中文摘要:
      隐爆角砾岩筒的成岩作用方式可分为底侵隐爆和侧向隐爆,不同方式形成的隐爆角砾岩筒,其控矿特征不尽相同,并可能形成不同的矿床类型组合。在地质勘查工作中,要根据不同类型的隐爆角砾岩筒,有针对性地寻找相关类型矿床。在底侵隐爆形成的隐爆角砾岩筒的深部可能会存在斑岩型矿床,但在侧向隐爆形成的隐爆角砾岩筒的深部,由于其底部与围岩直接接触,表现为“无根”, 因此,不存在斑岩型矿床的可能。通过研究,认为祁雨沟矿田内隐爆角砾岩筒的成岩作用方式为侧向隐爆,隐爆角砾岩筒表现为“无根”角砾岩筒,为残缺的斑岩成矿系统,在隐爆角砾岩筒的深部不存在斑岩型矿床的可能。
英文摘要:
      The diagenesis of breccia tubes crypto-explosive can be divided into bottom-invaded or lateral ones. With diverse ore-controlling characteristics, dissimilar crypto-explosive breccia tubes are formed, and different ore types may be combined. During geological exploration work, we should follow diverse types of crypto-explosive breccia tubes , and by targeting find out related types of ore deposits. There might be Porphyry deposit in the deep of bottom-invading breccia pipe. But in the deep of breccia tubes by lateral crypto-explosive, the bottom of which contact directly with surrounding rocks, performing as “rootless”. Therefore, there can’t be any porphyry deposit. After study, I think the diagenesis mode of breccia pipes in Qiyugou mining field is lateral crypto-explosion, the bottom of which is direct contact with the wall rock, called as “rootless” breccia pipes. It is impossible to form porphyry deposits in the bottom of breccia pipes crypto-explosion, and incomplete porphyry mineralization system.
