Resumen de Un protocolo de tratamiento estadístico para muestras polifásicas de lineaciones de disolución
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.
