Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Geophysical Monograph Series, Page 417-434., 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.

Sulfur Isotope Constraints on the Petrogenesis of the Kimberley Kimberlites
Geochemistry, Geophysics, Geosystems, 2021 Cretaceous kimberlites in southern Africa have been suggested to host deeply subducted material in their mantle sources based on radiogenic isotope systematics. However, potential subducted material contributions to the volatile budget, including sulfur,

Геодинамика и тектонофизика, 2022 Petrophysical, tectonophysical and paleomagnetic studies were done on the field of diamonds from the Komsomolskaya kimberlite pipe to interpret the observed gravimagnetic field. As a result of studying the structural-material complexes (SMC) of the field,

Kimberlite ascent and eruption [PDF]
Nature, 2007 Wilson and Head model kimberlite ascent and eruption by considering the propagation of a volatile-rich dyke. Wilson and Head's model has features in common with Sparks et al., but it is inconsistent with geological observations and constraints on volatile solubility. Here we show that this may be due to erroneous physical assumptions.
