摘要
通过铀矿综合区调,在化尖地区发现伟晶状花岗岩脉群长约8—17km,宽约2—4km,特别在尖扎附近分布集中。主要矿石矿物为晶质铀矿、铀石,铀矿化主要富集在伟晶状花岗岩内黑云母集中区、伟晶状花岗岩脉与黑云母斜长片麻岩接触带处。
Through comprehensive regional prospecting reconnaissance for uranium, pegmatoid granite dyke swarms with the length of 8-17km and the width of 2-4km have been discovered in Hua-Jian area and they are particularly concentrated near Jianza area. Main ore minerals are uraninite and coffinite. Uranium mineralization is mainly present in the biotite-concentrated site within pegmatoid granite and at the contact between pegmatoid granite dykes and biotite plagiogneiss.
