摘 要：Felsic granulites in continental collision zone can provide valuable insights into geological processes of continental deep subduction(Massone,2003;Perraki and Faryad,2014),but their metamorphic evolutions are still poorly constrained due to extensive retrograde transformations and associated erasure of pristine fabrics and mineral *** better understand the evolution of these rocks,two samples(A1501 and A761)from the south Altyn Tagh(SAT)of northwest China were selected for detailed
