Abstract

The lower Paleozoic (Silurian and Ordovician) carbonate stratal succession is divided into six unnamed stratigraphic units in the northern part of the Taylor Mountains D-1 1:63,360-scale quadrangle of southwestern Alaska. Several of these units have previously been recognized in the McGrath and Medfra quadrangles to the northeast in strata of the Nixon Fork subterrane of the Farewell terrane (Decker and others, 1994 ). These rocks occur along the south side of a prominent east-west-trending anticlinoria! axis exposed slightly to the north in the Sleetmute A-2 1:63,360-scale quadrangle. Rocks of the Nixon Fork subterrane are now thought to represent a continental margin sequence rifted from Siberia. The low thermal alteration indices exhibited by the rocks of this area have elicited interest for petroleum exploration. However, low total organic carbon (TOC) values from potential source rocks within this lower Paleozoic succession indicate low petroleum potential.
