...Jennifer Vezina; Brian Jones; Derek Ford Abstract The Ironshore Formation (up to 19 m thick) in the Rogers Wreck Point area of Grand Cayman is divided into the unconformity-bounded units A, B, C, and D. The unconformities are highlighted by caliches and/or terra rossa. Th/U dates from aragonitic...

... of mid-Late Devonian or younger age (terrane wreck model). In Newfoundland, the repetition is inferred to be the result of oblique, dextral offset of ca. 250 km. In the Quebec Embayment, the Iapetan paired magmatic belts are repeated twice in the limbs of a Z-shaped orocline related to oblique, dextral...

... sets of breaches at Anegada are evident in bare-earth lidar topography south of Cow Wreck High Point ( Fig. B1B ). Their seaward limits are distinctly separated by geomorphic superposition of ridges on this accretionary part of the island. The inner, earlier set of breaches coincides with a muted beach...
