Types of sedimentary rocks include:
1- Avar silica is a rock that has been transported and deposited by sedimentation process and has been converted into rock. Like conglomerate, this stone has rounded materials and coarse grains are among the fine-grained materials. Lichens These rocks have less than two microns of granulation. Cuttings In this type of rock, coarse-grained raw materials are among the fine-grained materials.
- Biogenic and organic biochemical sediments are:
Limestones These types of rocks are formed by the deposition of limestone skeletons of living organisms. Abacuses are fine-grained silica deposits of chemical and biochemical origin. Coal and petroleum shales are formed from the remains of ancient living organisms. The building’s limestone is classified according to the standard as follows:
- Low-density building limestone from 1760 to 2160 kg / mm,
- Building limestone with an average density of 2160 to 2560 kg / mm,
- Limestone building with high density, which includes more than 2560 kg / mm.
