| 中文摘要:大厂矿田内的龙头山锡矿床和铜坑锡矿床是广西丹池锡多金属成矿带中最具有代表性的矿床。其烃类组分的宏观和微观特征及配分规律显示出其成矿的复杂性及物质的多来源性。龙头山矿区花岗岩中烃类组分的含量明显高于矿石及其围岩,其烃类组分的来源和性质明显有别于矿体和围岩,成矿作用与有机流体关系密切。铜坑矿区花岗岩中烃类组分的含量明显不同于各个矿体,并且,不同地质体内烃类组分的含量变化不一,成矿流体在来源和性质上存在较为复杂的联系,成矿流体具有明显的深源特征。 |

| Abstract:The Longtoushan ore deposit and Tongkeng ore deposit constitute two most typical ore deposits in the Danchi tin-polymetallic ore belt. The macroscopic and microscopic characteristics of hydrocabon components show complexity and multisourcen ature of ore-forming materials in the two typical ore deposits. In Longtouashan area,hydrocarbon components of granite and ore bodies show remarkable differences,and the mineralization was closely related to organic fluids. Things seem more complex in Tongkeng area,where the hydrocarbon components of granite are obviously different from those of ore bodies|and hydrocarbon components vary differently in different ore bodies. It is inferred that the fluid was of multisource nature and the mineralization was related to the magma and strata. |
