What is a term that describes an igneous rock texture in which crystals are present but are not visible?
A term that describes an igneous rock texture with crystals that are present but not visible would be aphanitic. This texture indicates that the individual mineral grains are too small to be distinguished with the naked eye.
What are granite and basalt?
Both are igneous rocks, formed from the cooling and solidification of magma. Granite is a felsic, intrusive igneous rock, with visible well mixed mineral crystals. Basalt is a mafic, extrusive igneous rock, composed of darker mineral crystals, most of which are not distinguishable without the aid of magnification.
What igneous rock is aphanitic texture?
These are igneous rocks that are too fine textured to an extent that there mineral grains or crystalline texture cannot be seen or distinguished with the necked or unaided eyes. They appear or occur as a whole single massive crystalline extrusive body of Igneous origin. Example is Obsidian.
Igneous rocks that have mineral crystals easily seen with the unaided eye formed?
Igneous rocks that have mineral crystals easily seen with the unaided eye formed from slow cooling and crystallization of magma deep underground or at the Earth's surface. The slower the cooling process, the larger the mineral crystals can grow, resulting in rocks like granite and diorite with visible crystals.
Does melted rock that cools quickly result in igneous rock with large mineral crystals?
No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.
What type of igneous rock has individual mineral crystals that are generally too small to be seen without magnification?
geodes
What type of igneous rocks have individual mineral crystals that are too small to be seen without magnification?
Extrusive Igneous Rocks. Basalt (Plankey1995 JF)
What are two extrusive igneous rock that contain crystals?
Basalt and rhyolite both are extrusive igneous rock that contains mineral crystals. However, the mineral crystals are normally less than 1 mm in diameter, and are therefore not discernible without magnification.
What is a mineral with crystals inside?
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.
What igneous rock has crystals that are not visible?
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
The texture of an igneous rock depends on the size and the shape of its what?
mineral crystals
What is Granite crystal?
Granite is an igneous rock with visible mineral crystals.

What size of rock texture refers to igneous rock?
The size of the mineral crystals in an igneous rock determines the rock's texture.
