| 摘 要： | 摘 要] 祁连山中段托勒山岩金多分布在奥陶纪火山岩地层内，地层控矿特征十分明显。区内与火山活动有关的成矿作用主要是火山喷发后期火山热液形成的热液型矿床，其次是后期岩浆活动提供热源和大量的岩浆热液交代、充填形成中低温热液矿床和接触蚀变型矿床。从找矿前景上来看，本区虽然金矿点、矿化点分布较多，但少有规模较大的矿床。因此本区找矿上应该以寻找火山热液蚀变型矿产为主。

| Abstract: | Abstract: The rock gold in the Tuole area, the middle section of the Qilian Mountains, is mainly hosted in the Ordovician volcanic rocks of this area, and shows a significant control by strata. The mineralization related to volcanism in this area is mainly hydrothermal ore deposits formed by volcanic hydrothermal fluids in the late period of volcanic eruption, and mid-low temperature hydrothermal deposits and contact alteration ore deposits formed by metasomatism and filling with material sources from the late period of magmatic activities. Viewed from prospecting prospect, it is clear that although there are many gold ore occurrences and mineralized distribution spots in this area, only a few large-scale ore deposits are found. The effort of ore-search in this area should focus on volcanic hydrothermal alteration type deposits. |
