Dolomite pseudomorphs after crystals of aragonite [Wyoming]
D. A. Andrews, W. T. Schaller
1942, American Mineralogist (27) 135-140
The flat hexagonal crystals from the Big Horn Basin, Wyoming, Iocally called "Indian Pennies," are shown to consist of dolomite pseudomorphous after crystals of aragonite....
Correlation of the outcropping cretaceous formations of the Atlantic and Gulf Coastal Plain and trans-Pecos Texas
L. W. Stephenson, P.B. King, W. H. Monroe, R. W. Imlay
1942, Geological Society of America Bulletin (53) 435-448
This is Number 9 of a series of correlation charts prepared by the Committee on Stratigraphy of the National Research Council, which will cover the post-Proterozoic sedimentary formations of North America. For general information about the project the reader is referred to the general introduction preceding this paper. The senior...
Reconnaissance survey of the Roberts Mountains, Nevada
C.W. Merriam, C.A. Anderson
1942, Geological Society of America Bulletin (53) 1675-1727
The Roberts Mountains region, central Nevada, provides an excellent section of Paleozoic rocks ranging from Upper Cambrian to Permian. Major low-angle thrusting is indicated by deformed Ordovician strata resting on Paleozoics of varying age. Overlying a thick breccia zone, the upper thrust plate consists of sandstones, andesitic flows and tuffs,...
Intrusive rocks in the Blue Ridge plateau, Virginia
Anna Stose
1942, Eos, Transactions, American Geophysical Union (23) 342-342
An injection complex of early pre‐Cambrian age is exposed in the Elk Creek anticline in Grayson County, Virginia. There, sedimentary rocks and diorite have been intruded by the Striped Rock and the Carsonville granites. The granites have metamorphosed, injected, reacted with, and replaced the older rocks to form many mixed...
Monthly evapo‐transpiration losses from natural drainage‐basin
Walter B. Langbein
1942, Eos, Transactions, American Geophysical Union (23) 604-614
With limited restrictions the hydrologic cycle in a given area may be expressed essentially as follows: P = (R + E + ΔFm) in which P represents the precipitation during a given period, R that portion which has reached or will reach the stream‐channel either through surface or subsurface paths,...
