| 摘 要： | 为解决制约找矿突破的关键问题，运用勘查区找矿预测理论，通过开展构造-蚀变专项填图、典型矿床解剖等工作，重点研究了小秦岭金矿田石英脉型金矿床的成矿地质体、成矿构造和成矿结构面、成矿作用的特征标志；在综合分析研究的基础上初步构建了"三位一体"找矿预测模型；并结合岩石地球化学测量成果，圈定了13处找矿靶区，其中两处找矿靶区经工程验证见到工业矿体，初步证明陕西小秦岭金矿田石英脉型金矿床"三位一体"勘查区找矿预测地质模型预测效果良好，在矿田新一轮"攻深找盲"工作中具有现实的指导意义。

| Abstract: | To solve the key problems to prospecting breakthrough, on the basis of the theory of prospecting prediction in exploration area, by conducting works such as structural-alteration special mapping, typical deposits analysis, the ore-forming geological bodies, the metallogenic structures, the metallogenic structural surface and the characteristics of mineralization of quartz vein type gold deposits in the Xiaoqinling gold fields are studied. On the basis of comprehensive analysis and research, the "trinity" prospecting prediction model is constructed.In combination with rock geochemical survey results, 13 prospecting target areas are delineated, including two which reveal industrial orebodies verified by engineering preliminary evidence, identifying that the "trinity" prospecting prediction model has preferable performance in quartz vein type gold deposits in the Xiaoqinling gold fields and practical guiding significance in the new round of "exploring deep deposit" work. |
