The Tanyaokou copper-zinc-lead deposit is located within the Mesoproterozoic Langshan-Zha'ertai-Bayun Obo ore belt of Inner Mongolia, 30 km SW of the Dongshenmiao Mine and approximately 350 km west of Hohhot (#Location: 40° 58' 00"N, 106° 50' 00"E).

The deposit is hosted by a Mesoproterozoic meta-sedimentary, cataclasitc-carbonate sequence of the Langshan Group which includes mainly dolomite (locally containing barite), carbonaceous slate, phyllite and schist on the Langshan-Zha'ertaishan aulacogen along the northern margin of the North China Platform.

Intercalated grey to light brown K feldspar-leucogranulites and granulites with blastoporphyritic and blasto-glomeroporphyritic textures as well as blasto-amygdaloidal structures, are believed to have been developed from protoliths of potassic bimodal-volcanic rocks.

The host sequence has been folded into gently dipped anticlines and synclines.

The several ore lenses are concordant with the host meta-sediments, closely associated with the intercalated meta-volcanics, and occur as massive and banded sulphides which include pyrite with lesser sphalerite and chalcopyrite.

The sulphide minerals are zoned from pyrite and chalcopyrite at the base, passing up to chalcopyrite and sphalerite with increasing but minor galena.
