| 摘 要： | 经对1：20万区域化探异常AS59进行1：1万土壤加密测量，圈定出3条北西走向的Li异常带，并进一步划分为7处子异常.异常强度较强，峰值最高1651.1×10-6，规模较大，Li异常浓集中心明显，均具有内、中、外带分布特征.表层与深部样品中Li含量比较均匀，各类方法采集的样品中Li含量基本一致.引起Li异常的是3条赋存在晚侏罗世钠长石化流纹斑岩内的锂稀有金属矿化蚀变带，地表刻槽取样分析Li 0.08×10-2~0.136×10-2.结合深部地球化学研究及地质背景，认为该区锂矿找矿有望取得重大突破.

| Abstract: | Based on 1：10 000 densified soil survey for 1：200 000 regional geochemical exploration, three NW-trending Li anomalous zones are delineated within the AS59 geochemical anomaly area. They are further divided into seven sub- anomalies, which are relatively strong, with peak value up to 1651.1 × 104, in large sizes and with obvious Li concentration centers, showing the inner-middle-outside zonation. The Li contents in surface and deep layer samples are uniform. There is also a consistence of Li contents in samples collected with different methods. The Li anomaly is caused by three rare metal mineralized alteration belts that are developed in the Late Jurassic albitized rhyolitic porphyry. The channel sampling analysis shows the Li contents of 0.08 ×10-2 - 0.136 ×10-2. With integration of deep geochemical study and geological background, the lithium prospecting in this area should contribute to a significant breakthrough. |
