In the Ospa ultrabasic-basic massif, serpentinites associated with nephrite mineralization occur as two distinct branches: the North Dunzhugur and the South Il’chir. These serpentinite units are interpreted as remnants of a single ophiolitic nappe, referred to as the Dunzhugur island-arc ophiolite. Prolonged residence in an ancient oceanic environment allowed for the preservation of a complete ophiolite sequence through a series of geological formations. The emplacement of this ophiolite was controlled by the obduction of the Dunzhugur island arc onto the Gargan microcontinent during the early Neoproterozoic (ca. 800 Ma), which facilitated the development of a serpentinite mélange acting as a tectonic lubricant. Subsequent phases of collision and thrusting led to the fragmentation, folding, and erosion of the ophiolite, ultimately shaping the framework of the Gargan microcontinent.
