These data suggest that the granulite facies metamorphism lasted for about 27 Ma and was related to crustal thickening associated with the Early Paleozoic continental collision between the Qilian and Qaidam blocks, and to subsequent thermal relaxation and exhumation.

这些年龄结果显示麻粒岩相变质作用持续了大约27Ma,这可能与早古生代祁连地块与柴达木地块碰撞作用所引起的地壳加厚和后来的热松驰有关。

The granulite facies were resulted from the regional high-temperature metamorphism with medium pressure. The metamorphism evolution was the retrogressive metamorphism with approximate isobaric cooling ( IBC) and counter clockwise PTt path.

麻粒岩相是中压区域高温变质作用的产物,变质作用的演化为退变质、近等压冷却(IBC)反时针型的PTt轨迹。
