The Lough Foyle Basin is a half-graben that straddles the border between Northern Ireland and Republic of contains sediments range in age from Lower Carboniferous to Holocene. basin’s post-rift succession represented by Penarth Group Lias Group. lithostratigraphy biostratigraphy interval are revised using new borehole material existing outcrop.

Stratigraphy, Sedimentology, and Sequence Stratigraphy of the Lower Triassic Sinbad Formation, San Rafael Swell, Utah

The Lower Triassic Sinbad Formation (Thaynes Group) in the San Rafael Swell of east-central Utah (11-18 m thick) represents the maximum flooding zone and at least part of the highstand systems tract of a 185+ m thick depositional sequence. The Sinbad Formation conformably overlies siliciclastic tidal flat, fluvial channel and carbonate peritidal deposits of the Black Dragon Formation, a transgr...

Magnetic polarity stratigraphy and paleolatitude of the Triassic^Jurassic Blomidon Formation in the Fundy basin (Canada): implications for early Mesozoic tropical climate gradients

A magnetic polarity stratigraphy is established for a continuously cored 360 m thick section of the entire cyclical lacustrine sequence and part of the sandy fluvial and eolian basal sequence of the Late Triassic Blomidon Formation in the Fundy basin in Nova Scotia (Canada). In conjunction with published results for the Newark and Dan River basins, the Fundy basin record allows us to precisely ...
