The MLYRV metallogenic belt witnessed Neoproterozoic (1000–850 Ma), and Cambrian to Early Triassic sedimentation as well as Mesozoic intra-plate deformation induced by two major tectonic
domains (Tethys and paleo-Pacific) with deep crust–mantle interaction (Chang et al., 1991; Zhai et al., 1992; Pan and Dong, 1999;Mao et al., 2006).
