Tangzhangzi Au-ploymetallic deposit is situated within the northern margin of North China Craton, eastern Yanshan orogenic belt. Sedimentary rocks outcroping in the orefield are the Changzhougou Formation consist of primary pebbly sandstone, sandstone and quartzite and the Chuanlinggou Formation comprises shale, sandy shale and siltstone.The NE striking normal faults control the occurrence of the intrusive rocks. Au-ploymetallic mineralization shows a close relationship with Cryptoexplosive breccia and quartz veins. Middle Jurassic granite porphyry locates in the cryptoexplosive breccia and presents as a single dyke striking NE direction. Colossal massive clasts of Sinian diabase are common in the cryptoexplosive breccia pipe, which indicates that diabase generally preceded formation of the cryptoexplosive breccia. Close spatial and textural relationship suggest that granite porphyry and cryptoexplosive breccia are genetically related and they formed contemporaneously.
