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

open access: yesGeophysical 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.

Petrogenesis and tectonic affinity of Early Cretaceous potassic diorites in the northern Taihang Mountain, Trans-North China Orogen

open access: yes, 2022
Mesozoic mantle-derived potassic magmatic rocks in the Trans-North China Orogen (TNCO) are important for constraining tectonic evolution. However, potassic intermediate plutons in this orogen are rarely reported in literature, despite the significance of

Reflection of petrologic regularities in the mineralogy of tonalite-granites and diorite inclusions in them: Comparison of granitoid massifs of the Urals and the Alps

open access: yesVestnik MGTU
Orogenic granitoid massifs contain a variety of mafic inclusions (autoliths, xenoliths, mingling dikes). These include predominantly diorite-series inclusions, which visually contrast with the host tonalite-granite associations but have similar mineral ...
