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 ...

Titanite petrochronology of the Pamir gneiss domes: Implications for middle to deep crust exhumation and titanite closure to Pb and Zr diffusion [PDF]
Tectonics, 2015 ©2015. American Geophysical Union. All Rights Reserved. The Pamir Plateau, a result of the India-Asia collision, contains extensive exposures of Cenozoic middle to lower crust in domes exhumed by north-south crustal extension.

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 ...
