The peak metamorphic minerals are garnet, omphacite,phengite and rutile with temperature of~500℃,pressure of~2.3Gpa.On the basis of geochemical analysis,the content of SiO2 in the eclogite ranges from 46.68%to 50.24%,Na2O+K2O 3.10~4.21%,and high REE with enriched LREE, LREE/HREE of 2.83~6.06.The REE pattern and trace element spidergram are similar with those of ocean island basalt,according with the blueschist from Longmucuo -Shuanghu suture zone.The protolith of the eclogite and blueschist are OIB,and they aremaybe the result of subduction of Permian OIB in central Qiangtang area.

The ultramafic rocks outcropped at the Altyn region are all harzburgites. Remant grains of primary minerals have melted residual texture and elastic deformation texture under high temperature and pressure. The whole-rock analyses show their low TiO〓 contents (0.01~0.04%), low Al, Ca and high MgO contents and wide Mg〓 range (89.35~95.57). Rare earth patterns have two types, namely tabacco pipe-shped and LREE-shaped, of which the former is often seen. The chondrite-nomalized Yb values of these analyses are all lower than 1. The spinels have low Ti and high Cr content and most spinels have Cr# higher than 60. All of the above characteristics show that the ultramafic rocks in the Altyn fault zone are components of metmorphic peridotites of ophiolite from depleted mantle source and most ophiolites from this zone belong to supra-subduction zone type ophiolite with a few mid-ocean ridge basalt type.
