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 ...

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 ...

Diffusion: Obstacles and Opportunities in Petrochronology
Reviews in Mineralogy and Geochemistry, 2017Many of the approaches in petrochronology are rooted in the assumption of equilibrium. Diffusion is an expression of disequilibrium: the movement of mass in response to chemical potential gradients, and isotopes in response to isotopic gradients. It is extremely important that we be aware of how the effects of diffusion can place obstacles across our ...

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.

Significant Ages—An Introduction to Petrochronology
Reviews in Mineralogy and Geochemistry, 2017Question : Why “Petrochronology”? Why add another term to an already cluttered scientific lexicon? Answer : Because petrologists and geochronologists need a term that describes the unique, distinctive way in which they apply geochronology to the study of igneous and metamorphic processes. Other terms just won’t do.

Titanite (CaTiSiO5) is a common mineral in calc-silicates, metamorphosed igneous rocks, and calc-alkaline plutons. The mineral was first named by Martin Klaproth in 1795 for its high content of the element titanium, which had been discovered only a few years prior, and named by Klaproth for the Titans of Greek mythology.
