摘　　要：本文以《湖南省越城岭地区稀有稀散金属矿产调查评价》为依托,通过挖掘区内区域化探资料信息,详细分析了越城岭岩体的元素分布分配和富集规律等地球化学特征,论述了越城岭岩体稀有、钨锡等金属找矿潜力巨大,并运用类比法,对越城岭岩体两处重要铷异常区进行了资源潜力预测,预测估算两异常区可达工业品位的矿体Rb2O金属量均达大型以上(大于2 000t)。Based on the Program of the Investigation and Evaluation of Rare and Scattered Metals in Yuechengling Area of Hunan Province,the geochemical characteristics of the distribution and enrichment of the elements in the Yuechengling intrusive rock are analyzed by using regional geochemical data.This paper indicated that the resource potential of rare,the tungsten and tin metal in Yuechengling intrusive rock is huge.The resource potential of two important geochemical anomalies areas is predicted using the analogy method,which shows that the amount of Rb 2O metal of the two anomalous areas up to the industrial grade will be more than 2 000 tons.
