The Fuchuan Ophiolite in South China: Evidence for Modern‐Style Plate Tectonics During Rodinia Breakup

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Subduction initiation processes, such as those evidenced in the Izu‐Bonin‐Mariana (IBM) forearc crust are a key feature of modern‐style plate tectonics.

Neoproterozoic Low‐δ18O Zircons Revisited: Implications for Rodinia Configuration

open access: yesGeophysical Research Letters, 2019
Neoproterozoic magmatic rocks and detrital zircons with low‐δ18O values were frequently identified in the Yangtze Block, Madagascar, and India. Here we first report Neoproterozoic low‐δ18O zircons from the central part of the Cathaysia Block in South ...

Neoproterozoic low latitude glaciations: an African perspective [PDF]

open access: yes, 2011
The Neoproterozoic is one of the most enigmatic periods in Earth history. In the juxtaposition of glacial and tropical deposits the sedimentary record provides evidence for extreme climate change. Various models have tried to explain these apparent

Considering a Neoproterozoic Snowball Earth

open access: yesScience, 1999
P. F. Hoffman et al. and N. Christie-Blick et al. discuss Hoffman et al.'s paper that "developed a modified 'snowball Earth' hypothesis (2) to explain the association of Neoproterozoic low-latitude glaciation with the deposition of 'cap carbonate' rocks bearing highly depleted carbon isotopic values (δ13C ≤ −5‰).

Research Progress on Re-Os Isotopes Application in Dating and Paleoenvironmental Interpretation during the Neoproterozoic to Early Cambrian Periods

open access: yesYankuang ceshi, 2016
The Neoproterozoic to Early Cambrian period is a very important era in the history of earth evolution. Research on stratigraphic framework, paleo-oceanography, palaro-atmospheric, and paleoclimatology are focuses of international geosciences.

3D inversion of the Sichuan Basin magnetic anomaly in South China and its geological significance

open access: yesEarth, Planets and Space, 2020
The Sichuan Basin magnetic anomaly is the most striking regional aeromagnetic anomaly in South China. It is characterized by a continuous large-scale linear magnetic anomaly and contains long-wavelength constituents which could still be detected on ...
