摘　　要：本文从地层、岩性、变质相、化学成分等方面对河北省灵寿-行唐一带碎云母矿床地质特征进行总结,并建立了沉积变质型碎云母矿的成矿模式。研究表明区内的上太古界湾子岩群陆源碎屑-碳酸盐岩夹基性火山岩沉积建造为碎云母矿的矿源层,沉积变质型碎云母矿床的形成经历了含矿建造的沉积、构造运动褶皱回返、区域变质作用等一系列地质过程。在此基础之上结合前人的研究成果,采用综合信息单元法圈定灵寿-行唐一带的新太古界湾子组是寻找碎云母矿床的有利层位。The strata, lithology, metamorphic facies and the chemical composition characteristics of broken mica deposits in Lingshou-Xingtang area, Hebei province are summarized, and the metallogenetic model of sedimentary metamorphic type broken mica deposit is established. The research shows that the ore source layers are the carbonate-clastic rocks in the area of volcanic-sedimentary formation of the Archean Wanzi Group for the broken mica deposits. Sedimentary-metamorphic type broken mica deposits are formed through a deposition, tectonic movement, regional fold return ore bearing formation of metamorphism and a series of geological process. Based on the previous research results, the prospecting areas for broken mica deposits in Lingshou-Xingtang areas are delineated by comprehensive-information-unit method.
