翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Frostwork ： ウィキペディア英語版 Frostwork Frostwork is a type of speleothem (cave formation) with acicular ("needle-like") growths almost always composed of aragonite (a polymorph of calcite) or calcite replaced by aragonite.〔Hill, C. and Forti, P. (1997), ''Cave Minerals of the World'', National Speleological Society, 2nd Edition.〕 It is a variety of anthodite. In some caves frostwork may grow on top of cave popcorn or boxwork. ==Formation== The origin of frostwork is somewhat controversial. Formation of cave frostwork has been attributed to moist, circulating air which, containing dissolved calcium carbonate, drifted against rock surfaces and coated them with the delicate crystals. Frostwork has also been attributed to water seepage from cave passageways in which there are relatively high evaporation rates. 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「Frostwork」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.
