    中安第斯地区蒸发岩矿床成矿作用特征及构造背景

    Metallogenic characteristics and tectonic setting of evaporite deposits in Central Andes

    • 摘要: 在中安第斯高原,包括玻利维亚西部、智利东部、阿根廷北部分布众多的盐湖,湖中含丰富的B、K、Li、Mg和其他蒸发盐类物质,封闭的盆地因蒸发作用使残留盐水中的成矿元素聚集并沉淀。这些矿床的形成与安第斯山的隆起和气侯变化关系密切。通过对该区蒸发岩型矿床的分布特征及成矿特征进行研究,讨论其形成的构造背景,分析成矿要素和找矿方向。

       

      Abstract: Several salt lakes are distributed in central Andean plateau which includes western Bolivian, eastern Chile, and northern Argentina. These lakes are rich in B, K, Li, Mg and other evaporites. Ore-forming elements experienced accumulation and precipitation after evaporation in the closed basin. The formation of these deposits was closely related to the uplift of Andean and climate change. In this paper, through the research on the distribution characteristics and metallogenic characteristics of the evaporate deposits, the authors discussed the tectonic background, analyzed metallogenic elements and proposed the prospecting direction.
