摘要
文章通过对辽宁省萤石矿的系统梳理与研究,从省级、矿集区及典型矿床三个尺度总结了萤石矿特征.结果表明全省萤石矿产地23处,主要分布于盖州瓦房峪-岫岩汪顺沟、义县三宝屯-阜新少冷、凌源太平沟-北票前梅林皋三个矿集区内,矿床成因类型单一,全部为中低温热液充填(交代)型,成矿时代主要为印支期和燕山期.以Ⅳ级成矿区带为界,综合考虑地质构造环境、构造演化特征、萤石矿成矿地质条件、成矿时代、成矿作用及矿产地分布等因素,划分了辽宁省萤石矿3个成矿系列、4个成矿亚系列,建立了萤石矿成矿谱系.
Abstract
This paper systematically studies fluorite deposits in Liaoning Province,and summarizes the char-acteristics of fluorite deposits from three scales of the whole province,ore concentration areas and typical de-posits.The study result shows that there are 23 fluorite deposits in the province,which are mainly distribu-ted in the three ore concentration areas of Wafangyu in Gaizhou to Wangshungou in Xiuyan,Sanbaotun in Yixian to Shaoleng in Fuxin,and Taipinggou in Lingyuan to Qianmeilingao in Beipiao.The genetic type of fluorite deposits is single,all of them are middle-low temperature hydrothermal filling(metasomatic)type.The metallogenic ages are mainly Indosinian and Yanshanian period.This paper divides three metallogenic series and four subseries bounded by grade Ⅳ metallogenic zone,and metallogenic lineage is established for the consideration of the factors of geological tectonic environment,structural evolution characteristics,met-allogenic geological condition,metallogenic age,mineralization and mineral occurrence distribution.
