Golden Color Culture Stone

Golden Color Culture Stone

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. ... It may mean a single roofing tile made of slate, or a writing slate.

What is Slate?

Slate is a fine grained and foliated type of metamorphic rock. It owes its fine grained texture to its parent rock, shale. Shale, a type of sedimentary rock, consists of dominantly clay-sized particles (in geology, clay is a reference to particle size, not a reference to any resemblance to artist's clay), which create a smoother, finer grained texture when exposed to low grade metamorphic conditions. Slate can occasionally form as a result of metamorphism in volcanic ash deposits, although this is not as common as the shale-derived rocks. It also exhibits foliation, or layering, which again, is a result of the parent rock being subjected to metamorphism.

Mineralogy and Petrology of SlateSlate is a very strong and durable rock, due largely to its metamorphic history, and as a result has a variety of uses in construction and industrial applications. The majority of the world's slate is mined in Spain, Brazil, the northeastern United States, and in recent years, China.

In terms of its mineral composition, slate is comprised primarily of quartz and mica minerals, including muscovite, illite, and/or biotite. It can also contain chlorite, hematite, or pyrite.

The color of slate is determined by the color of the minerals its parent rock (shale) contained, and can vary from shades of green (chlorite-rich), to red (hematite-rich), to gray/black (biotite-rich). There are also intermediate colors that are sometimes found, including red-browns, green-blacks, and even occasionally shades of purple in certain parts of the world.

As previously mentioned, it gets its fine grained texture and foliation from a combination of its parent rock, shale, and its exposure to metamorphic conditions. The combination of shale and metamorphism leads to a unique type of foliation known as slaty cleavage, which is a fancy way of saying that slate's surfaces break (cleavage) in a way that is unique to slate. It is an identifying characteristic for slate in the field. It is this cleavage that also allows it to have such nice, flat surfaces that are so desired in the building and construction industries for use as roofing tiles or flooring.
