| 内容記述 | The Quaternary Kurobegawa Granite, central Japan, is not only the youngest known granitic pluton exposed on the Earth's surface, it is one of few localities where both Quaternary volcanics and related plutons are well exposed. Here, we present new zircon U-Pb ages together with whole rock and mineral geochemical data, revealing that the Kurobegawa Granite is a resurgent pluton that was emplaced following the caldera-forming eruption of the Jiigatake Volcanics at 1.55 +/- 0.09 Ma. Following the eruption, the remnant magma chamber progressively cooled forming the voluminous Kurobegawa pluton in the upper crust (similar to 6 km depth) until similar to 0.7 Ma when resurgence caused rapid uplift and erosion in the region. This is the first study to document the detailed spatiotemporal evolution of resurgent pluton for a Quaternary caldera system. Our new findings may contribute significantly to understanding the fate of active caldera systems that can produce supereruptions. | |||||||||||||||||||||||||
