The 95 rhythms studied represent ~1180 ka and correspond to ~20cm/20ka. The limestone layers are thicker than marls and the Fischer diagram detects several shifts of high sedimentation and some well-marked minimums. The high-resolution of the twelve limestone layers (<1cm/analysis; 317 analysis, 3.06 m) shows complex curves indicative of climatic fluctuations. The pink-white colour variations are indicative of accidental oxygenated water masses presence, without diagenesis influencespaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/CyclostratigraphyMarl/limestone coupletsAutomatic calcimeterDanesjournal articleopen access
