The Khondalite Belt is a Paleoproterozoic tectonic belt in the Western Block of the North China Craton. It consists mainly of high-grade metamorphosed Al-rich sedimentary rocks, also named as the ‘Khondalite Series’. The vast majority of detrital zircons from the Khondalite Series rocks have ages dominantly at 2.2–2.0Ga, but their provenances become an enigma due to lack of available synchronous magmatic...
The Ti-in-zircon thermometer is a newly established, single-mineral trace element thermometer, which has been successfully used to estimate the peak and post-peak temperatures of high-grade metamorphic rocks. Here the revised Ti-in-zircon thermometer and in situ SIMS U-Pb dating are applied to detrital and metamorphic zircons of pelitic granulites from the Qianlishan-Helanshan Complex. The SIMS U-Pb...
