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. ***

9304815名格罗斯曼Pis将进行稳定同位素研究，以调查与石炭纪冰川作用和泛古陆形成有关的古海洋学、古气候和地球化学变化。他们将以腕足类为基础，继续开发石炭系到P-Tr界线的同位素地层学，在北美和俄罗斯的更多地点进行采样。将进一步研究石炭纪的地理差异，考虑成岩作用，物种效应的校准，以及对原始贝壳化学保存的评价。将调查这种漂移/偏离的原因；氧同位素数据将用于测试北美和俄罗斯平台上的冰川作用和气候变化。***
