摘要
尼日利亚矿产资源丰富,以往勘探以石油、天然气、金、锡为主,近年来锂矿开发成为热点。本文在纳萨拉瓦州某锂矿区地质调查的基础上,开展物探测量方法有效性试验。选择激电中梯短导线测量和音频大地电磁测深(ATM),在已知含锂伟晶岩矿体开展剖面试验测量。试验测量结果表明,激电中梯短导线测量和音频大地电磁测深方法对含锂伟晶岩矿体具有较好的有效性;针对伟晶岩型锂矿床,物探成果结合区内地质成果资料可以有效优选找矿靶区。
Nigeria is rich in mineral resources.In the past mineral exploration is mainly focused on oil and gas,Au and Tin and now exploitation of Li has been the hot point.Based on geological survey in a Li deposit in Nasarawa area IP ladder survey and audio magnetotelluric sounding survey are used to conduct profile test and prove the validity on the known ore body.Result of the test shows that the two geophysical techniques are effective to locate Li-bearing pegmatite.Combined with geological data the geophysical data can be used to optimally lineate target in the deposit.
