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 shownspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Pressure-solutionLineationStatisticsPoliphase samplejournal articleopen access
