Pink granite is a type of igneous rock that is primarily composed of quartz, feldspar, and mica. Its distinctive pink color comes from the presence of potassium feldspar, which gives it a warm hue. This durable stone is commonly used in construction and landscaping due to its strength and resistance to weathering. The formation of pink granite occurs deep within the Earth's crust, where magma cools slowly, allowing large crystals to develop. It is often found in regions with a history of volcanic activity. Notable examples of pink granite can be seen in structures like the Texas State Capitol and the Bunker Hill Monument.
