The Khairkhan massif, located in the central Lake Zone of western Mongolia, is a lenticular body about 18 km long and 5 km wide. This Middle Cambrian layered and zoned intrusion, emplaced in an island arc setting (suprasubduction, syn-collisional setting). Dunite, troctolite and olivine gabbro form the central part of the massif whereas non-olivine gabbro and amphibole gabbro occur along the margins. The rocks were derived from a high-alumina, low-Ti magma source. The massif hosts four mineralized horizons which are 3–5 m thick and extend for up to 4 km.
