Wood {GCDkit} | R Documentation |
Assigns Figaro templates to Wood's geotectonic diagrams for basaltoids
into the list 'plate
' and appropriate values into
the list 'plate.data
' for subsequent plotting.

A series of triangular diagrams with apices Th-Hf/3-Ta, Th-Hf/3-Ta and Th-Zr/117-Nb/16, proposed by Wood (1980).
Following fields are defined:
IAT | Island-arc Tholeiites |
CAB | Calc-alkaline Basalts |
N-MORB | N-type Mid-ocean Ridge Basalts |
E-MORB | E-type Mid-ocean Ridge Basalts |
WPT | Within-plate Tholeiites |
WPA | Alkaline Within-plate Basalts |

list with Figaro Style Sheet data |
x.data, y.data |
Th, Hf/3 and Ta in ppm recalculated into two dimensions |
This function uses the plates concept. The individual plots can be selected and their
properties/appearance changed as if they were stand alone Figaro-compatible plots.
