| 中文摘要: |
| 角砾岩型金矿床是一种重要的金矿床类型。中国角砾岩型金矿床分为四种主要类型:与小侵入岩体有关的角砾岩型金矿床;与斑岩系统有关的角砾岩型金矿床;与火山-次火山岩有关的角砾岩型金矿床;产在不整合面或沉积间断面上的角砾岩型金矿床。文章在对每类矿床实例进行矿床地质特征描述后,分析了中国角砾岩金矿床的找矿前景并指出寻找角砾岩型金矿床最有希望的地区。 |
| 英文摘要: |
| More attention should be paid to breccia-hosted Au deposits. Such deposits in China are divided into 4 subtypes, ie porphyry breccia, volcanic- subvolcanic breccia, small intrusion-related breccia and unconformity or depositional break breccia Au deposits. Geological features of each subtype are described. Ore-searching prospect are analysed and targets in china for such depolits are point out in this paper. |
