项目摘要
9304815 Grossman PIs will conduct a stable isotope study to investigate the paleoceaonographic, paleoclimatic and geochemical changes associated with Carboniferous glaciation and the formation of Pangaea. They will continue to develop isotope stratigraphy for the Carboniferous to P-Tr boundary based on brachiopods, sampling more locations in North America, as well as in Russia. A Carboniferous geographic divergence will be further studied, with consideration of diagenesis, calibration of species effects, and evaluation of preservation of original shell chemistry. The cause of this excursion/divergence will be investigated; oxygen isotope data will be used to test for glaciation and climate change on the North American and Russian platforms. ***
小行星9304815 研究员将进行稳定同位素研究,以探讨与石炭纪冰川作用和泛古陆形成有关的古海洋地理、古气候和地球化学变化。 他们将继续根据腕足动物,在北美和俄罗斯的更多地点取样,为石炭纪至P-Tr边界开发同位素地层学。 将进一步研究石炭纪的地理分歧,考虑成岩作用、物种效应的校准以及原始外壳化学保存的评估。 将调查这种偏移/分歧的原因;氧同位素数据将用于测试北美和俄罗斯平台的冰川作用和气候变化。 ***
