中文摘要:21世纪,随着对锂资源需求的不断增长,找锂矿成为提高锂矿资源保障能力的关键一环。作为锂矿家族中的重要一员,伟晶岩型锂矿床的找矿取得了重要突破,同时在预测理论和找矿技术方面也取得了重要进展。文章主要从6个方面的进展结合实例进行系统总结,以期有助于伟晶岩型锂矿找矿的新突破,包括:①地质找矿方向及找矿方法;②化探(含重砂)有效指示元素(重砂矿物)以及隐伏矿床化探找矿方法;③使用合适的遥感资料识别伟晶岩并判断其含矿性;④物探在推断与成矿有关的花岗岩和片(麻)岩穹隆构造以及在刻画伟晶岩岩脉地下空间展布中的作用;⑤各类综合找矿预测模型(或方法组合)的应用及效果;⑥潜在资源量估算的主要方法和与查明资源储量/资源量的区别等。
Abstract:The demand for lithium has skyrocketed in recent years. To address that demand, the discovery of new lithium deposits is crucial. Many granitic pegmatite-type lithium deposits have been discovered in the past several years, at the same time, many advances in prospecting prediction theories and technologies have been obtained. The main advances include:① geological prospecting directions and methods for granitic pegmatite-type lithium deposits; ② effective elements and natural heavy placer minerals indicating for granitic pegmatite-type lithium deposits, and geochemical exploration methods for buried granitic pegmatite-type lithium deposits; ③ how to use suitable remote sensing data to identify Li-bearing pegmatite; ④ roles of geophysical exploration for inferring the buried granites and gneiss domes associated with granitic pegmatite-type lithium deposits, and for describing space distribution of buried Li-bearing pegmatite veins; ⑤ application of all kinds of integrated prospec-ting models for Li-bearing granitic pegmatite; ⑥ the major estimation methods of potential resources and the distinctions between potential resources and the identified resource/reserves. Those advances will help to find new pegmatite-type lithium deposits.
