L. V. Benson, D. L. Leach
1979, Journal of Geochemical Exploration (11) 227-248
During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide an understanding of the transport of uranium within...
International cooperation in water resources
J.R. Jones, R.M. Beall, E.V. Giusti
1979, GeoJournal (3) 481-487
Advancements in hydrology proceeded slowly until the late 1800's when new ventures created a surge of interest and accomplishment. Progress waned again until the middle 20th century when an International Hydrological Decade was conceived, eventually receiving wide multinational support from governmental agencies and nongovernmental institutions. Organized by UNESCO, the Decade...

R.E. Peck, R. M. Forester
1979, Review of Palaeobotany and Palynology (28) 223-236
The systematics of four species belonging to the genus Platychara (Charophyta) from the Western Hemisphere is discussed. Three of the species, as defined herein, occur in Cretaceous and Paleocene rocks from Mexico through South America. The type species, P. compressa (Peck and Reker) Grambast, also of Cretaceous and Paleocene age,...
Surface faults in the gulf coastal plain between Victoria and Beaumont, Texas
Earl R. Verbeek
1979, Tectonophysics (52) 373-375
Displacement of the land surface by faulting is widespread in the Houston-Galveston region, an area which has undergone moderate to severe land subsidence associated with fluid withdrawal (principally water, and to a lesser extent, oil and gas). A causative link between subsidence and fluid extraction has been convincingly reported in...
U-Th-Pb geochronology of the Massabesic Gneiss and the granite near Milford, South-Central New Hampshire: New evidence for avalonian basement and taconic and alleghenian disturbances in Eastern New England
J. N. Aleinikoff, R. E. Zartman, J.B. Lyons
1979, Contributions to Mineralogy and Petrology (71) 1-11
U-Th-Pb systematics for zircon and monazite from Massabesic Gneiss (paragneiss and orthogneiss) and the granite near Milford, New Hampshire, were determined. Zircon morphology suggests that the paragneiss may be volcaniclastic (igneous) in origin, and thus the age data probably record the date (minimum of 646 m.y.) at which the rock...

1979, Physics of the Earth and Planetary Interiors (19) 331-336
Cancellation of extraterrestrial magnetic disturbances by taking simple differences between total field readings at spaced stations is imperfect. It is shown that improvement is possible when three component observatory data are available from a single station in the general, but not necessarily immediate, vicinity of an array of total field...
Probability weighted moments: Definition and relation to parameters of several distributions expressable in inverse form
J. Arthur Greenwood, J. Maciunas Landwehr, N.C. Matalas, J.R. Wallis
1979, Water Resources Research (15) 1049-1054
Distributions whose inverse forms are explicitly defined, such as Tukey's lambda, may present problems in deriving their parameters by more conventional means. Probability weighted moments are introduced and shown to be potentially useful in expressing the parameters of these distributions....
Monitoring seismic wave velocities in situ
