Organic
Coal is primarily made of organic material that has been subjected to heat and pressure over millions of years. It is formed from the remains of plants that have been buried and compressed.
Tufa is a clastic chemical sedimentary rock formed by the precipitation of calcium carbonate from water. It is not organic in origin, as it is created through inorganic chemical processes rather than from the remains of living organisms.
Basalt is a type of igneous rock that is formed from the cooling and solidification of lava. It is considered a chemical sedimentary rock, as its minerals crystallize directly from magma and do not involve the accumulation of organic or clastic material.
It doesn't really have one. Coal is a complex mixture of organic compounds with traces of inorganic and metallic ones too.
Coal is not considered a mineral because it is organic in nature, formed from the remains of plants. Unlike minerals, which are inorganic and have a crystalline structure, coal does not have a consistent chemical composition or crystal structure. This distinction classifies coal as a sedimentary rock rather than a mineral.
clastic
It is clastic
Coal is primarily made of organic material that has been subjected to heat and pressure over millions of years. It is formed from the remains of plants that have been buried and compressed.
It is none of these. Clastic, organic, and chemical are terms for classifying sedimentary rock. Rhyolite is igneous.
None of the above. These terms describe sedimentary rocks. Granite is igneous.
chemical
Bituminous is not clastic, as clastic refers to sedimentary rocks composed of fragments of pre-existing rocks. Bituminous, on the other hand, is a type of coal formed from the compression and heating of organic matter.
Conglomerate is a clastic rock. They are coarse-grained sedimentary rocks.
The two main types of sedimentary rocks are clastic (detrital) rocks, which are made of pre-existing rock fragments cemented together, and chemical rocks, which form from minerals that precipitate out of solution.
