摘 要:丰宁头道沟一带萤石矿赋存于下白垩统张家口组火山碎屑岩中,共发现2个矿体,呈脉状产出。矿石类型属石英萤石型,矿石结构为粒状结构,块状构造,少量皮壳状构造及条带状构造。属于岩浆期后中—低温热液充填型脉状矿床,为构造—岩浆活动的产物。The fluorite ore in the Fengning Tou daogou area was deposited in the volcanic clastic rocks of the Zhangjiakou formation of the lower Cretaceous system, and a total of 2 ore bodies were found, which were vein-like. The ore type belongs to the quartz fluorite type, and the ore structure is a granular structure, a block structure, a small amount of shell structure and a strip structure. It belongs to the medium-low temperature hydrothermal filled veined mineral deposits after the magmatic period, and is the product of tectonic-magmatic activity.
