Bfocvec | R Documentation |
Calculates Angles for determining ternary distribution of faults based on P-T axis orientation.
Bfocvec(Paz, Pdip, Taz, Tdip)
Paz |
vector of azimuths, degrees |
Pdip |
vector of dips, degrees |
Taz |
vector of azimuths, degrees |
Tdip |
vector of dips, degrees |
This calculation is based on Froelich's paper.
LIST:
Bdip |
