Geochemical, textural, mineralogical and micropaleontological data used for climatic reconstruction during the Holocene in the Galician sector of the Iberian continental margin

Geochemical, textural, mineralogical and micropaleontological data used for climatic reconstruction during the Holocene in the Galician sector of the Iberian continental margin

In the present study, Al, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb and Cd concentrations were determined in the sediments of the KSGX 40 core collected from the Galicia muddy patch (NW Iberian continental shelf). The results were integrated together with textural, mineralogical and micropaleontologica...

The results were integrated together with textural, mineralogical and micropaleontological (foraminifera) data in order to determine the possible climatic influence on the type of sedimentation that took place in the muddy patch. The geochemical data of the KSGX 40 core suggest that sediment composition and texture were significantly influenced, over the last 5.2 kyr, by the Holocene sea transgression and by climatic oscillations consisting of both relatively temperate/cold periods and relatively warm/wet periods. En el presente estudio se han determinado las concentraciones de Al, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb y Cd en un sondeo de sedimento recogido en el depósito lodoso de Galicia (NW de la plataforma continental ibérica). Estos resultados se han comparado con datos texturales mineralógicos y micropaleontológicos (foraminíferos) para estudiar la influencia climática en la sedimentación de este depósito lodoso. Los datos geoquímicos del sondeo KSGX 40 sugieren que la composición de los sedimentos y su tamaño de grano han estado influenciados durante los últimos 5.2 ka por la transgresión holocénica del nivel del mar y por oscilaciones climáticas que consisten tanto de periodos relativamente templados/fríos como de periodos cálidos/ lluviosos.
