Rapid determination of filterable residue in natural waters
Herbert E. Allen, Charles W. Bacon
1969, Journal - American Water Works Association (61) 355-356
The most widely used procedures for determining filterable residue (total dissolved solids) in water are macromethods given in Standard Methods. Although macromethods give good results, they require large amounts of water and long drying times. This report describes a microtechnique for determining filterable residue that requires only 0.05...
Rearing of sea lamprey, Petromyzon marinus, embryos in distilled water
George W. Piavis, John H. Howell
1969, Copeia (1969) 204-205
Most embryological studies of lampreys in the Great Lakes have been conducted with filtered water from Lake Huron. Although this water was entirely satisfactory for the earlier work, the present need for knowledge of the effects of various compounds on embryological development requires that the initial medium be sterile....
Insecticides and the Great Lakes
Robert E. Reinert
1969, Limnos (2) 3-9
Cracks in the perfect image of DDT appeared when traces of the insecticide began to show up in a wide variety of organisms throughout the world. As more and more people investigated this problem, it became increasingly evident that terrestrial and aquatic animals were accumulating comparatively high concentrations of...

Merryll M. Bailey
1969, Journal of the Fisheries Research Board of Canada (26) 1289-1299
Studies of age, growth, and maturity were based on 1760 fish collected in western Lake Superior in 1964-65. The body:scale relation was curvilinear and the curve had an intercept of 1.65 inches on the length axis. The weight increased as the 2.85 power of the length. Some fish formed an...

M.C. Blake Jr., W. P. Irwin, R. G. Coleman
1969, Tectonophysics (8) 237-246
Rocks of the blueschist (glaucophane schist) facies occur throughout the world in narrow tectonic belts associated with ultramafic rocks. In the Coast Range province of California, blueschist rocks are devloped in the eugeosynclinal Franciscan Formation of Late Mesozoic age. The blueschist rocks form a narrow belt for more than 800...
Interstitial brines in playa sediments
B.F. Jones, A. S. Van Denburgh, A.H. Truesdell, S.L. Rettig
1969, Chemical Geology (4) 253-262
Study of several closed drainages in the Great Basin has shown that the interstitial solutions of shallow, fine-grained playa deposits store a large quantity of dissolved solids and are often more concentrated than associated lakes and ponds, except in peripheral zones of stream or ground-water inflow. These interstitial fluids,...
Determination of traces of silver in waters by anion exchange and atomic absorption spectrophotometry
T. T. Chao, M. J. Fishman, J.W. Ball
1969, Analytica Chimica Acta (47) 189-195
A method has been developed for the accurate determination of 0.1–1 μg of silver per liter of water. The method permits stabilization of silver in water without loss to container walls. Optimum conditions have been established for the complete recovery of silver from water with an anion-exchange column, for quantitative...
The relationship of the rare-earth composition of minerals to geological environment
M. Fleischer, Z. S. Altschuler
1969, Geochimica et Cosmochimica Acta (33) 725-732
It has been known for a long time that the composition of the lanthanides in minerals is controlled to a large degree by crystallo-chemical factors, but is also greatly influenced by changes in geological environment. In general, igneous rocks rich in silica are favourable for the concentration of the heavy...
Geochemistry and origin of formation waters in the western Canada sedimentary basin-I. Stable isotopes of hydrogen and oxygen
B. Hitchon, I. Friedman
1969, Geochimica et Cosmochimica Acta (33) 1321-1349
Stable isotopes of hydrogen and oxygen, together with chemical analyses, were determined for 20 surface waters, 8 shallow potable formation waters, and 79 formation waters from oil fields and gas fields. The observed isotope ratios can be explained by mixing of surface water...
Geochemistry of pore waters from Shell Oil Company drill holes on the continental slope of the northern Gulf of Mexico
F.T. Manheim, J. L. Bischoff
1969, Chemical Geology (4) 63-82
Pore waters were analyzed from 6 holes drilled from M.V. “Eureka” as a part of the Shell Oil Co. deeper offshore study. The holes were drilled in water depths of 600–3,000 ft. (approximately 180–550 m) and penetrated up to 1,000 ft. (300 m) of Pliocene-Recent clayey sediments. Salt and...
Ion association in natural brines
A.H. Truesdell, B.F. Jones
1969, Chemical Geology (4) 51-62
Natural brines, both surface and subsurface, are highly associated aqueous solutions. Ion complexes in brines may be ion pairs in which the cation remains fully hydrated and the bond between the ions is essentially electrostatic, or coordination complexes in which one or more of the hydration water molecules are...
Chemical composition of selected Kansas brines as an aid to interpreting change in water chemistry with depth
R.J. Dingman, E.E. Angino
1969, Chemical Geology (4) 325-339
Chemical analyses of approximately 1,881 samples of water from selected Kansas brines define the variations of water chemistry with depth and aquifer age. The most concentrated brines are found in the Permian rocks which occupy the intermediate section of the geologic column of this area. Salinity decreases below the...
Surface area of vermiculite with nitrogen and carbon dioxide as adsorbates
Josephus Thomas Jr., Bruce F. Bohor
1969, Clays and Clay Minerals (17) 205-209
Surface-area studies were made on several homoionic vermiculites with both nitrogen and carbon dioxide as adsorbates. These studies show that only very slight penetration occurs between individual vermiculite platelets. This is in contrast to an earlier investigation of montmorillonite where it was found that the degree of penetration between layers...

R.D. Hyndman, J.C. Jaeger, J.H. Sass
1969, Earth and Planetary Science Letters (7) 12-16
Three boreholes have been drilled for the Australian National University near the southeast coast of New South Wales, Australia. The heat flows found are 1.1, 1.0, and 1.3 μcal/cm2sec. The errors resulting from the proximity of the sea and a lake, surface...

Walter E. Parham
1969, Clays and Clay Minerals (17) 13-22
Weathering products formed on surfaces of both potassium and plagioclase feldspar (An70), which were continuously leached in a Soxhlet extraction apparatus for 140 days with 7.21 of distilled water per day at a temperature of approximately 78°C, are morphologically identical to natural products developed on potassium feldspars weathered under conditions...

Leonard Gene Schultz
1969, Clays and Clay Minerals (17) 115-149
X-ray analysis of Li+- and K+-saturated samples, differential thermal analysis (DTA), thermal gravimetric analysis (TGA), and chemical analysis of 83 samples enable a distinction to be made between Wyoming, Tatatilla, Otay, Chambers, and non-ideal types of montmorillonite, and between ideal and non-ideal types of beidellite. The Greene-Kelly Li+-test differentiates between...
