    The Medicine Hat Block and the Early Paleoproterozoic Assembly of Western Laurentia by Jennifer N. Gifford, Shawn J. Malone, Paul A. Mueller

    Published 2020-07-01
    “…The accretion of the Wyoming, Hearne, and Superior Provinces to form the Archean core of western Laurentia occurred rapidly in the Paleoproterozoic. Missing from Hoffman’s (1988) original rapid aggregation model was the Medicine Hat block (MHB). …”

    Geobiology of the late Paleoproterozoic Duck Creek Formation, Western Australia by Wilson, Jonathan P., Fischer, Woodward W., Johnston, David T., Knoll, Andrew H., Grotzinger, John P., Walter, Malcolm R., McNaughton, Neal J., Simon, Mel, Abelson, John, Schrag, Daniel P., Allwood, Abigail, Andres, Miriam, Gammon, Crystal, Garvin, Jessica, Rashby, Sky, Schweizer, Maia, Summons, Roger E, Watters, Wesley A.

    Published 2018
    “…The ca. 1.8 Ga Duck Creek Formation, Western Australia, preserves 1000 m of carbonates and minor iron formation that accumulated along a late Paleoproterozoic ocean margin. Two upward-deepening stratigraphic packages are preserved, each characterized by peritidal precipitates at the base and iron formation and carbonate turbidites in its upper part. …”

    Geochemistry and geodynamic setting of Paleoproterozoic granites of Lesser Garhwal Himalaya, India by Sumit Mishra, Vinod K. Singh, Alexander I. Slabunov, H. C. Nainwal, Pradip K. Singh, Neeraj Chaudhary, D. C. Nainwal

    Published 2019-07-01
    “…The granite and gneisses rocks are well exposed around Toneta, Tilwara and Chirbatiyakhal region in the Lesser Garhwal Himalaya have less studied which consider as Paleoproterozoic age. The granites from Toneta area are classified as K-rich peraluminous granite with low Na2O varies from 0.85 to 2.4 wt.% and high K2O content varies from 5.0 to 6.9 wt.%. …”

    Phylotranscriptomics unveil a Paleoproterozoic-Mesoproterozoic origin and deep relationships of the Viridiplantae by Zhiping Yang, Xiaoya Ma, Qiuping Wang, Xiaolin Tian, Jingyan Sun, Zhenhua Zhang, Shuhai Xiao, Olivier De Clerck, Frederik Leliaert, Bojian Zhong

    Published 2023-09-01
    “…Molecular dating analyses suggest that crown-group green plants and crown-group Prasinodermophyta date back to the Paleoproterozoic-Mesoproterozoic. Our study establishes a plausible link between oxygen levels in the Paleoproterozoic-Mesoproterozoic and the origin of Viridiplantae.…”
