DebonKNaB {GCDkit} | R Documentation |
Assigns data for Debon & Le Fort's K/(Na+K) vs. B diagram into Figaro template (list 'sheet
') and
appropriate values into 'x.data
' and 'y.data
'.
DebonKNaB()
The K/(Na+K) vs. B diagram was proposed by Debon and Le Fort (1988) for aluminous magmatic suites. It defines three associations based on the balance of the two alkalis, namely potassic, sodi-potassic and sodic (note that the x axis is reversed). Moreover, leucocratic, subleucocratic and mesocratic associations are distinguished based on maficity of the samples.
Parameters for the diagram are calculated by the function 'DebonCalc
'.
All of them are based on millications (1000 gram-atoms per 100 grams).
K/(Na + K) [alkali ratio]
B = Fe + Mg + Ti [maficity]
For details, see Debon & Le Fort (1983) or (1988).
