Melt evolution and crystal cargo uptake at Mount Ruapehu: a magma plumbing system characterized by narrow dikes and sills

Abstract To assess the magma plumbing architecture of Mount Ruapehu, an active stratovolcano in the Taupō Volcanic Zone (New Zealand), we combine whole rock, groundmass and crystal geochemistry of lava samples from the south-west flank, focusing on the Mangawhero (50–15 ka) and W...

Experimental constraints on the differentiation of CM-like planetary embryos

This study investigates the onset of differentiation of hydrous (ice-bearing) planetary embryos in the early Solar System. To do so, we conducted high-pressure (1 GPa) melting experiments on a CM2 chondrite (MCY12002) across a temperature range of 1050-1400°C, with durations vary...

Antecryst acquisition when eruptible and non-eruptible silicic magmas collide in the upper crust, illustrated by the ~ 14 ka Belfond event, Saint Lucia (Lesser Antilles)

Abstract Antecrysts are relic or co-magmatic phenocrysts that are common in volcanic rocks of arc settings. Their occurrence is a foundation of the crystal mush paradigm for crustal magmatism, although the putative mush is rarely erupted. The 13.6 ka Belfond eruption (Saint Lucia...
