Magnetic susceptibility and CaCO3 content from Arroyo Gilico and Barranco de Cavila sections (Barremian, Early Cretaceous; Subbetic Domain, Southeast Spain)


The data of two sections studied in the Barremian (Early Cretaceous) of the Subbetic Domain (SE Spain) are shown here together with a detailed log showing the bed number and the biostratigraphic scheme. The samples were collected with a geologist hammer in May 2016. The average sample distance is 0.07 m and was kept as constant as possible using a Jacob's staff to ensure the detection of all the Milankovitch cycles applying Fast Fourier Transforms and related methods (e.g. multi-taper). The lithology is composed of marl-limestone alternations deposited in a (hemi-)pelagic setting. Observed fauna is composed of ammonites, radiolarians, foraminifera, calcareous nannofossils and scarce belemnites, bivalves, gastropods, brachiopods and irregular echinoids. The biostratigraphy scheme is provided in the detailed logs and is based on Tethyan ammonite and calcareous nannofossils. The two sections studied are Arroyo Gilico section (38°9'35'' N; 1°40'41'' W; the interval studied covers from the Late Hauterivian (Balearis Zone) to the Late Barremian (Vandenheckii Zone)) and Barranco de Cavila section (38°3'10'' N; 1°53'20'' W; the interval studied covers from the Late Barremian (Vandenheckii Zone) to the Early Aptian (Forbesi Zone)).Magnetic susceptibility was measured with a KLY-3 and calcium carbonate content was measured following the volumetric method using the automatic calcimeter Dream Electronique
