They are rocks formed from lava at or near the surface. Basalt is a typical fine-grained extrusive igneous rock, composed of mineral crystals that require magnification to see. The fine-grained texture is due to rapid solidification of the lava which leaves little time for large mineral crystal formation.
A dark fine-grained rock is typically referred to as basalt. It is an igneous rock that forms from the rapid cooling of lava at or near the Earth's surface. Basalt is often dark in color due to its high iron and magnesium content.

If a granite rocks was made of smaller crystals if would be called?
If a granite rock is made of smaller crystals, it would be called fine-grained or fine-grained granite.
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
What is the size of crystals in an igneous rock called?
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
Is diorite a coarse grained rock?
Yes, diorite is a coarse-grained igneous rock that typically contains a mixture of light and dark minerals. It forms from the slow cooling of magma deep within the Earth's crust, resulting in visible crystals that are larger than those in fine-grained rocks.
Basalt is an example of a n?
Basalt is known as a type of rock. This rock is a dark-colored and fine grained.
What does basalt?
A dark fine-grained volcanic rock that sometimes displays a columnar structure
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
What is meaning the grain of the rock?
fine grained or coarse grained
What is an andesite?
a dark, fine-grained, brown or grayish volcanic rock that is intermediate in composition between rhyolite and basalt.
If a granite rocks was made of smaller crystals if would be called?
If a granite rock is made of smaller crystals, it would be called fine-grained or fine-grained granite.
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Is rock smooth or rough?
Metamorphic rock can be coarse grained or fine grained.
Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
Is quartzite rock fine grained course grained or medium grained?
Coarse
How does fine grained igneous rock form?
when the lava cools quickley it is fine-grained
If there are small crystals in a rock what is it called?
The rock is said to have a fine-grained texture, also referred to as an aphanitic texture.
