Analysis reveals rich geological features and chemical properties in a new granite-type lithium mineralization area, suggesting implications for resource exploration.
赣西北狮子岭岩体为九岭地区新发现的花岗岩型锂矿化岩体。该岩体除发育锂云母、锂白云母等常见锂矿物外,还存在较为罕见的磷锂铝石。然而针对该岩体富f高p的岩体特征、岩石成因以及f和p对锂成矿过程的作用,尚未得到深入研究。本文以详细的野外工作为基础,运用光学显微镜、电子探针(epma)以及矿物参数自动定量分析仪(amics),对狮子岭岩体中的长石、锆石、磷酸盐矿物(磷灰石、磷锂铝石、磷铝锰矿)的产状、结构与化学成分展开深入研究。研究结果表明:从二云母花岗岩到锂(白)云母花岗岩,再到黄玉-锂云母花岗岩,岩石中长石与锆石的p₂o₅含量呈逐渐升高态势。磷锂铝石蚀变为磷灰石,细粒状锂云母在黄玉-锂云母花岗岩中结晶,在锂(白)
