坦布里兹稀土矿是世界最大稀土矿床之一，位于格陵兰南部的库雅雷哥自治区。 坦布里兹稀土矿为澳大利亚勘探家格雷格·巴恩斯（Greg Barnes）领导的团队所勘探发现。
The Tanbreez project area is favorably located in Southern Greenland.Outcropping ore body known as Kakortokite covers an area of 8 x 5 km and is approximately 400m thick. It is believed to underlie another 42 km2 within the licensed boundary.Tanbreez is unique amongst the rare earth projects in that none of the minerals, ore, concentrate or waste is in any way toxic. All have shown,after extensive testing, to be inert.
坦布里兹为与碱性侵入岩有关的稀有（铌钽锆铪）-稀土-稀散（镓）矿床，主要矿物组份为长石-异性石-钠铁闪石。
