从1988年到1994年,全国部分主要铅锌矿分布省(区)开展了铅锌矿资源总量预测工作。根据已完成铅锌矿资源总量预测工作的省(区)资料推算,全国铅锌矿资源总量为6.29亿吨。未查明资源量为4.57亿吨,尚有72%的资源尚待查明。根据中国大陆成矿体系研究,我国主要成矿区带的铅、锌资源总 From 1988 to 1994, some major lead-zinc ore provinces (regions) in the country carried out the prediction of the total amount of lead-zinc mine resources. According to the provincial (district) data of the total lead and zinc mine resources forecast, the total amount of lead and zinc mine resources in the country is 629 million tons. Not identified 457 million tons of resources, there are still 72% of the resources yet to be identified. According to the study of metallogenic system in China, the total lead and zinc resources in the main metallogenic belt in China
