摘要
矿床品位-吨位模型是矿产资源潜力评价的重要组成部分。以1999年全国矿产储量数据库的资料为依据,在对全国285个硫矿床进行频率直方图、正态及对数正态统计检验的基础上,建立了不同类型硫矿床的品位-吨位模型。不同类型的模型分布特征表明,中国硫矿资源的找矿前景良好、潜力巨大,其中热液黄铁矿型硫矿床和黄铁矿沉积型硫矿床是今后主要的找矿类型和方向。
Grade-tonnage model is an important part of mineral resource potential evaluation. Based on the National Reserve Database of Mineral Resources in China （1999） and the statistical validation in terms of frequency histogram, normal distribution and lognormal distribution of 285 sulfur deposits all over the country, this paper established separate models for all different deposit types. The distribution characteristics of all types show that the sulfur resource prospecting potential in China has a preferable prospect, furthemore, hydrothermal-pyrite type and pyrite sedimentary type of sulfur deposit are main prospecting types and direction for the future.
