| 摘 要： | 老厂矿床的矿物组成、矿物组合、矿石结构构造、成矿期次、矿物生成顺序、成矿分带及银的赋存状态等特征表明，该矿床主要形成于火山热液期，并划分为３个成矿阶段：铜硫阶段、银铅锌阶段和砷金阶段．银主要以辉银矿－螺状硫银矿的形式沿方铅矿解理是叶片状分布。

| Abstract: | The mineralogical composition, mineral assemblages, ore textures and structures,minerogenetic stages, forming sequence of minerals, minerogenetic zonation and existing states of silver of Laochang ore deposit are discussed in detail in this paper.It is considered that the ore deposit is mainly formed in volcanic hydrothermal period, and it may be divided into three minerogenetic stage: copper-sulfur stage, silver-lead-zinc stage,arsenic-gold stage. The silver is principally existed in cleavages of galena as foliated argentite-acanthite. |
