Abstract:
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.
