 abstract={A peralkaline granite of the Ilímaussaq Complex, South Greenland, contains the rare mineral henrymeyerite [(Ba0.92Na0.05Ca0.03)1.0(Ti6.87Fe2+1.04Nb0.03)7.9O16], a low-Fe Ba titanate [(Ba0.74Ca0.02Na0.05)0.8 (Ti4.9oFe2+0.15 Nb0.04)5.1O11], and an unidentified Ba titanosilicate. Both titanates show the coupled substitution 2Na+ + Si4+ → Ba2+ + Ti4+. The minerals are present as tiny crystals fringing ilmenite inclusions in an amphibole crystal and are thought to have formed during the hydrothermal stage of the granite’s evolution.},
