    Geoloaic District. Subsequent Stratigraphic Studies in This Area

    DEVONIAN STRATA AND PALEOENVIRONMENTS: CHAUTAUQUA COUNTY REGION: NEW YORK STATE GORDON C. BAIRD and GARY G. LASH Department of Geosciences State University of New York College at Fredonia Fredonia, New York 14063 INTRODUCTION The history of the study of the Paleozoic stratigraphic divisions in New York State spans, at least, two centuries, and it records the early development of important concepts centrally germane to the study of sedimentary basins worldwide (see Tesmer, 1989). The works of James Hall, John Clarke, HenryS. Williams, Joseph Barrell, and George Chadwick are well known to most sedimentary workers, as are those of numerous subsequent workers. In particular, the sedimentary sequences of the Allegheny Plateau Region (••southern Tier" region) served as important sources of information for refinement of the fac ies concept ar.d for the widespread recognition of the westwardly prograding Catskill Delta Complex which is the primary Paleozoic story recorded in Southern Tier bedrock deposits (see Chadwick, 1924, 1933; Cooper, et al., 1942; Caster, 1934; Woodrow, 1985). ---- The first significant geologic work relating to the Chautauqua County region was presented in James Hall's (1843) Survey of the Fourth Geoloaic District. Subsequent stratigraphic studies in this area inclu e Clarke (1903), Chadwick (1923, 1924), Caster (1934), Pepper and de Witt (1950, 1951) and de Witt and Colton (1953). In northwest Pennsylvania, significant synthetic contributions include I.C. White (1881), Butts (1906-1908), Chadwick (1925), Caster ·(1934), Pepper et al. (1954). In Ohio, deposits equivalent to parts of the New York and -­ Pennsylvania Upper Devonian section (Chagrin Shale) have been the subject of recent paleoenvironmental studies (see Weidner and Feldmann, 1983; Schwimmer and Feldmann, 1990).

CRAFT Engineering Geologist (retired), New York State Department of Environmental Conservation (Geology of New York, 1843) 118 INTRODUCTION On a hilltop in Rock City State Forest, three miles north of Salamanca, New York, the Salamanca Conglomerate outcrops in spectacular fashion. Part of the Upper Devonian (late Fammenian) Cattaraugus formation, the quartz-pebble conglomerate forms a five to ten-meter high escarpment and topographic bench at ~ 2200 feet elevation amid a mature cherry-maple-oak forest. In places, house- sized blocks have separated from the escarpment along orthogonal joint sets and variably “crept” downhill. Where concentrated, a maze of blocks and passageways may form so-called “rock cities”, an impressive example of which is Little Rock City. The well-cemented blocks permit extraordinary 3-D views of diverse and ubiquitous sedimentary structures and features. Six outcrop areas with the most significant exposures were logged over a four-kilometer north-south traverse. The traverse largely follows the east-facing hillside which roughly parallels the presumed paleoshore of the Devonian Catskill Sea. Extensive “bookend” outcrops at the north face (off the Rim Trail) and at the southeast perimeter (“Little Rock City” along the North Country-Finger Lakes Trail) and vertical (caprock) control allow a nearly continuous look at spatial and temporal changes in sedimentary deposits along a four-kilometer stretch of inferred late Devonian seacoast. We’ll examine several outcrops which reflect a high-energy and varied coastline as summarized below.

(paper cover) FOEEWOBD The "Lexicon of geologic names of the United States" by M. Grace Wilmarth, published in 1938 and reprinted in 1951 and 1957, met a long standing need and continuing demand for a compilation of geologic names. Plans made for future compilations as new names and revisions appeared were interrupted during the years of World War II. In 1952 a sustained effort was begun toward review of geo­ logic publications necessary to furnish a background for preparation of a new edition. After the review was brought up to date in 1956, the present compilation was prepared in order to furnish to the geo­ logic profession, as quickly as possible, some of the essential data concerning the new names that have appeared since 1935.

Fundao, 21949-900 Rio de Janeiro, RJ, Brazil Received 9 February 2000; accepted 27 July 2000 Abstract Palynomorph distribution in Euramerica and western Gondwana, from the Latest Givetian to the Latest Famennian, may be explained, to some extent, by climatic changes. Detailed miospore stratigraphy dates accurately the successive steps of these changes. Interpretation is built on three postulates which are discussed: Euramerica at slightly lower latitudes than generally accepted by most paleomagnetic reconstructions; a conodont time-scale accepted as the most used available subdivision of time; and Late Devonian sea-level fluctuations mainly governed by glacio-eustasy. The Frasnian±Famennian timescale is also evaluated. The comparison, based on conodont correlations, between Givetian and most of the Frasnian miospore assemblages from, respectively, northern and southern Euramerica demonstrates a high taxonomic diversity in the equatorial belt and much difference between supposed equatorial andŽ. sub tropical vegetations. On the contrary, a similar vegetation pattern and therefore probably compatible climatic conditions were present from tropical to subpolar areas.

    Depositional and Tectonic Models for Upper Devonian Sandstones in Western New York State

    Depositional and Tectonic Models for Upper Devonian Sandstones in Western New York State Saturday Field Trip A2 Sandstone Outcrops from Allegany, Cattaraugus and Wyoming counties. Guidebook for the field trip held October ih, 2006 in conjunction with the 35th Eastern Section AAPG Meeting and 78th NYSGA Field trips held in Buffalo, New York Gerald J. Smith and Robert D. Jacobi, Field trip leaders and guidebook authors UB Rock Fracture Group Department of Geology University at Buffalo Buffalo, New York Field trip sponsored in part by NYSERDA (New York State Energy Research and Development Authority) October ih, 2006 We thank STATEMAP, EDMAP, NYSERDA, and Industrial Associates for funding the research reported herein. Saturday A2 Depositional and Tectonic Models for Devonian Sandstones 54 INTRODUCTION Goals and Objectives The intention of this field trip is to visit examples of the major clastic depositional environments prevalent in the Late Devonian Appalachian foreland basin. Additionally, we will examine how syndepositional faulting influenced, and in some cases controlled, the deposition of the major petroleum reservoirs. This field trip represents a continuing evolution in our understanding of the Upper Devonian depositional controls. Our earliest sandstone field trip (Jacobi et al., 1990) proposed turbiditic and storm depositional environments in a basin setting, consistent with the views of the time that the Appalachian Basin in New York State was essentially structurally featureless (except for rare folds in the south and the Clarendon-Linden Fault), and that the shorelines had been muddy. Our next field trip (Jacobi and Smith, 1999) showed that post-depositional faulting was likely, that sandy/silty shoreface environments were possible farther east, and that syndepositional faulting affected the Rushford Formation.
  • The Classic Devonian of the Catskill Front: a Foreland Basin Record of Acadian Orogenesis

    The Classic Devonian of the Catskill Front: a Foreland Basin Record of Acadian Orogenesis

    NYSGA 2009 Trip 7 – Ver Straeten Trip 7 – Ver Straeten The Classic Devonian of the Catskill Front: A Foreland Basin Record of Acadian Orogenesis Charles A. Ver Straeten New York State Museum, the State Education Department, Albany, NY 12230, [email protected] INTRODUCTION Foreland basins sedimentary rocks preserve a record of the evolution of a mountain belt. Indeed, adjacent to ancient, deeply eroded orogens like the Devonian Acadian mountain belt, the foreland basin sedimentary succession is a key source of data on the timing and character of orogenic events and processes long since eroded away. Making viable interpretations of orogenesis from foreland basin sedimentary rocks is, of course, not simple and straightforward. For example, look at the evolving understanding of Devonian volcanic ash beds (“tephras”, “tuffs”, “K-bentonites”) and their implications for explosive Acadian volcanism, one of the author’s primary research in- terests (Ver Straeten, 2004a, 2008; Ver Straeten et al., 2005). Prior to the mid-1970s, only a few thin volcanic tephras were known from Devonian strata across eastern North America. Now approximately 100 beds are known from the Devonian of the Appalachian basin. Older perspectives interpreted each bed to represent a single explosive volcanic eruption. Microstratigraphic and geochemical study of the beds, however, indicate that many are multi-event layers, with a history of amalgamation of multiple eruptions, resedimentation on the sea floor, and/or mixing with detrital sediments. Furthermore, it is unknown how many te- phra layers, erupted over ca. 60 million years, were not preserved in the sedimentary rock record. The question then arises, does the existing record of foreland basin tephras yield a viable proxy of Acadian volcanism through time, despite biased and incomplete preservation of individual eruptions? This field trip and paper examine the Devonian (+/- Upper Silurian) sedimentary rock succession in the Catskill Front of eastern New York, with additional perspectives from across New York and the Appalachian basin.
