Post-middle Miocene accretion of Franciscan rocks, northwestern California.
R. J. McLaughlin, S.A. Kling, R.Z. Poore, K. McDougall, E.C. Beutner
1982, Geological Society of America Bulletin (93) 595-605
Deformed sedimentary rocks assigned to the Franciscan assemblage in the King Range S of Cape Mendocino, N California, are dominantly deep-water argillite and sandstone occurring as thick- to thin-bedded, locally channelized marine turbidities of arkosic to andesitic volcaniclastic composition. The King Range appears to be a displaced terrane of oceanic...
Cyclic deposits and hummocky cross-stratification of probable storm origins in Upper Cretaceous rocks of the Cape Sebastian area, southwestern Oregon
R. E. Hunter, H. Clifton
1982, Journal of Sedimentary Petrology (52) 127-143
Cyclic deposits containing hummocky cross-stratification occur in the upper part of the Cape Sebastian Sandstone of Bourgeois (1980), a shallow marine transgressive sandstone of Late Cetaceous age on the southern Oregon coast. The cycles average 1.6 m in thickness and consist, where complete,...
Techniques for using iron crucibles in experimental igneous petrology.
C.R. Thornber, J.S. Huebner
1982, American Mineralogist (67) 1144-1154
Some iron crucibles contain impurities of Mn, Ti and other elements. Such impurities may alter the fO2 of the system and induce crucible-charge interactions. Pretreatment of impure iron crucibles in a CO2-CO atmosphere at 1050oC, under conditions slightly more reducing than Fe-Fe1-xO, minimizes undesirable changes in the bulk composition of...
USGS aerial resolution targets.
P.H. Salamonowicz
1982, Photogrammetric Engineering and Remote Sensing (48) 1469-1473
It is necessary to measure the achievable resolution of any airborne sensor that is to be used for metric purposes. Laboratory calibration facilities may be inadequate or inappropriate for determining the resolution of non-photographic sensors such as optical-mechanical scanners, television imaging tubes, and linear arrays. However, large target arrays imaged...

Nesting of waterfowl on islands in Lake Audubon, North Dakota
Harold F. Duebbert
1982, Wildlife Society Bulletin (10) 232-237
Nesting waterfowl were studied in 1978 and 1980 on 15 newly established islands with an area of 19 ha in 7,430-ha Lake Audubon in the Audubon National Wildlife Refuge (NWR), North Dakota. Islands ranged in size from 0.2 to 5.0 ha and were 60-1,600 m from the mainland. Cover available...
Refining Landsat classification results using digital terrain data
Wayne A. Miller, Mark Shasby
1982, Journal of Applied Photographic Engineering (8) 35-40
Scientists at the U.S. Geological Survey's Earth Resources Observation systems (EROS) Data Center have recently completed two land-cover mapping projects in which digital terrain data were used to refine Landsat classification results. Digital ter rain data were incorporated into the Landsat classification process using two different procedures that required developing...

Landsat classification accuracy assessment procedures
R. R. Mead, John Szajgin
1982, Photogrammetric Engineering and Remote Sensing (48) 139-141
A working conference was held in Sioux Falls, South Dakota, 12-14 November, 1980 dealing with Landsat classification Accuracy Assessment Procedures. Thirteen formal presentations were made on three general topics: (1) sampling procedures, (2) statistical analysis techniques, and (3) examples of projects which included accuracy assessment and the associated costs, logistical...
Geology and sediment accumulation rates at Carrie Bow Cay, Belize

Klaus Ruetzler, Ian G. Macintyre, editor(s)
1982, Smithsonian Contributions to the Marine Sciences 12
A 24 km long transect of cores consisting of four rotary drill cores and seven vibrocores was drilled in a line extending from the seaward side of the reef crest at Carrie Bow Cay to the mainland at a point between Sittee Point and the town of Stann Creek. Two...
Assessment of models proposed for the 1981 revision of the IGRF
N.W. Peddie, E.B. Fabiano
1982, Journal of Geomagnetism & Geoelectricity (34) 387-392
For the second revision of the International Geomagnetic Reference Field (IGRF), the U. S. National Aeronautics and Space Administration (NASA), the U. K. Institute of Geological Sciences (IGS), and the U. S. Geological Survey (USGS) submitted proposed models of the Earth's main magnetic field at 1965.0, 1970.0, 1975.0, and 1980.0,...
International Geomagnetic Reference Field
N.W. Peddie

In August 1981 the International Association of Geomagnetism and Aeronomy revised the International Geomagnetic Reference Field (IGRF). It is the second revision since the inception of the IGRF in 1968. The revision extends the earlier series of IGRF models from 1980 to 1985, introduces a new series of...

Notes. Characterization of plutonium in ground water near the idaho chemical processing plant
Jess M. Cleveland, Terry F. Rees
1982, Environmental Science and Technology (16) 437-439
Plutonium is present in very low concentrations in ground water near the disposal well at the Idaho Chemical Processing Plant but was not detected in waters at greater distances. Because of the absence of strong complexing agents, the plutonium is present as an uncomplexed (perhaps hydrolyzed) tetravalent species, which is...
