摘　　要：好力宝铜钼矿床属与燕山期隐伏的隐爆角砾状斜长花岗斑岩和碎裂次石英斑岩有关的热液脉状和斑岩型矿床.铜钼矿体受隐爆角砾岩筒和岩体控制,矿化产在蚀变隐爆角砾岩和硅化带中.今后的找矿方向应侧重于对斜长花岗斑岩与围岩接触带和碎裂次石英斑岩中化探异常和低阻高极化异常地段的探索.Haolibao copper-molybdenum deposit is of hydrothermal vein and porphyry type related to the Yanshanian crypto-explosive breccia-plagioclase granite porphyry and cataclastic sub-quartz-porphyry. The copper-molybdenum ore bodies are controlled by the crypto-explosive breccia pipe and rock body. The mineralization occurs in the altered crypto-explosive breccia and silicified belt. The further exploration should be focused on the contact zone between the plagioclase porphyry granite and wallrocks, as well as the cataclastic sub-quartz-porphyry with geochemical abnormity and low resistance-high polarization anomaly.
