Igneous rock forming
WebIgneous rocks are usually formed from the cooling or hardening of magma within the Earth’s crust. Granite is an intrusive igneous rock usually formed at subduction zones near continental plate limits, therefore, granite is known as a plutonic rock. Granite is formed at temperatures needed to melt rock of at least 700 °C. WebGranite is an igneous rock made up of primarily quartz, feldspar, micas, amphiboles, and a mixture of additional trace minerals. These minerals and their variation in abundance and alteration give granite the numerous colors and textures we see in granite countertops.
