Structural and economic characteristics of New England mica deposits
Eugene N. Cameron, David M. Larrabee, A.H. McNair, James J. Page, Vincent E. Shainin, G. W. Stewart
1945, Economic Geology (40) 369-393
In connection with the intensive wartime exploitation of domestic mica deposits, the Geological Survey has been engaged in a comprehensive investigation of New England mica pegmatites. More than 200 pegmatites have been mapped and studied in detail and some hundreds of others have been given brief examination. The opportunity for...
Solution effects on elevated limestone terraces
J. E. Hoffmeister, H. S. Ladd
1945, Geological Society of America Bulletin (56) 809-818
Limestone terraces on a number of islands in the southwest Pacific show a well-developed wall or rampart along their seaward edges that apparently is formed by solution. Such rimmed terraces resemble, on a much enlarged scale, the solution facets developed on flat-lying joint blocks of limestone, recently described by Smith...
Stratigraphy and structure of west-central Vermont
Wallace M. Cady
1945, GSA Bulletin (56) 515-588
The lithologic units recognizable in the fossiliferous succession along southern Lake Champlain are structurally continuous with and traceable eastward into the “marble belt” of west-central Vermont immediately west of the Green Mountain Front. They are also traceable northward through west-central Vermont into a succession in northwestern Vermont bounded on the...
Glaciation of Mauna Kea, Hawaii 
Harold T. Stearns
1945, GSA Bulletin (56) 267-274
Wentworth and Powers have described four stages of glaciation on Mauna Kea, Hawaii. The type localities of the deposits have been studied by the writer, and only the latest or Makanaka deposits can be accepted as definitely glacial drift. The deposits of the first and second stages are paroxysmal explosion...
Petrography, structures, and petrofabrics of the Pinckneyville quartz diorite, Alabama
H.R. Gault
1945, GSA Bulletin (56) 181-246
The Pinckneyville quartz diorite complex underlies an area in eastern Alabama extending from the Coosa River in northwest Elmore County northeast through Coosa and Tallapoosa counties into Clay County.Dark-gray, coarse-grained quartz diorite gneiss constitutes the major part of the complex, but there are smaller amounts of granodiorite and granite gneiss....
Explosion‐breccia in the Wrangell district, southeastern Alaska
H.R. Gault
1945, Eos, Transactions, American Geophysical Union (26) 389-390
Unusual breccias were noted at several places in the vicinity of Groundhog and Glacier Basins, about 13 miles east of Wrangell on the mainland of southeastern Alaska, in 1942 and 1943. They are similar in some respects to the clastic dikes in Colorado described by Burbank [see 1 of “References”...
Minerals and mineral relationship of the clay minerals
Clarence S. Ross
1945, Journal of the American Ceramic Society (28) 173-183
The invitation to be the Edward Orton, Jr., Fellow Lecturer of the American Ceramic Society for 1945 is a very great honor and a privilege which one interested in the mineralogy of clays must heartily appreciate. Dr. Orton was a geologist as well as a founder of this Society, and...
Manganese content of the Shady dolomite in Bumpass Cove, Tennessee
John Rodgers
1945, Economic Geology (40) 129-135
The Shady dolomite in Bumpass Cove, Tennessee, contains deposits of hydrothermal sulphide minerals, and its residual clay contains oxidized manganese deposits. New chemical evidence bearing on the source of this manganese is presented.Chemical analyses of isolated components of sulphide-bearing dolomite show that the percentage of manganese is highest in country-rock...
The preparation of polished thin sections
G.C. Kennedy
1945, Economic Geology (40) 353-360
The relations in ores between opaque and translucent minerals can not be determined satisfactorily by independent examination of either polished surfaces or thin sections. Previous attempts to prepare polished thin sections by Tolman and Rogers, and thinned polished sections by Donnay, appear not to have been entirely successful. Canada balsam,...
Tularemia, an animal-borne disease
U.S. Division Of Wildlife Research
1945, Wildlife Leaflet 271
the disease tularemia continues to be of such importance in the United States that the Fish and Wildlife Service is constantly receiving requests for information on its nature and on the procedure recommended by field representatives of the Service in their work wiht the public. Such information is summarized in...
