Abstract: The Dahongshilazi gold deposit is a newly discovered cryptoexplosive breccia type gold deposit in western Liaoning. Using integrated geological， geophysical and geochemical exploration methods combined with prospecting engineering， the cryptoexplosive breccia body， i.e.， the mineralized alteration zone， was discovered and 4 ore bodies were delineated. The ore bodies are controlled by NE-trending faults and ring faults， and all occur in the cryptoexplosive breccia body at the contact zone between the andesite of the Middle Jurassic Tiaojishan Formation and the rhyolite of the Lower Cretaceous Yixian Formation. The Lower Cretaceous Yixian Formation strata， cryptoexplosive breccia， NE-trending faults and ring faults， rhyolite porphyry dikes， and wall rock alterations such as pyritization， silicification， and carbonatization are the main geological prospecting criteria； Au-Ag-As-Pb-Zn-Cu-Sb-Mo soil comprehensive anomalies are geochemical prospecting criteria； low resistivity and high polarization characteristics are important geophysical prospecting criteria. The 4 ore bodies are not closed in strike and dip， showing potential for further prospecting. Through comprehensive geological prospecting， the deposit scale is expected to reach medium to large.
