| Ultrahigh Pressure Metamorphic Traces Hidden in Zircons from Amphibolites of Sulu Terrane,Eastern China |
| Using the Laser Raman spectroscopy,cathodoluminescence method and electron microprobe analysis,the authors recognized coesite inclusions together with garnet, omphacite, phengite, magnesite, rutile and apatite inclusions in zircons from all amphibolite samples in pre pilot drillhole CCSD PP1 and CCSD PP2 as well as in outcrops of Sulu terrane. The mineral inclusion assemblage preserved in zircons is similar to that in the matrix of eclogites formed during the UHP metamorphism. These data indicate that amphibolites might have been formed by the retrogression of UHP eclogites in the uplifting of Sulu terrane. The research is of great significance in probing into the genetic mechanism of amphibolites and the fluid rock interaction during the tectonic uplift of Sulu terrane. |
