Distribution of fluorine in unaltered silicic volcanic rocks of the western conterminous United States
R.R. Coats, W.D. Gross, L. F. Rader Jr.
1963, Economic Geology (58) 941-951
An investigation of more than 170 samples of glass-rich volcanic rocks of rhyolitic or rhyodacitic composition shows marked regional variations in the fluorine content. The uniformity of the class of rocks was controlled by index of refraction determinations on fused beads and by chemical analyses of about one-seventh of the total number. The fluorine content...

Factors influencing the pore volume of fine-grained sediments under low-to-moderate overburden loads
R.H. Meade
1963, Sedimentology (2) 235-242
An anomalous increase of pore volume with increasing depth in the range 0—1,900 ft. occurs in fine‐grained sediments along the east side of the San Joaquin Valley of Cali‐ fornia. Several possible causes for the anomaly were inferred from a literature search and from study of the core samples. Statistical analyses of...

1963, American Journal of Science (261) 668-682
Impact of a 0.4019-g steel sphere at 4.27 km/sec into Coconino Sandstone [Permian] from Meteor Crater, Arizona, produced a crater 11-12 cm across and 2.45 cm deep. The ejecta consist of sandstone fragments, disaggregated sand, splinters of sand...
The hydraulic geometry of a shallow estuary
W. B. Langbein
1963, International Association of Scientific Hydrology - Bulletin (8) 84-94
An analogy with entropy production in steady-state systems leads to a statement that the geometry of natural waterways is governed by two opposing influences: a) equal work per unit of area of bed, and b) minimum work done in the system as a whole. The resulting calculations applied to shallow, estuaries are verified...
Preliminary results of a study of calcium carbonate saturation of ground water in central Florida
William Back
1963, International Association of Scientific Hydrology - Bulletin (8) 43-51
The departure of ground water from equilibrium with calcite is being studied in central Florida. Measurements of pH, temperature, and concentration of bicarbonate made in the field are used with standard laboratory analyses of water samples to calculate an ion activity product (K) for calcium carbonate. The calculated Kiap is compared with the...

Anomalous gravity field in east-central California
Howard W. Oliver, Don R. Mabey
1963, Geological Society of America Bulletin (74) 1293-1298
Bouguer gravity values at about 11,000 stations in east-central California range from -14 mgal near Merced to -274 mgal in Long Valley. Gravity lows in the west and south parts of the San Joaquin Valley and over local basins south and east of the Sierra Nevada are produced by large thicknesses of Upper Cretaceous and Cenozoic...
Two pollen diagrams from southeastern Minnesota: Problems in the regional late-glacial and postglacial vegetational history
H.E. Wright Jr., Thomas C. Winter, Harvey L. Patten
1963, Geological Society of America Bulletin (74) 1371-1396
Kirchner Marsh and Lake Carlson are located 3 miles apart in Dakota County about 15 miles south of Minneapolis in the St. Croix moraine, which was formed by the Superior lobe during the Gary phase of the Wisconsin glaciation. During the Mankato phase that followed, the Des Moines lobe advanced to within...
Early pennsylvanian currents in the southern Appalachian Mountains
John Schlee
1963, Geological Society of America Bulletin (74) 1439-1451
Measurement of more than 1200 cross-beds in lower Pennsylvanian sandstones of the southern Appalachian Mountains reveals a broad pattern of sediment transport to the southwest and west. Most of the sand appears to have been derived from the east and to have moved south-westward parallel to the axis of the Appalachian geosyncline. The pattern...
Metasomatic origin of large parts of the Adirondack Phacoliths
A.E.J. Engel, C.G. Engel
1963, Geological Society of America Bulletin (74) 349-352
A metasomatic origin seems established for large parts of the granite phacoliths in the northwest Adirondack Mountains, New York. This conclusion is based upon the discovery and detailed mapping of a blurred but widespread stratigraphic sequence in the phacoliths. Highly complicated patterns of relict beds are defined by alternations of granitic gneiss, amphibolite, oligoclase-quartz...
Natural radioactivity in Washington County, Maryland
R.M. Moxham
1963, Geophysics (28) 262-272
Natural gamma-radioactivity patterns in Washington County, Maryland, reflect the principal variations in lithology. The highest radioactivity is associated with the more argillaceous parts of the geologic section and with soils derived from high-potassium carbonate rocks. Surface radiation intensity ranges from about 5 to 30 microroentgens per hour, of which the rocks contribute...

Hydrologic bench marks to distinguish the effects of climate vs. man
H.D. Wilson Jr.
1963, Groundwater (1) 13-14
There is a vital need for hydrologic data representing various environments that are free from the effects of man's activities. Without such data hydrologists will be stymied in distinguishing hydrologic changes caused by man from those caused by climate. To provide this background information, the U. S. Geological Survey is planning a nationwide hydrologic <span...

1963, Groundwater (1) 18-20
Vast quantities of saline ground water await new commercial uses and economical demineralization processes for recognition as a valuable resource. Saline ground water is more widely distributed than any other natural resource, occurring throughout the United States and in geologic formations ranging from the oldest to the youngest. The Coastal Plain has the...
Gibson peak pluton: A discordant composite intrusion in the southeastern Trinity Alps, northern California
Peter W. Lipman
1963, Geological Society of America Bulletin (74) 1259-1280
Gibson Peak pluton is the most discordant of several dominantly granitic intrusions in the Trinity Alps of northern California. It formed during Nevadan (Late Jurassic) deformation by emplacement of at least five discrete rock units that define a successively more silicic series, ranging from hypersthene gabbro to trondhjemitic tonalite. Contact features suggest that several...

Epigenetic, diplogenetic, syngenetic, and lithogene deposits
T. S. Lovering
1963, Economic Geology (58) 315-331
Much of the disagreement over "epigenetic" And "Syngenetic" Deposits Is Semantic; Some Ores And altered rocks are in part syngenetic and in part epigenetic and for them the term "diplogenetic" is proposed. All these terms are primarily time terms related to the contemporaneity of the deposit and the enclosing rock, but...
