摘要:
江西西北部地区锂及稀有金属矿成矿地质条件优越,有闻名全国的雅山、同安等超大型稀有金属矿床及众多含锂瓷石矿床,矿床类型较多,资源潜力巨大。本文通过论述江西西北部地区锂及稀有金属矿床的成矿地质背景、主要锂矿床地质特征、锂矿床成因及成矿模式,总结该区锂及稀有金属矿床成矿规律、找矿标志和找矿潜力。结果表明:江西西北部地区锂及稀有金属矿属岩浆晚期残留岩浆气液生成,其找矿标志为多期次侵入浅色细粒花岗岩且花岗岩中F、Nb、Ta、Li、Rb、Cs含量高,隆起区断裂构造发育和相互交切部位,钠长石化、锂云母化、黄玉化等蚀变现象,Li、Nb、Sn、W等亲氧元素异常,Nb、Ta、Sn、W等重矿物异常等。通过对甘坊及雅山地区锂资源量进行半定量估算,根据雅山地区物化探异常走势图及成矿岩体标志等,认为路口—雅山、高岭—江家岭为两个重要找矿潜力区。
Abstract:
Northwestern Jiangxi is endowed with the ore-forming geological conditions for lithium and rare metals. It hosts well-known superlarge rare metal ore deposits(Yashan and Tong’anore deposits)and many lithium-bearing porcelain ore deposits and various deposit types, suggesting its huge potential of mineral resources. This paper describes the metallogenic geological background and the geological features of the main lithium ore deposits, with an emphasis on the ore genesis and metallogenic mode of of lithium ore deposits, and also summarizes the metallogenic regularity and prospecting criteria of lithium and rare metals deposits. The results show that the ore deposits of lithium and rare metals in the northwestern part of Jiangxi resulted from the activity of late residual magmatic gas and liquid. The prospecting criteria of lithium and rare metals include multi-stage intrusive light-colored fine-grained granite and high contents of F, Nb, Ta, Li, Rb and Cs. Faulting structures in the uplift area are well developed. Alteration includes albitization, lepidolitization, and topaz lithification, accompanied by anomaly of elements, such as oxyphile elements(Li, Nb, Sn and W)and heavy minerals(Nb, Ta,Sn and W). Based on the semi-quantitative estimation for lithium resources in the Ganfang and Yashan regions, along with geophysical and geochemical anomalous trend map and ore-forming signatures in the Yashan area, it can be concluded thatthe Lukou-Yashan and Gaoling-jiangjialing areas are two important areas withprospecting potential.
