The characteristics of elements shows that magma of fine dioritequartz diorites derived from the enriched mantle or lower crust undergone ocean crust subducting and dehydrating, and was formed and emplaced in the process of crust growth. The magma of dioritic porphyritedacitic porphyries emplaced relatively late, it might derive from upper crust or undergo intensive contamination of crustal materials, and was formed in the proces of crust thining. These characteristics suggest that the geodynamics background of the Jinchanggouliang gold deposit formation is the transition process from compression to extension.

元素地球化学特征显示：细晶闪长岩-石英闪长岩的岩浆源于富集地幔或洋壳俯冲脱水交代的下地壳，地壳增厚过程产生并就位；闪长玢岩-英安斑岩类的岩浆就位相对晚，来源具有上地壳性质或被地壳物质强烈混染，地壳减薄过程形成；这种特征暗示金厂沟梁金矿形成的地球动力学背景是在地壳挤压增厚转化为伸展减薄过程。
