Sedimentology and structural geology of the Endicott Mountains allochthon, central Brooks Range, Alaska
The Endicott Mountains allochthon is an east-west striking stack of north-northwest vergent thrust sheets which were emplaced during late Mesozoic and Cenozoic (Brookian) orogenesis. Thrust sheets in the allochthon are ...
Separating tectonic, eustatic, and episodic depositional processes in the stratigraphic record of the basins of southeastern and northwestern Australia (Cretaceous Period)
Four dynamic processes interact to create the stratigraphic record in a basin: climate, sediment supply, eustasy, and subsidence. To identify the contribution of each of these processes, techniques that can uniquely separate ...
