Geology and Monazite Content of the Goodrich Quartzite, Palmer Area, Marquette County, Michigan

Description: From abstract: The Palmer area, which is on the south limb of the Marquette synclinorium, consists of a down-faulted block of pre-Cambrian sedimentary rocks about 4 miles long and three-quarters of a mile wide. The block is composed mainly of middle Huronian Ajibik quartzite and Negaunee iron-formation and upper Huronian Goodrich quartzite,. Monazite occurs in the Goodrich quartzite as rounded detrital grains concentrated mainly in the matrix of quartz pebble conglomerate which is interbedded with coarse-grained quartzite.

Greens Creek Uranium Occurrence, Marquette County, Michigan

Description: From abstract: Metatorbernite and bassetite are present in altered carbonaceous and quartzose slate of probable upper Huronian age. The slate is part of a small inlier of Huronian rocks between the Gwinn iron district to the southeast and the Marquette iron district to the northwest, Marquette County, Mich. Samples taken from a shallow trench, which was dug in the area of highest radioactivity, contained as much as 0.68 percent uranium. A 4-foot channel sample of the slate contained 0.036 percent uranium.

Hydrogeochemical and Stream Sediment Reconnaissance Basic Data for Iron Mountain NTMS Quadrangle, Michigan; Wisconsin

Description: From abstract: Results of a reconnaissance geochemical survey of the Iron Mountain Quadrangle, Michigan; Wisconsin are reported. Field and laboratory data are presented for 479 groundwater samples, 369 stream sediment samples, and 389 stream water samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

A Spatial-Temporal Analysis of Retail Location and Clustering: A Case Study of Port Huron, MI

Description: Retail geography is a field of study that is growing in significance and importance within the academic, business, economic, and governmental realms. This study's main focus is on the changing retail environment with regards to business location and function within a small Midwestern city. The research focuses on Port Huron, Michigan because of the growth and shift of the retail community within the city over the past twenty years. The study specifically examines the changing influence and roles of Port Huron's central business district and of Birchwood Mall a retail development opened on the urban area's north end in 1990. The study uses the chi-squared, ANOVA, and cross tabulation statistical tests to analyze the changing geography of retail functions in the city. These statistics are used along with relative entropy equations to distinguish areas of high diversification, changing area functions, and common locations for multiple retail types.

Suspended sediment transport in the benthic nepheloid layer in southeastern Lake Michigan

Description: Time series observations of water temperature, water transparency, and current velocity were made at four stations located on the lake slope of southeastern Lake Michigan. The observations show that during stratified conditions the benthic nepheloid layer is probably not maintained by the local resuspension of bottom sediment. A more likely source is sediment resuspended further inshore and then transported across the shelf and slope during downwelling events. Internal wave action may be an important source of energy for this transport. Although sediment trap studies suggest that resuspension does occur, it is more likely that increased fluxes observed near the bottom are due to the vertical redistribution of material already in suspension. A benthic nepheloid layer also exists at times during the unstratified period, when occassionally enough energy reaches the bottom to directly resuspend bottom material at the sites.

Advanced Characterization of Fractured Reservoirs in Carbonate Rocks: The Michigan Basin

Description: The main objective of this project is for a university-industry consortium to develop a comprehensive model for fracture carbonate reservoirs based on the ''data cube'' concept using the Michigan Basin as a prototype. This project combined traditional historical data with 2D and 3D seismic data as well as data from modern logging tools in a novel way to produce a new methodology for characterizing fractured reservoirs in carbonate rocks. Advanced visualization software was used to fuse the data and to image it on a variety of scales, ranging from basin-scale to well-scales.
