COLLABORATIVE RESEARCH: Tidal Ryhthmites in the Proterozoic Big Cottonwood Formation, Central Utah: Sedimentology, Sequence Stratigraphy, and Astrophysical Implications

9315985 Kvale pi将对元古代大棉杨组进行沉积学分析，包括相和盆地分析，尝试对比，以及潮汐韵律岩的详细研究。节律虫是迄今为止有记载的最古老的节律虫，它为研究古季节性、月球周期、月球衰退率、古潮汐和古自转周期提供了机会，将潮汐设置和地月动力学的知识扩展到地球历史的数亿年。

9315985 Kvale PIs will conduct sedimentological analyses of the Proterozoic Big Cottonwood Formation, including facies and basin analysis, attempted correlation, and detailed studies of tidal rhythmites. The rhythmites are the oldest yet documented and offer an opportunity to study paleoseasonality, lunar cycles, lunar recession rates, and paleotidal and paleorotational periods, extending knowledge of tidal settings and earth-moon dynamics several hundred million years farther into Earth history.
