American Mineralogist (1986) 71 (11-12): 1372-1377.
...David C. Smith; Sid-Ali Kechid; Giuseppe Rossi Abstract Lisetite occurs in strongly retrograded clinopyroxene-rich layers in the Liset eclogite pod in the Selje district of the Western Gneiss region, Norway. Electron-microprobe analyses reveal the almost stoichiometric composition Ca-Na 2 Al 4 Si 4...

...Giuseppe Rossi; Roberta Oberti; David C. Smith Abstract The crystal structure of lisetite CaNa 2 Al 4 Si 4 O 16 , a = 8.260, b = 17.086, c = 9.654 Å, space group Pbc2 1 Z = 4, has been determined through direct methods using 1445 intensities measured with an automated X-ray diffractometer...

... of –UDUD– rings. The complete Ba 1− x Sr x Na 2 Al 4 Si 4 O 16 solid solution and very limited solid solution with lisetite, CaNa 2 Al 4 Si 4 O 16 , result from the topological similarity of the structures of banalsite and stronalsite, and significant differences with that of lisetite with respect...

...; it commonly overgrows lisetite and is associated with albitic plagioclase and taramitic amphibole. This eclogite occurrence is noted for its bulk-rock compositions rich in (Na + Al) and poor in (K + Mg). The paucity in K prevented the growth of nepheline, and the paucity in Si in precursor jadeite led...

Fig. 2 A SEM back-scattered electron image showing, in the centre, an oblique lath of intimately associated davidsmithite (Dvs, darker, outermost) and lisetite (Lis, lighter, innermost). This feature is clearly shown by the elemental maps in colour: Dvs is richer in Na than Lis, whereas the Al
