International audience; A Cenomanian clay lens in Hucheloup Quarry (Maine-et-Loire, north-western France) has yielded 82 foliar compressions and impressions, of which 62 were identified at several taxonomic levels. The plants are ascribed to diverse Pinales (27%), ferns (27%), Ginkgoales (26%), angiosperms (19%) and Cycadales (1%). The most abundant species in the assemblage are Frenelopsis alata (K. Feistmantel) E. Knobloch emend. J. Kvaček (Pinales) and Eretmophyllum obtusum (Velenovský) J. Kvaček (syn. E. andegavense Pons, Bourreau et Broutin) (Ginkgoales). Wood fragments, along with very well-preserved cuticles, have also been recovered and identified. The specimens are usually very fra…

To describe the geochemical features of the sediments in nine sicilian coastal lakes, 78 samples of surface sediments were collected in July 2005. Analyses of Nitrogen, Total Organic Carbon, Organic Matter, Carbonates and Grainsize were performed. A better correlation between the Organic Matter, evaluated through the Sequential-LOI, and TOC was found at 350 °C, rather than at 450 °C. Statistical analysis confirmed the similarities of the trends of TOC and LOI350 in the samples pooled according to the dominant grainsize, with the highest values associated to the medium sand fraction. The differences among the median values of the groups were significant (ANOVA, Kruskal-Wallis; P<0.001). The …
