F.L. Sayles, Frank T. Manheim
1971, Initial reports of the Deep Sea Drilling Project (7) 871-881
The sediments cored on Leg 7 are predominantly deep sea biogenic oozes and chalks; only rarely were significant quantities of pelagic clays and volcanic detritus encountered. The biogenic sections include both siliceous and calcareous deposits. At three sites the drilling terminated in basalt, one of which (Site 62) is interpreted...
Sedimentary and gravity-slide emplacement of serpentinite
J. P. Lockwood
1971, Bulletin of the Geological Society of America (82) 919-936
Large deposits of serpentinite in alpine-type orogenic areas have been formed by sedimentary processes ranging from the detrital accumulation of bedded serpentinite sandstone and shale to the emplacement of chaotic breccias (olistostromes) and gigantic slide blocks. Known occurrences of sedimentary serpentinite are listed, and eight deposits from the circum-Pacific, Caribbean,...

Reconnaissance of the Pigeon River, a cold-water river in the northcentral part of Michigan's southern peninsula
G. E. Hendrickson, C. J. Doonan
1970, Hydrologic Atlas 333
The cold-water streams of the northern states provide unique recreational values to the American people (wilderness or semi-wilderness atmosphere, fast-water canoeing, and trout fishing), but the expanding recreational needs must be balanced against the growing demand of water for public and industrial supplies, for irrigation, and for the dilution of...
Economic geology of the Zipaquira quadrangle and adjoining area, Department of Cundinamarca, Colombia
Donald H. McLaughlin Jr., Marino Arce Herrera
1970, Open-File Report 70-208
At least four evaporite sequences are interbedded with Cretaceous strata in the Bogotga area of the Cordillera Oriental of Colombia. The easternmost and oldest evaporite interval is of probable Berriasian-Valanglnian age; the next oldest is of probable late Barremian-early Aptian age, and is followed by a possible late Aptian sequence....

Seismic activity in the Sunnyside mining district, Carbon and Emery Counties, Utah, during 1968
C. Richard Dunrud, John O. Maberry, Jerome H. Hernandez
1970, Open-File Report 70-115
More than 20,000 local earth tremors were recorded by the seismic monitoring network in the Sunnyside mining district during 1968. This is about 40 percent of the number of tremors recorded by the network in 1967. In 1968 a total of 281 tremors were of sufficient magnitude to be located...
Boulder Creek batholith, Colorado part I: Allanite and its bearing upon age patterns
Nelson L. Hickling, George Phair, Roosevelt Moore, Harry J. Rose Jr.
1970, Bulletin of the Geological Society of America (81) 1973-1993
Allanite is abundant and commonly attains unusually large size as a late-replacement mineral in: (1) the comagnatic rocks of the Precambrian Boulder Creek batholith; (2) associated amphibolite xenoliths and related hybrid rocks; and (3) distinctly younger intrusions of Silver Plume Granite that cut the complex. Allanite porphyroblasts develop by replacement...
A hermaphroditic coregonine from Lake Michigan
Thomas A. Edsall
1970, Transactions of the American Fisheries Society (99) 611 p.
Hermaphroditism is relatively rare among the Salmonidae (See Atz, 1964 for a comprehensive review) and has never been reported for coregonine fishes. Recent examination of a collection of coregonines at the Great Lakes Fishery Laboratory disclosed a hermaphroditic bloater(Coregonus hoyi). The fish was captured in a gill net...
Effects of alewife predation on zooplankton populations in Lake Michigan
LaRue Wells
1970, Limnology and Oceanography (15) 556-565
The zooplankton populations in southeastern Lake Michigan underwent striking, size-related changes between 1954 and 1966. Forms that decline sharply were the largest cladocerans (Leptodora kindtii, Daphnia galeata, and D. retrocurva), the largest calanoid copepods (Limnocalanus macrurus, Epischura lacustris, and Diaptomus sicilis), and the largest cyclopoid copepod (Mesocyclops edax). Two of...

Throughout most of northern Arizona the Redwall Limestone of Mississippian age is readily divisible into four lithologic units, designated in ascending order as the Whitmore Wash, Thunder Springs, Mooney Falls, and Horseshoe Mesa Members. The first and third members are thick-bedded to massive carbonate rock. The Horseshoe Mesa Member is...
The benthic macrofauna of Lake Ontario
Jarl K. Hiltunen
1969, Technical Report 14
The presence and relative abundance of bottom macrofauna in Lake Ontario are documented. Bottom samples were collected at 24 stations in September 1964. The quantity of organisms and the distribution of some species were affected by depth of water. Samples from the shallower stations (47.5 m or less) yielded an...
Magnetic susceptibility and exchange coupling in the mineral ardennite
A. N. Thorpe, F. E. Senftle, G. Donnay
1969, Journal of Physics and Chemistry of Solids (30) 2235-2239
Ardennite, a rare silicate mineral, contains about 19 wt.% manganese. Some of the manganese atoms are in positions which are close enough to allow negative exchange and hence a reduction of the total magnetic susceptibility. It is shown that the susceptibility can be accounted for approximately by the treatment of...
The relationship of the rare-earth composition of minerals to geological environment
M. Fleischer, Z. S. Altschuler
1969, Geochimica et Cosmochimica Acta (33) 725-732
It has been known for a long time that the composition of the lanthanides in minerals is controlled to a large degree by crystallo-chemical factors, but is also greatly influenced by changes in geological environment. In general, igneous rocks rich in silica are favourable for the concentration of the heavy...
