摘要
四川大水沟碲矿床是世界首例独立碲矿床。通过对其进行矿床地质、常量与微量元素、矿物包裹体地质及稳定同位素测试分析研究 ,认为该矿床成矿物质具有多源性 ,且不同矿化期的成矿元素、成矿流体来源亦不相同 :主成矿期 Te主要源于地幔岩浆脱气 ,少量来源于基性岩或大理岩 ,S可能主要源于早期形成的磁黄铁矿 ,Bi可能与中酸性、基性岩浆有关 ;成矿流体主要为岩浆气液。
Through researches on the ore geology, major and minor elements, fluid inclusions and the isotopic analyses of the Dashuigou Te deposit, the authors believe that the materials of this deposit are of multi-sources and that the sources of ore-forming elements and fluid in the different mineralization epochs are also different. In the main mineralization epoch, Te is principally born of the gas-freeing from mantle magma, a little of basic rock or marble; S might be mainly born of pyrrhotite formed in the early epoch; Bi may be in relation to mid-acidic and basic rocks; and Te-rich fluid might be principally from magmatic gas-solution.
