| 摘 要： | 中国超大型金矿床有5种类型:绿岩型、变质碎屑岩型、沉积岩型、火山岩型、花岗岩型。其中以绿岩型为主。成矿物质主要来自赋矿围岩。超大型金矿床主要属"规律型",服从大中小型矿床统一的成矿规律,与大中小型矿床一起成带成片产出。中国东部一些成矿条件较好的成矿带,勘探和开采深度比较浅,选择一些成矿条件好的中小型矿床,加强深部及外围找矿勘探,是当前寻找超大型金矿床经济、快速、行之有效的途径。中国西南、西北地区的沉积岩型、火山岩型金矿床的成矿条件好,有可能形成超大型金矿床。

| Abstract: | There are five kinds of superlarge gold deposits in China,including greenstone,metamorphic clastic rock,sedimentary rock,volcanic rock and granite types.The greenstone is the major type.The metallogenic materals mainly came from the host wallrock.Superlarge gold deposit accord to the united metallogenic regularity of large、middle and small gold deposit and occured with them as belt and sheet.In the East of China,the depth of exploration and mining are more shallow for some metallogenic belts with better ore-forming condition.choosing some middle and small deposit with well ore-forming condition and strengthening the exploration in depth and periphery are the better way to seek for superlarge gold deposit. |
