“…In fact, such perturbations may allow us to identity important faults within the cratonic interior. One example is the orientation of the field in northern Ohio around the area of the Bowling Green Fault (Onasch and Kahle, 1991), where the shortening direction is perpendicular to the regional pattern.…”

Mechanical twins in calcite from carbonates of the Paleozoic cover sequence of eastern North America preserve a record of far-field paleostress and strain transmis sion that is associated with late Paleozoic ("Alleghenian") activity at the Laurentian plate margin. Calcite twinning analysis permits the determination of regional differ ential paleostress (gd) and finite strain (e) patterns that are combined to obtain rheologic properties of the cover rocks. The combination of strain vs. distance and stress vs. distance relationships produces a stress-strain relationship of the form: e = 1(H . aD2. Modeling of linear viscous rheologies by others supports the observation of far-field effects transmitted from this convergent margin if the convergence vector between the Laurentian and Gondwanan plates is at a high angle to the margin. Using differential paleostress data from calcite twinning at the orogenic front, high fluid pressure is calculated (k = 0.65). Moreover, the occurrence of twinning in the carbon ate cover changes its permeability, perhaps permitting fluids to migrate along evolving grain boundaries in rocks that otherwise have low porosities.

“…Experimental studies in siliciclastic (Amini and Sama, 1999;Moretti et al, 1999) and carbonate (Weaver and Jeffcoat, 1978) sediments also produced similar structures. Finally, perhaps the most convincing evidence in support of seismic origin is the proximity of the rocks with softsediment deformation to faults known to have been active during Silurian time (Onasch and Kahle, 1991;Onasch, 1995).…”

Faults in Paleozoic rocks overlying the boundary are thought to result from reactivation of basement structures associated with the front (Wickstrom and Gray, 1988;Onasch and Kahle, 1991;Stark, 1997). One such fault in northwest Ohio and southeast Michigan is the Bowling Green fault (Fig.…”

Middle and Upper Silurian carbonates in western Ohio and southeastern Michigan contain an extensive array of soft sediment deformation structures: concordant and discordant breccias, folds and faults, homogenized zones, sediment intrusions, and fault-graded beds formed by hydroplastic deformation, liquefaction, and fluidization. The variety of behaviors indicated by the range of deformational styles is a consequence of the varying degrees of cementation at the time of deformation. The unlithified nature of the sediments at the time of deformation, the type and large areal distribution of structures, and similarity to structures related to modern earthquakes indicate that the deformation is seismically induced. The source of the seismicity is believed to be nearby faults associated with the Grenville front which are known to have been active during deposition of Silurian strata.on April 4, 2015 specialpapers.gsapubs.org Downloaded from

“…In addition, during a particular pulse, not all belts are reactivated. Marshak and Paulsen, along with others Onasch and Kahle, 1991;Heigold and Kolata, 1993;and Holbrook, 1993) consider the geometry of the stress field and the orientation of zones of weakness or heterogeneity in the Earth's crust to be important in controlling movements on the craton. Displacements that reverse earlier offsets occur in the Illinois, Williston, Baltic, and Paraná basins and on the Russian platform (Bertagne and Leising, 1991;Kolata and Nelson, 1991;GerFigure 14.…”

Plate tectonic interactions apparently have had a profound influence on the evo lution of basins in the supposedly stable interiors of cratons. Evidence for significant tectonic control of these deceptively simple basins and their stratigraphic successions has been steadily growing, but their evolution remains poorly understood and the mechanisms controlling their development remain conjectural.Data collected from a number of interior cratonic basins suggest that basin form ing, filling, and modifying processes take place under stress fields of far-reaching extent that appear to be directly related to plate tectonics. Some stress fields appear to be propagated from collision fronts, as suggested by contractional foreland defor mation features in interior cratonic basin settings. Such features have been observed in Europe, Asia, and the midcontinent of North America, in some cases more than 1,300 km beyond any readily recognized deformation front. Other supporting evi dence has been found in the regional strain fabric of calcite in Paleozoic rocks of the midcontinent. It thus appears likely that plate collisions have transmitted intraplate stresses well into the interior of continental plates.Unconformity-bounded sequences also provide clues about the impact of regional tectonics and directed stress fields. In North American interior cratonic basins, as well as those of other continents, sequence-bounding unconformities that represent impor tant lacunae are accompanied by structural deformation, including tilting, that indi cates the directionality of stress fields. The geometries of sequences change above and below unconformity surfaces. In many instances, the direction or dip of a sequence and its three-dimensional orientation differs from that of an underlying or overlying sequence on a basin-wide scale.Within a basin, nonlinear, intermittent subsidence curves appear to be the rule. The long history of interior cratonic basins is characterized by recurrent subsidence and uplift. Basins and their sequences appear to respond to pulsating forces that change direction episodically. The stress fields appear to have effective "reaches" that control basin evolution for periods of time and then disappear.Overall, cratonic basins and the continental plates on which they are situated appear to respond to changing stress fields related to divergence, convergence, and collision of plates. The manner in which they respond appears to be a function of inhomogeneities in the crust. Epeirogeny has also played a role, for reasons that are not entirely clear, but possibly the epeirogenic responses are related to the nature of the Earth as a heat engine that induces physical-chemical changes in the Earth's crust and mantle.
