摘　　要：河北省非金属矿产资源丰富,但缺乏针对全省非金属成矿作用的综合研究。总结了河北省非金属矿产资源现状和产出特征,系统梳理了新太古代—古元古代、中元古代—中三叠世、晚三叠世—古新世及始新世—第四纪4个时段与非金属成矿有关的构造背景和成矿作用,应用矿床成矿系列理论将河北省重要非金属矿产厘定出6个矿床成矿系列组,9个成矿(亚)系列。研究表明:河北省非金属矿产主要有古元古代、中元古代、早古生代—晚古生代、燕山期及古近纪5个爆发性成矿期,主要矿床类型为变质型、沉积型、陆相火山岩型。根据不同时段、不同构造单元各具特色的成矿属性,指出了不同矿床类型和矿种的找矿有利地段,如:陆块隆起区是寻找变质型矿产(如石墨、碎云母等)的有利地段;坳陷区是寻找沉积型矿产(如石灰岩、海泡石黏土、岩盐等)的有利地段。研究成果可助力河北省“新一轮找矿突破战略行动”,为今后地质找矿工作部署提供参考。Nonmetallic mineral resources are abundant in Hebei Province,but comprehensive research on nonmetallic mineralization in Hebei Province is deficient.In this paper,the authors summarized the situation and distribution characteristics of nonmetallic deposits in Hebei province,and systematically carded the tectonic background and metallogenesis related with nonmetallic mineralization in the four periods of Neoarchean-Paleoproterozoic Middle Proterozoic-Middle Triassic,Late Triassic-Paleocene,and Eocene-Quaternary.According to the metallogenic series theory,the important nonmetallic minerals were divided into 6 groups and 9 subgroups.The results show that there are 5 explosive metallogenic periods of nonmetallic minerals in Hebei Province,including Paleoproterozoic,Middle Proterozoic,Early and Late Paleozoic,Yanshanian and Paleogene,and the main deposit types are metamorphic type,sedimentary type and continental volcanic rock type.Based on the characteristic metallogenic attributes of different tectonic units in different time periods,the favorable prospecting areas of different deposit types and ore species were pointed out.The uplift area of the land block is a favorable area for finding metamorphic minerals,such as graphite and broken mica.The depression area is a favorable area for finding sedimentary minerals such as limestone,sepiolite clay,and rock salt.The purpose of this paper is to promote the strategy of A new round of prospecting breakthrough in Hebei Province,and provide some references for the deployment of geological prospecting work in the future.
