The end-member modelling approach lets to decompose multimodal grain-size distribution into genetically meaningful subpopulation that may be related to different sediment transport mechanisms and source areas. Three end-members have been identified in the contourite drift and moat system located at the southern side of the Dijbouti Ville seamount that have been interpreted in terms of sediment sources. Two end-members point to an eolian source and comprise fine silt (EM1) and coarse silt (EM2) as modal grain-sizes, characterized by high and low contents, respectively, of terrigenous elements (Al, Si, Ti and K). The third end-member (EM3) indicates a fluvial origin and is mainly defined by a clay modal grain-size of intermediate and homogeneous content in terrigenous elements. Downcore variation of the relative proportion of these EMs can be used to decipher paleocenographic and paleoclimatic conditions in the Alboran Sea This research has been supported by MONTERA (CTM2009-14157-C02) and MOWER (CTM2012-39599-C03) projects of the MINECO Peer Reviewed 2015 2016-04-25T08:16:11Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 Volumen de comunicaciones presentadas en el VIII Simposio sobre el Margen Ibérico Atlántico: 571-574 (2015) http://hdl.handle.net/10261/131376 http://dx.doi.org/10.13039/501100003329 Sí none Centro Oceanográfico de Málaga |
