Armored Mud Balls And Friable Sand Megaclasts From A Complex Early Pleistoceme Alluvial Fill, Southwestern Morrill County, Nebraska, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Armored mud balls and friable sand megaclasts occur in exposures of a complex Early Pleistocene sand and gravel alluvial fill which caps a strath terrace in southwestern Morrill County, Nebraska. The mudballs are limited to a tributary arroyo. The sand megaclasts occur in sediments deposited along a trunk stream. It is possible that the sand megaclasts were transported to the site in a frozen condition.

The Geology Of Ophiolitic And Adjoining Rocks Of Chagnon Mountain, Southern Quebec, Janet M. Harris

Geology Theses and Dissertations

Chagnon Mountain is located near the southern end of the Baie Verte-Brompton Line in the Eastern Townships of southern Quebec. The lithologic units in the area of study, from west to east and going up structure, are: gabbro, quartz-diorite, diabase, volcanics, the St. Daniel Formation and the Peasley Pond Conglomerate of the Glenbrooke Group. All these rocks have been metamorphosed to the greenschist facies. Contacts between the plutonic rocks are irregular and gradational indicating only one parent magma. Diabase dikes are present in the diabase unit and in the volcanics indicating the dikes acted as feeders to the volcanics. Geochemical …

Structural Analysis Of Deformed Carboniferous Strata, Mispec Beach, Southern New Brunswick, Lauren Magin Bradley

Geology Theses and Dissertations

Mispec Beach, New Brunswick is a coastal exposure of deformed Carboniferous sedimentary rocks. Late Paleozoic deformation in the region is thought to have occured in a restraining bend in the Cobiquid - Chedabucto fault.
Within this exposure, two main generations of deformation are recognized. The first deformation is associated with slaty cleavage development, pebble elongation, and the formation of quartz veins. The second generation structure is a moderately developed crenulation cleavage. The diversity of structures present at this outcrop allows for a qualitative determination of the principal axes of stress and strain associated with the first generation structures.

Chatham Fault Zone, Old Chatham-East Chatham, New York: Mesostructures And Microstructures: Their Spatial And Age Relationships, Jorge Mora M.

Geology Theses and Dissertations

Detailed studies in rocks of Mettawee (Late Precambrian? to Early Cambrian) and Walloomsac (Middle Ordovician) slates between Old Chatham and East Chatham, New York, have shown that these rocks were intensely deformed during the Taconic orogeny and a later deformation event(?). Two generations of structures are clearly recognized in the area. The first generation (G1) includes tight west-verging folds whose axial plane foliation is the regional foliation slaty cleavage (S1). These structures are considered synchronous with the regional metamorphism of the Taconic orogeny and correlative with those structures belonging to the D2 deformation event proposed by Ratcliffe (1979) and Rowley …

Provenance Study Of The Middle Ordovician Sandstones Of New York And Western Vermont, Stephen A. Tanski

Geology Theses and Dissertations

Medial Ordovician rocks exposed in westernmost New England and eastern New York State include thick sequences of marine sandstones which are part of a belt extending from Newfoundland to Tennessee. A petrographic study was made of 237 samples distributed across the entire outcrop belt (approx. 250 km. north-south along strike and 190 km. east-west across strike).
Two distinct types of sandstone are recognized, the oldest, and most widespread, is a deep water lithic wacke deposited by turbidity currents and found interbedded with shale (flysch). The younger sandstone is found only in the southeastern part of the study area and is …

Some Aspects Of Deformation Fabrics Along The Highland/Lowland Boundary, Northwest Adirondacks, New York State, Peter C. Hall

Geology Theses and Dissertations

The Geology of the Whippoorwill Corners Area, NW Adirondacks, NYS
In the northwestern Adirondack Mountains of New York State lies a 110 km long, 0-5 km wide topographic and lithologic boundary which divides the Adirondack Highlands from the Northwest Lowlands. Structurally this boundary is apparently a highly strained zone of intensely foliated and lineated rocks. Within the zone mineral grains are highly recrystallized and of fine grain size with respect to rocks outside the zone, quartz becomes undulose, and mineral assemblages frequently exhibit retrograde characteristics. Despite the apparent high strain no demonstrable offset may be seen across the zone. Furthermore, …

Dissertations and Theses

Over 1150 m of middle to late Eocene nonmarine arkose, lithic arkose, mudstone, and siltstone, referred to here as the Chambers Creek beds, are int~r.stratified with, and overlain by over 1600 m of late Eocene-Oligocsne(?) andesitic volcaniclastic and subordinate volcanic rocks assigned to the Ohanapecosh Formation, in a dissected structural high in the southern Washington Cascade Range, about 18 km south-southeast of the town of Packwood.

Conservation and Survey Division: Faculty and Staff Publications

Preface

The computer brightened the 1970s considerably by giving researchers a tool for storing, retrieving and manipulating electronically sizable blocks of literary material on a single subject. which would otherwise have cost researchers years of scholarly investigation to bring together. It was in such a propitious moment mat we set out to assemble this state bibliography as an aid to scholars, researchers. scientists, teachers, writers, editors, and decision makers in the earth sciences, universities, and all levels of government.

As we collected, compiled, and checked citations for this bibliography, we relied heavily on the following standard sources that have indexed …

Cluster Analysis Of Grain Size Parameters From A Beach Ridge Complex, Cape Henry, Virginia, Amy T. Robbins, G. Richard Whittecar

OES Faculty Publications

Cape Henry is a Holocene beach ridge complex at the mouth of the Chesapeake Bay. Analyses of cross-cutting relationships visible on aerial photographs divide the complex into five geomorphic zones. Low, arcuate beach ridges, ornamented in places with small dunes, characterize the four oldest zones. The youngest zone consists of large irregular-shaped dunes which bury the margins of all older zones. Locations of 102 samples taken from 1 m depths on ridge crests were based upon a random stratified sampling grid covering all of Cape Henry. The use of half-phi size data generated standard sediment parameters. Weighted-pair cluster analyses of …

Geology Of The Fondo Negro Region, Dominican Republic, J. Calvin Cooper

Geology Theses and Dissertations

Detailed geologic mapping of the Fondo Negro-Sierra de Martin Garcia region of the Southwestern Dominican Republic establishes that this area is part of a broad and diffuse Northern Caribbean plate boundary zone (PBZ). Faulting in the study area is predominantly left lateral strike-slip, with secondary compression (thrusting) causing both substantial, and rapid, uplift of the region. Folding associated with the wrench faulting affects rocks of all ages in the field area from Paleocene limestones to Quaternary alluvial fans.
New stratigraphic designations are proposed for mappable litho-units in the area, and these are correlated with Hispaniola stratigraphy in general based on …
