Book Description
"The Appalachians constitute one of Earth's major tectonic features and have served as a springboard for innovative geologic thought for more than 170 years. This volume contains 36 original papers reporting the results of research performed throughout nearly the entire length and breadth of the Appalachian region, including all major provinces and geographical areas. Memoir 206 was designed to commemorate the (near-)fortieth anniversary of the publication of the classic Studies of Appalachian Geology volumes that appeared just prior to the application of plate tectonic concepts to the region. Contributions concerning structural evolution, sedimentation, stratigraphy, magmatic processes, metamorphism, tectonics, and terrane accretion illustrate the wide range of ongoing research in the area and collectively serve to mark the considerable progress in scientific thought that has occurred during the past four decades."--pub. desc.

PROTEROZOIC ASSEMBLY OF NORTH AMERICA: INSIGHT FROM THE INTERACTIONS OF DEFORMATION, METAMORPHISM AND MAGMATISM IN THE SOUTHWESTERN UNITED STATES Robert Alexander Hunter, Ph. D. Cornell University One of the major goals of the geoscience community is to develop an accurate tectonic history of North America. Understanding how our continent evolved through time has numerous implications for our ability to develop accurate models of the tectonic evolution of continents - how they form, deform, and break. The interactions of deformation, metamorphism, and plutonism, three fundamental geological processes at work throughout the evolution of continents, record information that can be used to better understand the mechanisms and events that have shaped our continent. This dissertation employs metamorphic petrology, structural geology, geochemistry and geothermobarometry to interrogate the interactions of deformation, metamorphism and plutonism on multiple scales across the southwest United States. On a microscope scale, this dissertation shows that deformation and metamorphism can work in a positive feedback loop, facilitated by solution mass transfer, to localize both deformation and metamorphism, producing areas of high strain that have more closely approached metamorphic equilibrium. This result informs our understanding of crustal behavior at mid-crustal depths during orogenesis. On the mountain range scale, this dissertation combines petrographic analysis, structural geology, geochemistry and geothermobarometry to show that metamorphism in the Tusas and Picuris Mountains of northern New Mexico is consistent with one metamorphic event following a pressure-temperature-time trajectory consistent with progressive loading during the formation of a fold and thrust belt. This result informs our understanding of the tectonic history of North America, and has implications for the petrogenesis of aluminosilicate triple-point rocks in the region. Finally, on a continental scale, this dissertation uses previously published geochronologic data to identify spatial patterns in the age of igneous bodies across the southwest United States. These results were used to characterize mesoproterozoic tectonism and develop a model for melt production of these plutons. This result informs not only our understanding of crustal growth and rejuvenation during orogeny, but also provides a comprehensive dataset and novel approach that may both be employed in future research.

Belt Basin: Window to Mesoproterozoic Earth
Author: John S. MacLeanPublisher: Geological Society of America
ISBN: 0813725224
Category : History
Languages : en
Pages : 400
Book Description
With its thickness of more than 15 km of strata, covering some 200,000 km2, the Belt basin displays one of the planet's largest, best-exposed, most accessible, and best-preserved sequences of Mesoproterozoic sedimentary and igneous rocks. This volume focuses on research into this world-class province; kindles ideas about this critical era of Earth evolution; and covers aspects of the basin from its paleontology, mineralogy, sedimentology, and stratigraphy to its magmatism, ore deposits, geophysics, and structural geology.
