Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate [PDF]

open access: yesAdvanced Science
Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought to be dominated by thermodynamic conditions, yet its intrinsic deformation behavior remains elusive ...

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical 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.
