Formula:

Na7(Al6-xSi6+xO24)(C2O4)0.5+x · 5H2O (0 < x < 0.5)

Colour:

Pale bluish, bright blue, greenish-blue, grayish-blue or colorless

Name:

Name reflects the mineral's blue colour and the presence of oxalate.

Cancrinite group

Two kyanoxalite varieties are distinguished:
(1) with predominantly acid oxalate groups and
