DebonQB {GCDkit} | R Documentation |
Assigns data for Debon & Le Fort's Q vs. B diagram into Figaro template (list 'sheet
') and
appropriate values into 'x.data
' and 'y.data
'.
DebonQB()
The Q vs. B diagram was proposed by Debon and Le Fort (1983) for aluminous associations. It defines three associations, reflecting maficity of samples: leucocratic, subleucocratic and mesocratic.
Parameters for the diagram are calculated by the function 'DebonCalc
'.
All of them are based on millications (1000 gram-atoms per 100 grams).
Q = Si / 3 - (K + Na + 2 * Ca / 3) [cationic proportion of quartz]
B = Fe + Mg + Ti [maficity]
For details, see Debon & Le Fort (1983) and (1988).
