摘要
以较详细的资料论述了秦岭凤太矿田八卦庙金矿和双王金矿床的主要成矿特征，并对比了两者之间包括成矿地质环境、成矿方式、成矿物质来源和成矿流体等方面的差异。研究表明造成这些差异与两矿床所处的地质环境有关。综合上述特征指出本区泥盆系中的金矿具热水沉积、后期构造岩浆热液多次叠加改造的特点。
Baguamiao and Shuangwang gold deposits are two big typical gold deposits in Feng Tai ore field of Qinling. They are obviously controlled by three main factors: the first is the synsedimentary fault along the northern bundary of the field; the second is the upper Devonian sedimentary basin; the last is the magmatic activity. Comparing Baguamiao gold deposit with Shuangwang gold deposit, It is found that there are many defferences between them, such as the source of metallogenic materials, the ore fluid and the minerogenic way and so on. Which were connected with the ore forming environment of them. Summarizing the described facts.It is considered that all the gold deposit in Devonian system of Fengtai area are charactized by the hydrothermal sediment and the transformation of the later structural magmatic hydrothermal solution.
