通过野外调查、岩相学、矿物化学和岩石地球化学研究，认为泥盆纪以酸性海相火山岩为主的含矿岩系下部富钠和上部富钾是交代变质作用的产物；通过碱交代作用的热力学计算，初步认为：在对流循环成矿模式中，下降的海水被加热时由于温度的升高发生钠交代作用，成矿流体在运移和喷出过程中由于温度的降低而发生钾交代作用。
Through the field investigation, petrography, mineral chemistry and geochemical research, it is concluded that the lower part of the Devonian and the upper part of the ore-bearing rocks that contain acidic marine volcanic rocks are the products of metasomatic metamorphism; Thermodynamic calculation, it is preliminarily believed that in the convection-cycle mineralization mode, sodium desorption takes place due to the increase of temperature when the descending seawater is heated, and the replacement of potassium occurs due to the decrease of temperature during the migration and discharge of ore-forming fluids effect.
