This is China’s largest prime diamond deposit. The ore field is located in the southern Liaoning Peninsula. The ore field formed on the concave Fuzhou-Dalian platform on the Sino-Korean para-platform and is composed of 18 kimberlite tubes and 58 kimberlite veins. Three kimberlite tubes in the lower/root part of a volcanic passage are of industrial value. The isotopic ages of the tubes are from 341 million to 463 million years old, and the tubes are from the Caledonian tectonic period. The kimberlite is composed mainly of olivine, phlogopite, almandine, ilmenite and diamond (Fig. 1).
