At the Tiechagou carbonatite, two distinct types of carbonatites are observed, which are the calcio-carbonatite and magnesio-carbonatite. In both carbonatites, olivine is commonly altered to serpentine. Iron mineralization is characterized by massive magnetite ores that are generally found as layers in the carbonatite body. Magnetite and ilmenite are the most abundant Fe-bearing minerals in the deposit.
