Aragonite has come from Austria in a Siderite
mine in Eisenerz, Styria (mainly in the Flos Ferri
variety), and in the salt mines of Salzburg. The old iron mines at Frizington, Cumbria, England; as well as the locality of Vitosov, Moravia, Czech Republic; have both been good specimen producers.
A recent producer of specimen-grade Aragonite is Liupanshui, Guizhou Province, China. One of the most prolific occurrences for this mineral, in large trillings and in aggregate
s of reddish-brown crystals, is the Tazouta Mine near Sefrou, Morocco.
In the U.S., New Mexico has provided many fine Aragonite specimens at the Kelly Mine, Magdalena, Soccoro Co.; at Lake Arthur, near Roswell, Chaves Co; and at Las Cruces, Dona Ana Co. Fine Aragonite has also come from Bisbee, Cochise Co., Arizona; the Grand Deposit Mine, White Pine Co., Nevada; and the Northern Lights Mine, Hussman Spring, Mineral Co., Nevada. Other Western occurrences are Morro Bay, San Luis Obispo Co., California; the Oquirrh Mountains, Tooele Co., Utah; and Fort Collins, Larimer Co., Colorado. Midwestern and Eastern localities include Cave-in-Rock, Hardin Co., Illinois; Sterling Hill, Ogdensburg, Sussex Co., New Jersey; and Paterson and Prospect Park, Passaic Co., New Jersey.
