Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”
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.

Ore-Forming Biogenic Factor in the Formation of Sandstone-Type Uranium Deposits
Abstract—The geological environment of ore formation in sandstone-type uranium deposits is considered in light of modern geomicrobiological and ecological (environmental) mineralogical data related to solving environmental bioremediation problems (purification of the near-surface environment via bacterial fixation of radionuclides).
