(詳細はmineral that contains one or more rare earth elements as major metal constituents. Rare earth minerals are usually found in association with alkaline to peralkaline igneous complexes, in pegmatites associated with alkaline magmas and in or associated with carbonatite intrusives. Perovskite mineral phases are common hosts to rare earth elements within the alkaline complexes. Mantle-derived carbonate melts are also carriers of the rare earths. Hydrothermal deposits associated with alkaline magmatism contain a variety of rare earth minerals. The following includes the relatively common hydrothermal rare earth minerals and minerals that often contain significant rare earth substitution: *aeschynite *allanite *apatite *bastnäsite *britholite *brockite *cerite *fluocerite *fluorite *gadolinite *monazite *parisite *stillwellite *synchysite *titanite *wakefieldite *xenotime *zircon ==Production== The mining of rare earth minerals was at one time dominated by the United States. The People's Republic of China has since come to dominate the market. 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「rare earth mineral」の詳細全文を読む スポンサード リンク
