摘　　要：围场密林沟伊利石矿赋存于中生界上侏罗统张家口组火山碎屑岩石中,共发现2个矿体,呈层状、似层状产出,层位稳定,矿体规模较大。矿石类型主要为石英伊利石型,矿石结构致密,块状构造,也见角砾状构造。由前期火山岩经过后期热液交代形成,属热液蚀变型伊利石矿床。The milingou illite deposit in Weichang occurs in Weichang milingou illite deposit occurs in the pyroclastic rocks of Zhangjiakou formation of Upper Jurassic in Mesozoic. A total of two ore bodies are found, which are layered and quasi layered,with stable horizon and large scale. The ore type is mainly quartz illite type, with dense ore structure, massive structure and breccia structure. It is a hydrothermal altered illite deposit formed by early volcanic rocks through later hydrothermal metasomatism.
