With neodymium being the most strongly coloured trivalent lanthanide, that level of neodymium can occasionally dominate the colouration of rare earth minerals, when competing chromophores are absent, and provide a pink coloration. Outstanding examples of this include monazite crystals from the tin veins of Llallagua, Bolivia. text/html 2011-01-07T14:30:08+00:00 Anonymous (anonymous@undisclosed.example.com) https://xxn.org.uk/doku.php?id=rare_earths:tantalum&rev=1294432208 General Minerals Corp has been focused in the Agua Dulce claim block within the La Bella District, a historic pegmatite-associated tantalum, niobium and mica-producing district located approximately 50 km east of the town of San Ramon and approximately 150 km NE of the major Bolivian city of Santa Cruz. text/html 2011-01-30T10:43:23+00:00 Anonymous (anonymous@undisclosed.example.com) https://xxn.org.uk/doku.php?id=rare_earths:what&rev=1296405803 ©Avalon
