#3. From Committees

(1) Committee for Diversity Management and Talent Pool

Childcare support during JpGU2023 will be provided in the same manner
as last year. Please refer to last year’s guidelines for reference.

【Call for donations for childcare support】
While the JpGU Committee for Diversity Management and Talent Pool
provided support for childcare fees outside of regular/daily
childcare-use at the last year’s JpGU Meeting, we plan to resume our
support in providing an on-site childcare room at the JpGU 2023, as
we did before the COVID-19 pandemic. However, we have the significant
budget shortfall to do so and we need your financial support.
For your donation to be used for a childcare support, please make a
designated donation by filling out the following form.

Form – Designating donation for a specific purpose
(please fill in after payment from the membership page)

Details are available at the “Request for Donations” page below.

#4. Information from PEPS

(1) Call for Papers : SPEPS
The submission for a new SPEPS (Special call for excellent papers
on hot topics) series has been opened.
“Geophysical Properties and Transport Processes in the Deep Crust
and Mantle”
(Submission deadline: 30 June 2023)
For more information, please check the SPEPS website at:

(2) Featured Articles
We will introduce the featured articles selected by the editor-in-chief
from the papers published in the past.

@Tomoaki Kubo et al.
Back-transformation processes in high-pressure minerals: implications
for planetary collisions and diamond transportation from the deep
This paper reports back-transformation experiments in ringwoodite,
bridgmanite, and lingunite by time resolving in situ X-ray observation
method. These three high pressure phases show different back
transformation mechanisms. Ringwoodite (Mg2SiO4) back-transformed
to olivine by grain-boundary nucleation and growth mechanism, whereas
bridgmanite (MgSiO3) and lingunite (NaAlSi3O8) but first become
amorphous with increasing temperatures before formation of low
pressure phases.

@ Kazuhiko Ishii et al.
A possible mechanism for spontaneous cyclic back-arc spreading.
By constructing a two-dimensional box-type thermal convection model,
the paper showed a possibility that periodic back-arc expansion such
as that seen in the Tonga-Kermadec arc and the Calabria arc is caused
by the interaction between the slab and the upper and lower mantle
