摘要
Deep exploration was carried out in Jinchuan mine of Gansu Province by using magnetic method, controlled-source audio-magneto-telluric method, and P wave seismic tomography. The researches based on the above methods revealed the high resistivity and high velocity characteristics of the magma source to the depth of over 2 500 m, suggesting that the lava came to the shallow part and spread on both sides to form shallow nearly-horizontal lenticular branches. The fact provides geophysical evidence for the metallogenic model of the Jinchuan copper-nickel mine.
