Abstract

Hydrocarbon bearing structures in the Paleozoic section of the Michigan basin possess different structural styles and orientations. Quantification of the direction and magnitude of shortening strains by applying a calcite twin-strain analysis constrains the mechanisms by which these structures may have developed. The calcite twin-strain analysis and fracture orientations in Paleozoic rocks indicate that the mean direction of compression controlling structural development ranged from SE-NW to nearly E-W. This direction of compression nearly parallels the majority of structures in the basin, and provides insight into their origin.

The structural geometries of fields considered in this study can be explained by models for deformation in the Paleozoic cover above basement faults with varying components of strike-slip and dip-slip motion. Variation in structural style appears to be related to reactivation of basement lines of weakness with different orientations in response to the same regional compression.
