Book excerpt: "Extending from Colorado, USA, on the north to the state of Chihuahua, Mexico, on the south, the Rio Grande rift divides the Colorado Plateau on the west from the interior of the North American craton on the east. This volume focuses on the Rio Grande rift's upper crustal basins and is organized geographically with study areas progressing from north to south. Nineteen chapters cover a variety of topics, including sedimentation history, rift basin geometries and the influence of older structure on rift basin evolution, faulting and strain transfer within and among basins, relations of magmatism to rift tectonism, and basin hydrogeology"--Provided by publisher.

Book excerpt: Deformation of the Earth’s crust happens at a multitude of scales, ranging from submicroscopic to planetary. Tectonics explores structures and processes from regional to global, differentiating itself from the material covered in most structural geology textbooks. Moores and Twiss emphasize basic principles and methodologies of tectonics, embracing the time-honored perspective of using present processes to understand the past. Comprehensive in scope and detail, coverage includes the effects of plate motions and reconstructions and the resultant structures associated with active rift, transform, and subduction boundaries as well as triple junctions and collision zones; deformations of both the ocean basins and the continents; and orogenic belts. Moores and Twiss present tectonics as an open-ended field of study in which assumptions can be challenged and interpretations changed. The authors emphasize the use of models as a means of understanding observations and putting them in context to maintain a distinction between what we know from observing the Earth and what we infer from interpretation.

Available in PDF, EPUB and Kindle. Book excerpt: For 35 years, strong reflected phases from the sill-like, midcrustal Socorro Magma Body (SMB) have been observed on microearthquake seismograms recorded in the central Rio Grande rift, New Mexico. In 1979 the lateral extent of the SMB was estimated at 1700 km2 by mapping reflection points for 220 observed SzS arrivals. We have remapped the magma body using 697 PzP, 2169 SzP, and 2589 SzS reflections observed on seismograms recorded between 1975 and 1995 by New Mexico Tech seismic networks. These data indicate that the SMB covers an area greater than 3400 km2. By comparing the distribution of observed reflection points with the distribution of all possible reflection points, limits can be set for the northern and southern boundaries of the SMB. The ~80 km north-south extent of the SMB falls just inside an ~100 km north-south range of enhanced seismicity near Socorro. This area, the Socorro Seismic Anomaly (SSA), covers ~5000 km2 and has the same elliptical shape as the outline of the SMB based on observed reflection points. The close spatial relation between the SSA and the midcrustal magma body along their northern and southern boundaries suggests that the observed seismicity can be used to place limits on the eastern and western boundaries of the magma body. Using the distribution of earthquakes within the SSA over the last 34 years, the maximum east-west extent of the SMB is

Book excerpt: In the course of the hundreds of Rio Chama rafting trips that we've logged during the last 30 years, none of us has ever had a bad trip. Such is the magic of the Rio Chama. No matter the weather, the water level, the season, the crowded Big Eddy boat ramp on a blistering Sunday afternoon, or even the coffee forgotten at home, the Rio Chama remains "The People's River." Its stunning beauty, plus its exceptional camping, user-friendly whitewater, and mostly predictable flows, combine to create one of the Southwest's premiere, multi-day, river running experiences.The spectacular, towering canyon walls of the Wild & Scenic section through the remote Chama River Canyon Wilderness is New Mexico's own "Grand Canyon." The geology of the Rio Chama is so exceptional that this river is ideally suited for a river guide with a geological theme. And so, following the release of the Rio Grande geologic river guide in 2011, we turned our (part-time) attention to the Rio Chama. Although most Rio Chama recreation is focused on the El Vado to Big Eddy stretch, thedecision was easily made to include the entire boatable section, from the highlands in Colorado to the confluence with the Rio Grande, as each section of the river displays its own visual spectacles and assortment of adventures. Plus, the geology is magnificent and diverse along the entire length of the river.

Available in PDF, EPUB and Kindle. Book excerpt: Faults zones are three-dimensional structures that separate distinct hanging wall and footwall lithologic units and commonly exhibit mechanical and hydrological properties distinct from protolith. As such, they exert a fundamental control on a wide variety of societally relevant geological processes, from the transport and/or trapping of ore-bearing fluids and hydrocarbons to the generation of earthquakes. Fluids commonly mediate the structural development of fault zones, particularly through physical and chemical alteration of fault rocks during diagenesis and mechanical processes such as hydrofracturing. Collectively, these processes can lead to substantial variations in fault hydromechanical properties and thereby a fault zone's response to later fault slip and fluid flow events. Very little previous research has attempted to provide a holistic examination of this interplay between faults and fluids in the crust, which requires recognizing and exploring the relationship between tectonics, fault rock mechanics, fluids, and diagenesis. This dissertation attempts to fill this gap in our knowledge by examining fluid-fault interactions in the Rio Grande rift of New Mexico. Chapter 1 describes the results of research that utilized calcite cements in fault damage zones as a geochemical record of fluid source to evaluate tectonic controls on fluid migration during the development of the Rio Grande rift. These data show that the distribution of faults, bedrock, and syntectonic sediments of varying hydrological and mechanical properties results in a predictable spatial and temporal distribution of fault-zone fluid flow pathways during basin extension. Chapter 2 evaluates the role of syntectonic calcite cementation in the development of fault-zone architecture and permeability structure in the Loma Blanca fault zone, Socorro Basin, NM. It additionally demonstrates that cementation and proximity to zones of structural complexity such as fault relays exert a profound impact on the location and magnitude of fluid flow over time within developing normal fault systems. Chapter 3 presents U-Th geochronology and stable isotope data from syntectonic calcite veins in the Loma Blanca fault zone which constrain earthquake recurrence intervals over >400 ka. These data provide a critical first test of competing earthquake frequency models for intraplate faults.

This book was released on 1995 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because the Rio Grande Rift is one of the best seismically instrumented rift zones in the world, studying its seismicity provides an exceptional opportunity to elucidate the active tectonic processes within continental rifts. Beginning on 29 November 1989, a 15 square km region near Bernardo, NM, produced the strongest and longest lasting sequence of earthquakes in the rift in 54 years. Our research focuses on the Bernardo swarm which occurred 40 km north of Socorro, New Mexico in the axial region of the central Rio Grande rift. Important characteristics concerning hypocenters, fault mechanisms, and seismogenic zones are discussed.
