摘　　要：矿床品位-吨位模型是表征某一类矿床品位和吨位变化范围及其频率分布的定量化模型,也是矿产资源潜力评价的重要组成部分。本文选取黔西北猪拱塘超大型铅锌矿床为研究对象,依据其综合勘查资料,利用SPSS及Excel软件对黔西北猪拱塘铅锌矿床153个矿体块段(最小研究单元)的品位、吨位数据进行频率分布处理及分析,然后进行P-P图正态检验,构建矿床的品位模型、吨位模型以及品位-吨位联合模型。研究结果表明黔西北猪拱塘铅锌矿床品位模型服从正态分布,吨位模型服从对数正态分布,并通过模型总结出矿床铅、锌品位-吨位分布特征,为矿床今后的找矿预测工作提供指导。The grade-tonnage model of ore deposit is a quantitative model describing the variation range and frequency distribution of grade and tonnage of a certain type of ore deposit,which is an important part of mineral resource potential evaluation.This article selects Zhugongtang super-large lead-zinc deposit of the northwestern Guizhou as the research object,on the basis of the comprehensive exploration data,using SPSS and Excel software to process and analyze the frequency distribution of grade-tonnage data of 153 ore block section(minimum research unit)of Zhugongtang lead-zinc deposit in the northwest Guizhou and,then A P-P plot normality test is carried out,construct the grade model and tonnage model and grade-tonnage combined model.The results show that the grade model of Zhugongtang lead-zinc deposit in northwest Guizhou follows normal distribution,and the tonnage model follows lognormal distribution.The distribution characteristics of lead-zinc grade and tonnage in the deposit are summarized by the model,which can provide guidance for future prospecting and prediction work of the deposit.
