翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Cyanotrichite ： ウィキペディア英語版 Cyanotrichite Cyanotrichite is a hydrous copper aluminium sulfate mineral with formula Cu4Al2()·2H2O, also known as lettsomite. Cyanotrichite forms velvety radial acicular crystal aggregates of extremely fine fibers. It crystallizes in the orthorhombic system and forms translucent bright blue acicular crystal clusters or drusey coatings. The Mohs hardness is 2 and the specific gravity ranges from 2.74 to 2.95. Refractive indices are nα=1.588 nβ=1.617 nγ=1.655. ==Occurrence and discovery== It is an oxidation product of primary copper mineralization in a weathering environment with abundant aluminium and sulfate. Associated minerals include brochantite, spangolite, chalcophyllite, olivenite, tyrolite, parnauite, azurite and malachite.〔 The main deposits are Cap la Garrone in the Var (France), Romania and Arizona (USA). It was first described in 1839 from Moldova Nouă, Banat, Romania. The name is from Greek ''kyaneos'' for "blue" and ''triches'' for "hair" referring to the typical color and habit. Its earlier name, Lettsomite, is taken from the name of William Garrow Lettsom (1804–1887), co-author of the 1858 ''Manual of the Mineralogy of Great Britain and Ireland''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cyanotrichite」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
