An understanding of regional orogenic, climatic, and eustatic processes is critical to the interbasinal correlation of Paleozoic strata in eastern North America. Tectonic activity associated with the culmination of Appalachian Orogenic events has been shown to have regional influence on paleostructure and sediment dispersal in the Appalachian foreland basin and adjacent intracratonic Illinois and Michigan basins. The culmination of the Acadian Orogeny at the end of the Devonian represents the beginning of a period of general tectonic quiescence extending throughout the early and middle Mississippian in eastern North America. Early Mississippian strata in the Michigan basin is distinctive and marks …

Thermal History Of The Michigan Basin: Results From Thermal Maturation Data And Geodynamic Modelling, Kirk A. Wagenvelt
Masters Theses
Thermal cooling, crustal convection, high temperature fluid advection, and 1.0 Km of eroded overburden are required to explain thermal maturation observations in the Michigan Basin. Observed tectonic subsidence in central Michigan follows an exponential decay indicative of thermal cooling following an anomalous heating event. Crustal convection is responsible for episodes of rapid subsidence coincident with the late Paleozoic Appalachian orogeny. Fluid advection through dilated faults reactivated by the Alleghanian orogeny brought hot fluids (as much as 255⁰ C) to the surface and impacted thermal maturation of organic matter in sediments. Models require 1.0 Km of eroded overburden to model thermal …
Naturally-Occurring Metals Concentrations In Michigan Soils: A 2015 Survey, Zachary Lowell Spotts
Naturally-Occurring Metals Concentrations In Michigan Soils: A 2015 Survey, Zachary Lowell Spotts
Masters Theses
Closure of hazardous waste sites can be aided through the use of a soil background survey for metals. Data for these studies come from either field sampling or publicly available environmental files. Previous studies were conducted in Michigan, known as the Michigan Background Soil Survey (MBSS). The current update is a refinement and improvement of the 2005 update. New data was collected from publicly available environmental files and other sources. Both the current update and the 2005 update differentiated data by soil type and glacial lobe. GIS analysis was used to observe spatial distribution of the data and to determine …
