Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. It is popular for a wide variety of uses such as roofing, flooring and flagging because of its durability and attractive appearance.

What is an example of fine grained rock?
Slate
What is an example of a fine-grained metamorphic rock?
Slate
What is A fine grained sedimentary rock that forms slate when under extreme heat?
Shale.
What are some examples of a fine grained rock?
Chert, mudstone, shale, slate, precipitated limestone.
Is Slate formed from Granite?
Slate is not typically formed from granite. Granite is a coarse-grained intrusive igneous rock, while slate is a fine-grained foliated metamorphic rock. Slate is often formed from shale or mudstone through low-grade metamorphism, where the minerals in the original rock recrystallize and align to create the characteristic foliation of slate.
What type of texture does slate rock have?
Slate rock has a fine-grained texture, with individual mineral grains that are too small to be seen with the naked eye. This gives slate a smooth and dense appearance.
Is slate harder than shale?
Yes, slate is harder than shale. Slate is a fine-grained, foliated metamorphic rock that has undergone more intense heat and pressure than shale, a fine-grained sedimentary rock. As a result, slate is more durable and resistant to erosion compared to shale.
Is slate an ore?
Slate is not an ore; it is a metamorphic rock.
What is the original name for a slate rock?
The original name for a slate rock is "argillite." It is a fine-grained, foliated metamorphic rock that is commonly used for roofing and flooring due to its durability and water resistance.
Is slate magnetic?
No, slate is not magnetic. Slate is a fine-grained, foliated metamorphic rock that is formed from the compression of mudstone and shale. It does not contain magnetic minerals that would make it magnetic.
The splitting of slate into layers illustrates its?
Slate is a fine-grained gray, green, or blue metamorphic rock that is easily flattened. The splitting of slate into flat layers illustrates its foliation.
What type of rock are blackboards made of?
Blackboards are typically made of a type of rock called slate. Slate is a fine-grained metamorphic rock that is easily split into thin, smooth sheets, making it ideal for writing on with chalk.
