Resumen
Accurate analysis of orientations of linear elements from polyphase populations involves computing statistics (mean, standard deviation) of each sub-population, which needs previous identification of the polymodal character and separation of sub-samples. The procedure here proposed for a regional study involves: (a) distinguishing polyphase from monophase samples; (b) characterizing mean and deviation of clearly monophase populations; (c) separating poliphase samples into sub-samples using density diagrams in equal-area projection and standard deviation values; (d) applying a correspondence test based upon the 95% confidence cone, as well as an equality F-test for directional samples, by comparison with monophase reference samples. An example of application of this procedure to pressure-solution lineations in carbonate pebbles of the Aliaga Tertiary basin (Teruel, Iberian Chain) is shown.
