Fe-(Cu) skarn, hosted in Lower Carboniferous submarine bimodal volcanic and clastic rocks of the Yamansu Formation, mainly consisting of andesitic tuff, andesitic tuff breccia, limestone, potash-keratophyre, potash-porphyritic felsite, and felsite in the vicinity of iron-rich mineralization. The skarns developed between limestone, which may be intercalated with andesitic breccia, tuff, agglomerate, basaltic andesite, and andesitic tuff, and rhyolitic tuff. A sub-volcanic, pyroxene-bearing diorite porphyry is present 500 m southwest of the orebodies, where the deposit area is cut by a northerly-trending fault. Although other granitoids are not exposed at the surface, a gravity survey indicates that an additional buried pluton may lie beneath the deposit area.
