Flannelette, also known as dewstone, is a common volcanic basalt mineral that forms when magma cools and solidifies during volcanic eruptions. It is commonly found in basalt formations on the Earth's crust, but can also be found in more recent bottom sediments in the deep ocean.

The chemical composition of the mess is mainly aluminum silicate calcium magnesium manganese sodium titanium iron magnesium manganese chlorinated volcanic rock, its crystal structure is trigonal crystal system. The characteristic of the mess is that its cells are relatively complex, and there are multiple channels of different sizes inside, which can accommodate the presence of water molecules. This is also one of the sources of the name of the mess, because when it encounters water particles, it will adsorb in its own channel, forming the structure of hydration mess.

The appearance of the velvet is characterized by black to dark olive green, blocky or granular. Its surface is often covered with small granular structures, these granular structures are called the granular shell. The granular shell is mainly composed of iron oxide, ferruginite, olivine and other minerals, and has a rough texture.

Flaps can appear as patches, blocks, or layers in basalt formations. In the study of geology, the existence of tangles is often related to the formation and change of the crust. The cause of the mess is the result of magma cooling crystallization, when the minerals in the magma filled the void in the magma and gradually cooled and solidified, the mess is formed.

Flannelette also has special physical properties. First of all, flannery is a strong magnetic mineral that shows significant magnetization to magnetic fields. Secondly, the color of the pile changes with the change of light, showing different colors at different angles, which is caused by the composition and structure of its granular shell. In the end, the mess also has a certain conductivity, can conduct current.

Flannelette has certain application value in industry. Due to its unique physical properties, flaps are an important filling material, often used in high temperature furnace insulation and insulation materials. In addition, the mess velvet can also be used for the preparation of refractory materials, which can improve the heat and chemical resistance of the material.

Mess velvet is also a common gem rough stone, often used in gem processing and production. Its unique granular shell structure and color changing properties make it one of the important materials for jewelry and decoration production.

In short, flanges is a common volcanic basalt mineral with special chemical composition and physical properties. It has important applications in geology, industry and gemstone processing. Through the research and application of twill, we can better understand the earth's geological structure and resource formation process, but also can provide important materials for industrial production and gem processing.
