U.S.-China Cooperative Research (Geology): Analysis of the Tectonic Origin and Stratigraphy of the Bohai Basin

路易斯安那州立大学巴吞鲁日分校(路易斯安那州立大学巴吞鲁日分校)关于《渤海盆地构造成因与地层分析》的建议，中华人民共和国中国石油勘探开发研究院薛书豪先生是由美国国家科学基金会赞助的。渤海盆地是位于中国东部的一个大型新生代盆地，拥有多达1万个以河流和湖泊沉积为主的盆地。尽管对盆地进行了广泛的研究，但构造与沉积之间的关系以及沉积环境仍然没有答案。研究所和路易斯安那州立大学之间拟议的联合研究的目的是解决其中一些问题。拟议研究的第一阶段将确定(1)构造成因，(2)盆地充填的地层学，(3)盆地的沉积体系。拟议研究的第二阶段将利用第一阶段形成的知识：(1)制定可用于区分和确定哪些因素(气候、构造、沉积物供应、基准面变化等)的标准。控制沉积作用；(2)发展现代层序地层学概念应用于湖相岩石的技术；(3)检验现有的裂谷或拉开盆地的模型。拟议研究的主要任务将是：(1)建立沉降曲线，以提供关于盆地构造、基准面变化和沉降史的信息，并为解释岩石圈结构和力学提供依据，(2)盆地内断裂和褶皱的几何学分析，(3)沿断裂运动的估计，(4)沉积层序的三维几何图形的绘制，(5)沉积环境的解释，以及(6)评估构造、基准面波动、气候和其他因素对沉积的影响。用于完成这些任务的数据将包括测井、岩心和地震反射剖面。

This proposal on "Analysis of the Tectonic Origin and Stratigraphy of the Bohai Basin, between Dag Nummedal of Louisiana State University Baton Rouge (LSU), and Mr. Xue Shuhao of the Research Institute for Petroleum Exploration and Development (RIPED) of the People's Republic of China is sponsored by NSF. The Bohai basin is a large Cenozoic basin in eastern China with up to 10,000 predominantly fluvial and lacustrine sediments. Despite extensive research on the basin, the relationship between tectonics and sedimentation, and the depositional environments remain unanswered. The purpose of the proposed joint research between the RIPED and LSU is to address some of these questions. The first phase of the proposed research would determine (1) tectonic origin, (2) stratigraphy of the basin fill, and (3) depositional systems of the basin. The second phase of the proposed research would employ the knowledge developed in the first phase to: (1) develop criteria that may be used to differentiate and identify what factors (climate, tectonics, sediment supply, base.level changes, etc.) controlled sedimentation, (2) develop techniques which would allow modern concepts of sequence stratigraphy to be applied to lacustrine rocks, and (3) test existing models for rift or pull.apart basins. The major tasks of the proposed research would be to: (1) construct subsidence curves in order to provide information on the history of tectonics, base.level changes, and subsidence in the basin and to provide a basis for interpreting lithospheric structures and mechanics, (2) analyze the geometry of faults and fold in the basin, (3) estimate the sense of motion along faults, (4) map the 3.D geometry of depositional sequences, (5) interpret depositional environments, and (6) evaluate the effects of tectonics, fluctuations in base level, climate, and other factors on sedimentation. The data used to accomplish these tasks would include well logs, core, and seismic reflection profiles.
