The giant Diyanqin'amu Mo deposit is a porphyry system in Great Hingan Range, China. The porphyry Mo system yields zircon U–Pb and molybdenite Re–Os ages of 159–156 Ma.. The causative porphyry was crystallized from highly-evolved I-type granitic magmas. The Diyanqin'amu deposit is an Endako- or continental arc-type porphyry Mo system. The deposit originated from southeastward subduction of the Mongol–Okhotsk plate.
