The Hg-Au deposit in Jiaoli is situated in the San-Dan metallogenic belt, mercury orebody assumed lentoid, lenticular and nervation and occurred on the fracture cracked belt, ore bearing wall rock is the grainstone of a suit of slope facies of Guoyang formation, Lower Ordovician. Beside cinnabar, ore mineral includes pyrite, arsenopyrite, sphalerite, realgar and native gold, sometimes native mercury can be found. Gangue mineral includes calcite, dolomite, barite, quartz and so on. In the form of native gold and isomorphism, gold existed in chalcedony, pyrite, arsenopyrite and other gold carrier mineral. The wall-rock alteration of orebody is intense. The alteration that concerned with mercury deposit includes realgar mineralization, moderate silicification, pyritization, arsenopyrite mineralization and chalcedonization, has deep relation with the gold mineralization. The metallogenic geological condition is good and the prospecting potential is big.
