摘要
为了预测江苏省铅锌矿的资源潜力,首先分析了省内铅锌矿的资源现状,并按照矿床模型综合地质信息矿产预测方法,在中、大比例尺勘探数据的基础上,根据不同矿床类型建立了3个矿床综合评价模型,划分了4个铅锌矿预测工作区;然后在此基础上圈定预测单元,优选出29个最小预测区;再使用地质参数体积法估算了全省铅锌矿潜在资源量,预测1 000m以浅铅潜在资源量为96.83万t,锌潜在资源量为162.95万t;并进一步对铅锌矿的成矿条件及资源潜力进行分析研究,提出宁镇西段的4个最小预测区具有很大的找矿前景。
In order to evaluate the resource potential of lead-zinc deposits in Jiangsu Province,the authors firstly analyze the lead-zinc resources situation,then based on the exploration data at moderate or large scales,and by the method of integrated geo-information modeling,three comprehensive deposit evaluation models are established for different type of deposit and four evaluation working areas are divided in the province.Following above works,the evaluation unit division of the geological unit method are determined,and the 29 smallest evaluation areas are determined by eigen-analysis method.The potential resources of lead-zinc deposits for above 1 000 meters deep in Jiangsu Province are estimated at 968 300 tons for lead and 1 629 500 tons for zinc respectively.Four potencial areas of lead-zinc deposits west of Nanjing-Zhenjiang area are suggested based on metallogenic condition and the resource potential studies.The present study is benefical to lead-zinc deposit exploration in the province.
