摘　　要：西藏甲玛铜多金属矿床是在商业性勘查过程中,成矿系列理论指导实践取得的找矿成果,并已成为冈底斯成矿带内目前发现的为数不多的斑岩-矽卡岩-角岩型超大型矿床之一。文章以Micromine软件为操作平台,运用地质统计学方法,通过地质数据库建立→数据分析、特高品位处理→半变异函数分析→克立格品位插值→储量计算等步骤,对甲玛矽卡岩型矿体中共伴生元素的储量进行了较为准确的计算。地质统计学在矿产储量计算过程中经过严谨的统计分析、计算、检验步骤,较传统的储量计算方法表现出的优势日趋明显。The Jiama copper-poiymetallic deposit in Tibet is the result of commercial exploration and metallogenic theory direction. Now, it has been one of the few porphyry - skarn - hornfels type superlarge deposits in the Gangdese metallogenic belt. Based on the Micromine software, this article has calculated the reserves of symbiotic and associated elements of the deposit accurately using the geostatistics methods, by establishing the geological data- base, data analysis and dealing with the extreme high grade of every element, the semi-variogram analysis, grade interpolation to the geological blocks u- sing the Kriging and calculating every element＇ s reserves. Through the rigorous statistical analysis, calculation, test steps, geostatistics method is better than traditional methods in the calculation of minerals reserves.
