Abstract
The kyanite quartzite from the ultrahigh-pressure metamorphic belt in the eastern Dabie Mountains is composed mainly of quartz, kyanite, talc and epidote, which contains a typical mineral assemblage of white schist. It suffered an eclogite facies metamorphism ofP = (2.4 ±0.3) GPa andT = 630 ° C together with coexisting eclogite. The protolith may be an aplite replaced by high-pressure fluid of eclogite facies.
