摘要
本文利用海南岛东部浅海海域的最新资料,对2018年在该海域采集的78个站位的表层沉积物样品进行了化验分析,计算得出了锆英石、金红石、钛铁矿和白钛石4种锆钛砂矿有用矿物的折算矿物品位,并分析了这4种矿物的分布规律,在此基础上对锆英石进行了异常区划分。结果表明,研究区内仅有锆英石能达到工业指标的边界品位,位于研究区的西部和北部的锆英石Ⅰ-2级异常区和Ⅰ-1级异常区是开展下一步找矿工作的重点区域。
Using the latest information in the shallow waters east of Hainan Island,analysis the surface sediment samples collected from 78 stations in the sea area in 2018,and calculate the converted mineral content of four useful minerals of zirconite,rutile,ilmenite and titanomorphite,analysis the distribution regularity of these four minerals,on this basis,the anomalous area of zirconite is divided.The results show that only the zirconite can reach the cut-off grade of industrial index in the study area,and the zirconiteⅠ-2 andⅠ-1 anomaly areas where located to the west and north of the study area are key areas for further exploration.
