Abstract: 海南抱伦金矿所处的大地构造位置为华南褶皱系五指山褶皱带的西南部,位于NW向尖峰岭-吊罗深大断裂与EW向九所-陵水深大断裂之间.区内构造以断裂为主.矿区地层较为简单,仅出露下志留统陀烈组下段、陀烈组中段及白垩系,主要分布在矿区外围的西部和东部.本区酸性-中酸性岩浆侵入活动很发育.海南抱伦金矿的石英中发育大量流体包裹体,主要为原生包裹体,还有少量次生包裹体.流体包裹体体积一般较小,长轴为4 ~12 μm,短轴为2~6 μm,绝大多数包裹体单轴长度<6 μm.包裹体类型大多为富液两相包裹体,纯液相包裹体次之,少部分为CO2三相包裹体.海南抱伦金矿床是由中-低温成矿流体成矿作用形成的.成矿流体属于低密度流体.
