| 摘要: |
| 根据已有的研究资料,分析桂西辉绿岩型金矿的物质来源、形成机制及矿床特征。认为桂西辉绿岩的金丰度普遍较低(约为2.4 5×10-9),不具备形成金矿的物质来源。桂西辉绿岩型金矿属改造型金矿,金主要来源于基性岩浆对围岩(热水沉积岩)的混熔改造。桂西辉绿岩出露区或内接触带附近具硅化、褐铁矿化的断裂破碎带具有寻找辉绿岩型金矿的找矿前景,特别是广西那坡辉绿岩出露区颇有寻找辉绿岩型金矿的潜力。 |

| Abstract: |
| The previous research data are used to analyze material source,formation mechanism and characteristics in mineral deposit of the gold mine of diabase in the west of Guangxi,southern China.The richness of gold in the diabase is lower,roughly 2.45×10-9.That means no material source to form gold mine.The type of gold mine of the diabase belongs to a reforming type of gold mine.The gold is from the melting reform of the bedrock to the country rock (the hydrothermal sedimentary rock).There is a mineral foreground for seeking the diabase type gold mine in the siliconization and limonitization fault zone in the open areas and nearby inner belts of the diabase in the west of Guangxi,particular in the open areas of Napo. |
