting sulfide melt, silicate ...
WETTING OF MANTLE OLIVINE BY SULFIDE MELT: IMPLICATIONS FOR RE/OS RATIOS IN MANTLE PERIDOTITE AND LATE-STAGE CORE FORMATION

Gaetani G.A.; Grove T.L. (1999)

This study investigates the effects of variations in the relative fugacities of oxygen and sulfur on the wetting of mantle olivine by molten sulfide. Experiments were performed on mixtures of San Carlos olivine and synthetic ...
