Explanation

Also known as vitreous structure. It is the structure of rock composed of all the amorphous volcanic glass. As the magma eject out of the earth's surface, it cools quickly, so that the atoms or ions in it can't be combined in order to form regular crystalline materials, and then it solidifies to form glass state materials. glass is dense with glass luster and shell shaped broken door. There is no optical characteristic of crystal under the orthogonal polarizer, so it is different from aphanitic. glass is unstable and undergoes devitrification or crystallization with changes in time, temperature, and pressure? transformation into crystalline substance. vitreous texture is the feature of volcanic rock with a relatively new geological age.
