确定沉积地质学古生物学的重大挑战召集人：伊莎贝尔蒙塔涅斯（加州大学戴维斯分校）查尔斯马歇尔（加州大学伯克利分校）摘要地球？地球的表层地壳蕴藏着（1）矿物、碳氢化合物和水资源，（2）过去气候变化的全方位记录，（3）在过去各种条件下生态系统变化幅度和速度的天然实验室，（4）生命进化史的档案，包括整个地球的生物多样性和进化创新？历史，特别是在环境条件迅速变化的时期，以及（5）导致或应对自然灾害（如地震，洪水，火山爆发）的过程的记录。对这些和相关问题的科学调查主要是沉积地质学家、地球化学家和古生物学家的职权范围，他们的合作越来越多。最近在沉积地质学和古生物学（SGP）的科学努力，导致了显着的进展，在地质记录的辐射校准和我们的解释性理解的深时间地球过程，不能推断出任何其他档案比地球？的甲壳。 尽管取得了这些进展，SGP社区在过去十年或更长时间内没有召开会议，讨论和制定一个SGP范围内的和一致的愿景，为我们更广泛的学科领域的未来研究。此外，支持小额赠款方案研究的资金水平越来越不足，限制了对令人兴奋的新科学机会和方向的追求，以及支持研究和指导活动所需的知识、文化和技术基础设施的发展。PI建议在SGP的各个子学科的代表之间进行思想交流，以确定沉积地质学和地球化学，深时古气候学和古生物学的关键研究问题和主题，这些问题和主题需要通过未来的研究来解决。研讨会的三个主要目标是（1）确定沉积，地球化学和古生物记录提供的高优先级的新的和新兴的研究机会，（2）制定和优先考虑一套指导？大挑战？为未来十年的研究在上述子学科，（3）划定关键仪器和设施，将需要支持这些新的和新兴的研究机会。

Defining Grand Challenges in Sedimentary Geology & Paleobiology Conveners: Isabel Montañez (University of California, Davis) & Charles Marshall (University of California, Berkeley) ABSTRACTThe Earth?s surface crust is host to (1) our mineral, hydrocarbon and water resources, (2) a full-spectrum record of past climate change, (3) a natural laboratory of the magnitude and rates of change in ecosystems under the range of past conditions, (4) the archive of the evolutionary history of life, including biodiversity and evolutionary innovation throughout Earth?s history, particularly during times of rapidly changing environmental conditions, and (5) a record of the processes that lead to or respond to natural hazards such as earthquakes, flooding, volcanic eruptions. Scientific investigation into these and related issues is primarily the purview of sedimentary geologists and geochemists and paleontologists - increasingly working in collaboration. Recent scientific efforts in sedimentary geology and paleobiology (SGP) have led to notable advances in radiometric calibration of the geologic record and in our interpretive understanding of deep-time earth processes that cannot be inferred from any other archive than the Earth?s crustal carapace. Despite these advances the SGP community has not convened in the past decade or more to discuss and develop a SGP-wide and coherent vision for the future of research in our broader disciplinary field. Furthermore, funding levels to support SGP research are increasingly inadequate limiting the pursuit of exciting new scientific opportunities and directions as well as the development of intellectual, cultural and technical infrastructure needed to support research and mentoring activities. PIs propose a workshop for the exchange of ideas among representatives of the various sub-disciplines in SGP in order to identify key research questions and topics in sedimentary geology and geochemistry, deep-time paleoclimatology, and paleobiology that need to be addressed by the community through future research. The three primary objectives of the workshop are (1) to identify high-priority new and emerging research opportunities offered by the sedimentary, geochemical and paleontological records, (2) to develop and prioritize a set of guiding ?grand challenges? for the coming decade of research in the aforementioned sub-disciplines, and (3) delineate key instrumentation and facilities that will needed to support these new and emerging research opportunities.
