About: Bavenite

An Entity of Type: mineral, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Bavenite is a calcium beryllium aluminosilicate, and it is a part of the Bavenite- series. Its name originates from its type locality, which is Baveno, Italy. This mineral is approved by the IMA, and got grandfathered, meaning it is still believed to refer to a valid mineral species. It was discovered in 1901 in a pink granite mined in Lago Maggiore. When bavenite was discovered, it was considered as a member of the zeolite series. Later it was removed from the series as unlike zeolites, bavenite loses the water stored in its crystal lattice in a way higher temperature, between 210 and 320 °C. It is a cheap mineral considering its rarity.
