This proposal requests funds for a detailed study of the tectonic evolution and depositional history of Permian sedimentary rocks on the Central Basin Platform, Permian Basin. The Central Basin Platform (CBP) is similar to other foreland uplifts. The results from an integrated study of Permian sequence stratigraphic relationships across the platform, geophysical data, and quantitative subsidence analyses will provide important information about the tectonic origin and depositional history of this complex structure. This study also will present an unique intrabasinal test of sequence stratigraphic concepts. The objectives of the proposed research are: 1) to determine the late Paleozoic tectonic evolution of the CBP through detailed analysis of pre-Leonardian structures and uplift history of the CBP; 2) to better constrain tectonic models for the origin of the Permian Basin area; 3) to integrate structural analyses of the CBP into larger-scale models of the tectonic evolution of the Marathon- Ouachita foreland and the Ancestral Rocky Mountains; 4) to determine the Permian subsidence history along several east-west transects across the CBP and adjacent parts of the Midland and Delaware Basins; 5) to determine the relative effects of subsidence, eustasy, sedimentation rate, and paleogeographic position of the evolution of Permian depositional facies from the platform interior and across platform-to-basin transitions around the CBP; 6) to identify the controls that pre-Premian structures of the CBP have on Permian subsidence history and facies architecture; 7) to develop a better understanding of the origin of foreland uplifts and their response to convergence events; and 8) to relate all the of the above objectives to future hydrocarbon exploration and production strategies on the CBP.

这项提案要求提供资金，以详细研究二叠纪盆地中央盆地台地二叠纪沉积岩的构造演化和沉积史。中央盆地地台(CBP)与其他前陆隆起相似。对整个地台的二叠系层序地层关系、地球物理数据和定量沉降分析的综合研究结果将为这一复杂构造的构造成因和沉积史提供重要信息。这项研究还将提出一种独特的盆地内层序地层学概念测试。这项研究的目的是：1)通过对CBP的前列昂纳第构造和隆升历史的详细分析，确定CBP的晚古生代构造演化；2)更好地约束二叠纪盆地地区的构造模式；3)将CBP的构造分析整合到马拉松-瓦奇塔前陆和原始落基山脉的更大尺度构造演化模型中；4)确定横跨CBP和米德兰盆地和特拉华盆地相邻部分的几个东西走向的二叠纪沉降史；5)从CBP周围的台地内部和跨越台盆过渡，确定二叠纪沉积相演化的沉降史、隆起期、沉积速率和古地理位置的相对影响；6)识别CBP前前叠纪构造对二叠纪沉降史和相结构的控制作用；7)更好地了解前陆隆起的起源及其对汇聚事件的响应；8)将上述所有目标与CBP未来的油气勘探和生产战略联系起来。
