...G. Y. CHAO Abstract Carletonite, a new mineral from Mont St. Hilaire, Quebec, is tetragonal P4/mbm , with a = 13.178 Å, c = 16.695 Å, and z = 4. The structure was solved by threedimensional Patterson synthesis and refined by full-matrix least-squares method using anisotropic temperature parameters...

...G. Y. Chao Abstract Carletonite, KNa 4 Ca 4 Si 8 O 18 (CO 3 )·(F,OH)·H 2 O, occurs in thermally metamorphosed inclusions in the nepheline syenite at Mount St. Hilaire, Quebec. It is associated mainly with pectolite. albite, arfvedsonite, calcite, fluorite, and apophyllite. The mineral is tetragonal...

.... , 2019 ). The first description of this mineral was provided by Kaneva et al . ( 2020a ), who also explained the difference with respect to the structural analogue carletonite, KNa 4 Ca 4 Si 8 O 18 (CO 3 ) 4 (OH,F)⋅H 2 O (Kaneva et al ., 2023 ). The latter is a rare mineral named after Carleton...
