翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Cymrite ： ウィキペディア英語版 Cymrite Cymrite is a silicate mineral with the chemical formula BaAl2Si2(O,OH)8·H2O.〔 The mineral is named for Cymru, which is the Welsh word for Wales.〔 Cymrite, with perfect cleavage and a monoclinic crystalline system, falls in the silicate group.〔 Silicates are formed of Silicon and Oxygen bonding together to form tetrahedra.〔 The symmetry of Cymrite is classified as having a mirror plane. It has a moderate relief, meaning the contrast between the mineral and the epoxy of a thin section makes cymrite easily visible. The birefringence of the mineral is 0.01.〔 Cymrite, being monoclinic is anisotropic with two optic axes. ==Occurrence== Cymrite was discovered in Wales but is found in other areas throughout the United States, Africa, Greece and other parts of Europe. It occurs in generally high temperature-pressure areas such as the hydrothermal manganese silicate ore that makes up the Benalt Mine in Wales and in manganese rock that has undergone high-pressure metamorphism found in Greece.〔 It is important to geologists because of its limited occurrence, when cymrite is present on a rock it indicates that the rock, at some point, must have experienced high pressure and temperature. 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「Cymrite」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.
