“绵柳”一词是我国宝玉石业人士对宝玉石内部结构中的一种“细长丝柳状、绵絮状”结构现象的笼统的俗称。笔者认为,绵柳不属于包体范畴,而是一种内部结构现象。包体与绵柳的区别: 包体是矿物形成过程中,由于内部的物理、化学条件不同,所造成的晶格缺陷被另一种物质所充填,由此而形成的一种独立于主矿物本身的物质形态。它的本质特征是:物理、化学性质和赋存形式独立于载体矿物。
The term “cotton willow” is a general term used by the gemstone industry in China to identify a kind of “thin filament-like, foamy-like” structure in the internal structure of gemstones. I believe that cotton willow does not belong to the category of inclusions, but an internal structure of the phenomenon. The difference between the inclusion body and the cotton willow: The inclusion body is a mineral formation process, due to the internal physical and chemical conditions, the resulting lattice defects are filled with another substance, resulting in a separate from the main mineral Its own physical form. Its essential characteristics are: physical, chemical properties and forms of occurrence independent of the carrier minerals.
