The geochemistry of groundwater and sediments governing tungsten concentration in the basin-fill aquifers, Fallon, Nevada
… to understand the geochemical cycle of W in the basin-fill aquifer. Tungsten in the groundwater became a potential health concern due to its observed concentrations in the human population of Fallon; the potential sources of W from nearby W ore deposits, mines, processing plants, and geothermal …

The evolution of a sand-rich basin-fill sequence in the Pendleian (Namurian,E1c)of North-West England
The Bowland and Lancaster Fells Basins of north-west England contain a Pendleian El, sequence up to 650m thick, most of which is coarse clastic material. Each of the major stratigraphic units in this sequence, namely the Pendle and Grassington Grit Groups, represents a phase of clastic input to the …

Hydrochemical facies study of ground water in the Tucson Basin
… of the chemical character of ground water in the basin-fill aquifer of the Tucson Basin in relationship to the hydrogeologic framework. Hydrochemical fades of ground water is defined operationally in terms of the lateral (horizontal) variation of chemical quality. The following chemical …

Stratigraphic Architecture and Paleogeography of the Juniata Formation, Central Appalachians
… of both tectonics and eustasy within a foreland-basin setting. The Juniata Formation consists of red sandstones, siltstones, and shales that were deposited as part of an extensive siliciclastic basin-fill that resulted from the Taconic Orogeny. This study attempts to resolve some of the questions …

Stratigraphy, Structure, and Fluid Flow at the Soda Lake Geothermal Field, western Nevada, USA
… lies in the southern part of the Carson Sink basin of northwestern Nevada within the Basin and Range of the western USA. The Basin and Range is a world-class geothermal province with significant untapped potential, particularly in blind (no surface hot springs or steam vents) geothermal …

Numerical Modeling as a Means to Enhance Genetic Sedimentary Basin Interpretation : A Case Study of the Southern Cantabrian Basin (NW Spain)
… the development of the Southern Cantabrian Basin (NW Spain). A sedimentological and sequence stratigraphic model was established for the syn-orogenic Carboniferous basin fill, and subsequently analyzed and calibrated by a combined approach of reverse basin and stratigraphic forward …

Determination of coefficient of storage by use of gravity measurements.
… The study area is located in the northern Tucson basin, Pima County, Arizona, and lies on unconfined basin-fill deposits and flood-plain alluvium aquifers. The basin-fill aquifer overlies less permeable Rillito beds and is overlain by the flood-plain alluvium. The two upper aquifers are …

Age, Stratigraphy and Depositional Environment of the Pliocene Copper Canyon Formation, Death Valley, California
… and bird tracks. The formation represents a basin fill sequence consisting of approximately 1800 m of conglomerates, basalt flows, and lacustrine deposits. A measured type section along with x-ray diffraction, isotopic analysis, and thin section petrography shows an evolution of the ancient …

Depositional history of the Black Mountain conglomerate, Mohave County, Arizona: Sedimentary response to Miocene extension
… Arizona. The field area, part of the Basin and Range province, lies within an area that experienced northward migration of intense volcanism several million years prior to significant regional extension. Extension propagated northward through the northern Colorado River extensional …

Stratigraphy, sedimentology, and paleotectonic setting of the Gazelle Formation, eastern Klamath Mountains, northern California
… Gazelle Formation was deposited as trench-slope basin fill. This interpretation is consistent with the regional tectonic framework and the fact that the characteristics of the Gazelle Formation match those of modern and ancient trench-slope basins worldwide.

Tectonic and sedimentary history of the Mid-Natal Valley (S.W. Indian Ocean)
The Natal Valley is a sediment-filled marine basin situated between the east coast of southern Africa (Natal) and the Mozambique Ridge. Geophysical and sedimentological techniques are used in a broad geological study of the mid Natal Valley. Major emphasis is directed to: (a) basin history and …

Submarine channelforms and fans in the Miocene Moki and Mount Messenger formations, Taranaki Basin, New Zealand
Taranaki Basin (New Zealand) contains a Late Cretaceous – Cenozoic sedimentary succession up to 9 kilometres thick. Neogene strata are volumetrically a significant part of the basin fill. During the late-Middle Miocene a new sediment source, arising from the onset of uplift and erosion of the …

FORAMINIFERAL DISTRIBUTION AND SEQUENCE STRATIGRAPHY OF OXFORDIAN SUCCESSIONS IN THE WESSEX/ANGLO-PARIS BASIN
… a more accurate picture of the controls on basin fill than can be provided by sedimentology alone. It has demonstrated the importance of the preservation upon the fossil assemblages recovered and how this can influence the establishment of biozones.

Early cretaceous belemnites from Southern India
The Cauvery Basin has been the subject of intense research into the bio- and lithostratigraphies of the basin fill since Blanford and Stoliczka (1861-65). The Karai Formation ranges from the Early Albian through to the late Turonian in age. The belemnites in this study were collected from the …
