摘要: 通过对内蒙古自治区赵井沟铌钽多金属矿床地质特征的分析,认为燕山期酸性岩体即为矿体,矿体受地层、构造、岩浆岩共同控制,为中低温岩浆热液脉型铌钽多金属矿,钠长石化和天河石化为本区铌钽矿床的直接找矿标志。

Abstract: Through the analysis on the geological feature of Zhaojinggou polymetallic Nb-Ta deposit in Inner Mongolia,it suggests that the acidic rock of Yanshannian is the prospected ore body,which is jointly controlled by stratus,structures and igneous rocks.It belongs to a low-and-medium temperature magmatic hydrothermal vein-type type Nb-Ta polymetallic ore deposit.Albitization and amazonitization are the direct prospecting criteria for Nb-Ta polymetallic deposit in this area.
