The system Cu-Ag-S
Brian J. Skinner
1966, Economic Geology (61) 1-26
Compositions on the join Cu 2 S-Ag 2 S were studied with X-ray diffractometer heating stage. Low-temperature phases, which break down at temperatures between 67 degrees and 119 degrees C, are chalcocite, stromeyerite, Cu (sub O.8) Ag (sub 1.2) S, jalpaite, and acanthite. High-temperature phases, all cation-disordered, are hexagonal close-packed (high chalcocite), face-centered cubic...

Hawaiian Volcano Observatory record book 1960, 1965, and 1966
1966, Report
The Hawaiian Volcano Observatory (HVO) record books are annual journals in which field observations of eruptive activity at Kīlauea and Mauna Loa volcanoes, on the Island of Hawaiʻi, were compiled by HVO staff for most years from 1912 through early 1966. In addition to descriptive observations, the record books also...

Waste injection into a deep limestone in northwestern Florida
J.T. Barraclough
1966, Groundwater (4) 22-24
During a three-month trial period, 70 million gallons of industrial wastes were successfully injected at moderate pressures into a deep limestone in the westernmost part of Florida. The movement of these wastes is expected to be predominantly southward toward the natural discharge area which is presumed to be far out...
Some blood chemistry values for five Chesapeake Bay area fishes
J. B. Hunn, P.F. Robinson
1966, Chesapeake Science (7) 173-175
Blood samples from gizzard shad,largemouth bass, white perch, pumpkinseed, and toadfish were analyzed for hemoglobin, total plasma protein, total plasma cholesterol, and ion concentrations of plasma sodium, potassium, and chloride. The hemoglobin concentration and total plasma cholesterol found in a given species seem to have positive correlation with the customary activity level...

Leveling

Geodetic leveling by the U.S. Geological Survey provides a framework of accurate elevations for topographic mapping. Elevations are referred to the Sea Level Datum of 1929....
The 1963–65 eruption of Irazú volcano, Costa Rica (the period of March 1963 to October 1964)
K. J. Murata, C. Dondoli, R. Saenz
1966, Bulletin Volcanologique (29) 763-793
The 1963–65 eruption of Irazú, like all others of this volcano during the historic period, produced only ash and other fragmental ejecta without lava. The initial outbreak on March 13, 1963 started with a series of great explosions that hurled out much ash, blocks, and bombs, but the activity...

Observed variations in the strontium concentration of sea water
E.E. Angino, G.K. Billings, N. Andersen
1966, Chemical Geology (1) 145-153
On samples obtained from five widely separated areas of the North Atlantic Ocean 91 determinations of strontium were made. These include surface and deep-water samples from both the cold North Atlantic area and the warm subtropical Caribbean area. The results differ from...
Composition and evolution of the continental crust as suggested by seismic observations
L. C. Pakiser, R. Robinson
1966, Tectonophysics (3) 547-557
The average composition of the continental crust is more mafic than hitherto supposed. The conterminous United States can be divided, on the basis of seismic structure, into ten regions. The seven western and the three eastern regions can be termed western and eastern...
Disequilibrium of the 238U series in basalt
B.L.K. Somayajulu, M. Tatsumoto, J.N. Rosholt, R. J. Knight
1966, Earth and Planetary Science Letters (1) 387-391
Radioisotope analyses of basalt samples from Hawaii, Japan, and Iwo Jima show that: (1)234U and238U are virtually in radioactive equilibrium, (2)230Th exceeds equilibrium values in all these samples, (3)210Pb concentrations range from 10–200% of the equilibrium values and average 30% deficient, and...
Effects of weathering on the UPb ages of zircon from the Morton Gneiss, Minnesota
T. W. Stern, S. S. Goldich, M. F. Newell
1966, Earth and Planetary Science Letters (1) 369-371
Weathering has caused large losses of lead from the zircon in the residual clay derived from the Morton Gneiss of southwestern Minnesota, drastically reducing the 206Pb/238U and the 207Pb/235U ages. The 207Pb/206Pb age probably has not been significantly affected. Loss of lead by leaching during weathering has not been adequately...
Mineral exploration and soil analysis using in situ neutron activation
F. E. Senftle, A.F. Hoyte
1966, Nuclear Instruments and Methods (42) 93-103
A feasibility study has been made to operate by remote control an unshielded portable positive-ion accelerator type neutron source to induce activities in the ground or rock by “in situ” neutron irradiation. Selective activation techniques make it possible to detect some thirty or...
Some alkali and titania analyses of tektites before and after G-1 precision monitoring
D.B. Tatlock
1966, Geochimica et Cosmochimica Acta (30) 123-128
A comparison of 55 older analyses of Australasian tektites with 110 modern precisely monitored analyses suggests that more than half of the older alkali and titania determinations are decidedly inaccurate and misleading. Deviations of the older analyses from the restricted values of the...
