“…29.2). The deposits were first recognized in the COCORP (Consortium for Continental Reflection Profiling) OH-1 seismic reflection profile and other stratigraphic drilling tests from the subsurface of western Ohio (Shrake et al, 1991;Drahovzal et al, 1992;Fig. 29.4).…”

One of Earth's greatest mountain-building episodes, the Grenvillian orogeny, occurred with the assembly of the supercontinent Rodinia at the end of the Mesoproterozoic era, about 1.2-1.0 billion years ago. Weathering and erosion of the Grenvillian mountain chain, the roots of which can be traced today for nearly 12,000 km, produced huge volumes of sedimentary detritus that were dispersed by an enormous system of braided rivers. Erosion, denudation, and sediment throughput were enhanced by a lack of vegetation and vigorous continental weathering under a climate that favored strong chemical alteration.

“…Second, reflection profiling has shown that the high-grade gneisses of the Grenville province are commonly excellent reflectors and can be used to trace out the limits of the Grenville orogen. Third, reflec tion data from across the eastern and central midcontinent indi cate the presence of horizontal to mildly deformed reflectors above the Precambrian crystalline basement and beneath the Phanerozoic sedimentary strata (Sexton et al, 1986;Pratt et al, 1989;Shrake et al, 1991;Heigold and Kolata, 1993;Forsyth et al, 1994). Fourth, seismic reflection profiling has corroborated the conclusion reached by Keller et al (1983) that ancient rifts, which had a long-lasting effect on the tectonic development of the midcontinent, are widespread in the basement.…”

The crust of the northern U. S. Craton: A search for beginnings

Basement and Basins of Eastern North America

Except for limited areas, the basement of the northern U.S. midcontinent is cov ered by mildly deformed Phanerozoic sedimentary strata. Thus, geophysical studies, together with petrologic and isotopic age information obtained from deep drill hole samples, are the primary source of our knowledge of the nature of the crystalline basement crust. These rocks record the complex evolution of a large segment of the North American continental nucleus over Precambrian time and provide significant clues to subsequent deformation and sedimentation of the overlying Phanerozoic strata, as well as to modern tectonism. Significant progress has been made in charac terizing the crust of the craton over the past half century as a result of regional-scale gravity and magnetic anomaly data acquisition, seismic profiling that has imaged the crust and in some cases the upper mantle, and geochemical data that have identified the source and age of the basement. Despite this progress, the available geophysical data are generally inadequate even for regional studies and many critical geologic questions remain unanswered. However, the technology is available to dramatically improve data bases and our knowledge base of the nature, evolution, processes, and architecture of this region. The combined efforts of the geoscience disciplines are required to take advantage of this technology and apply it in an integrated manner to the search for the beginnings of the U.S. craton.

“…To the south of the transect along the Findlay arch, subsurface drilling and seismic reflection data (Pratt et al, 1988;Shrake et al, 1991) show the existence of a narrow rift of ~48 km width and with perhaps 4 km relief. The Upper Precambrian sedimentary sequence is only preserved in the block downfaulted into the Grenvillian basement.…”

“…The Upper Precambrian sedimentary sequence is only preserved in the block downfaulted into the Grenvillian basement. The sequence is dominated by well-cemented, red litharenites and may have been terrestrially deposited in arid or semi-arid conditions (Shrake et al, 1991). The tectonic affinity of the rift is presently unknown but may be related to the Precambrian-Cambrian midcontinent rift system that formed internally in the North America craton as the continental margin rifted to initiate the Iapetus Ocean (Thomas, 1991).…”

“…This sequence represents the base of the first Paleozoic marine transgression across the foreland from the southeast and the beginning of the construction of the Appalachian sedimentary wedge that thins to the northwest into Ohio (Sloss et al, 1949;Colton, 1970;Sloss, 1988). At its northwestern end, the Early Cambrian component of the wedge is represented by only ~80 m of quartzose sandstones grading down into basal quartzose conglomerates (Milici and de Witt, 1988;Shrake et al, 1991).…”

Global Geoscience Transect 20. Central Appalachians: Cratonic North America to the Atlantic Abyssal Plain

The Central Appalachian Geoscience Transect (GGT20) extends from the Atlantic coast across the Appalachian orogen to the Grenvillian structural front in the cratonic interior of North America. The character of the continental crust along the transect results from two Wilson cycles during Proterozoic and Phanerozoic time, comprised of the Grenvillian orogeny, Eocambrian rifting, Paleozoic orogeny, and Mesozoic rifting. The purpose of the transect is to address questions regarding the Paleozoic development of the eastern margin of North America related to: (1) structural development of the middle and lower crust during rifting and orogeny; (2) sources of major potential field anomalies, including the New York-Alabama magnetic lineament; (3) displacement termination of the Appalachian foreland thrust; and (4) thrust displacement transfer from the crystalline terranes into the foreland.
