Comparison of species composition and richness of fish assemblages in altered and unaltered littoral habitats
T.P. Poe, C.O. Hatcher, C. L. Brown, D. W. Schloesser
1986, Journal of Freshwater Ecology (3) 525-536
Species composition and richness of fish assemblages in altered and unaltered littoral habitats in Lake St. Clair, Michigan, differed between areas. A percid-cyprinid-cyprinodontid assemblage dominated in the unaltered area, Muscamoot Bay, which has a natural shoreline (with almost no alteration due to dredging or bulkheading), high water quality, and high...

Effects of shrub coverages on birds of North Dakota mixed-grass prairies
T.W. Arnold, K.F. Higgins
1986, Canadian Field-Naturalist (100) 10-14
We studied the distribution and density of passerine birds in relation to Wolfberry (Symphoricarpos occidentalis) and Silverberry (Elaeagnus commutata) shrub coverages on mixed-grass prairies of central North Dakota. Birds were counted along shrubby and shrubless transects during the 1982 breeding season. Species richness and total density of birds were greater...
Paleodrainages of the Eastern Sahara-The radar rivers revisited (SIR-A/B Implications for a Mid-Tertiary Trans-Afnrcan Drainage System)

1986, IEEE Transactions on Geoscience and Remote Sensing (GE-24) 624-648
A complex history of Cenozoic fluvial activity in the presently hyperarid Eastern Sahara is inferred from SIR data and postflight field investigations in southwest Egypt and northwest Sudan. SIR images were coregistered with Landsat and existing maps as a guide to exploration of the buried paleodrainages (radar rivers) first discovered...

Distribution of anomalously high K2O volcanic rocks in Arizona: metasomatism at the Picacho Peak detachment fault
W. E. Brooks
1986, Geology (14) 339-342
Metasomatized Tertiary lavas with anomalously high K2O and low Na2O content are distributed within the northwest-trending Miocene extensional terrane of southwestern Arizona. These rocks are common near core-complex–related detachment faults at Picacho Peak and the Harcuvar Mountains and in listric-faulted terrane at the...
A ground-water mixing model for the origin of the Imini manganese deposit (Cretaceous) of Morocco
E. R. Force, W. Back, E.C. Spiker, L.P. Knauth
1986, Economic Geology (81) 65-79
Three beds of manganese oxide ore in a 10 m-thick dolomite unit are associated with diagenetic features, and, are accordingly also diagenetic in their present aspect. Whether primary or introduced, the Mn mineralogy is attributed to reactions between fresh and saline ground-waters as the zone of mixing passed through the...
EVIDENCE FOR THREE MODERATE TO LARGE PREHISTORIC HOLOCENE EARTHQUAKES NEAR CHARLESTON, S. C.
Robert E. Weems, Stephen F. Obermeier, Milan J. Pavich, Gregory S. Gohn, Meyer Rubin, Richard L. Phipps, Robert B. Jacobson
1986, Conference Paper
Earthquake-induced liquefaction features (sand blows), found near Hollywood, S. C. , have yielded abundant clasts of humate-impregnated sand and sparse pieces of wood. Radiocarbon ages for the humate and wood provide sufficient control on the timing of the earthquakes that produced the sand blows to indicate that at least three...
Application of seismic refraction methods in groundwater modeling studies in New England (USA)
F.P. Haeni
1986, Geophysics (51) 236-249
Seismic refraction studies were conducted over unconfined glacial aquifers in New England to determine: 1) depth of the underlying bedrock; 2) depth of the water table; 3) saturated thickness of the aquifer in areas not accessible to heavy drilling equipment; 4) areas where thick, unsaturated sediments overlie thickly saturated parts...

Geochemical correlation of surface and subsurface oils, western Greece
J. G. Palacas, D. Monopolis, C.A. Nicolaou, D.E. Anders
1986, Organic Geochemistry (10) 417-423
Biodegraded seep oils, devoid of n-alkanes and most isoprenoid hydrocarbons, were successfully correlated with subsurface crude oils in western Greece primarily using carbon isotopes and the more microbially resistant tricyclic terpane and aromatic steroid hydrocarbon distributions. All the studied oils seem to fit into three major genetic groups which are...
Temperature effects on kerogen and on molecular and isotopic composition of organic matter in Pierre Shale near an igneous dike
J.L. Clayton, N. H. Bostick
1986, Organic Geochemistry (10) 135-143
A suite of siltstone samples from the Upper Cretaceous Pierre Shale from the contact zone of a 130-cm thick igneous dike near Wolcott, Colorado, U.S.A., was taken from the contact to 170 cm from the dike to study the effects of temperature on the organic matter. The sampled bedding interval...
Phase relations in the CuVS system
D. Wu, L.L.Y. Chang, C.R. Knowles
1986, Journal of the Less-Common Metals (115) 243-251
Phase relations in the system Cu-V-S were studied by using a sealedcapsule technique, reflected-light microscopy, X-ray powder diffraction and electron microprobe analysis. In the temperature range between 300 and 900 ??C, six vanadium sulfides exist in the V-S system. These are VS, V7S8, V3S4, V5S8, V3S5 and VS4. In the...
Selective chemical dissolution of sulfides: An evaluation of six methods applicable to assaying sulfide-bound nickel
P.R. Klock, G.K. Czamanske, M. Foose, J. Pesek
1986, Chemical Geology (54) 157-162
Six analytical techniques for the selective chemical dissolution of sulfides are compared with the purpose of defining the best method for accurately determining the concentration of sulfide-bound nickel. Synthesized sulfide phases of known elemental content, mixed with well-analyzed silicates, were used to determine the relative and absolute efficiency, based on...

Oil-source correlation study in northeastern Alaska
D.E. Anders, Leslie B. Magoon
1986, Organic Geochemistry (10) 407-415
The occurrence of numerous oil-stained outcrops across the coastal plain of the Arctic National Wildlife Refuge (ANWR) in northeastern Alaska indicates that commercial hydrocarbons could be present in the subsurface of this region. In addition, this region is flanked by two important oil provinces—the Prudhoe Bay area to the west...
Nature of phases synthesized along the join (Mg,Mn)2Si2O6.
J.S. Huebner
1986, American Mineralogist (71) 111-122
Eight compositions were synthesized along this join. Orthopyroxene crystallized at X = Mn/(Mn + Mg) = 0.0-0.3, clinopyroxene at X 0.4-0.5, and pyroxmangite at X 0.65-1.0, consistent with the composition ranges that have been inferred by examination of metamorphic rock assemblages. Unit-cell dimensions for these phases and for rhodonite (X...
Archaeological prospection: An introduction to the Special Issue
Jeffrey C. Wynn
1986, Geophysics (51) 533-537
Archaeological prospection, as the use of geophysical methods in archaeology is known in Europe, is about four decades old (seven decades, if aerial photography of archaeological sites is included). Virtually the entire range of geophysical methods, perhaps excluding only borehole techniques, has found application in the search for archaeological sites...

The South Fork detachment fault, Park County, Wyoming: discussion and reply ( USA).
W. G. Pierce
1986, Contributions to Geology - University of Wyoming, Laramie (24) 77-90
Blackstone (1985) published an interpretation of South form detachment fault and related features. His interpretation of the area between Castle and Hardpan transverse faults is identical to mine of 1941. Subsequent detailed mapping has shown that the structure between the transverse faults is more complicated than originally envisioned and resurrected...

1986, American Mineralogist (71) 406-427
Several layered pegmatite-aplite intrusives exposed at the Little Three mine, Ramona, display closely associated fine-grained to giant-textured mineral assemblages which are believed to have co-evolved from a hydrous aluminosilicate residual melt with an exsolved supercritical vapour phase. Calculations of phase relations between the major pegmatite-aplite mineral assemblages and supercritical aqueous...
