COOPER Illinois State Geological Surve^^ Urbana^ Abstract—A microfauna of smaller Foraminifera from the cuttings of a water well in Cache, southern Alexander County, shows the occurrence of Lower Eocene (Paleocene) sediments almost to the northern limit of the Mississippi embayment. Six families are represented, comprising 15 genera and 30 species. More than half of the species belong to the Lagenidae, with two to four species in each of the Hetero- helicidae, Ellipsoidinidae, Rotaliidae, Globigerinidae, and Anomalinidae.

Riv. It. Paleontol. Strat., 126(2): 395-446. Keywords: K-Pg boundary event; Gadiformes; Heterenchelyidae; otolith; extinction; survival. Abstract. Otolith assemblages have rarely been studied across the K-Pg boundary. The late Maastrichtian Kemp Clay of northeastern Texas and the Fox Hills Formation of North Dakota, and the early Danian Clayton Formation of Arkansas therefore offer new insights into how teleost fishes managed across the K-Pg boundary as reconstructed from their otoliths. The Kemp Clay contains 25 species, with 6 new species and 2 in open nomenclature and the Fox Hills Formation contains 4 species including 1 new species. The two otolith associations constitute the Western Interior Seaway (WIS) community.

  • Lignite and the Midway-Wilcox Stratigraphic Boundary, Alabama and Mississippi By
    Lignite and the Midway-WIlcox Stratigraphic Boundary, Alabama and Mississippi By C. R. Meissner, Jr. and S. E. Heermann 1982 Open-file Report 82-673 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards and Stratigraphic nomenclature. Introduction The boundary between the Midway Group of Paleocene age and the overlying Wilcox Group of Paleocene - Lower Eocene age needs clarification in the border area along east-central Mississippi and west-central Alabama. A lignite bed described in the Oak Hill Member of the Naheola Formation, upper Midway Group, in Alabama (Daniels, 1973) appears to be the same bed as that described in the Fearn Springs Member of the Nanafalia Formation, lower Wilcox Group, just across the border in Mississippi (Foster, 1940). If the lignite bed actually is continuous from Alabama into Mississippi, then it is Impossible for it to cross a major stratigraphic boundary such as that between the Midway and Wilcox Groups, especially since this boundary has been described as a major unconformity (Hughes, 1958). The U.S. Geological Survey Lexicon of Geologic Names of the United States from 1936-1960 (Keroher and others, 1966) cites eight authors, none of whom completely agree on the definition of the Fearn Springs Member and its stratigraphic position. MacNeil (1946) gives the option of three different positions for the Midway-Wilcox boundary, one at the base of the Naheola Formation (upper Midway), one at the base of the Coal Bluff member of the Naheola, and one at the base of the Fearn Springs Member of the Nanafalia Formation (lower Wilcox) (fig.

    U-PB DETRITAL ZIRCON GEOCHRONOLOGY OF THE LATE PALEOCENE EARLY EOCENE WILCOX GROUP, EAST-CENTRAL TEXAS A Thesis by PRESTON JAMES WAHL Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Thomas E. Yancey Co-Chair of Committee, Mike Pope Committee Members, Brent V. Miller Walter Ayers Head of Department, Rick Giardino August 2015 Major Subject: Geology Copyright 2015 Preston James Wahl ABSTRACT Sediment delivery to Texas and the northwestern Gulf of Mexico during the Early Paleogene represents an initial cycle of tectonic-influenced deposition that corresponds with the timing of late Laramide uplift. Sediments shed from Laramide uplifts to east- central Texas and the northwestern Gulf of Mexico during this time are preserved in strata of the Wilcox Group and lower Claiborne Group. U-Pb dating of detrital zircons from closely spaced stratigraphic units within these groups and the underlying Midway Group by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) reveals the relative arrival time of late Laramide-age detrital zircons to east-central Texas and distinct detrital zircon age assemblages. Comparison of zircon age assemblages from this study with data from potential source regions and additional Wilcox and Claiborne Group samples along the Texas and Louisiana Gulf Coastal Plain provides insight into paleodrainage during the Early Paleogene. The relative arrival time of late Laramide-age detrital zircons to east-central Texas corresponds with deposition of the Hooper Formation of the Wilcox Group, although the presence of these detrital zircons fluctuates within younger samples.

Email address: [email protected] 1ntroduction The study area encompasses the entire Mejillones Peninsula in northern Chile (Fig . 1). The peninsula has been undergoing fault-controlled extension since early Miocene (Hartley and Jolley, 1995). East-west extension and latest Pliocene to Pleistocene regional uplift have been linked to subduction tectonic erosion and subcrustal accretion of material removed at the trench, respectively (De louis et al., 1998; von Huene et al., 1999; Hartley et al., 2000). Extension has resulted in the formation of two main halfgraben basins bounded by N-S trending, east­ dipping normal faults: the Caleta Herradura-Pampa dei Aeropueto (CHPA) basin to the west and the Pampa de Mejillones (PM) basin to the east. Detailed study of map-scale stratal geometries and stratigraphie bounding surfaces has enabled us to develop a Neogene stratigraphie framework of these sedimentary basins that can be used to reconstruct the history of subsidence and faulting.
