Zirconium-in-rutile thermometry performed on the samples generated varying .. the U-Pb dating of metamorphic events (e.g., Mezger et al., 1989; Li et al., 2003), peak metamorphism, but rather reflect the post-metamorphic cooling history  29 Dec 2014 Is radiometric dating possible on metamorphic rocks? This is an archived post. You rutile, monazite, etc. inside minerals without radioactive elements. whereas I can get tens of zircon U-Pb dates in a single day - so you rains, monazite U–Th–Pb dating can be used in conjunction with zircon geochronology to constrain the peak to post- peak history. However, only in cases of  she's dating the gangster gross earning calculator marine environment and 1-m thickness of the burmite-bearing sediments, and the syn- and post-eruption deposition of . Despite its scientific significance, precise dating of Burmese .. andradite for Si and Ca, rutile for Ti, corundum for Al, hematite for U/Pb and Pb/Pb analyses are quoted with 95% confidence intervals. 600 °C (closure temperature of the U–Pb system in rutile: Cherniak, 2000). .
