Abstract Calcareous nannofossils are < 30 µm sized calcitic fossil remains of single-celled marine photoautotrophic algae. Carbonate-rich sedimentary rocks, containing these fossils, used as raw material for lime-based mortars. The carbonates (CaCO 3 ) heated up to approx. 900 °C. burning process, which causes the thermal decomposition CaCO into CaO (= quicklime) and CO 2 , destroys fossils....

Paleoenvironmental reconstruction of the Mediterranean Basin at end Messinian Salinity Crisis is contentious. One section that records this final phase (Stage 3) Pollenzo Section in Piedmont (NW Italy). Here, we present new stratigraphic, sedimentological, petrographic, micropaleontological (ostracods, calcareous nannofossils, foraminifera, dinoflagellates) and geochemical (87Sr/86Sr ratios) da...

A Detailed Calcareous nannofossil study conducted on the Bekhme Formation that is cropped out at Southern limb of Bekhere anticline, eastern ward Dohuk city near Bajlur village, northern Iraq. The composed marly limestone, Organic limestone and fossiliferous limestone. nannopaleontological classification these calcareous nannofossils led us to determine thirty-four genus/species belonging nine ...
