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 chaptersinclude petrologic modeling of multi-component chemical and mineralogic systems, and development of methods that include diffusive alteration of mineral chemistry.Methods chaptersaddress four main analytical techniques, specifically EPMA, LA-ICP-MS, SIMS and TIMS.Mineral-specific chaptersexplore 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.

Volume 48 of Reviews in Mineralogy and Geochemistry represents the work of many authors whose research illustrates how the unique chemical and physical behavior of phosphate minerals permits a wide range of applications that encompasses phosphate mineralogy, petrology, biomineralization, geochronology, and materials science. While diverse, these fields are all linked structurally, crystal-chemically and geochemically. As geoscientists turn their attention to the intersection of the biological, geological, and material science realms, there is no group of compounds more germane than the phosphates.

Volume 66 of Reviews in Mineralogy and Geochemistry is based on a two day short course entitled Paleoaltimetry: Geochemical and Thermodynamic Approaches held prior to the Geological Society of American annual meeting in Denver, Colorado (October 26-27, 2007). This meeting and volume were sponsored by the Geochemical Society, Mineralogical Society of America, and the United States Department of Energy.
