河北青龙西汉沟金矿矿床地质特征及找矿标志

The geological characteristics and prospecting signs of Xihangou gold deposit in Qinglong County,HeBei

西汉沟金矿床位于华北板块北缘之冀东金成矿带,区域成矿地质条件优越,本文研究成果认为:矿床受控于窑上~迎午山韧性剪切带派生的次级糜棱岩化带,具有较大的找矿空间;矿床发育硅化、黄铁矿化、毒砂化、绢云母化、碳酸盐化等蚀变,其中毒砂化、黄铁矿化和硅化与成矿关系更为密切,是重要的直接找矿标志;Au异常与As、Sb异常套合良好的部位,找矿潜力较大,是重要的间接找矿标志。

Xi-hangou gold deposit is located in the northern edge of the North China plate,the East Jincheng mineral belt,the regional mineralization geological conditions are superior,the results of this paper believe that:the deposit is controlled in theYaoshang–Ying-wushan toughness shear belt derived from the secondary osteo-prism belt,with a larger prospecting space;Yellow iron ore,toxic sanding,coinalysis,carbonate and other erosion,in which toxic sandification,yellow iron ore and siliconization and mineralization are more closely related,is an important direct finding mark;Au abnormal and As,Sb abnormal fit good parts,prospecting potential is large,is an important indirect mining signs.
