Resumo
Computed tomography (CT scan) is a non-destructive technique of sedimentary analysis rarely used in oceanic cores. This technique allows a simple way to obtain radio-density measurements of high quality, very high resolution and detail. Its application allows obtaining an accurate image of the sedimentary changes recorded and the correlation between the cores without prior manipulation, saving time and analytical costs. The large amount of data obtained by a CT-scan, requires the use of programs or tools to envisage their analysis, understanding and meaning. With this objective the "anidoC" program was developer to allow the identification of certain events with a very characteristic radiodensity signal recorded in the Pleistocene sedimentary infill of the Galicia Interior Basin. The anidoC allows the discrimination of Heinrich Events signal and to limit the intervals in which they are recorded. To validate this program its results have been compared with those obtained by conventional techniques in five cores. Validation and implementation can be extended to other cores of the region in order to understand more quickly and accurately their sedimentary infill and the chronostratigraphy of the Upper Pleistocene
