A high 87Sr 86Sr mantle source for low alkali tholeiite, northern Great Basin
R. K. Mark, Hu C. Lee, H. R. Bowman, F. Asaro, E.H. McKee, R.R. Coats
1975, Geochimica et Cosmochimica Acta (39) 1671-1678
Olivine tholeiites, the youngest Tertiary units (about 8–11 m.y. old) at five widely spaced localities in northeastern Nevada, are geologically related to the basalts of the Snake River Plain, Idaho, to the north and are similar in major element and alkali chemistry to mid-ocean ridge basalts (MORB) and island arc...
Sandrewia, n. gen., a problematical plant from the Lower Permian of Texas and Kansas
S.H. Mamay
1975, Review of Palaeobotany and Palynology (20) 75-83
Sandrewia, n. gen., monotypified by S. texana, n. sp., is a plant from Lower Permian beds of north-central Texas and east-central Kansas. It is characterized by stout axes with spirally disposed, laxly inserted, petiolate leaves; the laminae are broadly flabelliform with coarse, open venation....
Trace element evaluation of a suite of rocks from Reunion Island, Indian Ocean
R. A. Zielinski
1975, Geochimica et Cosmochimica Acta (39) 713-734
Reunion Island consists of an olivine-basalt shield capped by a series of flows and intrusives ranging from hawaiite through trachyte. Eleven rocks representing the total compositional sequence have been analyzed for U, Th and REE. Eight of the rocks (group 1) have positive-slope, parallel, chondrite-normalized REE fractionation patterns. Using a...
Hydrologic data of the coastal drainage basins of southeastern Massachusetts, Weir River, Hingham, to Jonas River, Kingston
John R. Williams, Richard E. Willey, Gary D. Tasker
1975, Massachusetts Hydrologic - Data Report 16
The principal basins are those of Weir River, James Brook, Bound Brook, North River, South River, and Jones River, all draining to Massachusetts Bay and Cape Cod Bay. These basins are bounded on the north by the Weymouth River basins, on the west by the Taunton River basin, and on...
Residue dynamics of quinaldine and TFM in rainbow trout
J. B. Hunn, J. L. Allen
1975, General Pharmacology (6) 15-18
Study of the residue dynamics of 2-methylquinoline (quinaldine) and 3-trifluoromethyl-4-nitrophenol (TFM) in rainbow trout yielded the following findings:1. Uptake and distribution of TFM by trout was influenced by the biotransformation of the lipidsoluble free phenol. No such effect was observed with quinaldine.2. Disappearance of quinaldine and TFM from gallbladder bile...
Calculated geochronology and stress field orientations along the Hawaiian chain
E.D. Jackson, H. R. Shaw, K.E. Bargar
1975, Earth and Planetary Science Letters (26) 145-155
A new method has been discovered for calculating ages of the main shield building stages of volcanoes along the Hawaiian chain from Kilauea to the Hawaiian-Emperor bend. The method is based on a graphical technique for hypothetical subtraction of distance intervals that...
Improved digital filters for evaluating Fourier and Hankel transform integrals
Walter L. Anderson
1975, Report
New algorithms are described for evaluating Fourier (cosine, sine) and Hankel (J0,J1) transform integrals by means of digital filters. The filters have been designed with extended lengths so that a variable convolution operation can be applied to a large class of integral transforms having the same...
Age of amphibolites associated with alpine peridotites in the Dinaride ophiolite zone, Yugoslavia
M. A. Lanphere, R. G. Coleman, S. Karamata, J. Pamic
1975, Earth and Planetary Science Letters (26) 271-276
Amphibolites associated with alpine peridotites in the Central Ophiolite zone in Yugoslavia have K-Ar ages of 160–170 m.y. These amphibolites and associated peridotites underwent deep-seated metamorphism prior to tectonic emplacement into the sedimentary-volcanic assemblage of the Dinarides. The alpine peridotites and associated...
The determination of specific forms of aluminum in natural water
R.B. Barnes
1975, Chemical Geology (15) 177-191
A procedure for analysis and pretreatment of natural-water samples to determine very low concentrations of Al is described which distinguishes the rapidly reacting equilibrium species from the metastable or slowly reacting macro ions and colloidal suspended material. Aluminum is complexed with 8-hydroxyquinoline (oxine), pH is adjusted to 8.3 to...
Short chain aliphatic acid anions in oil field waters and their contribution to the measured alkalinity
L.M. Willey, Y.K. Kharaka, T. S. Presser, J. B. Rapp, I. Barnes
1975, Geochimica et Cosmochimica Acta (39) 1707-1711
High alkalinity values found in some formation waters from Kettleman North Dome oil field are due chiefly to acetate and propionate ions, with some contribution from higher molecular weight organic acid ions. Some of these waters contain no detectable bicarbonate alkalinity. For waters...
The new Martian nomenclature of the international Astronomical Union
Vaucouleur G. de, J. Blunck, M. Davies, A. Dollfus, I.K. Koval, G. P. Kuiper, H. Masursky, S. Miyamoto, V.I. Moroz, C. Sagan, B. Smith
1975, Icarus (26) 85-98
A new nomenclature for Martian regions and topographic features uncovered by Mariner 9, as officially adopted by the International Astronomical Union, is described. About 180 craters, generally of diameters >100 km, have been named, as well as 13 classes of topographic...
Thin-section electron microscopy of mature Myxosoma cerebralis (Myxosporidea) spores
P.D. Lunger, B.L. Rhoads, K. Wolf, M.E. Markiw
1975, Journal of Parasitology (61) 476-480
The morphology of purified, mature Myxosoma cerebralis spores was examined by thin-section electron microscopy. Surface architecture corresponded closely to that described in an earlier scanning electron microscopy study of this organism (Lom and Hoffman, 1971). A uniformly thick spore wall is composed of finely granular, electron-lucent material. Intrawall "valvoplasm" at...
Dynamics of turbidity plumes in Lake Ontario
Edward J. Pluhowski
1975, Open-File Report 75-249
Large-turbidity features along the 275-kilometre long south shore of Lake Ontario were analyzed using LANDSAT-1 images. The ESIAC system developed by the Stanford Research Institute, was used to obtain enlargements and false-color renditions of turbidity plumes. After projection on a video screen, individual turbidity features were analyzed, mapped, and photographed.The...
