The Jianglang Tectonic Dome (JTD) lies on the Songpan –Garze Orogenic Belt (SGOB), the eastern margin of the Tibetan Plateau. As a part of the SGOB, Muli-Yanyuan Foreland Thrust Zone(LYFTZ) separates it from the western of Yangtz block. In the northern margin of the JTD, As thermal metamorphism and metasomatism, skarn was formed in the Tiechanghe granite and Permian strata boundary surface. Wulaxi W-Mo deposit occurs in the skarn. The ore type comprises skarn and quartz vein types. Both scheelite and molybdenite are dominant ore-forming minerals in the deposit.
