Sedimentary volumes and their significance
James Gilluly, John C. Reed Jr., Wallace M. Cady
1970, Bulletin of the Geological Society of America (81) 353-375
Sedimentary volumes are of prime interest in many fields of geology: as measures of erosional rates, of geochemical balance, and recently, with the virtual demonstration of continental drift, as measures of movement of the continental and oceanic plates.The Basement Map of the United States, published by the U.S. Geological Survey...
Nuclear methods applied to uranium geochemistry
J. N. Rosholt
1970, IEEE Transactions on Nuclear Science (17) 173-176
Stable and radioactive daughter products produced from nuclear disintegrations of uranium have proved useful in fundamental studies of the geochemistry of uranium in igneous rock and sedimentary environments and in ore deposits. Information gained from geochemical studies of uranium migration has been used to develop models...
Specific heats of lunar surface materials from 90 to 350 degrees Kelvin
R. A. Robie, B. S. Hemingway, W.H. Wilson
1970, Science (167) 749-750
The specific heats of lunar samples 10057 and 10084 returned by the Apollo 11 mission have been measured between 90 and 350 degrees Kelvin by use of an adiabatic calorimeter. The samples are representative of type A vesicular basalt-like rocks and of finely divided lunar soil. The...
Lunar rock compositions and some interpretations
A.E.J. Engel, C.G. Engel
1970, Science (167) 527-528
Samples of igneous "gabbro," "basalt," and lunar regolith have compositions fundamentally different from all meteorites and terrestrial basalts. The lunar rocks are anhydrous and without ferric iron. Amounts of titanium as high as 7 weight percent suggest either extreme fractionation of lunar rocks or an unexpected solar abundance of titanium....
Lunar troilite: Crystallography
H. T. Evans Jr.
1970, Science (167) 621-623
Fine, euhedral crystals of troilite from lunar sample 10050 show a hexagonal habit consistent with the high-temperature NiAs-type structure. Complete three-dimensional counter intensity data have been measured and used to confirm and refine Bertaut's proposed low-temperature crystal structure....
Thermoluminescence of lunar samples
G. B. Dalrymple, Richard R. Doell
1970, Science (167) 713-715
Appreciable natural thermoluminescence with glow curve peaks at about 350 degrees centigrade for lunar fines and breccias and above 400 degrees centigrade for crystalline rocks has been recognized in lunar samples. Plagioclase has been identified as the principal carrier of thermoluminescence, and the difference in peak temperatures indicates compositional or...
Age of the moon: An isotopic study of uranium-thorium-lead systematics of lunar samples
M. Tatsumoto, J.N. Rosholt
1970, Science (167) 461-463
Concentrations of U, Th, and Pb in Apollo 11 samples studied are low (U. 0.16 to 0.87; Th, 0.53 to 3.4; Pb, 0.29 to 1.7, in ppm) but the extremely radiogenic lead in samples allows radiometric dating. The fine dust and the breccia have a concordant age...
Lunar soil: Size distribution and mineralogical constituents
M.B. Duke, C.C. Woo, M. L. Bird, G.A. Sellers, R. B. Finkelman
1970, Science (167) 648-650
The lunar soil collected by Apollo 11 consists primarily of submillimeter material and is finer in grain size than soil previously recorded photographically by Surveyor experiments. The main constituents are fine-grained to glassy rocks of basaltic affinity and coherent breccia of undetermined origin. Dark glass, containing abundant nickel-iron spheres, coats...
Petrology of unshocked crystalline rocks and shock effects in lunar rocks and minerals
E. C. T. Chao, O.B. James, J.A. Minkin, J.A. Boreman, E.D. Jackson, C.B. Raleigh
1970, Science (167) 644-647
On the basis of rock modes, textures, and mineralogy, unshocked crystalline rocks are classified into a dominant ilmenite-rich suite (subdivided into intersertal, ophitic, and hornfels types) and a subordinate feldspar-rich suite (subdivided into poikilitic and granular types). Weakly to moderately shocked rocks show high strain-rate deformation and solid-state transformation of...
Emission spectrographic determination of trace elements in lunar samples
C. Annell, A. Helz
1970, Science (167) 521-523
Eighteen minor or trace elements were detected and determined by emission spectroscopy. Direct d-c arc excitation of powdered samples was used with three variations in the procedure. Thirteen lunar samples consisting of four fine-grained igneous rocks, one medium-grained igneous rock, seven breccias, and one sample of fines were analyzed. The...
Crystallography of some lunar plagioclases
D. B. Stewart, D.E. Appleman, J.S. Huebner, J. R. Clark
1970, Science (167) 634-635
Crystals of calcic bytownite from type B rocks have space group I1 with c ≈ 14 angstroms. Bytownite crystals from type A rocks...
Suspended matter in surface waters of the Atlantic continental margin from Cape Cod to the Florida Keys
F.T. Manheim, R.H. Meade, G. C. Bond
1970, Science (167) 371-376
Appreciable amounts of suspended matter (> 1.0 milligram per liter) in surface waters are restricted to within a few kilometers of the Atlantic coast. Particles that escape estuaries or are discharged by rivers into the shelf region tend to travel longshoreward rather than seaward. Suspended matter farther offshore, chiefly amorphous...

Paul J. Sorvo
1970, Names (18) 185-190
In the early hours of March 30, 1867, Secretary of State William H. Seward completed the purchase of the remote and unexplored land known as Russian America, or Alaska. Discovered in 1741 by Vitus Bering, Alaska progressed from a Czarist colony to a territory of the United States, and finally,...

Estimating steady-state evaporation rates from bare soils under conditions of high water table
C.D. Ripple, J. Rubin, T. E. A. Van Hylckama
1970, Report
A procedure that combines meteorological and soil equations of water transfer makes it possible to estimate approximately the steady-state evaporation from bare soils under conditions of high water table. Field data required include soil-water retention curves, water table depth and a record of air temperature, air humidity and wind velocity...
