Lens-shaped syenite-carbonatite complex, intruding a metamorphic terrain composed of Late Proterozoic metaspilites, keratophyres and corresponding agglomerates and tuffs to the south, and Devonian carbonaceous sericite schists interbedded with dolomitic limestone and marble to the north. The complex consists of a variety of lithologies, including syenite, albitite, syenite and albitite porphyries, calcite carbonatite, biotite-calcite carbonatite and ankerite carbonatite.
The deposit was discovered in 1962 and explored in 1971 and 1980, but has not been mined. Located near Miaoya village.
