Flash Melting Amorphous Ice
Marcel Drabbels, Ulrich Lorenz, Constantin Richard Krüger, Nathan Junior Mowry, Gabriele Bongiovanni
Water can be vitrified if it is cooled at high rates, which makes it possible to outrun crystallization in so-called no man’s land, a range of deeply supercooled temperatures where water crystallizes rapidly. Here, we study the reverse process in pure wate ...
2024Transition from Vertical to Lateral Diking at the Neutral Buoyancy Line
Brice Tanguy Alphonse Lecampion, Andreas Möri, Dmitriy Garagash
Buoyant hydraulic fractures (HF) are a viable approach to model propagating magmatic intrusions in the lithosphere. Solutions for fully planar three-dimensional (3D) HF suggest the existence of a family of solutions as a function of fluid and solid propert ...
2023Magmatic Intrusions From a Hydraulic Fracture Modeling Perspective
Brice Tanguy Alphonse Lecampion, Andreas Möri
The emplacement of magmatic intrusions in the earth’s crust has been investigated for decades. The driving mechanism is the density difference between the fluid and the rock. In the absence of heterogeneities, this difference creates a constant buoyancy fo ...
2023Enrichment of immobile elements in synmagmatic fractures
Alexandra Roma Larisa Kushnir, Michael Heap
Useful minerals containing rare Earth elements (REE) and metals are sourced from magma bodies, but exactly how these elements initially leave the magma is not well known. Here we present textural and chemical analyses of mineral-filled fracture bands withi ...
2022Taking 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 ...
