Huff 4 Department of Geology, University of Cincinnati, Cincinnati, OH 45221 USA 5 Email: [email protected] 6 Keywords: K-bentonite, bentonite, tephra, explosive volcanism, volcanic ash 7 Abstract 8 Pyroclastic material in the form of altered volcanic ash or tephra has been reported and described 9 from one or more stratigraphic units from the Proterozoic to the Tertiary. This altered tephra, 10 variously called bentonite or K-bentonite or tonstein depending on the degree of alteration and 11 chemical composition, is often linked to large explosive volcanic eruptions that have occurred 12 repeatedly in the past. K-bentonite and bentonite layers are the key components of a larger group of 13 altered tephras that are useful for stratigraphic correlation and for interpreting the geodynamic 14 evolution of our planet. Bentonites generally form by diagenetic or hydrothermal alteration under 15 the influence of fluids with high Mg content and that leach alkali elements. Smectite composition is 16 partly controlled by parent rock chemistry. Studies have shown that K-bentonites often display 17 variations in layer charge and mixed-layer clay ratios and that these correlate with physical 18 properties and diagenetic history. The following is a review of known K-bentonite and related 19 occurrences of altered tephra throughout the time scale from Precambrian to Cenozoic. 20 Introduction 21 Volcanic eruptions are often, although by no means always, associated with a profuse output 22 of fine pyroclastic material, tephra. Tephra is a term used to describe all of the solid material 23 produced from a volcano during an eruption (Thorarinsson, 1944).

  • Notes on the Mountain Limestone and Lower Carboniferous Rocks of the Fifeshire Coast from Burntisland to St Andrews
    ( 385 ) XVI.—Notes on the Mountain Limestone and Lower Carboniferous Rocks of the Fifeshire Coast from Burntisland to St Andrews. By the Rev. THOMAS BROWN, Edinburgh. (Read 17th April 1860.)

Six Upper Limestones, A to F. Myalina Beds. Corals. Petrified Trees. Shells. Marine Beds. Crustacea. Fossils. Fish. V. Results—The Two Groups defined. Tuberculated Fish. Introduction. In this paper I shall first refer to the circumstances under which the follow- ing observations were made. I had gone in the autumn of 1856 for a few weeks to Elie on the Fife coast, and was induced, as a means of relaxation and exercise in the open air, to pay some attention to the geology of the neighbourhood, resuming for a brief interval what was once a favourite pursuit. About a mile to the east of the village, I found a stratum well deserving attention—a thin bed of limestone—dipping in- land a little beyond the cliff on which stands the ruined Castle of Ardross. The fossil shells which it contained were of unusual form, and beautifully preserved ; there were fish remains of two or three species, and a small group of crustaceans still more remarkable. Among the fish I thought I could detect the large scales of an Irish species—the Holoirtijchius Fortlockii—and among the crustaceans there were the valves of Dithyrocaris, a genus particularly characteristic of the Irish beds. At once the question arose whether these fossils might not serve as links connecting this Ardross bed with the Irish series.

  • Plan for the Recovery of Desert Bighorn Sheep in New Mexico 2003-2013
    PLAN FOR THE RECOVERY OF DESERT BIGHORN SHEEP IN NEW MEXICO 2003-2013 New Mexico Department of Game and Fish August 2003 Executive Summary Desert bighorn sheep (Ovis canadensis mexicana) were once prolific in New Mexico, occupying most arid mountain ranges in the southern part of the state. Over-hunting, and disease transmission from livestock are 2 primary reasons for the dramatic decline in bighorn sheep numbers throughout the west during the early 1900s. In 1980, desert bighorn were placed on New Mexico’s endangered species list. From 1992-2003, approximately 25% of bighorn were radiocollared to learn causes of mortality driving this species towards extinction. Approximately 85% of all known-cause non-hunter killed radiocollared individuals have been killed by mountain lions. Despite the lack of a native ungulate prey base in desert bighorn range, mountain lion populations remain high, leading to the hypothesis that mountain lions are subsidized predators feeding on exotic ungulates, including cattle. Lack of fine fuels from cattle grazing have resulted in a lack of fire on the landscape. This has lead to increased woody vegetation which inhibits bighorn’s ability to detect and escape from predators. Bighorn numbers in spring 2003 in New Mexico totaled 213 in the wild, and 91 at the Red Rock captive breeding facility. This is in spite of releasing 266 bighorn from Red Rock and 30 bighorn from Arizona between 1979 and 2002. Several existing herds of desert bighorn likely need an augmentation to prevent them from going extinct. The presence of domestic sheep and Barbary sheep, which pose risks to bighorn from fatal disease transmission and aggression, respectively, preclude reintroduction onto many unoccupied mountain ranges.

  • NORTHERN ARIZONA PROVINCE (024) by W.C
    NORTHERN ARIZONA PROVINCE (024) By W.C. Butler INTRODUCTION This province covers about 59,000 sq mi, mostly in the southwestern part of the Colorado Plateau. Significant geologic features include the Grand Canyon, Kaibab Arch, Mogollon Highlands transition zone, Monument Uplift, Defiance Uplift, Black Mesa Basin, Holbrook Basin, and southern edges of the Kaiparowits and Blanding Basins. The stratigraphic section shown for northeastern Arizona has demonstrated the highest petroleum potential in Arizona. See Wilson (1962), Butler (1988a), and Dickinson (1989) for synopses of the province's geology and evolution. The lithologically and structurally complex basement of the Colorado Plateau area evolved from northwest-younging Proterozoic terranes sequentially accreted onto the Archean craton. As much as 12,000 ft of Middle and Late Proterozoic strata is preserved in possible rift-aulacogen depositional settings in central Arizona. Thick, unmetamorphosed, organic-rich Late Proterozoic strata deposited in backarc basins or continental lakes of north-central Arizona and south-central Utah have good petroleum potential. The plateau area, as a passive Paleozoic plate margin and buffered Mesozoic retro-arc platform, has been remarkably tectonically stable during Phanerozoic time. The area is characterized by blanket Paleozoic strata, as much as 6,000 ft thick, consisting of mostly shallow marine clastics and carbonates showing numerous disconformities. These strata accumulated during transgressions and regressions from both the northwest and southeast, onlapping and thinning toward the trans-continental arch – a northeast-trending positive area extending from the northeast into central Arizona. Convergence between North and South American tectonic plates, with reactivation of basement blocks, during the late Paleozoic created the plateau's fault-bounded basins and uplifts.

Licensed under the Creative Commons Attribution- NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/ licenses/by-nc-nd/4.0/ 1 Abstract Permian strata from the Tieqiao section (Jiangnan Basin, South China) contain several distinctive conodont assemblages. Early Permian (Cisuralian) assemblages are dominated by the genera Sweetognathus, Pseudosweetognathus and Hindeodus with rare Neostreptognathodus and Gullodus. Gondolellids are absent until the end of the Kungurian stage—in contrast to many parts of the world where gondolellids and Neostreptognathodus are the dominant Kungurian conodonts. A conodont changeover is seen at Tieqiao and coincided with a rise of sea level in the late Kungurian to the early Roadian: the previously dominant sweetognathids were replaced by mesogondolellids.

Appendix 2.1: Balaton Highlands and Bükk Mountains Investigated sites. The Permian-Triassic succession of Balaton Highlands comprises part of the ALCAPA megaunit (Kóvacs and Haas, 2010) and is represented by Permian fluvial red sandstones and Triassic shallow marine rocks. The Lower Triassic succession in the Balaton Highlands is divided into four formations: the Kóveskál Dolomite Formation, Arács Marl Formation, Hidegkút Formation and Csopak Marl Formation (Figure A2.1). These formations paraconformably overlay the Permian Baltonfelvidék Formation and are capped by the Middle Triassic Aszòfo Dolomite Formation (Haas et al., 2012). Field visits (June 2012) to the Balaton Highlands (Figure A2.2) recorded 5m of the Kóveskál Formation at Balatonfüred; 15m at Balataonálmadi; and 1m of the Csopak Marl Formation at the Sóly section. Broglio Loriga et al. (1990) studied the biostratigraphy of the entire succession, but their data, were acquired from a trench that is no longer exposed (János Haas, pers. comm.) and their collections were not available for study (Renato Posenato, pers.
