摘要
针对甘肃肃北鱼脊山一带发育区域变质矿床的基础地质条件,文章对鱼脊山蓝晶石矿的地质特征进行了研究,认为:鱼脊山蓝晶石矿赋存于敦煌岩群二岩组片岩+大理岩段及片岩段中,与区域变质作用密切相关,且该层位延伸稳定,找矿潜力巨大;矿体Ky2、Ky3 平均厚度大,连续性好,延伸稳定,在延伸方向具有良好的找矿前景.
Abstract
In view of the basic geological conditions of the regional metamorphic deposits in the development area of Yuji Mountain in Subei County,this paper studied the geological features of the kyanite deposit in Yuji Mountain,and believed that the kyanite ore in Yuji Mountain occurred in the schist+marble member and schist member of the Dunhuang rock group,which is closely related to regional metamorphism,and the horizon extension is stable and has great prospecting potential.At the same time,it was proposed that Ky2 and Ky3 in the mining area has large average thickness,with good continuity,stable extension,and good prospecting potential in the extension direction.
