New evidence for a Pliocene marine embayment along the lower Colorado River area, California and Arizona
Patsy Beckstead Smith
1970, Bulletin of the Geological Society of America (81) 1411-1420
Marine foraminiferal, marine to fresh-water molluscan, and brackish- to fresh-water ostracode faunas occur in a thick section of limestone, silt, and clay of the Bouse Formation along the Colorado River from Parker to Yuma in an area now isolated from the sea. Faunas in the Parker-Blythe-Cibola area are limited in...

Premetamorphic down-to-basin faulting, folding, and tectonic dewatering, Rangeley area, western Maine
Robert H. Moench
1970, Bulletin of the Geological Society of America (81) 1463-1496
The Rangeley area of western Maine is underlain by a thick sequence of dominantly eugeosynclinal metasedimentary rocks of Ordovician, Silurian, and Devonian age. The dominant structural pattern of these rocks is defined by tight, upright, northeast-trending passive flow folds and by three major normal faults along which younger rocks on...
Peru-Chile Trench sediments and sea-floor spreading
David W. Scholl, Mark N. Christensen, Roland E. von Huene, Michael S. Marlow
1970, Bulletin of the Geological Society of America (81) 1339-1360
The hypotheses of sea-floor spreading and plate tectonics require the removal of sediment from oceanic trenches either by crustal underthrusting or by folding against the base of a continental or insular margin. Accordingly, over a period of time the volume of sediment removed by way of spreading must be equal...
Macusanite occurrence, age, and composition, Macusani, Peru
Virgil E. Barnes, George Edwards, W. A. McLaughlin, Irving Friedman, Oiva Joensuu
1970, Bulletin of the Geological Society of America (81) 1539-1546
Macusanite, originally believed to be a type of tektite because of its sculpture, is shown to be related to sillar of the Macusani region, Peru. K-Ar measurements establish identical Pliocene ages (4.2 m.y.) for macusanite and sillar and relate these deposits to the extensive ash...

Role of gravity, temperature gradients, and ion exchange media in the formation of fossil brines
P. C. Mangelsdorf Jr., Frank T. Manheim, J. M. Gieskes
1970, American Association of Petroleum Geologists Bulletin (54) 617-626
Calculations show that gravitational settling of ions in an isothermal sediment column could produce increases of equilibrium concentrations in pore waters ranging from 1 percent per 100 m depth for chloride to 4 percent per 100 m depth for strontium.The migration of ions in a thermal gradient (Soret effect) would...

Arsenic in detergents: Possible danger and pollution hazard
E.E. Angino, L.M. Magnuson, T.C. Waugh, O.K. Galle, J. Bredfeldt
1970, Science (168) 389-390
Arsenic at a concentration of 10 to 70 parts per million has been detected in several common presoaks and household detergents. Arsenic values of 2 to 8 parts per billion have been measured in the Kansas River. These concentrations are close to the amount (10 parts per billion) recommended by...
Geological significance of coccoliths in fine-grained carbonate bands of postglacial Black Sea sediments
David Bukry, Stanley A. King, Michael K. Horn, Frank T. Manheim
1970, Nature (226) 156-158
The origin of fine carbonate muds in deep parts of the Black Sea has been explained in various ways, but details of how the carbonate was formed are poorly understood. We have studied samples containing fine carbonate from cores obtained during the cruise of Atlantis II (Woods Hole Oceanographic Institute)...
Missile impacts as sources of seismic energy on the moon
G.V. Latham, W.G. McDonald, H. J. Moore
1970, Science (168) 242-245
Seismic signals recorded from impacts of missiles at the White Sands Missile Range are radically different from the signal recorded from the Apollo 12 lunar module impact. This implies that lunar structure to depths of at least 10 to 20 kilometers is quite different from the typical structure of the...
Age determination of raccoons
G.A. Grau, G.C. Sanderson, J.P. Rogers
1970, Journal of Wildlife Management (34) 364-372
Age criteria, based on 61 skulls and eye lenses from 103 known-age captives, are described for separating raccoons (Procyon lotor) into eight age-classes as follows: young-of-the-year, 1, 2, 3, 4, 5, 6-7, > 7 years. Criteria studied were eye lens nitrogen, cranial suture closure, tooth wear and incisor cementum layers....
Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 3
F.T. Manheim, K.M. Chan, D. Kerr, W. Sunda
1970, Initial reports of the Deep Sea Drilling Project (3) 663-666
Eleven samples of fluids which had been squeezed on board ship, and four, packaged sediment samples were received in our laboratories. As in Leg 2, the volumes of fluid available were scanty and did not permit multiple determinations of constituents in many of the samples; in Hole 21 the fluid...
Faulting in the Burro Mountain area, California Coast Ranges, and its relation to the Nacimiento fault
Robert Ahlberg Loney
1970, Bulletin of the Geological Society of America (81) 1249-1254
The northwest-striking Nacimiento fault, in the southern Coast Ranges of California, has generally been regarded as the boundary between two major structural blocks: the Nacimiento block to the southwest, in which the basement rocks belong to the Franciscan Formation (Upper Jurassic to Upper Cretaceous), and...
Studies of hydrothermal gold deposition (I). Carlin gold deposit, Nevada: The role of carbonaceous materials in gold deposition
Arthur S. Radtke, Bernard J. Scheiner
1970, Economic Geology (65) 87-102
Studies of fresh carbonate host rocks and unoxidized gold ores of the Carlin mine indicate that gold, quartz, barite, pyrite, and other sulfides were introduced into the Roberts Mountains Formation by acid hydrothermal solutions. Laboratory investigations on the carbonaceous materials in the host rocks and...
Comparative hydrogeology: An example of its use
Harry E. LeGrand
1970, Bulletin of the Geological Society of America (81) 1243-1248
As a start toward needed classifications of hydrogeologic settings, a type of setting is described. The setting includes areas where soluble materials are exposed to considerable recharge from precipitation and where both the topographic relief and permeability are inappreciable. Typical areas of this setting are (1) the Black Belt of...
Green River oil shale—concept of origin extended: An interdisciplinary problem being attacked from both ends
W. H. Bradley
1970, GSA Bulletin (81) 985-1000
A much fuller understanding of the Green River oil shale and its organic chemistry will emerge when the geologists, paleontologists, organic chemists, biologists, paleolimnologists, and biogeochemists, who are now working on it, integrate their findings with those of the others.We know from the geology, paleontology, and paleolimnology that the biologic...

Observations of iceberg rafting in Glacier Bay, Alaska, and the identification of ancient ice-rafted deposits
A. Thomas Ovenshine
1970, Bulletin of the Geological Society of America (81) 891-894
Observations of icebergs in a modern glacial marine environment indicate that ancient rocks that received iceberg-rafted material should contain: (1) local concentrations of stones that originated when icebergs overturned, and (2) small pellets of till that were originally sediment filling the spaces between clear ice crystals.The till pellets are especially...
