Book Synopsis Structural Evolution and Geochronology of the Southeastern Llano Uplift, Central Texas by : Joseph Floyd Reese
Download or read book Structural Evolution and Geochronology of the Southeastern Llano Uplift, Central Texas written by Joseph Floyd Reese and published by . This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Llano Uplift, central Texas, exposes Middle Proterozoic crystalline rocks that were deformed and metamorphosed during Grenville orogenesis. New U-Pb zircon geochronology from the Valley Spring Gneiss and Packsaddle Schist in the southeastern Llano Uplift, combined with previous data, demonstrate that several map units contain disparately aged constituents. Three new units are differentiated: the Comanche Creek Gneiss, Coal Creek Formation, and Inks Lake Gneiss. Results show that younger Packsaddle Schist lies in structural contact above older Valley Spring Gneiss. Also, zircons in a Valley Spring Gneiss unit are the oldest yet found in the uplift (~1360 Ma). Their age is consistent with those of the Western Granite-Rhyolite Terrane. The map distribution of U-Pb data shows four age suites of rocks of distinct tectonic origin. A 1248-1244 Ma Packsaddle Schist is structurally wedged between 1270 Ma northerly Valley Spring Gneiss, and southerly ~1300 Ma Big Branch Gneiss and older Coal Creek units. Younger meta-intrusive rocks intrude the metamorphic pile. Grenville orogenesis is constrained to have occurred between 1215 Ma and 1098 Ma. Detailed structural mapping shows that these rocks record a polyphase deformational history progressing from 1) NE-directed, collision(?)-related ductile thrusting and shortening (D2), to 2) regional-scale polyphase folding (D3, D4, D5), indicating continued N- to NE-directed contraction, to 3) late-stage, post-collisional N-S extension. D2 deformation was partitioned, with ductile thrust zones accommodating NE-directed shearing, and intensely folded units representing shortened and flattened zones. Strong development in different areas of different post-D2 fold generations suggests that these areas are in regional-scale fold hinges. Thus, the southeastern Llano Uplift consists of multiple generations of regional-scale folds. N-S extension is recorded by quartz vein fibers oriented normal to a WNW-striking, variably dipping extensional crenulation cleavage and subparallel to the stretching direction of boudins. The timing and orientation of these structures is consistent with late-stage N-S extension. The Llano Uplift represents the metamorphic core of a Grenville-age continental collision zone. Island-arc, accretionary complex, oceanic, and arc-flank/continental-slope assemblages were contracted between continental-scale blocks and emplaced onto North America's southern margin. Ductile thrusting and polyphase folding accommodated deformation of this material and its tectonic transport continentward. Increasing pressure-temperature conditions of dynamothermal metamorphism toward the orogenic core are attributed to greater crustal thickening related to continental margin underthrusting and tectonic stacking

Available in PDF, EPUB and Kindle. Book excerpt: The volume reviews current knowledge of transform margins and addresses fundamental questions for future research. Furthermore, the articles look at principal factors that influence the dynamics, kinematics and thermal regimes of continental break-up at transform margins and cover geophysics (bathymetry, seismic, gravity and magnetic studies), structural geology, sedimentology, geochemistry, plate reconstruction and thermo-mechanical numerical modelling.
Book Synopsis The Pennsylvanian-early Permian Bird Spring Carbonate Shelf, Southeastern California by : Calvin H. Stevens
Download or read book The Pennsylvanian-early Permian Bird Spring Carbonate Shelf, Southeastern California written by Calvin H. Stevens and published by . This book was released on 2007 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Bird Spring Shelf in southeastern California, along with coeval turbidite basins to the west, records a complex history of Pennsylvanian and Early Permian sedimentation, sea-level changes, and deformation along this part of the western North American continental margin. In this work we describe and figure the fusulinids, including several new species, and establish detailed correlations between deposits of the shelf and the flanking basins. We then use these correlations to reconstruct the depositional history, paleogeography, and deformational history of the region. This work adds significant detail to existing interpretations of the late Paleozoic as a time of major tectonic instability on the continental margin of southeastern California as it changed from a relatively passive margin, which had persisted through most of the Paleozoic, to an active convergent margin that would characterize the Mesozoic."--Publisher's website.

Book Synopsis Architecture of the Central Brooks Range Fold and Thrust Belt, Arctic Alaska by : John S. Oldow
Download or read book Architecture of the Central Brooks Range Fold and Thrust Belt, Arctic Alaska written by John S. Oldow and published by Geological Society of America. This book was released on 1998-01-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 17 papers presented here introduce results on geological and geophysical research centred largely along a North-South transect through the central Brooks Range of Arctic Alaska. Investigations centre on a descripton of the rocks and their tectonic evolution from the foreland to the hinterland of the orogen, the geometry and kinematics of contractional and extensional structures, regional and local stratigraphic relations, thermochronology, and the deep crustal structure of the Brooks Range and parts of the North Slope, and descriptions of the major lithotectonic assemblages, composing the orogenic belt.
