Type Locality Mineral Gallery - August 19

marcus — Fri, 20 Aug 2010 04:59:46 +0000

Every mineral has a type locality, where the first specimens originated. Some type localities are lost to history, such as those for cinnabar or quartz. Now and for the last two centuries, researchers have dutifully recorded type localities for new species. Sometimes a type locality remains the only locality known for a species, such as for keyite, hubeite, and skorpionite seen here, but often as time passes, species turn up at other localities. For instance, only in 2010 has a second world occurrence of szenicsite come to light since its original description in 1994. These type localities seen below represent minerals described in the 19th, 20th, and 21st centuries, including the early example of zincite in 1810. There are minerals from six continents here, showing the diversity of the mineral kingdom.
