1. 13:30-13:45
TITLE: Magma plumbing system of Miyakejima volcano, Japan, as seen from ground
deformation, petrology, and geochemistry
AUTHOR: *Yosuke AOKI･Derek J. WELLER･Shuhei SAKATA･Atsushi YASUDA･
Mie ICHIHARA, Nobuo GESI (AIST), Yuji ORIHASHI(Hirosaki Univ.)
and Shoichi ITOH (Kyoto Univ.)　
SUMMARY: We discuss magma plumbing system of Miyakejima volcano from recent ground
deformation measurements and petrological and geochemical insights of products
from previous eruptions.

2. 13:45-14:00
TITLE: Towards understanding of geochemical scale structures for deep earth science
with geoneutrinos
AUTHOR: *Sanshiro ENOMOTO(Physics, Univ. of Washington), Nozomu TAKEUCHI,
Tsuyoshi IIZUKA (EPS, U Tokyo), Kenta UEKI(JAMSTEC), Kazuki MINAMI･
Satoru HARAGUHI and Hiroyuki TANAKA
SUMMARY: After brief introduction to geoneutrino observation at Kamioka,
we will discuss a viewpoint of "geochemistry scales", which emerged in
the investigation of global geophysics with neutrinos.

3. 14:00-14:15
TITLE: Quantitative evaluation of the geochemical correlation length within
the single granitic body
AUTHOR: Kazuki MINAMI, *Kenta UEKI(JAMSTEC), Akimichi TAKETA,
Tsuyoshi IIZUKA (EPS, U Tokyo), Sanshiro ENOMOTO(Physics, Univ. of Washington),
Nozomu TAKEUCHI and Hiroyuki TANAKA
SUMMARY: We present a result of the statistical analysis of the spatial correlation
length of the chemical composition of granite in a single body.
