G.L. Storm, G.J. Fosmire, E.D. Bellis
1994, Journal of Environmental Quality (23) 508-514
Concentration of Cd, Pb, Zn, and Cu in soil and wildlife at the Palmerton zinc smelter site in eastern Pennsylvania were determined 6 yr after zinc smelting was terminated in 1980. Levels of the four metals were higher in litter (01 and 02 horizon) than in soil (A1 horizon), and...
High-precision 40Ar/39Ar age spectrum dating of sanidine from the Middle Pennsylvanian Fire Clay tonstein of the Appalachian basin
Michael J. Kunk, Charles L. Rice
1994, GSA Special Papers (294) 105-112
40Ar/39Ar plateau age spectra of seven sanidine samples from the Fire Clay tonstein (Middle Pennsylvanian), collected along a 300-km traverse in the Appalachian basin, range from 310.3 to 311.4 Ma. All plateau ages agree, within the limits of analytical precision, with their respective total gas ages. This agreement, together with...
40Ar/39Ar chronology and volcanology of silicic volcanism in the Davis Mountains, Trans-Pecos Texas
Christopher D. Henry, Michael J. Kunk, W. C. McIntosh
1994, GSA Bulletin (106) 1359-1376
Field studies and 40Ar/39Ar dating reveal that silicic volcanism in the Davis Mountains part of the Trans-Pecos Texas volcanic field occurred in six episodes at 0.3 m.y. intervals between 36.8 and 35.3 Ma. Additionally, two groups of silicic intrusions were emplaced at 34.6 and 32.8 Ma. This episodicity is similar to...
40Ar 39Ar age constraints on neogene sedimentary beds, Upper Ramparts, half-way Pillar and Canyon village sites, Porcupine river, east-central Alaska
Michael J. Kunk, H. Rieck, T. D. Fouch, L. David Carter
1994, Quaternary International (22-23) 31-42
40Ar/39Ar ages of volcanic rocks are used to provide numerical constraints on the age of middle and upper Miocene sedimentary strata collected along the Porcupine River. Intercalated sedimentary rocks north of latitude 67°10′N in the Porcupine terrane of east-central Alaska contain a rich record of plant fossils. The fossils are valuable...

C. L. Rice, Harvey E. Belkin, T.W. Henry, R. E. Zartman, Michael J. Kunk
1994, GSA Special Papers (294) 87-104
The Middle Pennsylvanian Fire Clay tonstein, mostly kaolinite and minor accessory minerals, is an altered and lithified volcanic ash preserved as a thin, isochronous layer associated with the Fire Clay coal bed. Seven samples of the tonstein, taken along a 300-km traverse of the central Appalachian basin, contain cogenetic phenocrysts...
Predators of the Whitetail
Daniel B. Fagre
1994, Book chapter, Deer
white-tailed deer have long been important prey for large predators. Before Europeans colonized North America, deer roaming the forested region east of the Great Plains and areas along the Gulf of Mexico were hunted by wolves and mountain lions, and by Native Americans for food and clothing materials. Today, wolves...

Correlation and age of the Upper Jurassic Morrison Formation from magnetostratigraphic analysis
Maureen B. Steiner, S. G. Lucas, Eugene Merle Shoemaker
Mario V. Caputo, James A. Peterson, Karen J. Franczyk, editor(s)
1994, Book chapter, Mesozoic systems of the Rocky Mountain region, USA, 1994
The magnetostratigraphy of the Morrison Formation of east-central New Mexico resembles that of three western Colorado sections. Magnetic polarity and lithology agree among the sections, indicating the correlation potential of magnetostratigraphy in this lithologically complex formation. Both magnetostratigraphy, lithology, and paleopoles divide the formation into two parts. The lower...

Late winter survival of female mallards in Arkansas
Bruce D. Dugger, Kenneth J. Reinecke, Leigh H. Fredrickson
1994, Journal of Wildlife Management (58) 94-99
Determining factors that limit winter survival of waterfowl is necessary to develop effective management plans. We radiomarked immature and adult female mallards (Anas platyrhynchos) after the 1988 and 1989 hunting seasons in eastcentral Arkansas to test whether natural mortality sources and habitat conditions during late winter limit seasonal survival. We...

1994, Quaternary Science Reviews (13) 879-890
The deglacial history of the Lake Michigan basin, including discharge and routing of meltwater, is complex because of the interaction among (1) glacial retreats and re-advances in the basin (2) the timing of occupation and the isostatic adjustment of lake outlets and (3) the depositional and erosional processes that left...

J. T. Dugan, T. J. McGrath, R. B. Zelt
1994, Water-Resources Investigations Report 94-4027
Changes in water levels in the High Plains aquifet underlying parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming result from the variability of precipitation, land use, and ground-water withdrawals. From the beginning of development of the High Plains aquifer to 1980, water levels declined throughout...

The geologic framework of southern Lake Michigan
D.S. Foster, D. W. Folger
1994, Journal of Great Lakes Research (20) 44-60
The bathymetry is controlled by the underlying bedrock. Bedrock comprises Silurian dolomite and Devonian limestone and shale. Quaternary sediment, 10 to 40 m thick, overlies bedrock. From Waukegan, Illinois, south to Indiana Harbor, the bottom is floored by till, sand, pebbles, and cobbvles. The lake floor is erosional or nondepositional...

Two episodes of meltwater influx from glacial Lake Agassiz into the Lake Michigan basin and their climatic contrasts
Steven M. Colman, L.D. Keigwin, R. M. Forester
1994, Geology (22) 547-550
Two episodes of meltwater influx from glacial Lake Agassiz are recorded as prominent sedimentologic, isotopic, magnetic, and faunal signatures in southern Lake Michigan profundal sediments. As a tributary to the main path of eastward Lake Agassiz flow, southern Lake Michigan recorded only the largest, catastrophic discharges. The distinctive Wilmette Bed,...

In the Altamont-Bluebell Petroleum Field within the Uinta Basin of Utah, saline oil-production water is being injected into the Duchesne River Formation. On the basis of geohydrologic information, a qualitative assessment of the possible effects of this injection indicates that fresh groundwater in certain areas of the Duchesne River formation...
Volcanic gas emissions and their impact on ambient air character at Kilauea Volcano, Hawaii
A. J. Sutton, T. Elias, R. Navarrete
1994, Open-File Report 94-569
Currently, gas emissions from Kilauea occur from the summit caldera, along the middle East Rift Zone (ERZ), and where lava enters the ocean. We estimate that the current ERZ eruption of Kilauea releases between 400 metric tonnes of SO2 per day, during eruptive pauses, to as much as 1850 metric...
Atmospheric circulation and snowpack in the Gunnison River Basin
Gregory J. McCabe
1994, Conference Paper, Proceedings of the 21st Annual Conference on Water Policy and
Winter mean 700-millibar height anomalies over the eastern North Pacific Ocean and the western United States are related to variability in snowpack accumulations measured on or about April 1 in the Gunnison River Basin in Colorado. Higher-than-average snowpack accumulations are associated with negative 700-millibar height anomalies (anomalous cyclonic circulation) over...
