... of Kyushu, Japan, in 1934–1935 ( Tanakadate, 1935 ). A large part of the estimated >40 km 3 of pumiceous rhyolite tephra erupted during caldera formation was probably deposited far beyond the study area, but dispersal mechanisms are not well understood. Pumice clasts can be considered in terms...

... and can be traced from northern Kyushu into eastern Korea and China. The SW Japan batholith is thought to represent Andean-style magmatism that occurred when SW Japan was adjacent to China and Korea ( Nakajima, 1996 ). A subordinate episode of felsic volcano-plutonic activity occurred between 42 and 30 Ma...

We have developed a new procedure for the estimation of magma generation conditions and the MPTs by examining ultramafic intrusive rocks in the mantle section of an ~500 Ma arc ophiolite, the Hayachine-Miyamori ophiolite, northern Japan ( Ozawa et al. 2015 ). We argue for a slab...
