Several primary inclusions consist of large bubble and glassy material. Multiple bubbles extend through their damage limitation, resulting from its treatment. Besides, there are many negative crystals exploding and draining during this heat treatment, which create a large number of bubbles. Most of the crystals tend to be circular, without sharp edge, displaying blurry outline.

一些原生包裹体在高温处理后形成了特殊组合,由大的气泡及具玻璃光泽的物质构成。许多气泡在高温下膨胀延伸至其损害限度。图片中可见大量负晶包裹体,在处理过程中破裂,流体蒸发流失,从而产生大量气泡。这些晶体外表逐渐圆化,锋利的边缘渐渐消失,只见模糊的轮廓。
