Note: * Type sample of cordylite from Narssarssuk, Greenland.
1 Analyzed by Vienna group.
2 Analyzed by Miami group.
Numbers in parentheses denote the standard deviation.
For atoms Ba, Ce, Na, F, C1 and C2: U1,1 = U2,2, U1,2 = 0.5 x U1,1, U1,3 = U2,3 = 0;
for atoms O1 and O2: U1,2 = 0.5 x U2,2, U2,3 = 2 x U1,3.
