Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 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.

Numerical Modeling on Hydraulic Fracturing in Coal‐Rock Mass for Enhancing Gas Drainage [PDF]
Advances in Civil Engineering, 2018 The mechanism of how hydraulic fracturing influences gas drainage in coal‐rock mass is still not clear due to its complex mechanism. In this work, statistical distributions are firstly introduced to describe heterogeneity of coal‐rock mass; a novel simultaneously coupled mathematical model, which can describe the fully coupled process including seepage‐
