文摘

Metamorphic rocks in the northern Xing’an are Late Paleozoic–Mesozoic in age.

The metamorphic rocks are not basement of the so-called Precambrian blocks.

Jurassic (170–160 Ma) metamorphism is firstly identified from the metamorphic rocks.

The Jurassic metamorphism was likely linked to the Mongol–Okhotsk collision.
