...Sarah E.M. Palaich; Craig E. Manning; Edwin Schauble; Abby Kavner Abstract The rare evaporite minerals hanksite, Na 22 K(SO 4 ) 9 (CO 3 ) 2 Cl, and tychite, Na 6 Mg 2 (CO 3 ) 4 (SO 4 ), are excellent case studies for the high-pressure behavior of ionic groups since their structures combine ionic...

...Lewis S. Ramsdell Abstract The composition of 9Na 2 SO 4 • 2Na 2 CO 3 • KC1 for hanksite is verified. There are 2 formula weights in the hexagonal unit cell, which has a= 10.46Å and c = 21.18Å; c/a= 2.02. The space group is either C 6 6 —(C6 3 ) or C 6h 2 —(C6 3 /m), with the morphological evidence...

... column occurs in the crystal structure of hanksite, Na 20 (CO 3 ) 2 Cl[KNa 2 (SO 4 ) 9 ]. Hypotheses are advanced for growth of apatite, whose central argument is the inherent stability of the [Ca 4 (PO 4 ) 12 ] columns; disorder and calcium deficiencies in some apatites may arise from the rotational...
