EAR-0543952EILERThe goals of this work are to create a data set that demonstrates the capabilities and limitations of clumped isotope thermometry for reconstructing soil temperature records, and that guides sampling and analytical protocols required to generate reliable records. Based on our previous work on Miocene and recent Bolivian Altiplano soils, we believe there is a reasonable chance of succesfully completing this task within 1 year, and that this work will require ca. 50 'clumped isotope' analyses, supported by SEM, optical microscopy and electron microprobe characterizations of analyzed samples.Specifically, we will conduct a 1-year study of the stable isotope systematics, including 'clumped isotope thermometry' measurements of several suites of modern and recent soil carbonates, for which average growth temperatures can be independently estimated based on meteorological records and/or independent paleoclimatic reconstructions. The suites we will examine include recent soil carbonates sampled from the north-central Altiplano plateau and the western United States (principally central Wyoming and the Colorado plateau).

EAR-0543952Eiler这项工作的目标是创建一个数据集，该数据集证明了集成的同位素温度计的功能和局限性以重建土壤温度记录，并指导采样和分析协议，以生成可靠的记录。 根据我们以前关于中新世和最近的玻利维亚阿尔特普拉诺土壤的工作，我们认为有合理的机会在1年内成功完成这项任务，这项工作将需要CA。 50个“团结的同位素”分析，由SEM，光学显微镜和分析样品的电子显微探针表征支持。具体地说，我们将对稳定的同位素系统学进行1年的研究，包括“集结的同位素温度计”，包括基于现代和较新的碳酸盐的数量典范，对现代和近期培养基的测量，并具有独立性的独立性或独立性估算重建。我们将研究的套件包括最近从中北部阿尔特普拉诺高原和美国西部采样的土壤碳酸盐（主要是怀俄明州中部和科罗拉多高原）。
