Late Neogene Uplift of the Fairweather Ground on the Basis of Bathymetric and Seismic Data from the Gulf of Alaska
Pliocene to Pleistocene glacial-marine deposits adjacent to the Fairweather Ground basement in the Gulf of Alaska are the focus for seismic interpretation using public domain seismic reflection data. The late Tertiary and early Quaternary sections of the Yakataga Formation record a glacial/ intergla...
