Taking the pulse of volcanic eruptions using plagioclase glomerocrysts
Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy, Pierre Vonlanthen
Crystallization timescales in subvolcanic systems and the consequences of interaction between ascending magmas and gases remain largely unconstrained, as do links between these processes and monitoring signals at restless volcanoes. We apply diffusion chro ...
ELSEVIER2020Weekly to monthly time scale of melt inclusion entrapment prior to eruption recorded by phosphorus distribution in olivine from mid-ocean ridges
Anders Meibom, Stéphane Laurent Escrig, Othmar Müntener, Lukas Baumgartner, Mélina Manzini
Melt inclusions (MIs) hosted in euhedral olivine have been proposed to represent droplets of primary melt, protected from processes occurring near Earth's surface during eruption. The complex zoning of phosphorus (P) in some olivines and the presence of a ...
Geological Soc Amer, Inc2017The structure of the asteroid 4 Vesta as revealed by models of planet-scale collisions
Asteroid 4 Vesta seems to be a major intact protoplanet, with a surface composition similar to that of the HED (howardite-eucrite-diogenite) meteorites(1-4). The southern hemisphere is dominated by a giant impact scar(5), but previous impact models(6-8) ha ...
Nature Publishing Group2013Petrophysical properties of the root zone of sheeted dikes in the ocean crust: A case study from Hole ODP/IODP 1256D, Eastern Equatorial Pacific
ODP (Ocean Drilling Program)/IODP (Integrated Ocean Drilling Program) Site 1256 is located on the Cocos Plate in the Eastern Equatorial Pacific Ocean, in a 15. Ma old oceanic lithosphere formed at the EPR during a period of superfast spreading (> 200 mm/yr ...
