A Seismic Analysis Of Reefs In The Traverse Limestone Of Allegan County, Michigan, William Charles Henderson

Masters Theses

A seismic reflection study was performed across the Diamond Springs oil field in Allegan County, Michigan. The horizon of interest was the Middle Devonian Traverse Limestone located 1,700 feet in the subsurface. Within the Traverse Limestone are scattered patch reefs which characterize a targeted reservoir. The use of high-resolution, shallow seismic reflection techniques are useful for defining detailed subsurface porosity zones within the patch reef reservoirs.

Common source-offset profiling utilizing high-frequency sources and proper determination of field parameters are important in obtaining the desired optimum reflection. Also, the use of synthetic seismograms for modeling waveforms is essential for identifying the …

Geometry And Kinematics Of The Central Snowcrest Range: A Rocky Mountain Forehand Uplift In Southwestern Montana, Barry Christopher Mcbride

Masters Theses

The Snowcrest Range forms the southeastern limb of the Late Cretaceous Blacktail-Snowcrest uplift. The northeast-trending uplift is bounded by the northwest-dipping Snowcrast-Greenhom thrust system which consists of seven thrust zones which merge and flatten at depth along a regional detachment horizon within the Archean basement.

The structures forming the Snowcrest Range are concave westward with trends varying from N 55° E in the southern region to north-south in the northern region. Calcite twin lamellae and fracture orientations indicate that the principal shortening direction was oriented S 85° E during late Cretaceous time. This orientation requires that a significant component of …

Fission-Track Geochronology And Geothermometry Of Late Cretaceous-Early Tertiary Epizonal Plutons, In And Adjacent To The Lombard Thrust Fault, Southwestern Montana, Jean Talanda

Masters Theses

Thrusting occurred in the central portion of the central Montana salient where the timing of movements is somewhat obscured by the multiple deformations from Archean time to the present. The relationship of this thrusting to the associated plutons has not been established in every case. Fission-track geochronology was employed in dating several plutons associated with the Lombard thrust fault, consequently, defining a time range in which movement along the thrust occured.

Seven plutons with known structural relationships to the Lombard thrust have ages which suggest that movement along the fault occurred 73.2 +/- 6.7 Ma. Fission-track length distributions suggest that …

Electrical Resistivity As An Approach To Evaluating Brine Contamination Of Groundwater In The Walker Oil Field, Ottawa County, Michigan, Janet A. Koehler

Masters Theses

Surface electrical resistivity successfully defined brine contamination within a glacial drift aquifer in western Michigan. The study site is in a residential area of eastern Ottawa County, in the Walker Oil Field. A Schlumberger array with a maximum current electrode separation (AB/2) of 316 meters (1037 feet) was used. It was possible to detect geoelectric layers to about 30 meters (100 feet) below ground level, with the maximum current penetration of about 1/10 (AB/2). On occasion, thick surficial clay precluded detecting deeper geoelectric layers. Through use of the INVERS computer program, fifty vertical electrical soundings were interpreted and correlated with …

An Investigation Of A Soil Gas Sampling Technique And Its Applicability For Detecting Gaseous Pce And Tca Over An Unconfined Granular Aquifer, Timothy J. Mayotte

Masters Theses

A soil gas sampling and analytical technique was investigated to evaluate its ability and versatility for detecting chlorinated hydrocarbons in unconfined aquifers. The technique was used successfully to delineate plumes of perchloroethene (PCE), and 1,1,1-trichloroethane (TCA) contamination present in the vadose zone, and at the water table of an unconfined sand and gravel aquifer. Soil gas samples were obtained by concentrating PCE and TCA vapors diffusing from these sources onto a sorbent material. The samples were analyzed by gas chromatography. The data from the analysis of these samples were used to provide an initial estimate of the source areas, and …

The Significance Of Organic Complexing In The Mobility Of Iron In The Kl Landfill Leachate Plume, Kalamazoo, Michigan, James D. Rudder

Masters Theses

High iron concentrations in the leachate plume of the KL Landfill in Kalamazoo County, Michigan, persist in the presence of detectable hydrogen-sulfide. Under these conditions iron-sulfide minerals are highly oversaturated and should be precipitating. Calculations performed by the chemical equilibrium model WATEQF indicate over-saturation of selected iron-oxides, siderite, and iron-sulfides. Semilog plots of iron concentration versus time of exposure to air demonstrate retarded precipitation of ferric hydroxide, and analytical techniques of ion chromatography, Fourier transform IR spectrophotometry (FTIR), and UV-Visible spectrophotometry have yielded results which indicate that organic complexing of ferrous iron plays a significant role in the mobility of …

Feasibility Of The Proposed Garden Lane Recharge Basin In Portage, Michigan, Sandra K. Barnick

Masters Theses

The purpose of this study was to evaluate the potential effectiveness of proposed artificial recharge basins at the Garden Lane Well Field in Portage, Michigan. The area is underlain by 7 feet of muck, 27 feet of sand and gravel, and a 10 foot semiconfining till over a semiconfined aquifer.

The vertical permeability of the semiconfining layer, and the hydraulic head difference between the upper unconfined aquifer and the lower semiconfined aquifer were determined. This was accomplished by conducting a constant-rate pump test. Test data were interpreted by three methods: (1) drawdown vs. time (both logarithmic and semilogarithmic), (2) recovery …

A Seismic Reflection Survey Over The Wayne-25 Oil Field In Cass County, Michigan, Paul D. Horton

Masters Theses

The "optimum window" seismic reflection method was used in an endeavor to further define an oil producing structure in the Traverse Limestone. This method entails using a source-geophone offset which allows desired reflections to arrive in an undisturbed time zone.

Several sources in the study area produced seismic pulses with relatively high dominant frequency components ranging from 80 to 120 hertz. However, only small charges of dynamite produced sufficient energy to penetrate the glacial drift in the study area.

Preliminarily identified reflection arrivals from the targeted horizon were consistently masked in seismic profiling records by high amplitude, low velocity seismic …

The purpose of this research was to undertake a geochemical analysis in order to better understand the evolution of the kimberlite body and to elucidate on the garnet xenolith paragenesis.

Both instrumental neutron activation analysis (INAA) and scanning electron microscope analysis (SEM) were utilized in this research. The INAA revealed that with respect to other types of upper mantle rocks, the Lake Ellen kimberlite is enriched in both the light rare earth …

Deposition, Diagenesis, And Porosity Development Of The Middle Devonian, Lucas Formation In The West Branch Oil Field, Ogemaw County, Michigan, Scott Gregory Park

Masters Theses

The Lucas Formation in the West Branch Oil Field contains over 1000 feet of carbonates and evaporites deposited in restricted marine environments. Deposition ranged from a tidal flat environment (Richfield Member) to subaqueous basin central type deposition (Iutzi and Horner Members).

Early diagenesis of the Lucas Formation carbonates included dolomitization and related porosity development in certain depositional facies where physiochemical conditions were favorable. Significant porosity and permeability reduction occurred during burial resulting from anhydrite, celestite, and halite cementation. Calcite pseudopar and microspar (a neomorphic product) also reduced porosity.

Hydrocarbon production from the Lucas Formation in the West Branch Field is …

Nitrate Pollution Of Ground Water In Glacial Sediments Underlying A Fertigated Site In Kalamazoo County, Michigan, Michael Wireman

Masters Theses

In the central part of Schoolcraft Township high yield corn crops are successfully grown on soils developed on permeable outwash deposits. The high yields are made possible with the utilization of modern irrigation techniques and regular application of nitrogen fertilizer.

Excess nitrogen which moves past the root zone is easily converted to nitrate and leached to the shallow ground water. Water quality data from 103 ground-water samples in the vicinity of a 160-acre corn field in Section 11 clearly indicate that nitrate concentrations in the ground water beneath the field and beneath the area immediately downgradient from the field are …

Possible Role Of Petroliferous Materials In Sulfide Precipitation At The Frank R. Millikan Mine, Southeast Missouri, Clark Alan Niewendorp

Masters Theses

The Millikan Mine's ore body contains ubiquitous amounts of petroliferous materials occurring as blebs, coal-like pods and veinlets, and seeps coating mine stope walls. Emplacement of hydrocarbons into the ore occurred before the final episode of mineralization ceased, based on growth of dendritic galena in some coal-like bitumen and other paragenetic relationships. Growth of dendritic galena in a hydrocarbon substance suggests that hydrocarbons provided sulfur for galena mineralization by either abiogenetic reduction of sulfate or thermochemical evolution of organic sulfur. Texturally, it also suggests that the presence of hydrocarbons may have been responsible for some zones of rapid precipitate mineralization. …

The Effect Of Well Efficiency On In-Situ Permeability Test Results, Scott T. Dennis

Masters Theses

The purpose of this study was to determine what effect well efficiency has upon the results of in-situ permeability tests.

Several in-situ permeability tests were performed on wells during various stages of their development. The well efficiency was determined each time an in-situ test was performed. An accurate value of permeability was determined by performing local aquifer pumping tests. The accuracy of the results of the in-situ tests with respect to the aquifer pump test results were then compared to the efficiency of the well at the time of the test.

Test results showed that a linear relationship exists between …

Structural Geology And Geothermal Investigation Of The White Sulphur Springs Area, Montana, William G. Gierke

Masters Theses

Sevier thrusting in the White Sulphur Springs area was associated with left-lateral movement along the Lewis and Clark line . During Middle Miocene time, the Lewis and Clark line exhibited right-lateral movement, forming extensional features that either truncated Sevier structures or followed preexisting Sevier zones of weakness.

The Smith River Valley is a pull-apart basin that is filled with Tertiary volcanic ash and clay-rich sediments that are thermally nonconductive relative to surrounding rocks.

Hydrothermal activity in the area is associated with a structurally controlled circulation system accompanied by a high thermal gradient. Thermal discharge is constrained along the north-trending White …

Hydrodynamic Character Of The Dundee Limestone In The Central Michigan Basin, Ann Carol Little

Masters Theses

The Middle Devonian Dundee Limestone underlies most of the Lower Peninsula of Michigan. A potentiometric surface constructed of the formation, utilizing pressure data was compared to local and regional structure, permeability trends, specific gravity of the brines, oil accumulations, and surficial topography.

The data were distributed mainly in the central basin area, with information becoming more sparse around the basin margins. This created difficulties in the determination of the extent of control imparted by each of the factors, in flow direction. Surficial topography, on a regional scale, is likely the most influential of the controls, with the Dundee Limestone brines …

A Structural Investigation Of A Basement-Involved Thrust System In Southern Sphinx Mountain Quadrangle (Madison Range) Southwestern Montana, Jeffrey Scott Brown

Masters Theses

The Madison Range is the eastern limb of the Laramide Rocky Mountain foreland Madison-Gravelly Arch. The main segment of the Madison thrust system in the map area is the basement-involved Scarface thrust which dips westward, trends north-northwest, and places Archean rocks onto an overturned footwall of Cambrian through Cretaceous rocks. Foliation of Archean rocks in the footwall is folded with overlying sedimentary rocks.

The Shedhorn Mountain thrust splays from the Scarface thrust. It is exposed north and south of the Shedhorn Mountain anticline, but is blind beneath it. The Taylor fault, an east-dipping back thrust, is inferred to be associated …

Stratigraphic And Sedimentologic Analysis Of The Middle Devonian Filer Sandstone, John Charles Rodwan

Masters Theses

The Filer Sandstone, a multistory assemblage o£ lenticular sand bodies, is a member of the Middle Devonian Amherstburg Formation of the Detroit River Group in the subsurface of the western and central portion of the Michigan Basin. It is distinguished from the reworked eolian and nearshore marine sand facies of the underlying Sylvania Sandstone by recognition of its barrier island facies relationships and stratigraphic position within enclosing carbonates unique to the Amherstburg Formation. Lithologically, the Filer ranges from a fine-grained, carbonate-cemented, supermature quartzarenite at its upper shoreface facies, to a texturally-inverted sandy carbonate at its lagoonal facies. Facies distribution was …

Petrography, Diagenetic History, And Development Of Porosity In The Richfield Member Of The Lower Middle Devonian Lucas Formation, Northeast Isabella County, Central Michigan Basin, Kevin James Sullivan

Masters Theses

The Richfield Member of the lower Middle Devonian Lucas Formation is represented in the subsurface of northeast Isabella County, Michigan as a 180-foot-thick sequence of Interbedded limestone, dolomite and anhydrite. Richfield lithofacies within the study area reflect deposition in a complex patchwork mosaic of evaporative supratidal, in tertid al, shoal, and subtidal environments.

The present variations in Richfield porosities were caused almost entirely by post-depositlonal diagenetic changes. The carbonate units have undergone pervasive dolomltlzation of mud matrix, leaching of allochems, and extensive anhydrite void -fillin g . The best porosity developments are associated with partial to complete dolomitizatlon of the …

An Evaluation Of The Effectiveness Of Bentonite As A Soil Additive For The Cover Material On The Kl Avenue Sanitary Landfill, Kalamazoo, Michigan, Neal J. Carey

Masters Theses

A principle objective of using bentonite as a soil additive is to reduce the permeability of a cover material, thus, inhibiting the infiltration of surface waters at landfill sites.

Twenty-two cores of the KL landfill were taken to obtain in-situ soil columns for testing. Coefficients of permeability were calculated for each soil column using the falling-head permeameter. Mechanical and hydrometer analyses were used for the grain size analysis. The methylene-blue test was employed to determine the actual percentages of bentonite present in each soil column. X-ray diffraction work was done on the clay fraction of each soil column to verify …

Facies Development And Porosity Relationships In The Dundee Limestone Of Gladwin County, Michigan, Eric Lee Montgomery

Deposited during the Middle Devonian, the Dundee Limestone represents deposition in subtidal, intertidal, and restricted environments. The Buckeye Oil Field, located in south-central Gladwin County, is a combined stratigraphic and structural carbonate trap which produces from a series of intertonguing patch reefs, fringing sand bodies, and "intertidal island" fenestral zones. The major reef building organisms include stromatoporoids, corals, calcareous algae, brachiopods, and crinoids, with the stromatoporoids providing the major framework. The patch reef facies is composed of massive stromatoporoid …

The Provenance Of The Jacobsville Formation Of The Upper Peninsula Of Michigan Through A Petrographic Study, David Walter Lindsay

Masters Theses

The Upper Keweenawan Jacobsville Formation source areas were mixed source terranes with dominant terrane types changing regionally in relative abundances of sediment contribution. Dominant source terranes were older sediments, including a weathered soil zone, Upper Keweenawan Freda Sandstone and other recycled sandstones; plutonic Precambrian basement rocks;. Middle Keweenawan Portage Lake Volcanics; and the chlorite to staurolite grade metamorphic rocks and iron ranges of Michigan’s upper peninsula.

Depositional environments of the formation's four facies types range from fluvial to deltaic/lacustrine. Sediments were in transport for a short distance, resulting in grain freshness and angularity, moderate sorting and preservation of unstable sediments. …

Lithofacies And Geochemistry Of Interreef Carbonates, Middle Silurian, Michigan Basin, Eric N. Porcher

Masters Theses

The Niagara Group of the Michigan Basin is composed of reef, interreef, and basinal carbonates. The Niagara Group interreef has herein been divided into several litho facies: algal-laminated dolomicrite, bioturbated dolomicrite, intraclastic dolomicrite, wispy-laminated dolomicrite, crinoidal micrite, and nodular micrite. These interreef carbonates show a shallowing upward sequence.

The geochemistry of the Niagara Group interreef was examined in an attempt to delineate any geochemical gradients with respect to reefs. The geochemistry of the inter reef was determined by Particle Induced X-Ray Emission (PIXE) analysis. No significant geochemical gradients were found to be associated with reefs. Reasons for this may include: …

The Use Of Electrical Resistivity To Delineate A Brine Contamination Plume In The Walker Oilfield, Kent County, Michigan, Kent E. Meisel

Masters Theses

Contamination of groundwater with oil field brines was reported in the Walker Oil Field, Michigan. An electrical resistivity survey utilizing the Vertical Electrical Sounding method was conducted to test the method as an exploratory tool for delineating brine contamination in glacial deposits. The method was successful in defining the subsurface geology and delineating a shallow, confined aquifer, but the presence of extensive, conductive clays effectively masked the presence of brine contamination. The method was shown to be an effective exploratory tool for shallow investigations.

The Response Of The Kentucky River Drainage Basin To A Lowering Of Base Level Control, David B. Warwick

Masters Theses

The Kentucky River has responded to a lowering of base level control by: 1) deepening the course of its channel; 2) cutting off meanders as incision proceeded; 3) developing knickpoints on tributaries; 4) widening its valley; and 5) dissecting the upland surface.

Field work involved surveying streams to obtain profiles. Twenty streams covering 125 miles of river from Carrollton to Camp Nelson, Kentucky were surveyed. Knickpoints were defined from these profiles. Data from stream profiles showed knickpoint distances decreasing with increasing distance up river. Map work involved obtaining data for hypsometric curves. Hypsometric integrals were determined from these curves. Data …
