Petrochronology is a rapidly emerging branch of Earth science that links time (ages or rates) with specific rock-forming processes and their physical conditions. It is founded in petrology and geochemistry, which define a petrogenetic context or delimit a specific process, to which chronometric data are then linked. This combination informs Earth’s petrogenetic processes better than petrology or geochronology alone. This volume and the accompanying short courses address three broad categories of inquiry. Conceptual approaches chapters include petrologic modeling of multi-component chemical and mineralogic systems, and development of methods that include diffusive alteration of mineral chemistry. Methods chapters address four main analytical techniques, specifically EPMA, LA-ICP-MS, SIMS and TIMS. Mineral-specific chapters explore applications to a wide range of minerals, including zircon (metamorphic, igneous, and detrital/Hadean), baddeleyite, REE minerals (monazite, allanite, xenotime and apatite), titanite, rutile, garnet, and major igneous minerals (olivine, plagioclase and pyroxenes). These applications mainly focus on metamorphic, igneous, or tectonic processes, but additionally elucidate fundamental transdisciplinary progress in addressing mechanisms of crystal growth, the chemical consequences of mineral growth kinetics, and how chemical transport and deformation affect chemically complex mineral composites. Most chapters further recommend areas of future research.

Isotope chronology has developed over the last 100 years and has advanced in response to the requirements of geological research. Despite the technical, instrumental, and methodological advances in geochronology, accurate and precise dating of geological materials, processes, and events is still needed. This book highlights new findings on tectonochronology, and contributes to the theory and methods of several important scientific topics, such as the formation of syn-kinematic minerals, development of systematic methods of dating deformation and their use, criteria for dateable minerals and methods for direct and precise dating, the relationship between mineral formation/evolution and isotope chronology, influences of strain and fluid on isotopic diffusion, and improved understanding of stress, fluid, and temperature in earth sciences. This book includes cases from Chinese geology that refer to dating of deformation, tectonic evolution and environmental change. These methods can be applied to other earth science topics and geological studies worldwide.

Microstructural Geochronology Geochronology techniques enable the study of geological evolution and environmental change over time. This volume integrates two aspects of geochronology: one based on classical methods of orientation and spatial patterns, and the other on ratios of radioactive isotopes and their decay products. The chapters illustrate how material science techniques are taking this field to the atomic scale, enabling us to image the chemical and structural record of mineral lattice growth and deformation, and sometimes the patterns of radioactive parent and daughter atoms themselves, to generate a microstructural geochronology from some of the most resilient materials in the solar system. First compilation of research focusing on the crystal structure, material properties, and chemical zoning of the geochronology mineral archive down to nanoscale Novel comparisons of mineral time archives from different rocky planets and asteroids and their shock metamorphic histories Fundamentals on how to reconstruct and date radiogenic isotope distributions using atom probe tomography Microstructural Geochronology will be a valuable resource for graduate students, academics, and researchers in the fields of petrology, geochronology, mineralogy, geochemistry, planetary geology, astrobiology, chemistry, and material science. It will also appeal to philosophers and historians of science from other disciplines.

Deformation and arc magmatism are two fundamental processes of tectonism. Deformation is expressed as fault systems and shear zones that evolve to accommodate plate motion and arc magmatism is expressed as voluminous intrusive suites. Major questions remain, however, as to the relationship between deformation and arc magmatism. My dissertation investigates plutons and shear zones using structural geologic, geophysical, and petrochronologic tools, to observe how they are expressed temporally and spatially to assess feedbacks between arc magmatism and deformation.Chapter one used gravity investigations to observe modern magma emplacement and storage at Laguna Del Maule. Laguna Del Maule is a volcanic field (LdMVF) within a modern magmatic arc, where rhyolitic volcanism is associated with strike-slip faults. Our new density model of the broader LdMVF captured what we interpret as at least two magma bodies at different stages of maturity. From these data, we concluded that multiple discrete plutons presently exist in the LdMVF. Chapters two, three, and four used structural and geochronological methods to investigate how pluton emplacement is connected to ductile shear zones by investigating exhumed examples of magmatic arcs emplaced during oblique convergence. Chapter two was a collaborative study with Dr. Claire Harrigan at Boise State University. Together we used petrochronology to investigate high-temperature crustal strain partitioning and localization on the micro- to macro-scale using the western Idaho shear zone (WISZ), west-central Idaho. By integrating the geochronometric, geochemical, and microstructural titanite record, we documented the local preservation of titanite related to magmatic and deformation processes. Importantly, our results provide a date for the onset of deformation in the WISZ, confirming tectonic interpretations of WISZ deformation as a separate event from terrane suturing. Chapter three and four expanded this work to the Cretaceous intrusive suites of Nevada in the central United States Cordillera. Chapter three is a first order investigation of middle and Late Cretaceous granodiorites of northwest Nevada. Chapter four expands on this original dataset to track the spatial-temporal patterns of pluton emplacement and deformation using fabrics preserved within the Sahwave Range intrusive suite and the Power Line intrusive complex. We determined that the Sahwave Range intrusive suite and Power Line intrusive complex record two distinct dextral transpressional deformation events, ~100 Ma and ~88 Ma, and provide a missing link between the Sierra Crest shear zone in the Sierra Nevada batholith and the western Idaho shear zone in the Idaho batholith.

In Earth evolution, mountain belts are the loci of crustal growth, reworking and recycling. These crustal-scale processes are unravelled through microscale investigations of textures and mineral assemblages of metamorphic rocks. Multiple episodes of metamorphism, re-equilibration and deformation, however, generally produce a complex and tightly interwoven pattern of microstructures and assemblages. Over the last two decades, the combination of advanced computing and technological capabilities with new concepts has provided a vast array of novel petrological tools and high-resolution/high-sensitivity techniques for microanalysis and imaging. Such novel approaches are proving fundamental to untangling the enigma represented by metamorphism with an unprecedented level of detail and confidence. As a result, the first decade and a half of this century has already seen the tumultuous development of new research avenues in metamorphic petrology. This book aims to provide a timely overview of the state of the art of this field, of newly developed petrological techniques, future advancements and significant new case studies.
