Late Precambrian U-Pb titanite age for peak regional metamorphism and deformation (Knoydartian orogeny) in the western Moine, Scotland [PDF]
, 2003 There has been controversy over the number and timing of orogenies in the Precambrian Moine block in the Scottish Caledonides since the earliest radiometric dating in the 1960s. This work challenges a recent hypothesis, that this sector of the Laurentian

Chapter 60 Evidence for late Neoproterozoic glaciation in the central Scandinavian Caledonides
, 2011 The Langmarkberg Formation (Fm). rests on either the Neoproterozoic rift-related Risback Group or Palaeoproterozoic basement in central Scandinavia. It is always succeeded in stratigraphy by the marine Gardsjon Fm. The Langmarkberg Fm.

Mo isotopic composition of the mid-Neoproterozoic ocean: an iron formation perspective [PDF]
, 2013 The Neoproterozoic was a major turning point in Earth's surficial history, recording several widespread glaciations, the first appearance of complex metazoan life, and a major increase in atmospheric oxygen.

Biological feedbacks as cause and demise of the Neoproterozoic icehouse: astrobiological prospects for faster evolution and importance of cold conditions. [PDF]
PLoS ONE, 2007 Several severe glaciations occurred during the Neoproterozoic eon, and especially near its end in the Cryogenian period (630-850 Ma). While the glacial periods themselves were probably related to the continental positions being appropriate for glaciation,

Questioning the biogenicity of Neoproterozoic superheavy pyrite by SIMS
American Mineralogist, 2018 The Neoproterozoic sulfur isotope (δ34S) record is characterized by anomalously high δ34Spyrite values. Many δ34Spyrite values are higher than the contemporaneous δ34Ssulfate (i.e., δ34Spyrite > δ34Ssulfate), showing reversed fractionation.
