Saccani {GCDkit} | R Documentation |
Assigns data for Saccani's diagram into Figaro template (list 'sheet
') and
appropriate values into 'x.data
' and 'y.data
', the latter also into
the matrix 'results
'.

The diagram of Saccani (2015), based on NMORB-normalized Nb[N]-Th[N] values (Sun and McDonough 1989), serves for discrimination of geotectonic setting of basalts. The individual fields are illustrated on the original figures of Saccani's work:
