Fieldwork conducted in Pontotoc County,Mississippi, targeted two sites containing montmorillonitic sand in the Maastrichtian Ripley Formation. U-Pb detrital zircon (DZ) ages from these sands (n = 649) ranged from Mesoarchean (~2870 Ma) to Pennsylvanian (~305 Ma) and contained ~91% Appalachian-derived grains, including Appalachian–Ouachita, Gondwanan Terranes, and Grenville source terranes. Other minor source regions include the Mid-Continent Granite–Rhyolite Province, Yavapai–Mazatzal, Trans-Hudson/Penokean, and Superior. This indicates that sediment sourced from the Appalachian Foreland Basin (with very minor input from a northern or northwestern source) was being routed through the Mississippi Embayment (MSE) in the Maastrichtian. We recognize six lithofacies in the field areas interpreted as barrier island to shelf environments. Statistically significant differences between DZ populations and clay mineralogy from both sites indicate that two distinct fluvial systems emptied into a shared back-barrier setting, which experienced volcanic ash input.

In addition to low amplitude ( 100 m) long wave length ( 15 km) folds the Upper Devonian sediments of western New York contain many< mesoscopic-scale structures< including joints that can be systematically related to the Alleghanian Orogeny. Based on the nonorthogonality of cleavage and joints, the Alleghanian Orogeny in the Finger Lakes District of New York consists of at least two phases which Geiser and Engelder (1983) correlate with folding and cross-cutting cleavages in the Appalachian Valley and Ridge. To the southeast of the Finger Lakes District the earlier Lackawanna Phase is manifested by formation of the Lackawanna syncline and Green Pond outlier and the development of a northeast-striking disjunctive cleavage within the Appalachian Valley and Ridge mainly fromthe Kingston Arch of the Hudson Valley southwestward beyond Port Jervis, Pennsylvania (Fig. 1).

  • Chapter 1: Sequence Stratigraphy of the Glenshaw Formation
    Martino, R. L., 2004, Sequence stratigraphy of the Glenshaw Formation (middle–late Pennsylvanian) in the central Appalachian basin, in J. C. Pashin and R. A. Gastaldo, eds., Sequence stratigraphy, paleoclimate, and tectonics of coal-bearing strata: AAPG Studies 1 in Geology 51, p. 1–28. Sequence Stratigraphy of the Glenshaw Formation (Middle–Late Pennsylvanian) in the Central Appalachian Basin Ronald L. Martino Department of Geology, Marshall University, Huntington, West Virginia, U.S.A. ABSTRACT he Glenshaw Formation consists predominantly of sandstones and mud- rocks with thin limestones and coals, which are thought to have accumu- T lated in alluvial, deltaic, and shallow-marine environments. Analysis of 87 Glenshaw outcrops from southern Ohio, eastern Kentucky, and southern West Vir- ginia has revealed widespread, well-developed paleosols. These paleosols are used, along with marine units and erosional disconformities, to develop a high-resolution sequence-statigraphic framework. The tops of the paleosols constitute boundaries for nine allocycles, which are interpreted as fifth-order depositional sequences. Allocycles in this framework correlate with similar allocycles described from the northern Appalachian basin. A sequence-stratigraphic model is proposed that provides a framework for in- terpreting facies architecture in terms of base-level dynamics linked to relative sea level changes. Lowered base level caused valley incision along drainage lines and sediment bypassing of interfluves, which led to development of well-drained paleo- sols. Rising base level produced valley filling by fluvioestuarine systems (lowstand systems tract/transgressive systems tract), whereas pedogenesis continued on inter- fluves. As drainage systems aggraded, the coastal plain water table rose, and in- terfluvial paleosols were onlapped by paludal and lacustrine deposits.

BRISSON AND JALEIGH Q. PIER Geosciences & Ecology and Evolutionary Biology, University of Connecticut, Storrs, CT 06269 INTRODUCTION Earth-system perturbations caused a series of mass extinction events during the Devonian Period, including the Taghanic event in the Givetian, the Lower and Upper Kellwasser events in the Frasnian, and the Hangenberg event in the Famennian (House, 2002; Bambach, 2006). These extinctions occurred against the backdrop of orbitally forced sea-level fluctuations, the Acadian Orogeny (Averbuch et al., 2005), the expansion of plants and animals on land (Algeo et al., 1995), and ecological changes in the marine biosphere (Signor and Brett, 1984; Bambach, 1999). The Frasnian-Famennian boundary in particular represents a significant global crisis, considered one of the “big five” mass extinctions (Raup and Sepkoski, 1982) that led to the demise of the widespread and diverse Devonian
