摘　　要：在阜平北辛庄圈定一处脉石英找矿靶区,分布在阜平隆起五台期韧性剪切带发育区内。本文依据找矿工作成果和搜集资料,分析认为该地区脉石英属于低温—中低温变质热液成因,规模较小,有两种产出形态,“脉状”和“透镜状”,前者规模相对较大。脉石英化学成分及含量基本符合高纯石英原料矿的要求。通过对脉石英地质特征进行总结和成因分析,旨在为河北省高纯石英原料找矿提供帮助和指导。A vein quartz prospecting target has been delineated in Beixinzhuang in Fuping,which is distributed in the Wutai stage ductile shear zone of Fuping uplift.Based on the prospecting results and collected data,it is considered that the quartz in Fuping vein belongs to the metamorphic hydrothermal origin of low temperature to middle temperature.The scale is small and there are two kinds of occurrence forms,"veined"and"lenticular".The chemical composition and content of vein quartz basically meet the requirements of high purity quartz ore.This paper summarizes the geological characteristics of vein quartz and analyzes its genesis in order to provide help and guidance for the prospecting of high purity quartz raw materials in Hebei province.
