Description
Summary:Orthojoaquinite-(La) from Ilímaussaq, Greenland, is a new member of the joaquinite group. Its description was published by Semenov et al. (1967); although the chemical analytical data indicated that La is the dominant REE in the mineral, its true position in the group was not established for a third of a century. Orthojoaquinite-(La) is orthorhombic, probable space-group Ccmm, a
