Granite general, descriptive field term for lighter-colored, coarse-grained igneous rocks. Petrographic examination is required for identification of specific types of granitoids. The extrusive igneous rock equivalent of granite is rhyolite. Granite is nearly always massive (i.e., lacking any internal structures), hard, and tough. These properties have made granite a widespread construction stone throughout human history. The average density of granite is between , its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6·10 Pa·s. The melting temperature of dry granite at ambient pressure is ; it is strongly reduced in the presence of water, down to

Granite Rock Company of Watsonville, California purchased the property and mineral rights to a large deposit of white limestone on Mount Pico Blanco in the Los Padres National Forest on the Big Sur coast of California in 1963. The limestone deposit is made up of two large, pharmaceutical grade limestone bodies known as the Pico Blanco body and the Hayfield body. It is the only high-grade deposit on the Pacific Coast outside Alaska within three miles of potential marine transportation. Reserves have been estimated to be from 600 million to a billion tons, reportedly the
