Sporomorphs And Palynological Interpretations Of Lower Oligocene Strata From The Eastern Gulf Coast, U.S.A., Lisa M. Reeves
Sporomorphs And Palynological Interpretations Of Lower Oligocene Strata From The Eastern Gulf Coast, U.S.A., Lisa M. Reeves
Opportunities for Undergraduate Research Experience Program (OURE)
The Vicksburg Group in the eastern Gulf Coast of the United States belongs to one of the most complete and continuous Paleogene strata in the world. Previous studies in this region have neglected the rich palynomorph assemblages of the Lower Oligocene units of the Vicksburg Group. Four samples from Wayne County Mississippi were analyzed for palynological information on the Vicksburg Group. The initial objective of the study was to understand the principles of palynology and the basis for sporomorph identification. A minimum of 300 specimens were counted per slide to determine the distribution of sporomorphs in the sediments. Two hundred …
Dolomite Cement Stratigraphy Of The Reelfoot Rift And The Relationship Of These Cements To Dolomite Cements Found In Southeast Missouri, Timothy James Keller
Dolomite Cement Stratigraphy Of The Reelfoot Rift And The Relationship Of These Cements To Dolomite Cements Found In Southeast Missouri, Timothy James Keller

The formation of the southeast Missouri Mississippi Valley-type Pb, Zn, Cu ore districts have been a subject of controversy. Using petrology and geochemistry, earlier studies have attempted to reveal fluid flow, composition, and origin of the ore forming fluids. In this study, the potential role of the Reelfoot rift (New Madrid seismic zone) as a source and/or conduit for ore forming fluids is addressed. By observing cuttings and cores from four oil test wells within the Reelfoot rift using cathodluminescence, four cement types were described: 1) A multiple generation cement type similar to that observed associated with mineralization in southeastern …
Depositional Facies Analysis And Sea Level Curve Determination From The Soth Western St. Francois Mts. To The Western Margin Of The Reelfoot Rift, Missouri, Aaron Ramon Rezendez

Knowledge of the relative influence of eustatic and tectonic controls on sedimentation in basins is important to developing a regional facies model. The Reelfoot Rift basin is located on the southern margin of the North American Craton. The tectonic and sedimentary history of the rift began during Middle Cambrian time and extended through the Early Ordovician. Oil test well cuttings and cores were used to construct a stratigraphic fence extending from the Cambro- Ordovician platform west of the St. Francois Mts. southeastward info the rifted basin. Three major transgressive-regressive sequences and numerous minor transgressive-regressive sequences were observed in Cambro-Ordovician rocks …
Influence Of The Mcdowell Sanitary Landfill On Groundwater Quality, Phelps County, Missouri, Christine E. Bough
Influence Of The Mcdowell Sanitary Landfill On Groundwater Quality, Phelps County, Missouri, Christine E. Bough
Opportunities for Undergraduate Research Experience Program (OURE)
This is a case study of the groundwater quality near the McDowell Sanitary Landfill in Phelps County, Missouri. The landfill is located in section 21 of T37N R8W off of Missouri State Highway CC. This landfill is a near surface solid waste disposal facility above the groundwater table located in an abandoned area of a rock quarry. The thickness, lithology, and structure of the material beneath the landfill, and the design of the landfill itself, will influence the time of contaminant transport and degree of modification in the event that leachate escapes the landfill. Among the more important topographic features …
