EXPERIMENTAL CONSTRAINTS ON THE ROLE OF GARNET PYROXENITE IN THE GENESIS OF HIGH-FE MANTLE PLUME DERIVED MELTS

Tuff J.; Gibson S.A.; Takahashi E. (2005)

The anhydrous phase relations of an uncontaminated (primitive), ferropicrite lava from the base of the Early Cretaceous Paraná-Etendeka continental flood basalt province have been determined between 1 atm and 7 GPa. The ...
MELT GENERATION BY ISENTROPIC MANTLE UPWELLING

Iwamori H.; McKenzie D.; Takahashi E. (1995)

The primary effects of melt segregation processes on isentropic melting paths are studied using a one-dimensional steady-state model. A parameterization of X(T',P) to 9 GPa shows that X, the degree of melting, depends on ...
MELTING EXPERIMENTS ON HOMOGENEOUS MIXTURES OF PERIDOTITE AND BASALT: APPLICATION TO THE GENESIS OF OCEAN ISLAND BASALTS

Kogiso T.; Hirose K.; Takahashi E. (1998)

Melting experiments on synthesized homogeneous mixtures of a pyrolitic peridotite (KLB-1) and average mid-oceanic ridge basalt (MORB) were carried out at pressures between 1.5 and 3.0 GPa and temperatures between 1300° and ...
PHASE RELATION AND PHYSICAL PROPERTIES OF AN AL-DEPLETED KOMATIITE TO 23 GPA

Nishihara Y.; Takahashi E. (2001)

Knowledge of the mineralogical constituents of the Earth's mantle depends heavily on high-P experiments of pyrolite composition. In order to understand the planetary interior better, phase relations and mineral physics ...
SOLUBILITIES OF NITROGEN AND NOBLE GASES IN SILICATE MELTS UNDER VARIOUS OXYGEN FUGACITIES: IMPLICATIONS FOR THE ORIGIN AND DEGASSING HISTORY OF NITROGEN AND NOBLE GASES IN THE EARTH

Miyazaki A.; Hiyagon H.; Sugiura N.; Hirose K.; Takahashi E. (2004)

Solubility experiments for nitrogen and noble gases (Ar and Ne) in silicate melts were conducted using two experimental configurations: one was conducted at 1 atmospheric pressure, T =1300°C and oxygen fugacity (fO2) of ...
SOLUBILITY OF NEON, ARGON, KRYPTON, AND XENON IN BINARY AND TERNARY SILICATE SYSTEMS: A NEW VIEW ON NOBLE GAS SOLUBILITY - NMR, RAMAN, AND INFRARED SPECTROSCOPY

Shibata T.; Takahashi E.; Matsuda J.I. (1998)

We determined solubility of Ne, Ar, Kr, and Xe in binary silicate melts (Na2O-SiO2 and MgO-SiO2) and ternary silicate melts (Na2O-CaO-SiO2 and CaO-MgO-SiO2) at total pressures of 1.10-1.99 kbars and temperatures of ...
THERMAL EQUATION OF STATE OF OMPHACITE

Nishihara Yu.; Takahashi E.; Matsukage K.; Kikegawa T. (2003)

In-situ synchrotron X-ray diffraction experiments were conducted using the MAX-III multianvil press of KEK on an omphacite (Di63JD37), for which Di = Ca(Mg,Fe)Si206 and Jd = NaAlSi206 Pressure-volume-temperature data were ...
