Ignimbrite flare-up in Late Cretaceous–Paleocene Japan empowered by hot mantle inflow

Progress in Earth and Planetary Science
The contribution of subduction parameters, mantle flow, and magmatic systems to the triggering of ignimbrite flare-ups is poorly understood. A re-examination of spatiotemporal variations in igneous activity and Sr–Nd isotopic compositions through ...

Experimental aqueous fluidization of ignimbrite

, 2001
International audienceExperiments were carried out on the aqueous¯uidization behaviour of ignimbrite and the associated formation of¯uidescape pipes. The starting material was an ignimbrite that had been saturated with water under vacuum until 80^15% of ...

A flow-foliated ignimbrite related to the Aland rapakivi granite in SW Finland

, 1996
A flow-foliated felsic ignimbrite constitutes the uppermost lithological unit of the 1.58 Gyr anorogenic magmatic rocks in SW Finland. The ignimbrite is derived from an explosive eruption of hot (approximate to 950 degrees C) phenocryst-bearing A-type ...

Paleomagnetic study of the 30 ka Aira caldera-forming eruption and 60–45 ka Iwato pyroclastic flow deposits, southern Kyushu, Japan

Earth, Planets and Space
To constrain the age and duration of large-scale caldera-forming eruptions, we measured paleomagnetic directions of pyroclastic deposits from the 30 ka Aira caldera eruption sequence, and the 60–45 ka Iwato pyroclastic flow deposits around Aira caldera ...
