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。
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.
主要组成矿物为硬玉、霓辉石、镁纳闪石、蓝透闪石、镁角闪石、阳起石、石英、钠长石、金红石和榍石。
Mineral constituents consist mainly of jadeite, aegirine - augite, magnesio - riebeckite, winchite, magnesio - hornblende, actinolite, quartz, albite, rutile and sphene.

晚期的钠质角闪石构成了现存片理，可能与后期构造变形有关。
While, the sodium amphibolites in the later stage compatible with the present foliation, might be related to the structure deformation.
