High-alumina kaolinitic clay in the United States, exclusive of Alaska and Hawaii
Helen R. Mark
1963, Mineral Investigations Resource Map 37
The general distribution of high-alumina kaolinitic clay deposits in the United States (exclusive of Alaska and Hawaii) is shown on the accompanying map. The locations of mines, pits, and prospects are shown by appropriate symbols. Certain clay-bearing areas are shown by patterns that designate the geologic age of the deposits....
Niobium and tantalum in the United States, exclusive of Alaska and Hawaii
Raymond Laurence Parker
1963, Mineral Investigations Resource Map 36
The accompanying map shows the location of the principal known deposits of niobium and tantalum minerals in the United States, exclusive of Alaska and Hawaii. Symbols of different shapes are used to depict deposits of different geologic types, and large symbols denote deposits with a record of production. Small symbols...
Placer tin deposits in central Alaska
Robert Mills Chapman, Robert Roy Coats, Thomas G. Payne
1963, Open-File Report 63-15
Placer tin, in the form of cassiterite (Sn02) and (or) tinstone (fragments including cassiterite and some vein or rock material), is known or reported in deposits that have been prospected or mined for placer gold in four areas adjacent to the Yukon River in central Alaska, 120 to 240 miles...
Pleistocene marine microfauna in the Bootlegger Cove Clay, Anchorage, Alaska
R.A.M. Schmidt
1963, Science (141) 350-351
Ostracods and Foraminifera, associated with molluscs, indicate a marine depositional environment for part of the Bootlegger Cove Clay. The definite Arctic and North Atlantic affinities of the microfauna suggest a possible migration through the Bering-Chukchi seaway during the late Pleistocene....
Intraspecific differences in serum antigens of red salmon demonstrated by immunochemical methods
G.J. Ridgway, G.W. Klontz, C. Matsumoto
1962, International North Pacific Fisheries Commission Bulletin (8) 1-9
The sera of most Alaskan red salmon (Oncorhynchus nerka Walbaum) were found to contain at least 14 antigenic components when tested by the double diffusion precipitin analysis method of Ouchterlony with antisera prepared in rabbits. Two of these components, designated antigens I and II, were missing from 116 of 125...
Data on uranium and radium in ground water in the United States, 1954 to 1957
R. C. Scott, F. B. Barker
1962, Professional Paper 426
This report is one of a series resulting from a study by the U.S. Geological Survey to determine the occurrence and distribution of naturally radioactive substances in water. From 1954-57 uranium and radium concentrations were determined in 561 samples, mainly of ground water, having wide geologic and geographic distribution. These...
Talc and soapstone in the United States, exclusive of Alaska and Hawaii
A.H. Chidester, Henry Wilson Worthington
1962, Mineral Investigations Resource Map 31
The locations of talc and soapstone deposits in the United States (exclusive of Alaska and Hawaii) arc shown on the accompanying map. The two types are distinguished by the shape of symbols; the relative importance of the deposits, expressed in broad ranges of tonnage, is indicated by the size of...
