阳山金矿位于陕甘川“金三角”的松潘—摩天岭金矿带,为一热液成矿的岩金矿床。区内成矿物质来源较复杂,包括矿区的赋矿地层三河口群和中生代花岗斑岩以及矿区南部的碧口地体;总体上阳山金矿带的成矿流体主要是岩浆水,在成矿晚阶段则有大气降水热液进入;区内多期次的岩浆活动为金矿的形成提供了热源。区内矿源、热源、水源丰富,成矿地质条件优越,符合“三源”成矿模式,具成矿远景。下步应加强对矿区成矿规律的研究,寻找新的矿体,同时布置工程进行验证,进一步扩大矿区的找矿规模。
Yangshan Gold Mine is located in the Songpan-Motianling gold belt of the Shaanxi-Gansu-Hebei Province “Golden Triangle” and is a hydrothermal metallogenic rock-gold deposit. The sources of ore-forming materials in the area are complex, including the Sanhekou Group and Mesozoic granite porphyry in the ore-hosting strata and the Bikou terrane in the southern part of the mines. In general, the ore-forming fluids in the Yangshan gold belt are mainly magmatic water. In the late stage of mineralization, hydrothermal fluid enters the area; and multi-stage magmatic activities in the area provide a heat source for the formation of gold deposits. The ore source, heat source and water source in this area are rich, and the ore-forming geological conditions are superior, which is in line with the “Three-source” metallogenic model and has the prospect of mineralization. The next step should be to strengthen the study of mineralization law, looking for new ore body, at the same time layout of the project for verification, to further expand the ore prospecting scale.
