Planform Recognition and Implications of a Cretaceous-age Continental-scale River Avulsion Node in the Western Interior Basin, Alberta, Canada
Controls On Sedimentation and Cyclicity of the Boquillas and Equivalent Eagle Ford Formation from Detailed Outcrop Studies of Western and Central Texas, U.S.A.
COVER EXPLANATION.—Variably thick aeolian cross sets of the Jurassic Page Sandstone, Arizona, USA. These cross sets are composed of steeply dipping grainflow and wind-ripple strata, and can transition into shallowly dipping wind-ripple strata near the base. The variability in thickness is a product of the migration rate of the dunes, aggradation rate of the bed, and variability in dune scour depths (see Cardenas et al. and Swanson et at al., this issue).
