The correlation between Neoproterozoic tectonics, paleoenvironment and early life are
crucial for understanding the evolution of the Earth's habitability. The Yangtze Block …

In order to explore Cryogenian seawater chemistry and its underlying controls, we present
an integrated study of iron speciation, major and trace elements, and carbon isotopes of Mn …

Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

The Cryogenian Sturtian and Marinoan Snowball Earth glaciations bracket a nonglacial
interval during which Demosponge and green-algal biomarkers first appear. To understand …

Constructing an accurate timeline is critical for reconstructing the Earth systems through
critical transitions in climate, geochemistry, and life. Existing dates constrain synchronous …

Iron is a remarkable element in its relatively high abundance for its mass and its sensitivity to
(and control of) redox on a planetary scale over geologic time. Numerous volumes have …

Abstract The Neoproterozoic Datangpo Formation of the Nanhua Basin in South China
records interglacial sedimentation between the~ 720–660-Ma Sturtian and~ 654–635-Ma …

The appearance and radiation of animals are commonly attributed to Neoproterozoic
oceanic oxygenation, yet independent geochemical evidence for such an event remains …

The body fossil and biomarker records hint at an increase in biotic complexity between the
two Cryogenian Snowball Earth episodes (ca. 661 million to≤ 650 million years ago) …

Abstract The Cryogenian Period comprised two episodes of global glaciation (Sturtian and
Marinoan glaciations) separated by a non-glacial interval, which was characterized by early …
