| 中文摘要: |
| 云南个旧锡矿东矿区塘子凹凹陷带岩体内的蚀变岩型铜多金属矿床形成于富碱、氧化环境中,钾长石化是重要的找矿标志之一,多种金属元素可以综合利用。蚀变分带比较特别,主要的蚀变带钾长石化带与绿帘石化带相互交替出现,可能与热液的多期(次)性有关。通过对蚀变岩以及矿体采样分析结果的定量计算,得出有关常量元素、主要成矿元素及其伴生元素的迁移规律,为今后的找矿方向提供了依据。 |
| 英文摘要: |
| The newly discovered altered rock-type copper-polymetallic deposit in the rock body of Tangzi'ao depression zone is formed under alkali-rich and oxidization setting.K-feldspar is one of the prospecting marks.Multi-metal elements can be comprehensively recovered.The deposit is special in alteratiion zoning,i.e.the alternated K-feldsparization and epidotization that may be related to episodic hydrothermal fluid pulses.By quantitative calculation of altered rock and ore samples,the author find out the migration laws of the constant elements and the main ore-forming elements and their associated elements,which provide a basis for prospecting in the future. |
