What else can I help you with?
Rocks that contain crystals that are roughly equal in size and can be identified with the unaided eye are said to exhibit a 'blank' texture?
Coarse grained.
Do all extrusive igneous rocks contain crystals?
No, not all extrusive igneous rocks contain visible crystals. Some extrusive rocks, such as obsidian and pumice, cool so quickly that mineral crystals do not have a chance to form, resulting in a glassy texture instead.
Rocks with visible crystals display what is known as a phaneritic 'blank'?
The display a phaneritic texture.
Do rocks have crystals?
Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.
Metamorphic rocks composed of only one mineral that forms equidimensional crystals have what texture?
The texture of metamorphic rocks composed of only one mineral with equidimensional crystals is called a granular texture. This texture indicates that the mineral grains have crystallized under conditions where there was no preferred orientation of the crystals.
Rocks that contain crystals that are roughly equal in size and can be identified with the unaided eye are said to exhibit a 'blank' texture?
Coarse grained.
Rocks that contain crystals that are roughly equal in size and can be identified with the unaided eye are said to exhibit a texture.?
Coarse grained.
Which igneous rocks exhibit aphanitic texure?
Rocks with an aphanitic texture have fine-grained crystals that are too small to be seen by the naked eye. Common igneous rocks with this texture include basalt, andesite, and rhyolite. These rocks cool quickly at the Earth's surface, preventing larger crystals from forming.
Do rocks that cool slowly from magma contain more crystals?
Yes, rocks that cool slowly from magma have more time for crystals to grow, resulting in a coarse-grained texture with larger crystals. In contrast, rocks that cool rapidly have a fine-grained texture with smaller crystals due to the lack of time for crystal growth.
Do all extrusive igneous rocks contain crystals?
No, not all extrusive igneous rocks contain visible crystals. Some extrusive rocks, such as obsidian and pumice, cool so quickly that mineral crystals do not have a chance to form, resulting in a glassy texture instead.
Do phaneritic igneous rocks contain viewable crystals?
By definition, yes. In contrast, aphanitic rocks do not have visible crystals.
What is nonfoliated texture?
Metamorphic rocks that do not exhibit foliation.
Rocks with visible crystals display what is known as a phaneritic 'blank'?
The display a phaneritic texture.
Do rocks have crystals?
Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.
Do metamorphic rocks contain lectures crystals?
yes
