The Huronian glaciation followed after the Great Oxygenation Event (GOE), a time when increased atmospheric oxygen decreased atmospheric methane. It is the oldest known ice age, occurring at a time when in biological sense, only simple, unicellular life existed on Earth. == Name origin == This geological era was named from geologic findings in the Lake Huron region in North America where three separate horizons of glacial deposits are separated by non-glacial sediment. 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「Huronian glaciation」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.
