Geophysical Monograph Series, Page 1-26., 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.

Earth system simulations suggest that the Proterozoic ocean was greener but less productive [PDF]
Nature CommunicationsGeological records suggest that marine phytoplankton might have arisen in the Proterozoic while zooplankton remained absent, and marine productivity was not excessively low.

Morphometric convergence between Proterozoic and post-vegetation rivers [PDF]
Nature Communications, 2017 It has been previously assumed that deep river channels could not have developed in the Proterozoic due to lack of vegetation. Here, the authors present remote sensing and outcrop data to show that large scale and deeply channelled river networks did ...

Sequence stratigraphy in Proterozoic successions [PDF]
Geology, 1988 Sedimentological logging and facies mapping have been used to identify depositional sequences bounded by subtle but regionally persistent unconformities in rocks of Proterozoic age in the western United States, South Australia, and northwestern Canada. We conclude from these studies that the sequence stratigraphic approach is of considerable importance

Precambrian tsunamis in the light of the modern data
Известия высших учебных заведений: Геология и разведка, 2023 Background. In the geological history of the Earth, tsunami events attract particular research attention. Such events are assumed to have taken place already since the Precambrian period.
