宝石的某些次生内含物特征研究

Study on Characteristic of Some Secondary Inclusions in Gems

宝石在表生风化作用下或开采加工的过程中 ,由于表生铁、锰氧化物质、微细泥沙质、研磨料或抛光粉等的水溶液沿宝石的开放性裂隙扩散、渗透、沉淀 ,在宝石内部形成具有薄膜状、树枝状、叶脉状、网格状、羽状、花瓣状、幔纱状、指纹状、雨滴状、串珠状等内含物 ,其形状与宝石的原生内含物十分相似 ,可根据其产出特征及物质成分的不同而加以区别。

The secondary inclusions in gems, which are formed by the proceeding of weathering, mining, cutting of gems, are related to the diffusing, percolation and precipitation of aqueous solution which contains weathered chemical material, fine silt, grinding and polishing abrasive. The shapes of the secondary inclusions can be different, such as membrane-like, branch-like, leaf-like, grid-like, feather-like, petal-like, gauze-like, fingerprint-like, raindrop-like, string beads-like, etc, and are similar to proto-inclusions in gems, but can be identified according to the forming characteristics and contents of the inclusion.
