Joint SEPM-NSF Workshop: Paleosols and Surface Soil System Analogs; September 21-25, 2010 at Petrified Forest National Park (PFNP), Arizona

本次会议将由SEPM和NSF共同主办，SEPM提供会议注册和后勤的主要管理。 在这一建议中，PI试图解决这六个关键的核心科学问题，这些问题具有重要的知识价值：1）地质记录中不同类型的古土壤的保存潜力是什么？2)古土壤中记录的时间和事件保存的真实性如何？3)古土壤在层序地层学中的位置？4)目前的古气候“工具箱”包括现场形态和地球化学代理，因为它可能成为先进的？5)标准的USDA土壤物理和化学表征技术在多大程度上可以用于确定古土壤的胶体性质？6)古土壤研究在美国国家研究委员会-国家科学基金会的“临界区”中是否得到了充分的代表？

This conference will be co-sponsored by SEPM and NSF, with primary administration of the meeting registration and logistics provided by SEPM. In this proposal PIs seek to address these six key central scientific questions, which have significant intellectual merit:1) What is the preservation potential of different types of paleosols in the geologic record?2) What is the fidelity of time and event preservation recorded in paleosols?3) Where do paleosols "fit" in sequence-stratigraphy?4) Is the current paleoclimate "toolkit" comprised of field morphological and geochemical proxies as advanced as it can likely become?5) To what extent can standard USDA soil physical and chemical characterization techniques be used for establishing colloidal properties of paleosols?6) Is paleosol research adequately represented within the US National Research Council-National Science Foundation "Critical Zone"?
