摘要
通过对浙江省主要矿产的矿床数量、规模、矿产组合时间演化以及成矿分带性、丛聚性等特征的分析与归纳,概要总结了浙江省矿产资源的时空分布规律。通过系统收集和整理浙江省同位素成矿年龄资料,建立起全省成矿年代学谱系,并结合大地构造演化,将浙江省的成矿活动划分了5个时段。通过矿床数量、矿床规模以及矿产组合对比分析各时段的成矿信息和演化特征,构建了成矿时间演化图。依据浙江省矿产资源空间分布特征,将浙江省划分了4个Ⅲ级成矿带和7个Ⅳ级成矿亚带,从成矿密度和成矿强度的角度探讨各Ⅳ级成矿亚带矿床的分布规律。其中成矿密度划分了1个高密度区、4个中密度区和2个低密度区,综合矿产成矿强度划分了3个强成矿强度区、1个中成矿强度区和3个弱成矿强度区,以此为找矿方向和规划部署提供新思路。
Based on the synthesisof quantity,scale,mineral assemblage evolution,mineralization zonation,and the clusters of major mineral deposit data in Zhejiang Province,a summary of the spatiotemporal distribution of mineral resources was prepared.Systematic compilation and organization of the isotope metallogenic age data has also enabled establishment of the mineralization chronology pedigree in Zhejiang Province.Subsequently,by integrating this data with the tectonic evolutionary history,the metallogenic activities were divided into 5 periods.The metallogenic information and evolution characteristics of each period were analyzed on the basis of number and scale of mineral deposits and intercomparison of mineral assemblages to construct a metallogenic evolution diagram.Based on the spatial distribution characteristics of mineral resources,the Zhejiang Province was divided into 4Ⅲgrade metallogenic belts and 7Ⅳgrade metallogenic sub-belts.From the metallogenic density and intensity perspective,spatial distribution regularities ofⅣgrade metallogenic sub-belt are discussed.Metallogenic density was divided into 1 high density zone,4 medium density zones,and 2 low density zones.The comprehensive metallogenic intensity was divided into 3 strong metallogenic intensity zones,1 medium metallogenic intensity zone and 3 low metallogenic intensity zones.This overview provides new perspectives for future planning and prospecting.
