9315937 Chan 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.

9315937陈皮将对元古界大棉木组进行沉积学分析，包括相和盆地分析、尝试对比和详细的潮汐韵律研究。这些韵律体是迄今记录在案的最古老的韵律体，为研究古季节、月球周期、月球衰退率以及古地球周期和古地球周期提供了机会，将潮汐环境和地月动力学的知识延伸到地球历史上数亿年前。
