摘要
张三营铌铁矿位于隆化县通事营子碱长花岗杂岩体内部,区内构造发育,岩浆活动频繁,成分多样,持续时间长,丰富的构造活动及多期次的热液活动为区内稀有元素的富集提供非常有利的条件。通过深入研究区内铌铁矿成矿地质条件、矿体地质特征,总结了区内铌铁矿的找矿标志及成因机制,为区内下一步勘查工作的部署提供重要的参考和借鉴。
Zhangsanying niobium-iron mine is located in the alkali feldspar complex granite of Tongshiyingzi,Longhua county,where the structure is developed,the magmatic activity is frequent,the composition is diverse,the lasting time is long,the abundant tectonic activity and the multi-stage hydrothermal activity provide very favorable conditions for the enrichment of rare elements in the area.Based on the in-depth study of the ore-forming geological conditions and ore body geological characteristics of niobium-iron mine in the area,this paper summarized the ore prospecting indicators and genetic mechanism of niobium-iron mine,which can provide important reference for the next exploration work.
