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 Grossman pi将进行稳定同位素研究，研究与石炭纪冰川作用和泛大陆形成相关的古海洋学、古气候和地球化学变化。他们将继续发展以腕足动物为基础的石炭纪至P-Tr边界的同位素地层学，在北美和俄罗斯的更多地点取样。石炭系地理分异将进一步研究，考虑成岩作用、物种效应校正和原始壳化学保存评价。我们将调查这种偏离/分歧的原因；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。＊＊＊
