TECTONIC CONTROLS ON THE DEVELOPMENT OF UNCONFORMITIES - THE NORTH SLOPE, ALASKA

Abstract:

The geology of northern Alaska is defined by two complementary, synchronous tectonic events. Opening of the Canada basin breached the south facing Ellesmerian passive margin in the Late Jurassic, cutting off northerly derived sediment and initiating thermal subsidence of the north facing Beaufort passive margin.
