The Bayankhongor ophiolite zone is one of the largest ophiolite complexes in Mongolia, extending approximately 300 km in length and up to 20 km in width. It marks a major suture zone formed by the closure of a Neoproterozoic oceanic rift basin and subsequent collision of tectonic blocks. This Neoproterozoic complex comprises a well-preserved tectonic assemblage of oceanic lithosphere components, including serpentinite mélange, pillow basalts, gabbros, and variably serpentinized peridotites. Ultramafic units host seams of podiform chromitites containing platinum-group minerals.
