“…18), the margin has seven main elements: 1) a rifted Whether Permian rocks exist under the Baltimore trough is not known, nor do we know how to distinguish them from the rocks in syntectonic rift-basins of Late Triassic and Early Jurassic age. Notwithstanding these minor differences, both margins appear to fit the models of Falvey (1974) and Kinsman (1975) for Atlantic-type margins, where a rift phase is followed by a broad subsidence phase. Falvey's model involves block faulting and accumulation of red beds and evaporite deposits (see Van Houten, 1977), and Kinsman's model involves subsidence and accumulation of a massive sedimentary prism over deposits of an earlier formed phase.…”
