EAGER: A novel Approach to Study Earth's Oldest Environments and Biosphere: Tidal, Shelf, and Deep Ocean Habitats in the >3.7 Ga Isua Greenstone Belt, Greenland

研究地球最古老环境和生物圈的新方法：格陵兰岛3.7 Ga伊苏亚绿岩带的潮汐、陆架和深海栖息地诺拉·诺夫克，格陵兰岛的伊苏亚绿岩带（IGB）包括地球历史上保存最古老的3.7 Ga沉积物。到目前为止，坚定的教条是，所有的IGB岩石都是高度变质的，因此关于地球最古老的古环境和生命起源的信息将被抹去或被严重掩盖，以至于无法得出确切的结论。该项目允许分析表明，IGB构成了地球最深处的宝贵档案。Linda Hinnov新开发的方法允许pi通过分析浅海沉积物的层理特征来揭示这种独特的信息。这些结果将有助于了解3.7亿年前的地月星座，每年的天数，以及可能的季节性。

EAGER: A Novel Approach to Study Earth's Oldest Environments and Biosphere: Tidal, Shelf, and Deep Ocean Habitats in the 3.7 Ga Isua Greenstone Belt, GreenlandNora Noffke, Old Dominion UniversityEAR-1232499The Isua Greenstone Belt (IGB), Greenland, comprises the oldest, 3.7 Ga sediments preserved in Earth history. Until now the firm dogma is that all IGB rocks would be highly metamorphosed and therefore information on Earth's oldest paleoenvironment and the origin of life would be erased or so strongly masked that no firm conclusions can be drawn. This project allows analyses demonstrating the IGB constitutes a valuable archive on Earth's deepest time. Linda Hinnov's newly developed methods allow the PIs to reveal this unique information by analyzing bedding characters in shallow-marine deposits. The results will allow the understanding of the Earth-Moon constellation 3.7 Ga ago, the number of days per year, and possibly seasonality.
