Interstitial water studies on small core samples, leg 19
F.L. Sayles, L.S. Waterman, Frank T. Manheim
1973, Initial reports of the Deep Sea Drilling Project (19) 871-874
The sediments cored on Leg 19 consist primarily of diatomaceous oozes with variable proportions of volcanic material and terrigenous clays and silts. With a few exceptions, deposition rates are high at these sites, usually exceeding 5cm/103y. The interstitial solutions sampled exhibit compositional changes which previously have been found to characterize...

W. G. Pierce, W. H. Nelson
1973, Geological Society of America Bulletin (84) 2631-2644
The Crandall Conglomerate (Eocene) is a channel deposit, more than 350 ft (100 m) thick, believed to have formed as a result of preliminary movement of the Heart Mountain detachment fault in northwestern Wyoming. Initial movement of the Heart Mountain fault opened a deep rift in which the conglomerate was...
Phosphate in interstitial waters of anoxic sediments: Oxidation effects during sampling procedure
J.T. Bray, O.P. Bricker, B.N. Troup
1973, Science (180) 1362-1364
Oxidation during sampling procedures significantly decreases the inorganic phosphate concentrations of interstitial water rich in iron (II). All sampling and analytical procedures must be carried out in an inert atmosphere. Orthophosphate in the interstitial water of Cheaspeake Bay sediments, in equilibrium with vivianite, is a potential nutrient source for the...

Apollo 17 landed in a deep graben valley embaying the mountainous highlands southeast of the Serenitatis basin. Impact-generated breccias underlie the massifs adjacent to the valley, and basalt has flooded and leveled the valley floor. The dark mantle inferred from orbital photographs was not recognized as a discrete unit; the...
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...

Chemical variation related to the stratigraphy of the Columbia River basalt
Thomas L. Wright, Maurice J. Grolier, Don Swanson
1973, GSA Bulletin (84) 371-386
Study of major element chemical analyses of Columbia River basalt leads to a grouping of most of the analyses into 11 chemical types which are distinguished with little overlap on a SiO2-MgO variation diagram. Other diagnostic variation diagrams are total iron (‘FeO’)-MgO, K2O-MgO, and TiO2-MgO.A four-unit informal stratigraphy has been...
Magma Mixing as Illustrated by the 1959 Eruption, Kilauea Volcano, Hawaii
Thomas L. Wright
1973, GSA Bulletin (84) 849-858
The 1959 eruption of Kilauea volcano is unique among recent Kilauea summit eruptions (1952 to 1968) in at least two respects: (1) a large collapse of Kilauea summit accompanied the eruption, and (2) the erupted lavas show a complex variation in their bulk chemical composition. Both features suggest that the...
Point Mugu, California, earthquake of 21 February 1973 and its aftershocks
W.L. Ellsworth, R. H. Campbell, D.P. Hill, R.A. Page, R. W. Alewine III, Thomas C. Hanks, T. H. Heaton, J.A. Hileman, H. Kanamori, B. Minster, J.H. Whitcomb
1973, Science (182) 1127-1129
Seismological investigations show that the Point Mugu earthquake involved north-south crustal shortening deep within the complex fault zone that marks the southern front of the Transverse Ranges province. This earthquake sequence results from the same stress system responsible for the deformation in this province in the Pliocene through Holocene and...
Gravity measurements in the vicinity of Georges Bank
John D. Hendricks, James D. Robb
1973, Geological Society of America Bulletin (84) 3911-3916
A total of 97 new bottom gravity measurements on the continental shelf in the vicinity of Georges Bank was reduced to the simple Bouguer anomaly, using a density of 2.80 gm per cm3 for the correction. Results help substantiate the presence of mafic and felsic intrusive bodies along the northern...
Reinterpretation of the boundary between the Cosumnes and Logtown Ridge Formations, Amador County, California
Robert V. Sharp, Wendell A. Duffield
1973, Geological Society of America Bulletin (84) 3969-3976
Recent detailed geologic mapping in the Sierran foothills reveals that rocks previously included in the Jurassic Amador Group must be redefined. The term “Amador Group” was applied by Taliaferro and Clark to a section of epiclastic metasedimentary rocks (the Cosumnes Formation) and the seemingly conformable overlying metavolcanic rocks (the Logtown...
Interstitial water studies on small core samples, Leg 15
Fred L. Sayles, Frank T. Manheim, Lee S. Waterman
1973, Initial reports of the Deep Sea Drilling Project (15) 783-804
Analyses of pore fluids from reducing environments demonstrate that reduction of SO4 is accompanied by large increases in alkalinity and strong depletion of Ca and Mg. The data are compatible with a model of replacement of Fe3+ in clay lattices by Mg from the interstitial solutions and the precipitation of...

1973, Geology (1) 187-189
Pearlette family volcanic ash beds at two faunally important late Cenozoic localities near Meade, Meade County, Kansas, are very similar in chemical and mineralogic composition, yet their zircon microphenocrysts have markedly different fission-track ages. Zircon microphenocrysts from type B Pearlette volcanic ash underlying sediments that contain the Borchers local fauna...
Annealing history limits for inhomogeneous, native gold grains as determined from Au-Ag diffusion rates
Gerald K. Czamanske, George A. Desborough, Fraser E. Goff
1973, Economic Geology (68) 1275-1288
Quantitative study of intrinsic inhomogeneities in native gold grains from three deposits in the western United States has revealed concentration profiles that represent the integrated sum of natural diffusion plus original chemical heterogeneity. By assuming that measured natural concentration gradients result solely from diffusion, upper limits may be placed on...
Geologic factors affecting compaction of deposits in a land-subsidence area
William B. Bull
1973, Geological Society of America Bulletin (84) 3783-3802
In the west-central San Joaquin Valley, California, pumping of ground water has changed water levels, thereby increasing the stresses that tend to compact alluvium by as much as 50 percent and creating a large area of intense land subsidence.The estimated 1943–1960 specific unit compaction (compaction during a time period, per...
Stress of formalin treatment in juvenile spring chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Salmo gairdneri>)
Gary Wedemeyer, W. T. Yasutake
1973, Journal of the Fisheries Research Board of Canada (31) 179-184
The physiological stress of 200 ppm formalin treatments at 10 C is more severe in the juvenile steelhead trout (Salmo gairdneri) than in the spring chinook salmon (Oncorhynchus tshawytscha). In the steelhead, a marked hypochloremia follows a 1-hr treatment and recovery requires about 24 hr. During longer treatments, hypercholesterolemia together with reduced...
Radiometric ages of Kodiak Seamount and Giacomini Guyot, Gulf of Alaska: Implications for Circum-Pacific tectonics
D. L. Turner, R. B. Forbes, Charles W. Naeser
1973, Science (182) 579-581
Kodiak Seamount and Giacomini Guyot have been dated at 22.6 ± 1.1 and 19.9 ± 1.0 [2σ (standard deviation)] × 106 years, respectively. Concordant whole-rock and plagioclase potassium-argon dates and fission-track apatite ages demonstrate that significant quantities of excess radiogenic 40Ar are not present in the dated samples. These...
Westward tidal lag as the driving force of plate tectonics
George W. Moore
1973, Geology (1) 99-100
As spreading at known interarc basins occurs to the west of westward-dipping subduction zones, and movement of the lower plates is also to the west, it is suggested that all plates move chiefly westward. Rates of motion are equal to a net difference between eastward and westward transport on semidiurnal...
