Black shale contains a lot of carbon - this is what gives it its black colour. So, when it weathers, it releases carbon as carbon dioxide (a greenhouse gas), which may have an impact on global warming.
Another name for shale is mudstone
Shale is a brown to black rock that is composed of very thin, easily split layers of strata, and the rock's graining on a freshly cleaved surface is so fine that individual grains are not distinguishable with the naked eye.
A rock with a dull color could be shale, which is typically gray, brown, or black in color and has a dull luster. Shale is a fine-grained sedimentary rock that is made up of clay and other mineral particles.
Shale can sometimes contain magnetic minerals, such as magnetite or hematite, which can make it slightly magnetic. However, the magnetic properties of shale can vary depending on the specific mineral content and geological conditions.
Shale normally leaves a brown streak on unglazed porcelain plates. However, shale can also leave a white streak on unglazed porcelain plates.
A black shale is a form of dark muddy rock, which is rich in sulphides and organic material.
Black shale is a very thinly bedded shale rich in sulfides such as pyrite. It is commonly found in anoxic, reducing environments, such as in stagnant water columns.
The value of black shale can vary depending on its quality, location, and market demand. On average, black shale can range from a few dollars to around $50 per ton. It is best to check with local suppliers or mining companies for current pricing.
limestone
Shale in general is the most abundant of stratified rocks. One of the most popular forms of shale used for building roads is called Marcellus Shale. When this clay shale is nearly pure it is known as argillaceous. When it contains a lot of sand it is arenaceous. You will find that shale varies in color, reddish, very black, or grey. Shale is used mainly for top dressing on roads. To have a good road base slate is recommended.
Oil shale rock
yes because of the water and the oxygen and it terns into rust
Hydrocarbon and oil shale
Shale is a noun.
It can be green red black gray brown and yellow. People use it for Oil or natural gas. Shale is the parent rock of Slate. Used for brick ,tile ,pipe ,pottery ,and others.
It can be. It is found in a rock type called shale and is produced in the shale form the original bio mater included in the deposition of the shale. If a unit of shale lithology is to be found on the continental shelf strata then it is likely that that shale will contain shale gas and it will be under the sea.
The Shale is not a metamorphic rock it is a sedimentary rock.
