The degree of fineness or coarseness of rocks is referred to as texture. Texture is one of the properties used to describe rocks and is determined by the size, shape, and arrangement of mineral grains or crystals in the rock. Texture is an important characteristic of rocks as it provides information about the conditions under which the rock was formed and the subsequent geological processes that have affected it. For example, a fine-grained texture may indicate rapid cooling of molten rock, while a coarse-grained texture may indicate slow cooling or the presence of larger mineral crystals.
