Collier, Frank L. Hess, P. S. Smith, and Alfred II. Brooks: The gold placers of parts of the Seward peninsula. Bulletin no. 328, U. S. Geological Survey, The Rampart region has yielded some Upper Carboniferous fossils, found in a gray and black argillaceous and siliceous slate by Prindle. 107 These rocks have been but little studied and their relation to the Devonian is not known. Lithologically they do not appear to resemble either the Nation river or the younger Carboniferous of the upper river. Spurr108 described some limestones and carbonaceous argillites which occur on the Yukon 20 miles below the mouth of Minook creek, and on the basis of some fragmentary fossil plants assigned them to the Tahkandit. A heavy conglomerate and argillite series in the White River region, 108 termed the Willesley formation, was provisionally assigned to the Carboniferous or Devonian on the basis of a few invertebrate fossils. It seems quite possible that this may be a synchronous deposit with the Xation River. In the Upper Copper River basin Mendenhall110 found a series of conglomerates, quartzites, and tuffs which he termed the Chisna formation and provisionally correlated with the Willesley. A heavy conglomerate also occurs along the western foot of the Alaska range, and this, too, may be Carboniferous. If these conglomerates are synchronous deposits, they probably represent a far-reaching period of erosion. In the Copper-White River region it appears to be the oldest recognizable Paleozoic, resting immediately on the metamorphic rocks. If it pr. . . This item ships from La Vergne,TN.<
