The Gurvansaikhan Ridge ophiolite crops out as a belt up to ~25 km long and ~2.5 km wide, hosted within sedimentary-volcanic sequences. The Cambrian ophiolite consists of a wide range of ultramafic and mafic rocks. The rocks yielded U–Pb zircon ages of 520–511 Ma. Ultramafic rocks host podiform chromitites.
