Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”
Geophysical Monograph Series, Page 449-486., 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.

Evaluating Extraction of Magnesium and Lithium Compounds from Seawater Using Byproducts of Demonstration-Scale Bipolar Membrane Electrodialysis. [PDF]
ChemSusChemIntegrating multiple seawater‐based processes could improve efficiency and reduce process costs. Here, we assess combining mineral extraction with a demonstration‐scale bipolar membrane electrodialysis (BPMED) unit. Acid and base streams from BPMED are used for lithium and magnesium recovery from seawater, presenting a sustainable method for marine ...
