What Rock Has Layers But No Crystals. Metamorphic rocks often have a foliated or layered texture that is not typical in igneous rocks. There is little time for crystals to form, so extrusive igneous rocks have tiny crystals (figure 5). Some volcanic rocks have a mixed texture. Cooled lava forms basalt with no visible crystals. They often lack minerals that form plates (such as mica). If no crystals form, the result will be natural glass. Examples of common igneous rock include: Magma that erupts onto the surface is. Igneous rock is formed when a magma cools underground and crystallizes or when it erupts unto the surface of the ground, cools and crystallizes. It has a fine grain structure and is usually black to gray in color. Why are there no visible crystals? Igneous rock may form crystalline structures as it cools, giving it a granular appearance; A rock such as an andesite may have large crystals set within a matrix of tiny crystals.
