The geochemical and magnetic record of coal combustion products in West Virginia reservoir sediments and soils The geochemical and magnetic record of coal combustion products in West Virginia reservoir sediments and soils
Western West Virginia lies downwind from numerous coal-fired power plants along the Ohio River Valley. To test whether geochemical and mineralogical impacts from these power plants are detectable on the West Virginia landscape, we obtained reservoir cores, soils, and rocks from two separate sites in West Virginia, one in Harrison County (Hinkel and Deegan Reservoirs) and the other in...

Reply to discussion on “Tectonic controls of Mississippi Valley-type lead–zinc mineralization in orogenic forelands” Reply to discussion on “Tectonic controls of Mississippi Valley-type lead–zinc mineralization in orogenic forelands”
Bradley and Leach (2003) focused on the tectonics of a subset of Mississippi Valley-type (MVT) lead–zinc deposits. Age assignments followed those given in a review of MVT deposits worldwide (Leach et al. 2001)—a paper that provoked a discussion by Kesler and Carrigan (2002) and reply by Leach et al. (2002), similar to the present exchange. While the new discussion by Kesler et al. (2004)...

Record of late Pleistocene glaciation and deglaciation in the southern Cascade Range: II. Flux of glacial flour in a sediment core from Upper Klamath Lake, Oregon Record of late Pleistocene glaciation and deglaciation in the southern Cascade Range: II. Flux of glacial flour in a sediment core from Upper Klamath Lake, Oregon
During the late Wisconsin, glacial flour from alpine glaciers along the east side of the Cascade Range in southern Oregon was deposited in Upper Klamath Lake. Quantitative interpretation of magnetic properties and grain-size data of cored sediments from Caledonia Marsh on the west side of the lake provides a continuous record of the flux of glacial flour spanning the last ≈37 000...

Limits of mountain and continental glaciations east of the Continental Divide in northern Montana and north-western North Dakota, U.S.A. Limits of mountain and continental glaciations east of the Continental Divide in northern Montana and north-western North Dakota, U.S.A.
This chapter provides an overview of the limits of glaciations and glacial history in, and east and south-east of, Glacier National Park, Montana, and on the Northern Plains further east in Montana and north-western North Dakota. The term “Laurentide glacier” was applied to a continental ice sheet east of the Rocky Mountains in North America. It describes Laurentide Ice Sheet as any...

Uranium-series coral ages from the US Atlantic Coastal Plain-the "80 ka problem" revisited Uranium-series coral ages from the US Atlantic Coastal Plain-the "80 ka problem" revisited
Uranium series coral ages for emergent units from the passive continental margin US Atlantic Coastal Plain (ACP) suggest sea level above present levels at the end of marine oxygen isotope stage (MIS) 5, contradicting age-elevation relations based on marine isotopic or coral reef models of ice equivalent sea level. We have reexamined this problem by obtaining high precision 230Th/238U and...

Vital signs monitoring plan for the Klamath Network: Phase I report Vital signs monitoring plan for the Klamath Network: Phase I report
This report chronicles the Phase 1 stage of the vital signs monitoring program for the Klamath Network. It consists of two chapters and eleven appendixes. The purposes of Chapter One are to 1) describe the network administrative structure and approach to planning; 2) introduce the Klamath Network parks, their resources, and environmental settings; 3) explain the need for monitoring...

Late Quaternary stratigraphy and geochronology of the western Killpecker Dunes, Wyoming, USA Late Quaternary stratigraphy and geochronology of the western Killpecker Dunes, Wyoming, USA
New stratigraphic and geochronologic data from the Killpecker Dunes in southwestern Wyoming facilitate a more precise understanding of the dune field's history. Prior investigations suggested that evidence for late Pleistocene eolian activity in the dune field was lacking. However, luminescence ages from eolian sand of ???15,000 yr, as well as Folsom (12,950-11,950 cal yr B.P.) and Agate...
