  1. Through the study of characteristic of macroelement, microelement, rare - earth element, oxyhydrogen isotope, sulfur isotope, lead isotope, fluid inclusion etc, a conclusion can be drawn that metallogenic substance comes from the upper mantle with mixing of some substance from the upper crust latter. it is likely to have the same source with the surrounding rock

    通過對礦床的常量元素、微量元素、稀土元素、流體包裹體特徵、氫氧同位素、硫同位素、鉛同位素等特徵的研究，認為成礦物質主要來源於上地幔，與周圍巖石存在著同源的可能性，後期有一定的上地殼物質混入，成礦作用有三期，分別與區內的花崗巖、二長花崗巖脈、雲煌巖脈有關。
  2. Substance of rock - forming and ore - forming in both jianchaling and jinchuan nickel deposit mainly derived from the upper mantle, but the former source is relatively depleted mantle. on the other hand, there exsisted the crustal contamination during the formation of the two mineral deposits, the later contaminated poorly and gave priority to deep contamination. ( 5 ) by the comparative study of jianchaling with jinchuan nickel sulflde deposit, it is pointed that small basic - ultralbasic complexes which dis

    （ 5 ）通過對煎茶嶺和金川鎳礦床的比較研究，結合對國內外有關巖漿鎳礦床的比較分析，根據我國的地質特點，提出沿較老地塊邊緣分佈的特別是沿華北地塊北緣分佈的基性?超基性小雜巖體，是找尋大而富的硫化鎳礦床之有利找礦方向；而對較老地塊內部的鎂鐵質侵入體，亦應給予高度注意。
