| 中文摘要:硼矿是中国重要的紧缺矿产,长期依赖进口,找寻新的硼矿资源迫在眉睫。笔者在湘南地区芙蓉锡矿床新发现了矽卡岩型硼矿化,硼矿物包括硼镁铁矿、遂安石和氟硼镁石,1件典型样品的X射线粉晶衍射分析结果表明硼矿物总含量达到47.4%,换算成w(B)(以B2O3计)约为9.5%,高于5%的硼矿最低工业品位。该发现预示着湘南地区,乃至华南与高分异花岗岩有关的钨锡多金属矿集区有良好的硼成矿潜力,在今后的找矿过程中,需加强与钨锡多金属共伴生的硼矿化评价工作。 |

| Abstract:Boron ore is important but in short supply in China, and thus is of significance to find new boron resources.This paper discovers skarn boron mineralization in the Furong tin deposit of southern Hunan area, with ore minerals including ludwigite, suanite and fluoborite. A typical sample conducted by X-ray powder diffraction analysis shows that the boron mineral reached 47.4% in volume, with B2O3 content about 9.5% when converted into mass fraction, which is higher than the industrial ore grade. This discovery indicates that there is a good potential for boron mineralization in tungsten-tin polymetallic skarn deposits associated with highly fractioned granite in southern Hunan area and extends to south China. The evaluation of boron mineralization associated with highly fractioned granite is necessary for future prospecting processes. |
