| 摘 要： | 北一、南六矿体是海南石碌铁矿床最主要的2个铁矿体,赋矿围岩同为二透岩,铁矿石主要为赤铁矿加少量磁铁矿.研究两矿体赋矿围岩和富铁矿石的地球化学特征,比较其物质组成差异性,可以为本矿床深部和外围找矿提供有用信息.研究表明,北一、南六2个矿体二透岩、富铁矿的主量元素、微量元素及稀土元素配分曲线差异明显;北一矿体二透岩除CaO和Co含量低于南六矿体样品外,其余氧化物及微量元素含量均高于南六矿体样品;北一矿体二透岩及富铁矿有Eu弱负异常,南六矿体二透岩及富铁矿Eu正异常;所有样品均表现Ce的弱负异常和轻稀土相对亏损、重稀土相对富集的特征.研究结果表明两矿体成矿环境或受后期热液影响不同.

| Abstract: | Beiyi orebody and Nanliu orebody are the two main orebodies of Shilu iron deposit in Hainan Province, with high research value, ore-bearing wall rocks being the diopside-tremolite rocks and iron ores being mainly composed of hematite and tiny magnetite. By studying geochemical characteristics of wall rocks and ores of two orebodies and comparing their material composition differences, we hope that it could provide some useful information for prospecting in depth and periphery of deposit. Two orebodies have pronounced differences. The distribution patterns of main elements and trace elements of Beiyi＇ s and Nanliu＇ s high-grade Fe ore samples of two orebodies are pronounced; except that CaO and Co of Beiyi orebody＇s diopside-tremolite rocks are less than Nanliu orebody＇ s, the remaining oxides and trace elements are more than Nanliu samples＇ Beiyi orebody＇s diopside-tremolite rocks and high-grade Fe ores have weak Eu negative anomaly, and Nanliu orebody＇ s iopside-tremolite rocks and high-grade Fe ores have Eu positive anomaly, and all samples have the characteristic of weak Ce negative anomaly and LREE depleted and HREE enriched relatively. It reflected that metallogenic environments or late hydrothermal fluid affected of two ore bodies are different. |
