摘要
滇东南是云南省重要的锑矿产地。矿床可划分为似层状和脉状两种产出形式。根据成矿物质来源、成矿作用方式、围岩和矿石建造、矿床分布特征，属沉积－强烈改造层控矿床。具工业意义的锑矿床只产于一定时代、层位和有利的岩性组合内；成矿物质只在特定的沉积环境中形成；构造是锑矿分布、改造富集的重要条件；硅化蚀变与锑矿化富集密切相关。根据拟建的“地层、岩性、岩相、构造、蚀变”的找矿模式，提出了锑矿找矿的最佳类型和最佳找矿地段。
The important occurrence places of Sb deposits of Yunnan province are in Southeast Yunnan. These Sb deposits can be put into two forms of stratoid and vein-like occurrence.They belong to the sedimentary-intensively transformed stratabound deposit according to the origin of metallogenic material, metallogenesis form, formation of wall-rock and ore,distribution characteristics of deposit. The commercial Sb deposits are only occurred in a fixed period, horizon and favourable lithologic character assemblage; the metallogenic material is merely formed in a specified sedimentary environment; the structure is the important condition of distribution, transformation and concentration of Sb ore; and the Sb metallogenesis concentration is closely correlated with silicification alteration. According to the established ore-prospecting model of 'strata, lithologic charater, lithologic facies,structure, alteration', the best tape and oreprospecting area of Sb deposit are put forward in this paper.
