Adaptive modeling of methane hydrates
Procedia Computer Science, 2010 AbstractWe consider a computational model for the evolution of methane hydrates in subsurface. Methane hydrates, an ice-like compound abundant in subsea sediments and unstable in standard conditions, are an environmental hazard and simultaneously an energy source. Our multiphysics model includes multiphase multicomponent mass conservation equations and

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Transformations in methane hydrates [PDF]
Proceedings of the National Academy of Sciences, 2000 Detailed study of pure methane hydrate in a diamond cell within situoptical, Raman, and x-ray microprobe techniques reveals two previously unknown structures, structure II and structure H, at high pressures. The structure II methane hydrate at 250 MPa has a cubic unit cell ofa= 17.158(2) Å and volumeV= 5051.3(13) Å3; structure H at 600 MPa has a ...
