- Arizona flagstone
Arizona Flagstone is composed of rounded grains of
quartz which are cemented bysilica . Other minerals are present, mostly as thin seams of clay, mica, secondary silicam calcite, and gypsum. Arizona Flagstone is mainly quarried from the Coconino andPrescott National Forest .At the present time, production from the popular Coconino or "Arizona Flagstone" dominates the stone industry in
Arizona . It probably accounts for 75 percent of both tonnage produced and dollar volume of sales.Although flagstone and dimension stone are quarried from all over the state the town of Ash Fork, AZ is well known as the center of production. Extensive outcrops of Arizona Flagstone are found in Mohave, Coconino, Yavapi, Navajo, Apache, and Gila Counties.
According to the USGS, U.S. flagstore production in 2005 was 146,000 metric ton worth $13.7 million, and of this 121,000 metric tons worth $9.75 million was made of
sandstone .External links and References
