  • 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.

  • Late Devonian and Early Mississippian Distal Basin-Margin Sedimentation of Northern Ohio1
    Late Devonian and Early Mississippian Distal Basin-Margin Sedimentation of Northern Ohio1 THOMAS L. LEWIS, Department of Geological Sciences, Cleveland State University, Cleveland, OH 44115 ABSTRACT. Clastic sediments, derived from southeastern, eastern and northeastern sources, prograded west- ward into a shallow basin at the northwestern margin of the Appalachian Basin in Late Devonian and Early Mississippian time. The western and northwestern boundary of the basin was the submerged Cincinnati Arch. The marine clastic wedges provided a northwest paleoslope and a distal, gentle shelf-edge margin that controlled directional emplacement of coarse elastics. Rising sea levels coupled with differences in sedimen- tation rates and localized soft-sediment deformation within the basin help explain some features of the Bedford and Berea Formations. The presence of sand-filled mudcracks and flat-topped symmetrical ripple marks in the Berea Formation attest to very shallow water deposition and local subaerial exposure at the time of emplacement of part of the formation. Absence of thick, channel-form deposits eastward suggests loss of section during emergence. OHIO J. SCI. 88 (1): 23-39, 1988 INTRODUCTION The Bedford Formation (Newberry 1870) is the most The Ohio Shale, Bedford, and Berea Formations of lithologically varied formation of the group.

The sequence of sediments both to the east and west and reaches its maximum is characterized by (1) gray mudshale, clayshale, siltstone, thickness in the Cleveland area.
