    Igneous Rocks: Texture and Classification | Geology

    Igneous rocks in which all the minerals are present in practically uncrystallised form or glass due to very rapid cooling are grouped as glasses. These may be defined as rocks of zero grain size. The material of the rock had no time to differentiate into individual grains or crystals. Glasses are sometimes referred as supercooled liquids.
