摘要
竹溪县蒋家堰铌钽矿为岩浆岩型,铌钽矿体受构造蚀变带控制。研究认为,矿床位于变辉绿岩体中,受构造蚀变带控制,矿体具有似层状、条带状特征;岩体含矿性及微量元素含量特征为铌、轻稀土元素富集;总结该矿床岩石地球化学异常特征及地球化学找矿标志,为该区找矿提供参考。
Niobium-tantalum ore in Jiangjiayan is magrnaticrock type, niobium-tantalum ore bodies controlled by tectonicalteration belt. Research shows that the deposit is located in the change of diabase, controlled by tectonic alteration belt.Ore body has bedded, banded characteristics. The content characteristics of ore bearing and trace elements in rock massare niobium and light rare earth elements. The paper summarizes geochemical anomalies of the deposit and geochemicalprospecting criteria, provides the reference for the the prospecting area.
