目前，对小秦岭金矿的成因有三种观点：岩浆热液、变质热液和大气降水热液，这三种观点均有许多难以解释的地质现象。这些矛盾的出现表明，可能有另种矿床成因的存在。笔者在此提出了由上地幔或下地壳物质向深断裂带排气液作用形成的＂深源热液＂新观点。该观点能很好地解决上述观点难以解决的地质问题。 At present, there are three viewpoints on the genesis of the Xiaoqinling gold deposit: magmatic hydrothermal fluids, metamorphic hydrothermal fluids and atmospheric precipitation hydrothermal fluids, all of which have many unexplained geological phenomena. The emergence of these contradictions shows that there may be other causes of deposit existence. Here, I propose a new viewpoint of “deep source hydrothermal solution” formed by the action of the upper mantle or the lower crust to the deep fault zone. This view can well solve the above problems difficult to solve geological problems.
