An evaluation of water-quality data obtained at four streamflow daily-record stations in Idaho
Kenneth L. Dyer
1973, Water-Resources Investigations Report 73-30
Chemical data for four stream-gaging stations in Idaho, each having 6 to 22 years of available records, were analyzed to determine functional relations between concentrations of the major inorganic constituents, specific conductance, and stream discharge. Three of the four stations had sufficient available record for assessing changes in constituent relations...

Mantle convection and volcanic periodicity in the pacific; Evidence from Hawaii
H. R. Shaw
1973, Geological Society of America Bulletin (84) 1505-1526
The thermal-feedback theory of mantle melting proposed by Shaw in 1969 is found to be quantitatively consistent with data pertaining to the evolution of the Hawaiian Ridge. Applicable rate factors are estimated from relations between lava volumes and position along the ridge given in this paper and the radio-metric age...
Notes on the bromine pentafluoride technique of oxygen extraction
Irving Friedman, Jim D. Gleason
1973, Journal of Research of the U.S. Geological Survey (1) 679-680
The necessity to use a dry box when loading silicate samples into reaction vessels prior to fluorination is eliminated by the use of a simple loading technique. Data presented show the reproducibility of the fluorination reaction using this technique. Sodium fluoride, when added to saline waters prior to fluorination, improves...

Fossil forms of Amentiferae
Jack A. Wolfe
1973, Brittonia (25) 334-355
Review of the procedures used in determining fossil plant organs indicates that the many Cretaceous records of extant genera of “Amentiferae” based on leaves should be rejected as theoretically unreliable. Palynological data, in combination with some valid megafossil data, indicate that most recognizable members of “Amentiferae” are no older than...
