IN SITU X-RAY DIFFRACTION STUDY OF POST-SPINEL TRANSFORMATION IN A PERIDOTITE MANTLE: IMPLICATION FOR THE 660-KM DISCONTINUITY

Litasov K.; Ohtani E.; Sano A.; Suzuki A.; Funakoshi K. (2005)

We present the phase relations in anhydrous CaO-MgO-FeO-Al2 O3-SiO2-pyrolite to examine the influence of compositional difference between pyrolite and Mg2 SiO4 on the post-spinel phase transformation. It is shown that in ...
IN SITU X-RAY OBSERVATIONS OF PHASE TRANSITIONS IN MGAL2O4 SPINEL TO 40 GPA USING MULTIANVIL APPARATUS WITH SINTERED DIAMOND ANVILS

Irifune T.; Naka H.; Sanehira T.; Inoue T.; Funakoshi K. (2002)

Phase transitions in MgAl2O4 spinel have been studied at pressures 22-38 GPa, and at temperatures up to 1600 °C, using a combination of synchrotron radiation and a multianvil apparatus with sintered diamond anvils. Spinel ...
PHASE TRANSITION OF ZIRCON AT HIGH P-T CONDITIONS

Ono S.; Funakoshi K.; Nakajima Y.; Tange Y.; Katsura T. (2004)

In situ observations of the zircon-reidite transition in ZrSiO4 were carried out using a multianvil high-pressure apparatus and synchrotron radiation. The phase boundary between zircon and reidite was determined to be P ...
RADIOGRAPHIC STUDY ON THE VISCOSITY OF THE FE-FES MELTS AT THE PRESSURE OF 5 TO 7 GPA

Urakawa S.; Terasaki H.; Kato T.; Funakoshi K.; Suzuki A. (2001)

Stokes' viscometry combined with in situ X-ray radiographic observation, using the 6-8 type multi-anvil press and synchrotron radiation, has been applied to the viscosity measurement of the Fe-FeS melt up to pressures of ...
SPINEL-GARNET LHERZOLITE TRANSITION IN THE SYSTEM CAO-MGO-AL2O3-SIO2 REVISITED: AN IN SITU X-RAY STUDY

Walter M.; Katsura T.; Kubo A.; Shinmei T.; Nishikawa O.; Ito E.; Lesher C.; Funakoshi K. (2002)

Large discrepancies are reported for the near-solidus, pressure-temperature location of the spinel to garnet lherzolite univariant curve in the system CaO-MgO-Al2O3-SiO2 (CMAS). Experimental data obtained previously from ...
THERMAL EXPANSION OF MG(OH)2 BRUCITE UNDER HIGH PRESSURE AND PRESSURE DEPENDENCE OF ENTROPY

Fukui H.; Ohtaka O.; Suzuki T.; Funakoshi K. (2003)

An equation of state for Mg(OH)2 brucite under high-pressure and high-temperature conditions has been obtained by measuring temperature dependence of volume up to 600 K at ambient pressure and pressure dependence of volume ...
VISCOSITY OF ALBITE MELT AT HIGH PRESSURE AND HIGH TEMPERATURE

Suzuki A.; Ohtani E.; Funakoshi K.; Terasaki H.; Kubo T. (2002)

The viscosity of albite (NaAlSi3O8) melt was measured at high pressure by the in situ falling-sphere method using a high-resolution X-ray CCD camera and a large-volume multianvil apparatus installed at SPring-8. This system ...
