Terrestrial minerals are clastic quartz particles. Some clastic quartz particles contain inclusions, which can be divided into gas-liquid and mineral inclusions. Based on their crystal form, mineral inclusions can also be divided into granular, needle-like, and sheet-like minerals. The type of inclusions is related to the source of quartz. Generally speaking, most gas-liquid inclusions (milky quartz) come from quartz veins; Quartz in schists and other high-grade metamorphic rocks has rare gas-liquid inclusions; The quartz in volcanic rocks is often as clear as water and rarely contains inclusions; Most of the rutile acicular inclusions come from granite.
