Tseel terrane has WPB and MORB-type protoliths. Darvi and Han-Hohey areas have VAB and MORB-derived protoliths.Tsagaan Shuvuut terrane has protolith of IAB. Zavkhan terrane has VAB and MORB-derived protoliths, which is divided into two zones, Urgamal and Zavkhan-Mandal. Geochronology of mafic metamorphic rocks from Zavkhan area shows 903±15 Ma and 830±37Ma. VAB-type rock has age of 904±9.3 Ma.
