|Summary:||Lanthanite-(Ce) ((Ce,La,Nd)2(CO3)3.8H2O, with Ce > La,Nd; Pbnb, a 9.482(6), b 16.938(11), c 8.965(3) A, Z = 4, D(calc) 2.79, D(meas) 2.76 g/cm3) occurs as a secondary mineral in oxidized copper ore at the Britannia mine, Snowdonia, North Wales. It is found as colourless transparent plates (010) covered by radiating tufts of malachite and is associated with brochantite, posnjakite and chalcoalumite. The strongest XRD lines are 8.47(100), 3.255(73), 4.746(65), 3.028(65) and 4.462(62) A. The mineral is biaxial negative, alpha 1.532(2), beta 1.594(2), gamma 1.616(2). It is not fluorescent, and has H. 2.5, a colourless streak, a vitreous lustre and is sectile. [J.A.Z.]|
