Figure 4. Simplified drawing of oblique subduction model, where platform is affected by tectonic erosion related to oblique subduction of the southeastern Bahama platform and Atlantic fracture zone highs [McCann and Sykes, 1984]. The movement of the North America plate opposite to the Caribbean plate is shown for three different time periods: (a) middle Miocene (15 Ma), (b) late Miocene (7 Ma), and (c) Holocene. The plate motion vector of DeMets et al. [1996] has been used for calculation.
