Limestone composition

Limestone can be in different colors depending on the material composition (amount of iron, magnesium, dolomite, and other impurities) that it contains. However, most limestone rocks are light to dark gray in color with red or yellow streaks and spots on them. Limestone has poor mechanical strength, especially when compared to marble.

Modified date: 27/08/2023. Granite is the most common intrusive rock in Earth’s continental crust, It is familiar as a mottled pink, white, gray, and black ornamental stone. It is coarse- to medium-grained. Its three main minerals are feldspar, quartz, and mica, which occur as silvery muscovite or dark biotite or both.

The mineral compositions of igneous rocks are usually described as being felsic, intermediate, mafic, or ultramafic (as examples, see Figure 4.7 and Figure 4.8). Felsic rocks are made of light-colored, low-density minerals such as quartz and feldspar. Mafic rocks are made of dark-colored, higher-density minerals such as olivine and pyroxene.Composition. Limestone is made of calcium carbonate. Dolomite is made of calcium magnesium carbonate. Age and Formation. Throughout the last billion years, much of Alberta was covered by an ocean. The ancient lime-rich ocean sea floor and coral reefs are preserved as limestone and dolomite. Unmonitored usage of limestone may cause conditions such as gas and bloating in the stomach. An excess amount of calcium in the body is harmful to the kidneys. Certain people may experience signs of kidney damage such as alteration in the amount of urine. This side effect is very rare with the use of liemstone.The climate of the source area can also influence composition. Most breccias are a mix of rock fragments and mineral grains. The type of rock that the fragments were produced from is often used as an adjective when referring to the rock. Some examples: sandstone breccia, limestone breccia, granite breccia, chert breccia, basalt breccia, and others.
