Collaborative Research: Stratigraphy, Geochemistry, and Paleoceanography of Organic Carbon-Rich Aptian-Albian Sequences

拟议的研究涉及多学科的方法 Aptian-Albian黑色页岩的研究：1） Aptian-Albian地层学与综合发展 高分辨率有孔虫和钙质超微化石 提出了生物地层学; 2）详细的沉积学和 Aptian-Albian的地球化学（有机;稳定同位素）研究 “黑色页岩”序列，以记录地层 缺氧与好氧条件的顺序以及由此产生的 有机物的类型和/或保存。 我们的研究将 包括对选定土地和DSDP/ODP进行深入调查 Aptian-Albian年龄序列， 古纬度和古环境 目标是：1） 更好地理解和约束模型， 白垩纪中期有机碳富集层的成因， 是世界上最好的碳氢化合物来源的主要部分; 2)研究黑色页岩沉积的动力， 构造、古海洋、海平面和气候事件; 来理解生物进化和 沉积（如锰）矿床的形成到OAE和OASE。

The proposed research involves a multidisciplinary approach to the study of Aptian-Albian black shales: 1) Refinement of Aptian-Albian stratigraphy with development of an integrated higher resolution foraminiferal and calcareous nannofossil biostratigraphy is proposed, and 2) detailed sedimentologic and geochemical (organic; stable isotopic) studies of Aptian-Albian "black shale" sequences in order to document the stratigraphic sequence of anoxic vs. oxic conditions and resulting changes in type and/or preservation of organic matter. Our study will involve intensive investigation of selected land and DSDP/ODP sequences of Aptian-Albian age from a broad spread of paleolatitudes and paleoenvironments. The objectives are: 1) to improve the understanding of and better constrain models for the origin of organic carbon-rich strata of mid-Cretaceous age, which are a major portion of the hydrocarbon source best of the world; 2) to investigate the forcing of black shale deposition by tectonic, paleoceanographic, eustatic and climatic events; and 3) to understand the relationships between biotic evolution and formation of sedimentary (e.g. Mn) ore deposits to OAEs and OASEs.
