Palynological Study of Carbonated Mounds during the Holocene along the Atlantic and Mediterranean Moroccan Margins

摘要: Abstract A palynological study of carbonate mounds Atlantic and Mediterranean Moroccan margins was conducted on sediment boxcores MD13-3441, MD13-3456, MD13-3461, MD13-3465, MD13-3468 collected during the oceanographic cruise MD 194/Eurofleet - GATEWAY, which took place June 2013. The organic remaining revealed a dominance dinoflagellate cysts over continental fraction, showed very low rates. use pollen data, despite their representativity, is proving to be valuable tool for paleoclimate interpretation. quantitative qualitative analysis evolution paleoenvironment climate change this interval. terminal Pleistocene–basal Holocene passage highlighted by cold taxa cysts. presence tree shrub coupled altitudinal conifers confirmed in both marine environments. During lower-middle Holocene, variations relative frequencies cyst associations reflect from inner neritic oceanic. recorded microflora shows cyclicity lower arid semi-arid between 10.07 9.85 ka (the abundance herbaceous steppe), become again around (9.69 ka) consistently high rate steppe. In contrast, Middle semi-humid 6.29 ka (high trees shrubs) evolves warm dry at 5.9–5.14 ka, reflected
