Granite Stone

Granite is one of the sedimentary rocks that is formed as a result of geological processes and under high pressure and heat. This rock is composed of various mineral materials, the most important of which are feldspar, quartz, and mica. The formation process of granite begins with a magmatic melt. This magmatic melt is transported to the Earth’s surface due to movement and eruption and forms magma chambers beneath the Earth’s crust. In these magma chambers, the magmatic melt is divided into smaller batches and is subjected to high pressures and temperatures at the edges. Over time, these smaller batches of magmatic melt form intrusive layers with different compositions in the depths of the Earth. Various types of granite include white granite, black granite, red granite, and green granite. These differences depend on the mineral compositions present in the rock and their ratios. The minerals that make up granite include feldspar, quartz, biotite, and mica. Feldspars are present as the main minerals in granite, and depending on the ratio of three types of feldspar minerals (plagioclase feldspar, albite feldspar, and feldspar outside the intrusion), the type of granite is determined. Quartz is also found as fine grains in granite and plays an important role in the strength of the rock. Biotite and mica are also present as fine grains in granite and give it special characteristics such as luster and reflectivity. The physical properties of granite include density, hardness, density, color, and its crystals vary. Granite has high density and is hard and resistant due to the presence of quartz and feldspar. Additionally, granite has various colors such as white, gray, red, pink, and green due to its different mineral compositions. The crystals present in granite also contribute to its beauty and luster. Regarding the chemical properties of granite, this rock is composed of silicate compounds, with silicon being the most abundant element. In addition to silicon, granite contains other elements such as aluminum, potassium, sodium, calcium, and iron. Due to the presence of feldspars, granite is not soluble in strong acids and is resistant to weak acids.
