Apatite: a U-Pb thermochronometer or geochronometer? [PDF]
Lithos, 2018 Abstract Apatite is an accessory mineral that is frequently found in both igneous and clastic sedimentary rocks. It is conventionally considered to be characterized by a closure temperature range between 375 and 600 °C and hence has been employed to address mid-temperature thermochronology questions relevant to the reconstruction of thermal events in

U-Pb memory behavior in Chicxulub's peak ring — Applying U-Pb depth profiling to shocked zircon [PDF]
Chemical Geology, 2019 The zircon U-Pb system is one of the most robust geochronometers, but during an impact event individual crystals can be affected differently by the passage of the shock wave and impact generated heat. Unraveling the potentially complex thermal history recorded by zircon crystals that experienced variable levels of shock and heating, as well as ...
