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，由SEPM提供会议注册和后勤的主要管理工作。在本提案中，pi试图解决以下六个关键的核心科学问题，这些问题具有重要的智力价值：1)地质记录中不同类型的古土壤的保存潜力是什么？2)古土壤记录的时间和事件保存的保真度如何？3)在层序地层学中，古土壤“适合”在哪里？4)目前由野外形态和地球化学指标组成的古气候“工具箱”是否已经达到了可能达到的高度？5)标准的美国农业部土壤物理和化学表征技术在多大程度上可以用于建立古土壤的胶体特性？6)古土壤研究是否在美国国家研究委员会-国家科学基金会“关键地带”得到充分代表？

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"?
