Geophysical Monograph Series, Page 305-323., 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.

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Paleolatitude and cause of the Svecokarelian orogeny [PDF]
Bulletin of the Geological Society of Finland, 1974 Paleomagnetic data suggest a paleolatitude of 22°N for the Fennoscandian protocontinent during the Svecokarelian orogeny. This is lower than that of the Canadian shield during the same period.

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]
, 2001 The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

Analysis of a Precambrian resonance-stabilized day length [PDF]
, 2016 During the Precambrian era, Earth's decelerating rotation would have passed a 21-hour period that would have been resonant with the semidiurnal atmospheric thermal tide.

Onshore-offshore patterns in Late PreCambrian and Lower Palaeozoic trace fossils [PDF]
The Paleontological Society Special Publications, 1992 There was a dramatic increase in abundance and diversity of trace fossils in Upper Precambrian and Lower Cambrian shallow water seas. The trace-producing animals rapidly filled all the available niches and in low energy, muddy, environments they evolved winding, meandering and patterned habits. Traces such as Taphrhelminthopsis, Helminthoida, Nereites,
