Diamond deposit, located in the Fuzhou Basin in Eastern Liaoning uplift of the North China Platform. The basement rock consists of Archean granite and gneiss that is overlain by Paleozoic and Mesozoic sedimentary rock in a N-NE-trending synclinorium. Kimberlite occurs along EW striking faults in the basement and NE-striking faults in overlying rocks. The major Tanlu fault zone is the main ore-controlling structure.

Eighteen kimberlite pipes and 58 kimberlite dikes occur in the area. The pipes are complicated and irregular. Eight of them have economic grades, averaging 50 mg/m3. A maximum grade of 308 mg/m3 occurs in pipe No. 50. The kimberlite dikes occur along fractures that strike N-NE and dip at 70° to 80°. They are parallel to each other and eight of them, which are intensely carbonate-altered, bear diamonds. The richest of these dikes is no. 69, with a grade of 327 mg/m3. The diamond hardness is more than 88,000 kg/mm2. Most diamonds are transparent and with a strong adamantine luster.
