Where does slate come from.
Shale is a fine grained rock made from compacted mud and clay.
Black and gray shale are common but the rock can occur in any color.
Some other rocks that occur in thin beds are improperly called slate because they can be used for roofing and similar purposes.
Slate is a foliated metamorphic rock with fine grains.
True slates do not as a rule split along the bedding plane but along planes of cleavage which may intersect the bedding plane.
It is popular for a wide variety of uses such as roofing flooring and flagging because of its durability and attractive appearance.
Slate is a fine grained foliated homogeneous metamorphic rock derived from an original shale type sedimentary rock composed of clay or volcanic ash through low grade regional metamorphism it is the finest grained foliated metamorphic rock.
Shale is the most common sedimentary rock accounting for about 70 percent of the rock in the earth s crust.
Foliation may not correspond to the original sedimentary layering but instead is in planes perpendicular to the direction of metamorphic compression.
These rocks are typically dark grey but could also be orange red black and light grey.
