Abstract

The Mesozoic and younger continent-ocean boundary zone extends across the central and eastern parts of the E-3 Transect (transect cross sections B-B′ and C-C′), which includes the piedmont, coastal plain, and Atlantic continental shelf, slope, and rise (Fig. 1). Deformation associated with continental rifting followed by the development of a typical “passive(Atlantictype) continental margin created the suite of distinctive crustal structures, sedimentary sequences, and geophysical signatures displayed on this part of the transect (Fig. 2) (Bally, 1981; Klitgord and others, 1988). In the description of the geological and geophysical framework of the transect that follows, we highlight the features incorporated into the map and cross sections. Detailed descriptions and discussions of these general crustal features are given by Klitgord and others (1988), Poag (1985b, 1991, 1992), Olsson and others (1988), Trehu and others (1989a), Manspeizer and others (1989), Costain and others (1989), Sheridan (1989), Sheridan and others (1988, 1991, 1993), Holbrook and others (1992), Poag and Ward (1993), and Holbrook and Kelemen (1993). Comprehensive papers describing the Mesozoic and younger structure and evolution of the Atlantic margin are presented in summary volumes by Poag (1985a), Vogt and Tucholke (1986), Sheridan and Grow (1988), Manspeizer (1988), Froelich and Robinson (1988), Pakiser and Mooney (1989), Hatcher and others (1989), and Poag and Graciansky (1992).

Synrift (Upper Triassic to Lower Jurassic) features are exposed only in a narrow band of the piedmont that extends 70-100 km west of the western edge of the coastal plain (fall line) (e.g., Manspeizer and others, 1989;
