| 中文摘要:华南锑矿带是我国乃至世界上最重要的锑成矿带,分布有众多大型-超大型单锑型锑矿床。本文以滇东南木利锑矿床作为主要研究对象,并与华南锑矿带内单锑型矿床中最典型的锡矿山和独山锑矿田(床)进行详细的基础地质特征对比研究。发现对于单锑型锑矿田(床)而言,无论是矿田尺度还是矿床尺度,普遍具有“石英-辉锑矿”和“方解石-辉锑矿”两种类型矿物组合。同一矿田内,部分矿床(段)以“石英-辉锑矿”的矿物组合为主,部分以“方解石-辉锑矿”的矿物组合为主；而矿床(段)尺度内,又往往表现为上部“石英-辉锑矿”型矿物组合,下部为“方解石-辉锑矿”型矿物组合的两层楼模式。该模型的提出对于华南锑矿带单锑型矿床成因研究和找矿勘查具有重要意义。 |

| The “two-story binary metallogenic model” for the pure stibnite deposits in the South China antimony ore belt: A case study of the Muli antimony deposit in southeastern Yunnan Province |

| Abstract:The South China antimony ore belt, which is composed of lots of large-super large pure stibnite deposits, is the most important antimony metallogenic belt in China and even in the world. In this paper, the Muli antimony deposit in southeastern Yunnan province, is taken as a main research object, through the detailed comparative study of basic geological characteristics with the typical Xikuangshan and Dushan antimony ore fields (deposits) in the South China antimony ore belt. We can find that no matter in ore field or deposit scale for the pure stibnite ore field (deposit), two types of mineral assemblages may occur, “quartz-stibnite” and “calcite-stibnite”. In the same ore field, some deposits (sections) show “quartz-stibnite” mineral assemblage, while some show “calcite-stibnite” mineral assemblage. On the other hand, the “quartz-stibnite” mineral assemblage usually located in the upper part, and “calcite-stibnite” mineral assemblage located in the lower part when they contemporaneously exist in one deposit. Such model is first named as “two-story binary metallogenic model” in this paper, which is of great significance for the study of genesis and prospecting of pure stibnite deposits in South China antimony ore belt. |
