Kimberlites are a class of igneous rocks commonly associated with diamond mining. Before the advent of modern geophysical probes, the ideal way to find a kimberlite pipe was to search for "yellow ground", a layer of oxidized kimberlite which is a deep tawny yellow. "Blue ground" was regarded with scorn during the South African diamond rushes, and one of the central characters in the initial diamond rush, Barney Barnato, made his fortune by purchasing digs in which the "blue ground" was all that remained. ==External links== *(Aerial view of Jagersfontein, South Africa showing blue kimberlite from kimberlite hole (mine) ) *(Aerial closeup view of open pit Mir Mine near Mirny in Sakha Republic, Siberia ) showing top yellowish layer and bluish ground further down 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「Blue ground」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.
