Transition 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 ...
2023Hot rocks: Constraining the thermal conditions of the Mistastin Lake impact melt deposits using zircon grain microstructures
The production of superheated melt during hypervelocity impact events has been proposed to be a common occurrence on terrestrial planetary bodies. Recent direct evidence of superheated impact melt temperatures exceeding > 2370 degrees C from the Kamestasti ...
ELSEVIER2022Investigating Magma Ocean Solidification on Earth Through Laser‐Heated Diamond Anvil Cell Experiments
Philippe Gillet, Cécile Hébert, Marco Cantoni, James Badro, Farhang Nabiei, Charles-Edouard Boukaré
We carried out a series of silicate fractional crystallization experiments at lower mantle pressures using the laser-heated diamond anvil cell. Phase relations and the compositional evolution of the cotectic melt and equilibrium solids along the liquid lin ...
2021Fully-coupled 3D modelling of magmatic dike Propagation – finite pulse release from a point source
Brice Tanguy Alphonse Lecampion, Andreas Möri, Haseeb Zia
Magmatic dikes are a naturally occurring type of fluid-driven fractures [1] propagating in the lithosphere driven by buoyancy (more precisely by the difference between the in-situ minimum horizontal stress gradient and the magma weight). Fully-coupled mode ...
2020Transition from a radial to a 3D buoyancy-driven hydraulic fracture
Brice Tanguy Alphonse Lecampion, Andreas Möri
Magmatic dikes are a naturally occurring type of fluid-driven fractures (Rivalta et al. 2015) propagating in the lithosphere due to buoyant forces emerging from the density difference between the host material and the injected fluid (more precisely the dif ...
2020PyFrac: A planar 3D hydraulic fracture simulator
Brice Tanguy Alphonse Lecampion, Haseeb Zia
Fluid driven fractures propagate in the upper earth crust either naturally or in response to engineeredfluid injections. The quantitative prediction of their evolution is critical in order to better understandtheir dynamics as well as to optimize their cre ...
2020Microbial-induced carbonate precipitation applicability with the methane hydrate-bearing layer microbe
Production of methane gas from the methane-hydrate-bearing layer below the deep-ocean floor is expected to be crucial in the future of energy resources worldwide. During the methane gas-production phase from the methane hydrate with the depressurisation me ...
