Gypsum & Halite
soem examples of chemical sedimantery rock are limestone, and gypsum.
Some examples of chemical sedimentary rocks include limestone, dolostone, and rock salt. These rocks form when minerals precipitate out of a solution, such as when water evaporates or through processes like precipitation.
What are 2 examples of a Chemical Properties
They are called chemical sedimentary rocks. Rock salt and rock gypsum are two examples.
Sedimentary rocks are formed from the accumulation of particles, which can be either clastic or chemical in nature. Clastic sedimentary rocks are composed of fragments of other rocks and minerals, while chemical sedimentary rocks form from the precipitation of minerals from solution. Both types result from processes like erosion, deposition, and lithification. Examples include sandstone (clastic) and limestone (chemical).

Sedimentary rocks can be formed by chemical reactions when minerals in water precipitate out and settle to form rock layers. Examples of sedimentary rocks formed by chemical reactions include limestone and halite.
Rock salt and rock gypsum are common examples of a group of chemical sedimentary rocks called evaporities. When a sedimentary rock consists of angular, grave sized particles is breccia.
Examples of igneous rocks include granite, basalt, and obsidian. The chemical formula for granite is roughly SiO2 (silicon dioxide), for basalt it's typically SiO2, Al2O3, FeO, MgO, CaO, and for obsidian it's SiO2 with minor impurities giving it a glassy texture.
Chemical or potentially chemical sedimentary rocks form through the precipitation of minerals from solution, often in bodies of water. Common examples include limestone, which can form from calcium carbonate precipitating out of seawater, and evaporites like rock salt and gypsum, which result from the evaporation of water in arid environments. Other examples include dolostone, which can form through the alteration of limestone. These rocks often indicate past environmental conditions such as evaporation rates and water chemistry.
Two examples of weathering are mechanical weathering, such as when rocks are broken down into smaller pieces by physical forces like wind or water, and chemical weathering, which occurs when rocks are broken down by chemical reactions like oxidation or dissolving.
