Book Description
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 conditions and porosities in the basin. Thermal maturation data (1149 samples, in 32 formations/groups, from 128 wells) show irregular distribution directly above and adjacent to the Midcontinent Rift. Results of short (

Book Description
Given present day heat flow and burial depths in the Michigan Basin, hydrocarbons should be immature. However, oil and gas are abundant within the basin. Our hypothesis is that thermal maturation distributions in the Michigan Basin can be explained by variations in proximity to the Midcontinent Rift (MCR) system, thermal cooling, crustal convection, high temperature fluid advection, and eroded overburden. For each of the seven wells in this study, a geohistory plot is coupled with a range of geodynamic models to calculate the thermal and maturation histories of each sediment unit within the well. Backstripping was used to generate basement heat flow estimates. Time temperature index values are calculated based on the thermal models. Comparison of calculated time temperature index values and recorded thermal maturation data from surrounding wells are used to test the hypothesis. Calculations show that well locations above the MCR (Grand Traverse, Missaukee, Gratiot, and Livingston) require 1000 m of eroded overburden, thermal cooling, crustal convection, and high temperature fluid advection to match surrounding thermal maturation data in the Michigan Basin. Well locations away from the MCR (Ogemaw and Lenawee) require 1000 m of eroded overburden, thermal cooling, and high temperature fluid advection to match surrounding thermal maturation data in the Michigan Basin.

Book Description
Indications of anomalous paleo-temperatures exist in strata of the Michigan basin, USA. The thermal history of the basin was investigated through identification and analysis of authigenic components in two Upper Paleozoic strata, the Devonian Dundee Formation and Mississippian Marshall Sandstone. Formation conditions for diagenetic phases in both units were estimated through a variety of means and compared to conditions expected for a simple burial model. Authigenic clays identified in the Marshall via X-ray diffraction are expected to have formed at temperatures above what would have been produced by burial alone. Stable isotope and fluid inclusion analysis indicate the same for secondary carbonates in the Dundee. K-Ar age dating of Marshall authigenic illite provide ages of approximately 280 Ma. This age may reflect an illite formation period in the Permian or may be an integrated age representing multiple periods of illitization. Dolomite in the Dundee and illite in the Marshall are likely to have formed under hydrothermal conditions. The results of this study are part of a larger body of evidence that suggests episodic and extensive hydrothermal events have influenced the thermal history of the Michigan basin. These events are due to the reactivation of faults in the Proterozoic rift that underlies the basin and maybe related to thermal convection within the igneous rift body or Appalachian tectonic events.
