Metamorphic rocks composed of only one mineral that forms equidimensional crystals have what texture?
They have a non-foliated texture, without banding, non-gneissic; characteristic of marble and quartzite.
Why is coquina classified as an organic rock with with granular texture?
Coquina is classified as an organic rock because it is composed of fragments of shells that come from animals like mollusks. Its texture is rough and granular due to the big shell-like particles.
A soft metamorphic rock composed of the mineral talc?
Soapstone is a metamorphic rock composed of the mineral talc. Soapstone is a non-foliated metamorphic rock with a microcrystalline texture. It is very soft and can be easily scratched.
What do you call the way a rock or mineral feels?

What is oil shales texture?
Oil shale has a fine-grained texture, similar to mudstone or siltstone. It is composed of a mixture of organic matter, clay, and mineral grains.

What are the two features that can help you recognize igneous rocks?
porous surface and a deep red or brown color . some of those rosks are transparent and black with a glassy texture. Answer: Granite has a grainy texture composed of visible mineral crystals. Basalt is usually fine grained with a black or black-green color. Pumice can appear full of small bubbles and will float on water. Volcanic cinders are usually dark red to dark black and appear porous. Obsidian will be black to dark brown and opaque to semi-transparent with conchoidal fracturing.

What is a mineral's texture?
Texture refers to the size of the mineral crystals which comprise a rock.
What texture does a volcanic rock have?
Textures of volcanic rocks include aphantitic (mineral grains are present but microscopic) , porphyritic (some grains are visible to the naked eye), glassy (all or much of the rock lacks a crystalline structure), and vesicular (solidified gas bubbles are present).
