This book was released on 2015 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: North-northeast extension and bimodal magmatism during early Rio Grande rifting is recorded by the emplacement histories of two suites of dikes and associated plugs at Faulkner Canyon. Whole-rock geochemistry and 40Ar/39Ar data suggest that alkalic trachybasalts (34.7 +/- 1.1 Ma) and trachydacites (35.96 +/- 0.09 ma) were emplaced first and were followed by the emplacement of two petrogenetically distinct groups of calc-alkaline magmas consisting of basaltic andesite and andesite. Major and trace element compositions from these two suites indicate that Ne-normative trachybasalts (Nb/Ba = 0.057- 0.026) were likely derived from the asthenosphere and evolved to QTz-normative trachydacitic compositions by assimilation and fractional crystallization (AFC) of mid-lower crust. Calc-alkaline magmas (Nb/Ba = 0.006-0.013), however, were likely sourced from an enriched lithospheric mantle source and evolved independently. Spatial distribution of hypabyssal units suggest that magmas were emplaced as a series of laccolithic bodies that may have been elongated from a previously exsting zone of structural weakness possibly associated with the Texas Lineament. Although previous works suggest that early Rio Grande rift extension was oriented generally E-W during hypabyssal emplacement, localized stresses from the intrusions initially deformed the overlying Eocene Palm Park Formation into a broadly folded E-W trending anticline and sub-parallel joints that were filled by alkaline and calc-alkaline magmas.

This book was released on 1998-01-01 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the geometry, kinematic development, and origin of regional segmentation structures within the basin and range province of Western North America. Contributions range from analysis of individiual structures to broad regional syntheses, including a map of basin and range structures and tilt domains. Several papers discuss the implications of regional segmentation structures in assessing seismic hazards, hydrocarbon and mineral resources, and ground-water supplies.
