[Article Publication] A paper on the shock experiments of quartz, in which JAMSTEC/Kochi Core Principal Researcher (Visiting Professor at Hiroshima University) Tomioka participated, was published in Journal of Geophysical Research.

Feather Features (FFs) in quartz, consisting of planar fractures (PF) and fine lamellae (FFL), were found to form over a wide pressure range of 2–18 GPa through shock recovery experiments, and they can be classified into at least three types (I–III), suggesting their potential as a shock pressure barometer for quartz-bearing rocks (Published paper url).
