It may also show bedding, which is often strongly distorted. Rock gypsum is usually interbedded with sandstones, marls, and limestones. A soft rock, it can be scratched easily with a fingernail.Crystal varieties Gypsum occurs in nature as flattened and often twinned crystals, and transparent, cleavable masses called selenite. Selenite contains no significant selenium; rather, both substances were named for the ancient Greek word for the Moon . The two characteristics used to classify metamorphic rocks are foliation and lineation. These rocks are identified by the presence of certain mineral types and specific textures.

Classification of Igneous Rocks Textures of Igneous Rocks For igneous rocks, texture refers to the size, shape and geometry of adjacent minerals in a rock. The texture of an igneous rock is predominantly controlled by composition of the magma/lava and the cooling rate (intrusive v. extrusive). This reddish rock is arkose, a young feldspathic sandstone. Andrew Alden / Wikimedia Commons. Arkose is a raw, coarse-grained sandstone deposited very near its source that consists of quartz and a significant proportion of feldspar.. Arkose is known to be young because of its content of feldspar, a mineral that usually degrades quickly into clay.Expert Answer.
