Palaeomagnetism of climatically sensitive sedimentary rock types, such as glacial deposits and evaporites, can test the uniformitarianism of ancient geomagnetic fields and palaeoclimate zones.

Oxygen levels in the atmosphere during the mid-Proterozoic—about 1.4 billion years ago—were higher than previously thought, according to an international team of researchers who looked at oxygen ...

Determining the location and orientation of the Archean-Proterozoic suture zone between these provinces is also important because it may influence subsequent patterns of sedimentation, deformation, ...

Advanced tools and expanded fossil datasets have painted a clearer picture of the eukaryotic diversity of the Proterozoic eon, which has been hard to quantify. The findings show that Earth's severe ...

The Proterozoic is a Precambrian eon of geologic time extending from about 2.5 billion to 541 million years ago, bounded by the Archean–Proterozoic and Proterozoic–Phanerozoic transitions. It is ...
