引言由缅因至弗罗里达州的大西洋大陆边缘是典型的被动陆缘。由于裂谷作用,破裂以及北美和非洲大陆的漂移,海岸平原巨厚的中-新生代沉积盖层、陆棚、陆坡以及陆基跨越了三类基底:大陆的、过渡的、大洋的基底。内陆棚下陆壳,海岸平原以及近陆部位的明显标志是存在着出露的未出露的由不对称半地堑组成的裂谷盆地。外陆棚下的过渡型陆壳和布莱克高原下的陆壳深度下沉,下伏于五种主要沉积盆地:乔治滩盆地、巴尔的摩谷槽、卡罗来纳 INTRODUCTION The margins of the Atlantic Ocean from Maine to Florida are typically passive margins. Due to rifting, rupture, and drifts in North America and Africa, the vast Mesozoic-Cenozoic sedimentary cover, continental shelf, continental slope, and land-based coastal plains cross three types of basins: continental, transitional, and oceanic. The obvious hallmark of the continental shelf submarine crust, coastal plain and inland parts is the existence of undisclosed rift basins that consist of asymmetric half-graben. The transitional continental crust beneath the continental shelf and the continental crust beneath the Black Plateau sink deeply and fall into five main sedimentary basins: the Georgetown Basin, the Baltimore Valley, the Carolina
