Orebodies occur in a fault near the axial region in the southern limb of the Jinjinghe-Hujiamiao inverted secondary anticline in the southern limb of the Hongyansi-Heishan composite syncline. Host rocks are dolomitic rocks in the middle and upper parts of the Devonian Qingshiya Formation. Their spatial distribution is obviously controlled by an interlayer fracture-fissure zone near the axial region in the steeply dipping southern limb of an anticline. Ores are dominantly of nodular and stockwork types and the feature of epigenetic mineralization is very pronounced.
