摘要
近年来在对迎门岔地区的1∶20万水系沉积物异常进一步检查时,在早白垩世林子头组火山岩中,发现一条铌钽矿化体,其赋存层位、构造条件、地球化学特征等均表现出有利成矿的因素。通过对该矿化体在地层、构造、岩浆岩及物化探异常等方面特征的综合分析,对比邻区相似矿化体的地质特征,尝试寻找该矿化体的主要控矿因素、找矿标志,预测成矿类型,探索该区的进一步找矿方向。
In recent years, when further checking the 1∶200 000 river sediment anomaly in Yingmencha area, a niobium tantalum mineralized body was found in the volcanic rocks of Linzitou Formation in the Early Cretaceous. Its occurrence horizon, structural conditions, geochemical characteristics, etc. all show favorable factors for mineralization. Through comprehensive analysis of the characteristics of the mineralized body in terms of stratum, structure, magmatic rock, geophysical and geochemical anomalies, the geological features of similar mineralized body in the adjacent area were compared, try to find the main ore controlling factors and prospecting indicators of the mineralized body, predict the metallogenic type and explore the further prospecting direction in this area.
