DOIAbstract
A total of 24 sediment samples with wide dimensional, mineralogical and compositional range were considered, collected from 5 Italian coastal marine sites. The fine fraction (<63 μm) was analyzed using Laser Granulometer (LG) and X-ray Sedigraph (XS) in order to compare data and highlight potential differences. The unexpected variable sandy fraction in nearly all the samples was attributed to clay mineral aggregates. The highest sand percentages detected by XS were attributed to local compositional sediment features. An increase of 15–25% of clay in samples analyzed by XS was attributed to the different working principles of the considered devices. Nevertheless, final results succeeded in characterizing sediment texture and distribution as ...
