广东梅子窝钨矿床59#脉构造叠加晕研究

摘要

应用构造叠加晕理论,研究广东梅子窝石英脉型黑钨矿床59#矿脉的微量元素地球化学特征,确定成矿元素在矿区的背景值以及矿体不同部位的含量,得出单一成矿作用所形成的原生晕轴向分带序列为Sb、As(前缘晕)→W、Bi、Pb、Mn、Ag、Zn、Cu(近矿晕)→Be、Sn(尾晕),矿脉(由深到浅)原生晕轴向分带序列为Cu→Sn→Co→Be→Ag→As→Zn→Cd→Sb→Pb→Bi→Mo→Fe→Mn→W,建立了梅子窝钨矿床59#矿脉的构造叠加晕模式,并用此模型确定了盲矿预测的构造叠加晕标志,为深部矿脉以及矿区的深部找矿提供理论依据.%The application of the theory of structural superimposed halo, study on trace element geochemical characteristics of 59#vein of the quartz vein-type tungsten deposit in Meiziwo Guangdong.It is concluded that the axial zoning sequence of primary halo formed by single mineralization is Sb、As(front halo)→W、Bi、Pb、Mn、Ag、Zn、Cu(near ore halo)→Be、Sn(rear halo),the vein (from deep to shallow)primary halo zoning sequence is Cu→Sn→Co→Be→Ag→As→Zn→Cd→Sb→Pb→Bi→Mo→Fe→Mn→W,established the model of structural superimposed halo 59#vein of Meiziwo tungsten deposit,and use this model to determine the structural superimposed halo of blind ore prediction marks,provide a theoretical basis for deep vein and deep prospecting.
