In geology, texture or rock microstructure [1] refers to the relationship between the materials of which a rock is composed. [2] The broadest textural classes are crystalline (in which the components are intergrown and interlocking crystals), fragmental (in which there is an accumulation of fragments by some physical process), aphanitic (in which crystals are not visible to the unaided eye ...
Bentonite – Rock type or absorbent swelling clay; Brisbane tuff; Eutaxitic texture – Layered or banded texture in some extrusive rock bodies; Sillar – Variety of rhyolite containing fragments of andesite; Tuffite – Tuff containing both pyroclastic and detrital materials; Ignimbrite – Type of volcanic rock, a type of welded tuff.
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al 2 Si 2 O 5 4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water [1] and have been important to life, and many theories of abiogenesis ...
Clay minerals are almost always mixed with very small amounts of nonclay minerals which can produce intense peaks, even when there is very little of the sample is not a clay. If additional minerals are known to be presents, attempts should be made to separate clays from nonclays otherwise additional peaks should be expected.
Kyber crystals vary in shape and color, but all are deeply connected to the Force, the vast energy field connecting all living things. They are most commonly used by the Jedi and Sith in making lightsabers; but larger, rarer crystals are sometimes used in superweapons, including the planet destroying Death Star. Lerasium Mistborn

A diamond plate texture rendered close-up using physically based rendering principles. Microfacet abrasions cover the material, giving it a rough, realistic look even though the material is a metal. Specular highlights are high and realistically modeled at the appropriate edge of the tread using a normal map.
