The Argun terrane is a rock unit in Transbaikalia and Mongolia, located in the Mongol-Okhotsk Fold Belt.
[1] It is connected to the metamorphic complexes of the Siberian craton in the northern region, which is characterized by a narrow strip of mylonites.
[1] Dating using detrital zircon sourced from Proterozoic igneous and metamorphic rocks determined that the lower boundary is 549-570 million years old.
Subduction-related setting is hinted by the poorly sorted and slightly rounded rock clasts and interlayered gravelites.
[3] The chemical and physical conditions of Mesozoic igneous rocks with metallogenic specialization in Cis-Argun region are similar to those of the Great Kingan Belt.
