Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 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.

Two‐Stage Dolomite Formation in Carbonate Platforms Revealed by Carbonate Clumped Isotope Thermometry

open access: yesGeophysical Research Letters
The “dolomite problem” refers to the scarcity of dolomite in Cenozoic marine environments compared with its abundance in earlier strata. This discrepancy has been attributed to changes in marine environments or to insufficient thermal maturity required ...
