The Distribution Of Several Metals And Cation Exchange Capacity In Sediment Fractions From An Artificial And Natural Marsh, James River, Virginia, William Nivens

OES Theses and Dissertations

In order to examine the mechanisms by which Fe, Mn, Ca, Zn, Cu, Ni and Pb are bound in sediments, a sequential selective extraction procedure was employed on sediment samples collected at an experimental dredge disposal marsh and a neighboring natural marsh located near Windmill Point, James River, Va. The metal concentrations were determined in six phases, interstitial water, exchangeable, easily reducible (oxides of Mn), organic, moderately, reducible (oxides of Fe), and residual fractions. In addition, the cation exchange capacity (CEC) of the sediments was determined as well as the actual role of organics and colloidal iron coatings as they …

Stratigraphy, Sedimentary Petrology, And Depositional Environments Of Tillite In The Upper Precambrian Mount Rogers Formation, Virginia, Richard L. Rexroad

LSU Historical Dissertations and Theses

The upper member of the upper Precambrian Mount Rogers Formation of southwestern Virginia includes thick units of massive conglomeratic mudstone Interpreted as tillite (Rankin, 1970; Blondeau and Lowe, 1972; Blondeau, 1975; Schwab, 1976). The tillite is composed of unsorted angular plutonic, metamorphic, volcanic, and sedimentary rock fragments enclosed within a matrix of sandy hematitic mudstone. The tillite is interbedded with arkosic sandstone, argillite, and conglomerate. Sedimentary structures and textures of these units suggest deposition by glaciers which protruded from land into a standing body of water as floating ice. Glacial drift was deposited in a large body of water, probably …

Geology Of The Lucea Inlier, Western Jamaica, Jack Grippi

Geology Theses and Dissertations

The Lucea Inlier exposes a Santonian to Campanian 4 km + thick sequence of shale-siltstone, resedimented volcaniclastics, lenses of shallow-water limestone, micritic limestone, pebbly mudstone and sandy pebble to boulder conglomerate. Clastics were deposited by a variety of gravity flow mechanisms. Petrographically sandstones are lithic or feldspathic arenites and contain only very small amounts of detrital quartz. Structurally the inlier is characterized by simple, open, east-west trending folds. A spaced, vertical axial-planar cleavage is developed in shales and fine siltstones. Two major east-west trending left-lateral fault zones, the Fat Hog Quarter and Maryland faults, cut the inlier into three blocks, …

The Petrology And Stratigraphy Of The Portland Hills Silt, Rodney Thomas Lentz

Dissertations and Theses

Topics in geology, which inevitably excite professional discussion and even tempered debate, often present challenging targets for the exploratory jabs of Master's degree candidates. The Portland Hills Silt and the controversy concerning its genesis provides just such an object.

Although the physical descriptions of the silt are generally in agreement, they remain somewhat generalized and, at present, no single definition is generally accepted. Moreover, incongruities concerning structural and textural details--notably, the presence of minor stratification and/or scattered pebbles in the silt--have resulted in considerable disagreement regarding its mode of origin.

Nebraska Mineral Operations Review, 1976, Raymond R. Burchett, Duane A. Eversoll

Conservation and Survey Division: Faculty and Staff Publications

During 1976, there were active in Nebraska 41 limestone quarries; 592 sand, gravel and silt or siltstone pits; 8 clay or shale pits; 24 sandstone pits; and 1 peat pit. These 666 mining operations disturbed 820 acres and restored 78 acres during the year.

Water Resources Data For Nebraska Water Year 1976

Conservation and Survey Division: Faculty and Staff Publications

Water resources data for the 1976 water year for Nebraska consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for 146 gaging stations; stage and contents for 9 lakes and reservoirs; water quality for 40 gaging stations, 18 ungaged stations, 27 partial-record flow stations, and 96 wells; and water levels for 66 observation wells. Also included are 114 crest-stage partial-record stations and 12 low-flow partialrecord stations. Additional water data were collected at various sites, not part …

Petrology Of The Rockport Quarry Limestone (Middle Devonian Traverse Group) Alpena, Presque Isle And Montmorency Counties, Michigan, Charles Willard Cookman

Masters Theses

The basal unit of the dominantly carbonate Traverse Group, the Bell Shale, is gradationally overlain by the Rockport Quarry Limestone which has a thickness of approximately 14 m. The Rockport Quarry Limestone is composed of a dark unrestricted marine subtidal organic-mud packstone facies, comprised of an algal-mat-bearing coral packstone subfacies and a shallower water crinoid-bryozoan grainstone subfacies; a shoal forming stromatoporoid biolithite facies; and a lagoonal micrite facies comprised of a subtidal dense subfacies containing gastropods, ostracods, and calcispheres, and an Intertidal to supratidal fenestral subfacies. The local facies tract reconstructed for the Rockport Quarry Limestone is interpreted to be …
