Notes on the structural geology of Puerto Rico
C. A. Kaye
1957, GSA Bulletin (68) 103-118
Two major structural and stratigraphic rock units occur in Puerto Rico: the older complex, ranging in known age from Late Cretaceous to late Paleocene or early Eocene and the middle Tertiary sequence, ranging from late Oligocene possibly to late Miocene.

The Salt Wash is the basal member of the Upper Jurassic Morrison Formation in parts of Utah, Colorado, Arizona, and New Mexico. Deposited by streams, it comprises lenticular beds of cross-laminated sandstone irregularly interbedded with mudstone, siltstone, claystone, and horizontally laminated sandstone. The term "lithofacies," as used in this paper,...

K. B. Schroeder, C. H. Hembree
1957, Eos, Transactions, American Geophysical Union (38) 768-773
Basically, any theory consists of a set of assumptions and various conclusions which are logically derived therefrom. An assumption, as the term is to be used here, may be based on an observed fact or relationship, a definition, an undefined (but generally accepted and understood) concept; or it may be...
Thermal waters of volcanic origin
Donald E. White
1957, GSA Bulletin (68) 1637-1658
Waters of widely differing chemical compositions have been considered at least in part volcanic in origin, and are commonly associated with each other in the same area. Do any or all of these types contain volcanic components, and if so, how are the different types derived?To determine the probable characteristics...
Modified determination of radium in water
F. B. Barker, L. L. Thatcher
1957, Analytical Chemistry (29) 1573-1575
The proposed method embodies a barium sulfate carrier precipitation, filtration through molecular filter membranes, and collection of activity after prescribed aging period. The method is sufficiently accurate and precise to indicate the potability of water and for use in general studies of radium in chemical hydrology. Amounts of radium as...
Modified zirconium-Eriochrome Cyanine R determination of fluoride
L. L. Thatcher
1957, Analytical Chemistry (29) 1709-1712
The Eriochrome Cyanine R method for determining fluoride in natural water has been modified to provide a single, stable reagent solution, eliminate interference from oxidizing agents, extend the concentration range to 3 p.p.m., and extend the phosphate tolerance. Temperature effect was minimized; sulfate error was eliminated by precipitation. The procedure...
Structure and growth of scales of yellow perch of Green Bay
Leonard S. Joeris
1957, Transactions of the American Fisheries Society (86) 169-194
The appearance of the scales of yellow perch differs with the location on the fish's body. Comparison of scales of Green Bay perch taken above and below the lateral line reveals the former to have more sharply defined circuli and to exhibit fewer false annuli and less of the shading...
Geographic names of Antarctica
U.S. Board on Geographic Names, Department of the Interior, Meredith F. Burrill, Kenneth J. Bertrand, Fred G. Alberts
1956, Gazetteer 14
The geographic nomenclature of Antarctica was long in need of an overall systematic treatment, objective in approach and based upon thorough examination of all the evidence. The results of such treatment over a period of about three years were presented in Geographical Names of Antarctica, Special Publication No. 86 of...
Fifty-sixth Christmas Bird Count. 147. Southern Dorchester County, Md
Fred A. Johnson, B. Kenneth Williams, J.D. Nichols, J.E. Hines, W. L. Kendall, G.W. Smith, David F. Caithamer
1956, Audubon Field Notes (10) 565-583
Summary and Recommendations: We suggest that managers are approaching the limits of their ability to improve waterfowl harvest management, primarily because the information needed to make better decisions is being sacrificed by the current approach to setting regulations. We propose an actively adaptive management strategy in which regulatory...

Duttonite, a new quadrivalent vanadium oxide from the Peanut mine, Montrose County, Colorado
Mary Eleanor Thompson, Carl Houston Roach, Robert Meyrowitz
1956, Trace Elements Investigations 582
Duttonite, a new quadrivalent vanadium oxide from the Peanut mine, Montrose County, Colo., has the formula VO(OH)2. The mineral occurs as crusts and coatings of pale-brown transparent platy crystals, as one of the first oxidation products of montroseite ore. It is associated with melanovanadite and abundant crystals of hexagonal...
Water resources of the Mobile area, Alabama, with a section on salinity of the Mobile River
W.H. Robinson, William J. Powell, Eugene Brown, U.S. Army Corps of Engineers
1956, Circular 373
Water is an abundant resource of the Mobile area. The Mobile River has an estimated average flow of 60, 000 cubic feet per second (cfs), or about 39,000 million gallons per day (mgd). It is the largest single source of water. Water is available in substantial quantities from the many...

Water requirements of the aluminum industry
Howard L. Conklin
1956, Water Supply Paper 1330-C
Aluminum is unique among metals in the way it is obtained from its ore. The first step is to produce alumina, a white powder that bears no resemblance to the bauxite from which it is derived or to the metallic aluminum to which it is reduced by electrolytic action in...
Water requirements of the carbon-black industry
Howard L. Conklin
1956, Water Supply Paper 1330-B
Carbon blacks include an important group of industrial carbons used chiefly as a reinforcing agent in rubber tires. In 1953 more than 1,610 million pounds of carbon black was produced, of which approximately 1,134 million pounds was consumed by the rubber industry. The carbon-black industry uses small quantities of water...

Isadore Zietz, Roland G. Henderson
1956, Geophysics (21) 794-814
Model experiments were made to devise a rapid method for calculating magnetic anomalies of three-dimensional structures. The magnetic fields of the models were determined using the equipment at the Naval Ordnance Laboratory, White Oaks, Md. An irregularly shaped mass was approximated by an array of prismatic rectangular slabs of constant...
