The Ulaan Tolgoi massif, dated at ~298 Ma, is an elongated rift-related intrusion about 700 m long and 400 m wide, hosted by Ordovician (~495 Ma) granites. It is a multiphase intrusion composed of older peralkaline syenites, which constitutes the southern portion of the intrusion and younger peralkaline granites, which cover an area of about 300 × 400 m in the northern part of the massif.
