矿床位于幕阜山花岗岩体南西缘与板溪群片岩接触带伟晶岩密集区。矿化伟晶岩墙大多受 NEE向纵向节理控制 ,并位于幕阜山岩体的边缘。矿区内已发现 7个矿体 ,它们通常呈脉状 ,延深约 1 0 0 m。矿石为花岗伟晶结构和条带状构造。含铌、钽的矿物主要包括铌铁矿、钽铁矿和绿柱石 ,它们主要分布于分异晚期的块体带中。地球化学和同位素研究表明 ,该矿床为一岩浆 -交代伟晶岩型矿床 ,成因上与幕阜山花岗岩体有关。
The deposit is located in the pegmatite-intensive area at the contact zone between the southwestern margin of the Mufushan granite body and the schist of the Banxi group. The mineralized pegmatite wall is mostly controlled by the longitudinal joints of the NEE and is located at the edge of the Mufushan rock mass. Seven ore bodies have been found in the mining area. They are usually vein-shaped with a depth of about 100 m. The ore is of granitic pegmatism and banded structure. The minerals containing niobium and tantalum mainly include niobite, tantalite and beryl, which are mainly distributed in the late-stage block belt. Geochemical and isotopic studies show that the deposit is a magmatic-metasomatic pegmatite deposit and is genetically related to the Mufushan granite.
