摘要 河北省硫铁矿资源丰富,矿床类型多样。本文以Ⅳ级成矿亚带为基础,讨论了5个成矿亚带内硫铁矿资源分布特点及成矿作用,认为燕辽(坳陷、拉张)Cu-Mo-Pb-Zn-Ag-Au-Fe-Mn-煤成矿亚带(Ⅲ-57-(2))、太行FeMn-铝土矿—石膏—煤—煤层气成矿亚带(Ⅲ-61-(3))最具资源潜力;河北省硫铁矿矿床成因类型以化学沉积型、接触交代型最为重要;蓟县纪、燕山期为成矿高峰期,主要赋矿层位为蓟县群高于庄组、石炭—二叠系煤系地层。全面总结了河北省硫铁矿成矿规律,指出找矿有利地段和远景区,为河北省硫铁矿下一步勘查开发工作提供参考。 Hebei Province is rich in pyrite resources with various types.In this paper,the distribution characteristics and mineralization of pyrite resources in five metallogenic subzones are discussed based on IV grade metallogenic subzone.It is considered that Yanliao(depression,extension) Cu-Mo-Pb-Zn-Ag-Au-Fe-Mn-coal metallogenic subzone(Ⅲ-57-(2)) and Taihang Fe-Mn-bauxite-gypsum-coal-coalbed methane metallogenic subzone(Ⅲ-61-(3)) have the most resource potential.The research shows that the genetic types of pyrite deposits in Hebei Province are the most important ones:chemical depositional type and contact metasomatism type.It has two metallogenic peak periods of Jixian and Yanshan periods.The main ore-bearing strata are Gaoyuzhuang formation of Jixian group and Carboniferous-Permian coal measure strata.The study comprehensively summarizes the metallogenic law of pyrite in Hebei Province,points out favorable areas and prospective areas for prospecting,and provides a theoretical basis for guiding the next exploration and development of pyrite in Hebei Province.
