One person rolls on a perlite primer which is mixed with sand while the second creates an arched patterns. The origin of a rock can often be detected from its texture—the sizes and orientations of its mineral or rock fragment components.Most extrusive rocks are fine grained, meaning their mineral components (grains) are less than 1 millimeter in diameter.Lava flow rocks typically have a chilled margin that is very fine grained, or aphanitic. Textures. Two main natural textural groupings exist for sedimentary rocks: clastic (or fragmental) and nonclastic (essentially crystalline). The size and shape of the mineral grains or crystals and the pattern of their arrangement give a texture to the rock. They are Aphanitic, Phaneritic, Pegmatitic, Porphyritic, Vesicular, Pyroclastic, and Glassy.

For sand-silt-clay mixtures and gravel-sand-mud mixtures see Figure 3.1. Texture of a rock is the appearance of the rock and how one feels touching it. Texture refers to the physical makeup of rock—namely, the size, shape, and arrangement (packing and orientation) of the discrete grains or particles of a sedimentary rock. There are basically seven types of igneous rock textures. Texture a ceiling is probably much cheaper than installing beadboard, but it is not a piece of cake. Orthophyric texture is another type of equigranular texture, which is in between the granitic and felsitic textures.

The many igneous rock textures are simply variations on or modifications of this principle. Even if a complex assemblage is not identifiable at the wellsite, a combination of minerals and textures should allow the rock to be characterized. Intrusive rocks are characterized by large crystal sizes, i.e., their visual appearance shows individual crystals interlocked together to form the rock mass.
