深色天然烟晶中内含物的成因及其鉴定意义

Study on Genesis of Inclusions in Dark Smoky Quartz and Its Identification Significance

以颜色成因机理为依据,对深色天然烟晶中的雾状包裹体进行了研究,对其成因进行了探讨,认为形成这种雾状内含物需存在三个条件,是天然水晶,富含Al(Ⅲ),经过人工辐照处理。经红外光谱仪的验证,这种雾状包裹体可以作为深色天然烟晶(经人工辐照处理)的常规鉴定依据之一。

On the basis of formation mechanism of color, the fog-like inclusion in dark smoky quartz has been studied. The paper puts forward that the fog-like inclusion is formed under three conditions: natural quartz, abundant Al(Ⅲ)and irradiation-treated . Proved by infra-red spectrometric analysis, the fog-like inclusion can be one of the criteria for routine identification of natural dark smoky quartz (irradiation-treated).
