摘要
茅岭锂矿床位于江西九岭南缘,属江南东段成矿带九岭成矿亚带,是近年来九岭南缘宜丰地区蚀变花岗岩型锂矿取得重大找矿突破的成果之一,以ω(Li_(2)O)>0.2%圈定矿体获得氧化锂资源量达超大型。通过详细的野外地质调查,矿区勘查,厘定了矿区燕山期花岗岩的空间分布、期次、侵入关系等特征,明确了白云母花岗岩与锂矿的成矿专属性。根据茅岭锂矿床地质特征、矿石特征和锂元素赋存状态,认为九岭南缘茅岭蚀变花岗岩型锂矿为碱交代成因。研究成果将为该地区周边锂矿勘查和研究提供参考。
The Maoling lithium deposit is located on the southern edge of Jiuling in Jiangxi province,belonging to the Jiuling mineralization sub zone of the eastern section of the Jiangnan mineralization belt.It is one of the major breakthroughs in the exploration of altered granite type lithium deposits in the Yifeng area of the southern edge of Jiuling in recent years.The delineation of the ore body withω(Li_(2)O)>0.2%has yielded a super large amount of lithium oxide resources.Through detailed field geological investigation and mining area exploration,the spatial distribution,stages,and intrusion relationship of the Yanshanian granite in the mining area have been determined,and the association of muscovite granite with lithium deposits has been clarified.Based on the geological characteristics,ore characteristics,and lithium element occurrence status of the Maoling lithium deposit,it is believed that the Maoling altered granite type lithium deposit on the southern edge of Jiuling is of alkali metasomatic origin,providing a reference for the exploration and research of lithium deposits in the surrounding area.
