For the purpose of studying the stability of phengites geobarometry in retrograde metamorphism.
因而,经历了富流体活动的退变质作用后,岩石中的多硅白云母残斑已不能完全保存其形成时的压力信息。
The main mineral assemblage of the garnet-amphibolite from the first part in CCSD-PP2 is amphibole, garnet, biotite and albite, which resulted from retrograde metamorphism.
镜下鉴定和激光拉曼测试结果表明预先导孔(CCSD-PP2)第一段榴闪岩的主要矿物为角闪石、石榴石、黑云母和钠长石,是榴辉岩退变质作用的产物。
A geochemical study of elemental migration from granulite-facies rocks to amphibolite-facies rocks during retrograde metamorphism has been carried out through the analyses both of petrochemical data for whole rocks and electronic microprobe data for essential minerals (e.
