Morphological Specification Of Chinianella Scheympflugi Hofmann, 1994, A Late Jurassic (?Earliest Cretaceous) Dasycladalean Alga Of The Western Tethyan Domain, Felix Schlagintweit

Studia UBB Geologia

The dasycladalean alga Chinianella? scheympflugi was described by Hofmann (1994) from the Tithonian of the Ernstbrunn Limestone of Lower Austria. This alga, so far unreported besides its type-locality, is reported from the Late Jurassic of Poland, the Northern Calcareous Alps of Austria, Crimea (Ukraine), and Greece (Parnassos Zone). Facies are well-agitated outer platform habitats (peri-reefal and back-reefal facies). The cylindrical thallus consists of three parts: a sterile Salpingoporella-like basal part (stalk), a fertile Chinianella-type main portion and a short sterile top part. The transition from the stalk to the main thallus portion is well marked and abrupt. The stratigraphic range …

New Data On Facies Development And Micropaleontology Of The Eastern Margin Of The Getic Carbonate Platform (South Carpathians, Romania): Case Study Of Mateiaş Limestone, Ioan I. Bucur, Daniela Beles, Emanoil Sasaran, Constantin Balica

Studia UBB Geologia

Mateiaş Limestone represents a lithostratigraphic unit included in the Braşov Series, which is a component of the eastern end of the Getic Nappes’ cover (the Getic carbonate platform). The study of the Mateiaş Limestone in Hulei-Mateiaş-Măgura area has evidenced three main facies, and five microfacies types. The Kimmeridgian (possibly also Early Tithonian) age of the Mateiaş Limestone has been assigned based on a microfossil association identified in thin sections. The regional framework, as well as their sedimentological and micropaleontological features point to the deposition of these limestones on shelf margin and slope environments; the succession in the studied area corresponds …

Late Jurassic–Early Cretaceous Foraminifera From Štramberk-Type Limestones, Polish Outer Carpathians, Daria Ivanova, Boguslaw Kolodziej

Studia UBB Geologia

Foraminifera studies were carried out on the Štramberk-type limestones which occur as pebbles to small boulders (exotics) within the uppermost Jurassic–Palaeogene flysch deposits of the Polish Outer Carpathians. The studies were focused on foraminifera from (1) reef and peri-reef facies, and (2) lagoonal algal-foraminiferal facies. The paper deals with 34 species (including 8 in open nomenclature) representing 30 genera, 22 families, 14 superfamilies, 11 suborders, and 7 orders. A more precise age determination has been obtained for 30 exotics, representing a Tithonian (mostly) to Valanginian age. Foraminiferal assemblages from at least two exotics suggest a Valanginian age as indicated by …

Classification And Fertility Of Soils In The Big South Fork National River And Recreation Area Based On Landscape Position And Geology, Ryan H. Blair

Masters Theses

The Big South Fork National River and Recreation Area encompasses more than 50,585 hectares (125,000 acres) of the Cumberland Plateau along the border of Tennessee and Kentucky. Highly dissected and steep terrain have made accessibility to much of the park limited, thus little work has been done to investigate the formation of these soils. Seven native soil profiles were selected for chemical and physical analysis representing Pennsylvanian-aged acidic sandstone and shale geology and landforms. The objectives of this study included the characterization of selected native profiles by physical and chemical analysis, as well as classification using US Soil Taxonomy, to …

Central New York Varve Chronology: A Suggestion For Quaternary Geologists, Thomas Bradley Walker

Thomas Bradley Walker

Work done to build a chronology of deglaciation using varves has been the focus of a number of researchers in New England for many years. The locations employed to build their timeline have been quite useful to date. However, New England is not the only place in the Northeast conducive to studying the last deglaciation of North America. The discovery of a set of ice proximal varves in an ancient glacial lake, now a swamp, in Oswego County, central New York, has shown that some locations outside of New England would be suitable for similar studies. The land having been …

A Speleothem-Based High Resolution Reconstruction Of Climate In Southeastern Brazil Over The Past 4,100 Years, Brandon L. Taylor

Masters Theses 1911 - February 2014

Isotopic investigations of speleothem CR1 from Cristal Cave in southeastern Brazil have established a high-resolution record of climate change extending 4,100 years prior to sample collection in 2007. A total of 14 subsamples were collected from CR1 for U/Th age determination. ICP-MS analysis yielded very precise ages with analytical errors (2σ) averaging ± 13 years. An initial growth rate of .062 mm y-1 for the first 2860 years is followed by a rate of .08 mm y-1 for the remaining growth period allowing for sampling of δ18O at sub-decadal resolution. Stable isotope analyses show a large range of δ18O values …

An Inventory And Condition Survey Of The Western Australian Part Of The Nullarbor Region, P A. Waddell, A K. Gardner, P Hennig

Technical Bulletins

The inventory and condition survey of the Western Australian part of the Nullarbor region, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 2005 and 2007, describes and maps the natural resources of the region. This survey report provides a baseline record of the existence and condition of the area's natural resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The Nullarbor region has …

Geology And Structure Of The Rough Creek Area, Western Kentucky, William D. Johnson Jr., Howard R. Schwalb

Bulletin--KGS

The Rough Creek area is a rectangular area about 113 mi east to west and 35 mi north to south encompassing about 3,900 mi² in west-central and western Kentucky. The Ohio River delineates most of the western border with Illinois and locally also part of the northern border with Indiana. The northeast corner of the area is about 27 mi southwest of Louisville. The principal cities are Owensboro and Henderson.

The Precambrian basement has been penetrated in only two wells in western Kentucky at depths somewhat greater than 14,000 ft. Basement is projected to underlie much of the area …
