摘要
娘娘顶铍矿床位于桐柏—大别成矿带之鸡公山岩体南缘,矿区内新元古代至中生代中酸性岩体(脉)发育,岩性以二长片麻岩、黑云母花岗岩和花岗岩等为主。矿体形态复杂,总体以分叉状向北西向和北东东向两侧展布;矿体在地表呈透镜状,围岩为娘娘顶岩体黑云母二长花岗岩和黄麦岭岩组变质岩地层。在细致的野外调查基础上,对娘娘顶铍矿床开展了系统的矿床地质特征、控矿因素、找矿标志、矿物学和矿相学研究,结合前人研究成果,探讨矿床成因,构建矿床成矿模式,总结成矿规律,梳理找矿方向,为开展下一步找矿勘查提供理论支撑。
Niangniangding Beryllium Deposit is located on the southern margin of Jigongshan rock mass in Tongbai-Dabie metallogenic belt.The mining area is characterized by the development of Neoproterozoic to Mesozoic intermediate-acid rock mass(dykes),predominantly composed of monzonitic gneiss,biotite granite,and granite.The ore bodies have complex morphologies,generally branching out towards the NW and NEE.On the surface,the ore bodies appear as lenticular shapes,with surrounding rocks comprising biotite monzonitic granite of the Niangniangding rock mass and metamorphic rock strata of Huangmailing rock formation.Based on detailed field investigations,systematic studies on the geological characteristics,ore-controlling conditions,prospecting indicators,mineralogy,and minera-graghy of Niangniangding Beryllium Deposit were conducted.Integrating previous research results,the genesis of the deposit was explored,a metallogenic model was constructed,metallogenic regularities were summarized,and prospecting directions were clarified,providing theoretical support for future exploration.
