Electron Microprobe Petrochronology
Reviews in Mineralogy and Geochemistry, 2017The term petrochronology has increasingly appeared in publications and presentations over the past decade. The term has been defined in a somewhat narrow sense as “the interpretation of isotopic dates in the light of complementary elemental or isotopic information from the same mineral(s)” (Kylander-Clark et al. 2013).

Reviews in Mineralogy and Geochemistry, 2017
Thermal ionization mass spectrometers, or TIMS, were developed by the pioneers of mass spectrometry in the mid-20th century, and have since been workhorses for generating isotopic data for a wide range of elements. Later-developed mass spectrometric techniques have many advantages over TIMS, including higher spatial resolution with in situ techniques ...

Reviews in Mineralogy and Geochemistry, 2017
The inspiration for this volume arose in part from a shift in perception among U–Pb geochronologists that began to develop in the late 1980s. Prior to then, analytical geochronology emphasized progressively lower blank analysis of separated accessory mineral aggregates (e.g., Krogh 1982; Parrish 1987), with results generally interpreted to reflect a ...

Petrochronology of Himalayan ultrahigh-pressure eclogite
Geology, 2013The timing and nature of the India-Asia collision, Earth’s largest ongoing continent-continent collisional orogen, are unclear. Ultrahigh-pressure metamorphism of Indian continental margin rocks is used as a proxy for initial collision because it indicates subduction of India.

Zircon Petrochronology of the Kışladaǧ Porphyry Au Deposit (Turkey)
Economic Geology, 2022Abstract Porphyry deposits typically occur in subduction-related arcs but have more recently also been described in postsubduction, collisional to extensional back-arc settings. These different tectonic environments not only might imply different genetic processes but also seem to result in different metal endowments (e.g., Au rich ...

Petrochronology of oxidized granulites from southern Peru
Journal of Metamorphic Geology, 2019AbstractSapphirine–quartz granulites from the Cocachacra region of the Arequipa Massif in southern Peru record early Neoproterozoic ultrahigh‐temperature metamorphism. Phase equilibrium modelling and zircon petrochronology are used to quantify timing and pressure–temperature (P–T) conditions of metamorphism.

Deformation and metasomatism recorded by single-grain apatite petrochronology
Geology, 2022Abstract The timing and processes of ductile deformation and metasomatism can be documented using apatite petrochronology. We integrated microstructural, U-Pb, and geochemical analyses of apatite grains from an exhumed mylonitic shear zone in the St.

Laser-ablation split-stream ICP petrochronology
Chemical Geology, 2013Abstract Laser-ablation split-stream (LASS) analysis—high-speed, high spatial-resolution, simultaneous isotopic and elemental analysis—enables petrochronology at a new level, through the interpretation of isotopic dates combined with elemental abundances and/or isotopic tracers.

Petrochronologic constraints on Paleozoic tectonics in southern New England
2023ABSTRACT The Appalachian Mountains were formed through multiple phases of Paleozoic orogenesis associated with terrane accretion. The timing, tempo, and significance of each event in New England are obscured by overprinting, the limits of geochronologic tools, and differences between lithotectonic domains.
