中文摘要：

会泽铅锌矿床位于扬子地块西南缘的川滇黔铅锌成矿域中部,由矿山厂和麒麟厂2个矿段组成,具有规模大（Pb＋Zn金属量超过500万t）、品位高（Pb＋Zn质量分数超过25%）等特征。矿山厂矿段主要由1号矿体构成,矿石类型以氧化矿为主,已探明的Pb＋Zn金属量超过100万t。变异函数模拟是反映区域化变量空间变化规律的有效手段之一。通过对矿山厂矿段1号矿体Pb、Zn元素的变异函数模拟,发现二者在走向、倾向和垂向上具有不同的基台值和变程,且数据规律显示矿体具有层控特征,这与地质特征相吻合;另外模拟还显示二者在倾向上具有较好的连续性。通过变程值的计算,当勘探网度设计为65m×145m时,即可达到较好的储量控制。

英文摘要：

Huize lead-zinc deposit locates in Sichuan Yunnan and Guizhou lead-zinc metallogenic domain of SW of Yangtze platform, and it consists of Kuangshanchang and Qilinchang, and it also has the character- istics of large scale（Pb＋Zn metal quantity more than 5 million tons） and high grade（Pb＋Zn content is more than 25%）. The No. 1 ore body is the main ore body in Kuangshanchang where the ore type is mainly oxidized ore, and the proven Pb＋Zn metal quantity has been more than 1 million tons. Variation function simulation is an effective means of reflecting the regionalized variable space change regular pattern. The authors, through variation function simulation of Pb-Zn elements in No. 1 ore body, found that both ele- ments have different partial sill and range in strike, tendency and vertical, and data regular shows that ore body has characteristics of stratabound, which is conformity with the geological characteristics. Simulation also shows that both on the tendency have good continuity. Through the calculation of variation value, re- serves could achieve better control when the exploration network design for 65 m×145 m.
