Gordon Baird, Carlton Brett, and Alexander J. Bartholomew v Preface and Acknowledgements It is a great pleasure to welcome you to the 75th annual meeting of the NYSGA. Hartwick College and the State University of New York College at Oneonta are this year's host institutions and we hope that you take some time to visit both schools a tour our respective Geology Departments. This year's field trips cover a broad array of topics and regions and will take you from the depths of caves to the tops of Catskill and Adirondack peaks. The range of topics is certainly varied including the fields of metamorphic and igneous petrology, structural geology, sedimentolgy, hydrology and paleontology. In honor of the 75th anniversiary of NYSGA, we are fortunate to have Dr. Harrison Schmitt as our keynote speaker. Having walked on the moon, Dr. Schmitt brings a very unique perspective on geology and we look forward to hearing his address. It is fitting that a lunar geologist present at NYSGA, since both the moon and the State of New York have one thing in common; terrific exposures of anorthosite. NYSGA meetings are unique and refreshing in that they focus on learning about geology by going out into the field and seeing it first hand. Because of this focus, NYSGA depends on the many individuals who have dedicated themselves to planning and running field excursions. Their tireless efforts are what make NYSGA meetings so enjoyable and valuable. I thank all of the authors and trip/workshop leaders, for their hard work. I would also like to thank Dr. Jim Ebert for arranging the meeting (as well as being a trip leader and author of multiple field guides) and for his help in making this field guide a realitiy. Jim served as the field guide editor for the 1991 NYSGA meeting held in Oneonta, and his expertise, advice and calming influence helped me immensely. Thanks Jim. In addition, I thank the staff at SUCO and Hartwick College for all of their help and technical support, and finally, I thank my students who make what I do so enjoyable.

ABSTRACT Terrigenous clastic deposits equivalent to the upper most Moscow Formation and Tully Formation record a number of key sedimentological-paleontological events that occurred during the latest part of the Middle Devonian Givetian Stage. These deposits, last mapped in detail by G. Arthur Cooper and H.S. Williams in the 1930s, have been the subject of extensive stratigraphic mapping work by the present authors over the past five years. Goals of this mapping project are: 1) to identify divisions and boundaries correlative to units identified in the Tully Limestone further west through the classic work of Phillip Heckel in the sixties and seventies; 2) to identify key facies that can be interpreted in the context of onshore-offshore paleoenvironmental models; 3) to reconstruct the faunal succession in this thick interval of strata so as to elucidate in greater detail two key levels of faunal change associated with the global Taghanic Bioevent; and 4) to use stratigraphy and sedimentology to identify structural features that were active or present during deposition of these units. Preliminary results of our work show that most of the lower and medial parts of the Tully Formation clastic correlative succession (here in referred to as "TFCCS") between Sherburne, NY and New Lisbon, NY consist of relatively unfossiliferous strata that record the development of a structural basin (New Berlin Trough) probably centered in what is now the Unadilla Valley. Condensed units overlying regional discontinuities developed at several stratigraphic levels both in the basin and on its western flank; sediment-starvation associated with condensation led to the formation of "oolitic" chamosite under conditions not fully understood. Basin center deposits recorded dysoxic conditions and development of low diversity faunas dominated by auloporid corals and small brachiopods; eastward passage of sparsely fossiliferous deposits near New Berlin to richly fossiliferous equivalent units near Laurens reflects a shoreward basin-to-shelf transition. This contradicts the standard view that the lower and medial Tully record primarily shallow and even lagoonal conditions. Our model does vigorously support (and significantly enhances) Heckel's (1973) view of a "Tully clastic trap" controlled by structure in east-central New York. Herein, we show that typical oxic Hamilton facies ends with onset of dysoxic, highstand conditions associated with deposition of the New Lisbon Member. We exclude the upper, Tully-equivalent part of Cooper and Williams' (1935) "New Lisbon Member", which is separated from our restricted New Lisbon Member by a basal Tully erosion surface. Currently, we believe that the restricted New Lisbon succession is equivalent to the Gage Gully submember of the Windom Member, although this is still uncertain. The TFCCS contains six internal mappable discontinuities; these are, in upward-succession: a, a base-Tully (DeRuyter Bed-equivalent?) contact; b, a sub-"Laurens" contact, possibly 2 equating to the base of the Fabius Bed to the west; c, a sub-Symrna Bed disconformity traceable westward into central New York; d, a top-Smyrna flooding surface contact; e, an erosion surface flooring the West Brook Bed; and f, a diastem (base-Moravia Bed? discontinuity) above the West Brook Bed. The upper Tully, base-West Brook contact marks the greatest lowstand event with development of a prolific Hamilton faunal association characterized by diverse brachiopods, and corals, above the contact. East of Otselic, the Tully Formation contact with the overlying Geneseo Black Shale is conformable. Initial Tully Fauna incursion occurs at the base-Tully (DeRuyter Bed-equivalent?) contact at New Lisbon and Laurens.

  • Rartioter Vol
    rartioter Vol. XII, No. 1 WINTER 1 9 7 9 BLACK DOME IN 1924 The Catskill Mountains have been known to white men for three hundred years and their valleys have been settled more than a cen- tury. It would seem as if all their summits ought by this time to be easily accessible by well known trails. Yet there are a dozen or more of the higher ones, above 3500 feet, which have no trails to their summits and which are climbed only by the exploring hiker, or perhaps a bear hunter in winter. I recently found another trackless peak, Black Dome, just under 4000 feet--3990 according to the Durham sheet of the United States Geological Survey--on a week-end climb in the northern Catskills. There is no trail over it, and the only paths that reach its flanks are faded out logging roads in the valleys north and south, attain- ing heights 1500 feet below its highest point. Black Dome is the central and highest of the three peaks that make up the Blackhead Mountains, running east and west, Black Head being the easternmost, then Black Dome and the last Thomas Cole. The other two are about fifty feet lower than the Dome. South of them is the valley of the East Kill, north that of Batavia Kill. North of Black Head runs a long ridge to Acra Point, then turning west to Windham High Peak. South this ridge runs through North Mountain and Stoppel Mountain to Kaaterskill Clove. Black Head is accessible by a good trail.

  • Chapter 2 Paleozoic Stratigraphy of the Grand Canyon
    CHAPTER 2 PALEOZOIC STRATIGRAPHY OF THE GRAND CANYON PAIGE KERCHER INTRODUCTION The Paleozoic Era of the Phanerozoic Eon is defined as the time between 542 and 251 million years before the present (ICS 2010). The Paleozoic Era began with the evolution of most major animal phyla present today, sparked by the novel adaptation of skeletal hard parts. Organisms continued to diversify throughout the Paleozoic into increasingly adaptive and complex life forms, including the first vertebrates, terrestrial plants and animals, forests and seed plants, reptiles, and flying insects. Vast coal swamps covered much of mid- to low-latitude continental environments in the late Paleozoic as the supercontinent Pangaea began to amalgamate. The hardiest taxa survived the multiple global glaciations and mass extinctions that have come to define major time boundaries of this era. Paleozoic North America existed primarily at mid to low latitudes and experienced multiple major orogenies and continental collisions. For much of the Paleozoic, North America’s southwestern margin ran through Nevada and Arizona – California did not yet exist (Appendix B). The flat-lying Paleozoic rocks of the Grand Canyon, though incomplete, form a record of a continental margin repeatedly inundated and vacated by shallow seas (Appendix A). IMPORTANT STRATIGRAPHIC PRINCIPLES AND CONCEPTS • Principle of Original Horizontality – In most cases, depositional processes produce flat-lying sedimentary layers. Notable exceptions include blanketing ash sheets, and cross-stratification developed on sloped surfaces. • Principle of Superposition – In an undisturbed sequence, older strata lie below younger strata; a package of sedimentary layers youngs upward. • Principle of Lateral Continuity – A layer of sediment extends laterally in all directions until it naturally pinches out or abuts the walls of its confining basin.

  • Sulphate Balance of Lakes and Shallow Groundwater in the Vasavere Buried Valley, Northeast Estonia
    SULPHATE BALANCE OF LAKES AND SHALLOW GROUNDWATER IN THE VASAVERE BURIED VALLEY, NORTHEAST ESTONIA K. ERG Department of Mining Tallinn Technical University 82 Kopli St., 10412 Tallinn Estonia Phone: 620 38 53 Fax: 620 36 96 E-mail:[email protected] Groundwater constitutes an important component of many water resource systems, supplying water for domestic use, for industry, and for agriculture. Management of a groundwater system, an aquifer, means making such decisions as to the total quantity of water to be withdrawn annually, the location of wells for pumping and for artificial recharge and their rates, and control conditions at aquifer boundaries. Not less important are decisions related to groundwater quality. In fact, the quantity and quality problems cannot be separated. In many parts of country, with the increased withdrawal of groundwater, the quality of groundwater has been continuously deteriorating. In recent years the attention has been focused on groundwater contamination by mine water. A most important part of modelling procedure is a thorough understanding of the system, and the processes that take place in it. It is important to identify those parts of the system’s behaviour that are relevant to the considered problem, while other parts may be neglected. On the basis of this understanding, summarised as a conceptual model of the given problem, a numerical model is constructed. A groundwater flow model of the Quaternary aquifer, in eastern part of oil shale deposit area, in Vasavere buried valley, was constructed by using the conceptual model. The infiltration of contaminants grows and the Quaternary aquifer is polluted by sulphate in a large area of Vasavere buried valley.
