| 中文摘要: |
| 根据《锂(Li)地球化学图》(贵州省地球化学图集，冯济舟等，2008)显示，晴隆县城北侧一带、普安青山一带、兴义万屯一带、安龙县城北侧一带均有较好的锂(Li)异常显示。经研究选取了普安青山一带开展了少量地质工作，发现锂(Li)异常层位主要为第四系(Q)残坡积松散黏土层，含锂(Li)黏土基底为强风化白云岩，下部为杂色黏土夹少量强风化白云岩碎块，中下部为土黄色、浅紫色黏土，中部及上部为褐红色黏土。经地表及浅井工程采集样品检测，基底白云岩含锂(Li)144 ug/g，黏土中锂(Li)含量最高达303 ug/g，平均含量200 ug/g，超过锂(Li)元素在地壳中克拉克值的10倍。经初步分析，本次研究工作显示了黔西南锂(Li)异常区具备一定的研究价值和找矿潜力。 |

| According to the Li Geochemical Map(Guizhou Geochemical Atlas，Feng Jizhou，etc，2008)，it shows that there are good Li anomalies in the north of Qinglong County，Pu’an Qingshan，Xingyi Wantun and Anlong CountyAfter conducting a small amount of geological work in the Qingshan area of Pu’an，it was found that the lithium(Li)anomaly layer is mainly the Quaternary(Q)residual slope loose clay layerThe lithium(Li)clay base is strongly weathered dolomite，the lower part is variegated clay with a small amount of strongly weathered dolomite fragments，the middle and lower parts are yellow and light purple clay，and the middle and upper parts are brownish red clayAfter surface and shallow well engineering sample collection and testing，the basement dolomite contains 144 ug/g of lithium(Li)，and the lithium(Li)content in the clay is as high as 471 ug/g，with an average content of 200 ug/g，exceeding 10 times the Clark value of lithium(Li)element in the crustAfter preliminary analysis，this research work shows that the lithium(Li)anomaly area in southwestern Guizhou has certain research value and prospecting potential |
