Resum
The existing problems in the analysis of tectonical evolutions by brittle indicators in areas affected by several phases, as well as the populational analysis methods based on the concepts of eigenvalues and eigenvectors are analyzed, concluding that it is preferable to use methods in which the singularity of each data is not lost, as in the P /T and y /R diagrams. The «slip model» is developed, introducing the K' factor (ey/ez ratio in the strain ellipsoid) and drawing the e/K' and e/0 diagrams, from which it is possible to analyze the evolutions of type of the strain ellipsoid just from trends and clips of faults. To study brittle tectonics in a given area it is proposed the use of a combination of methods, and to take into account the data obtained by field geology.
