Message from the program leader
Tetsuo IRIFUNE
Professor and Director of Geodynamics Research Center,
Ehime University"Global Center of Excellence(COE) Program" aims at
forming world-class researchhubs in Japanese Universities
with strong financial support by
the Japanese government. We,a group of researchers in Ehime
University(Geodynamics
Research Center, GRC, andGeophysics
divisionatGraduate School of Sciences),
together with those of alliedlaboratories in University ofTokyo, Japan Synchrotron
Research Institute (JASRI), and Stony Brook University (SBU)
submitted a proposal entitled "Center for Advanced Experimental
and Theoretical Deep Earth Mineralogy" for this highly
cutting-throat competition.
This proposal has been selected as one of 3 successful programsin Earth science field, in which we will advance cutting-edge
sciences in deep Earth mineralogy, focusing on the topics
represented by the keywords "lower mantle mineralogy", "corematerials", and "deep Earth water". We will also conduct
interdisciplinary studies, such as solid-state physics, inorganic
chemistry, and materials science, utilizing the rich resources ofhigh-pressure and other facilities at GRC. Moreover, newtechnologies in experimental and computational sciences relevantto these studies will also be developed in this program.
For instance, we will develop techniques to produce pressuresof Mbar regime in multianvil apparatus using sintered diamondanvils, while the P, T conditions for precise determination ofsound velocities, developed by the program member of SBU, will
be extended to those of the lower mantle. Application of the
newly produced nano-polycrystalline diamond (NPD or
HIME-dia) to various types of high-pressure apparatus will also
be pursued in order to realize higher pressure and temperature
generation in larger sample volumes as compared to thoseavailable in conventional high-pressure apparatus. We will also
focus on the development of techniques relevant to theapplications of "quantum-beams" in deep Earth mineralogy,
particularly those of synchrotron and neutron available atSPring-8 and at J-PARC, respectively, in collaboration with theprogram members of JASRI and Univ. Tokyo.
The new experimental data based on these techniques will be
examined with first-principles calculations by the numericalsimulation group of GRC, while the predictions based on the latterstudies will in turn guide the experimental exploration of the
behavior of Earth's materials at very high pressure andtemperature. Moreover, these data are used for realistic computer
simulations of dynamics of the Earth, as well as for understanding
the seismologically derived structures of the Earth's deep interior

in the numerical simulation group.
Another important aim of our program is to train young
scientists in deep Earth mineralogy and related fields. We will
accept 15-20 PhD students and 20-30 post-doctoral fellows,
including those from overseas, in experimental and theoretical
deep Earth mineralogy, particularly in the fields of high-pressuremineral physics, quantum-beam applications, and first-principle
computations during the period of the program. To this end, we
will open a special course with exemption of the tuition andproviding scholarships as well as significant research funds, in the
Graduate School of Science of Ehime Univ., and annually invite
up to 4 highly motivated foreign and Japanese PhD students at
GRC for this program. We will have special training programsfor these young scientists, including internships in the members'
and other domestic and overseas laboratories, which have strong
relations with GRC, such as having official agreement on thecollaboration in research and education (i.e. GSECARS, Univ.
Chicago; Bayerisches Geoinstitut, Univ. Bayreuth; Mineral
Physics Institute, SUB; Laboratoire de Geologie, CNRS-ENS;
Institute of Earth Sciences, National Chen Kung Univ.; RSES,
Australian National University).
In addition to the above research and training activities, an
important goal of our Global COE program is to form aninternational research/education network of deep Earthmineralogy in Asia region, in order to enhance international
collaborations and exchange of people in this field. Althoughscientific and technological contributions from the Asian countries
to the advancement in deep Earth mineralogy have been quite
significant, we do not have any effective network platforms formutual interactions among the researchers and students in thesecountries, such as those established in USA (COMPRES) andEurope (Crust to Core, c2c), in spite of the geographically close
relations. Thus we plan to form a network (The Asian Network in
Deep Earth Mineralogy, TANDEM) to combine unique techniques
and facilities in individual laboratories in Asian region to develop
new frontiers in deep Earth mineralogy as well as in training
young scientists in this and related research fields.
Matsuyama, where GRC and the headquarters of the global
COE program are located, is the largest city in southern mainisland of Shikoku in Japan. The famous hot spa, Dogo Onsen,
and the beautiful Matsuyama castle on the hill are within thewalking distances from the GRC office building, and you may
also enjoy scenic views of hundreds of islands floating on thecalm Seto inland sea near the city. This area is known as themodest climate throughout a year (though a little bit warm insummer), rich nature, low living costs, and is an ideal place to live
in. We heartily welcome and invite those who wish to explore thesecrets of the Earth's deep interior to our global COE program on
Deep Earth Mineralogy. Bon voyage to the center of the Earth!

Hot Researches by Young Scientists

Kyoko N. MATSUKAGE(Global COE Research Fellow)

My research interests relate to thegeochemical effects of fluid (melt) associated with recycling of crustal and mantle
materials in interior of our planet. One ofresent subjects of my study is the geochemical evolution of the continental mantle. I
research the mantle-derived peridotites
obtained as xenoliths of alkali basalt from
Cameroon volcanic line (CVL), and of
kimberlite from Lesotho and Botswana in
African craton. These xenoliths give us
direct information about the feature andevolution of chemical, petrological andmineralogical variations of the upper mantle

High-temperature ultrasonicmeasurement in multi-anvil
apparatus under the melting
temperatures of mantle materials
Yoshio KONO
(Global COE Postdoctoral Fellow)

Measurement of the elastic wave velocitiesof partially or completely molten mantle
materials is important to understand thenature and dynamics of the Earth's upper
mantle, such as those relevant to subduction
volcanism,
lithosphere-asthenosphereboundary and/or possible melt layer above
the 410 km discontinuity. Some attempts tomeasure elastic wave velocities of silicate
melts have been made at high temperatures
and atmospheric pressure (e.g. Ai andLange, 2008), but the corresponding
measurement under the upper mantle

beneath volcanoes.
The CVL is a 1,600-km volcanic chain
sitting on the continental margin of West
Africa. It is well known as the former triple
junction, which is made by an upwelling
deep mantle plume that controlled theseparation of Africa from South America
and opening the Atlantic Ocean at ~120 Ma.
The CVL is erupting on the failed rift arm of
the triple junction. The heterogeneity of
texture and chemistry of this area can be
explained by process of partial melting andsubsequent melt extraction in sallow mantle
at depth of 30-80 km. The estimated degreeof melting (~30 %) of residual peridotite andthe chemical feature of the constituent
minerals, that was depleted in incompatible
element (SiO2, Al2O3, CaO) with respect tocompatible elements (MgO, Cr2O3), indicatethat the partial melting occurred at almost
dry condition. Garnet peridotites from morethan 100 km in depth at Lesotho and
Botswana areas have quite different withchemistry from that of CVL. The peridotitesof these areas characterized the extremely
high amount of orthopyroxene (= highamount of SiO2) with high MgO content.
These high-Si and -Mg rocks could not
explained as residue of dry partial melting(see Fig. 1), but may be residues of partial
melting at H2O-saturated condition at higher

pressure at depth of 200-300 km.
The results suggest that the Earth's mantle
is very heterogeneous in water content. The
measurement of mineral-liquid/fluid distribution coefficients for elements in major
phases is very important to understand thechemical evolution of the Earth's interior.
Because the distribution coefficients ofmineral-dry melt are expected to be different to that of mineral-wet fluid. My researchat the GRC will focus on geochemical
effects in both wet and dry conditions,texture of rocks and migration mechanismof fluid and melt at deep Earth.

pressure conditions has not yet reported todate, because of the limitation in temperature conditions of elastic wave velocity
measurement at high pressures (Fig. 1). We
therefore need to develop the experimental
technique for elastic wave velocity
measurement at high-pressures and attemperatures greater than the melting
temperatures of mantle materials (higher
than 1400 ˚C) to address the above issues.
Here I report some preliminary results ofultrasonic measurement at temperatures to1700 ˚C at high pressures. Graphite wasused as the heater instead of platinum usedin our previous studies, and zirconia wasused as thermal insulator. I also adopted
highly sintered zirconia as the buffer rod fortransmitting ultrasonic waves to the sample.
The ultrasonic measurement shows clear
elastic wave signals reflected at both ends ofa sample up to 1700 ˚C, which is higher thanthe melting temperatures of most hydrous
silicates and of some anhydrous silicates.
Then ultrasonic measurements were carriedout for MORB sample to the melting
temperature at ~5 GPa. I successfully
obtained P-wave signals reflected at bothends of the MORB sample up to 1600 ˚C,
but S-wave signals disappeared above~1400 ˚C, which would be attributed tostrong attenuation of S-wave by (partial)

melting of MORB. P-wave travel time
becomes significantly long above 1400 ˚C
due to the melting of MORB. SEM observation of the run product shows that melt
was enclosed by BN capsule, but that melt
infiltrates into the zirconia buffer rod.
Further improvement for enclosing melt
should enable us to determined elastic wave
velocities of molten mantle materials at
simultaneous high-pressures and hightemperatures comparable to the Earth's
upper mantle.

TANDEM Laboratories (2009 January)

TANDEM (The Asian Network in Deep Earth Mineralogy) is
an international network in Asia region for the advancement ofexperimental and computational studies on physical properties,
structures, dynamics, and evolution of the Earth's deep interior.
TANDEM members combine unique techniques and facilities inindividual laboratories to develop new frontiers in deep Earthmineralogy as well as in training young scientists inhigh-pressure research. TANDEM is coordinated byGeodynamics Research Center (GRC), Ehime University, withfinancial support by the Global COE program "Center for
Advanced Experimental and Theoretical Deep EarthMineralogy" funded by MEXT, Japan. We will organize the first
TANDEM symposium to discuss the future directions of thisnetwork and to share the information about the research andeducation programs in individual laboratories.

Laboratory for Mineral and Rock Physics in the GPMR, China University of Geosciences at Wuhan
China University of Geosciences is a national key university
founded in 1952 in China. It has two campuses: the Wuhan
campus and the Beijing campus. It is more than just a university
specialized in geosciences. The Wuhan campus has 22 schools ofsciences, engineering, literature, economics, law, education andphilosophy. It offers 37 Phd programs, 131 Mater degree
programs and 62 Bachelor's degree programs. Its faculty consistsof ~350 professors and ~580 associate professors, including 9
current members of the Chinese Academy of Sciences. Its current
student enrollments are over 44,000.
The State Key Laboratory of Geological Processes and Mineral
Resources (GPMR) was established at the China University ofGeosciences and sponsored by the Chinese Ministry of Educationand the Ministry of Land and Resources. Its original main
purpose was to provide a platform for conducting
inter-disciplinary geoscience research on the lithosphere
evolution and mineralization processes, spatial-temporal
distribution of mineral resources, and mineral exploration andmineral resources assessment. Its current research scope has
expanded into deep Earth dynamics, environmental protection and geological hazard control. The GPMR consists of five researchdivisions and led by six members of the Chinese Academy of Sciences. There are 42 full-time professors and researchers in the GPMR.
The laboratory for mineral and rock physics is part of the first division of the GPMR (Division of Composition, Structure and Evolutionof the Lithosphere). It is also a relatively new laboratory/research group in the GPMR. Professor Zhenmin Jin is the head of thelaboratory for mineral and rock physics. There are currently 7 faculty, 2 postdocs, 3 PhD students and 6 Master students in the group.
The laboratory currently houses a 1-atmosphere pressure gas media deformation apparatus and one 5 GPa piston cylinder apparatus. Two
new apparatus (a 28GPa Walker's-type multianvil and a 5 GPa Griggs-type deformation apparatus) will join the apparatus family by theend of 2009. In addition to those high P/T apparatus, the GPMR is also equipped with a broad spectrum of analytical instruments(JXA-8100 electron probe, Quanta200 SEM (with an HKL EBSD system), RM1000 Laser Raman, POEMS III ICP-MS, CM12 STEM,
Agilent7500a Laser Ablation System, etc). The GPMR provides
financial support for short- and long-term external visiting
scientists to conduct collaborative research. The laboratory formineral and rock physics is currently collaborating actively withseveral international research laboratories in the geosciences field
including Prof. Harry Green's laboratory at University of California
at Riverside (USA) and Prof. Yingwei Fei's laboratory at Carnegie
Institution of Washington (USA). Our research interests are but notlimited to the experimental deformation of rocks and minerals athigh temperature and pressure, rheology of the crust and mantle,
earthquake physics and ultrahigh pressure metamorphism. We lookforward to establishing stable and substantial collaborations withany interested individual or institution of the TANDEM on
high-pressure geoscience researches and training of young
scientists and graduate students.
