THE LANDANA SECTION (CABINDA, ANGOLA): A NEW REFERENCE PALEOCENE – EOCENE DINOFLAGELLATE CYST RECORD FOR EQUATORIAL REGIONS?
Forty-four of the rock samples from Dartevelle's Landana collection were palynologically processed and analysed using the standard maceration techniques as described by Jansonius and McGregor (1996). Dinoflagellates cysts recovered from the samples span the lower Paleocene to the lower Eocene and provide a new dinoflagellate stratigraphic record for the Paleocene - Eocene period in equatorial regions as well as providing constraints on the local palaeoenvironmental changes during that time. Dinoflagellate cyst occurrences were calibrated against foraminiferal (Lys et al., 1979) and carbon isotopic data allowing comparison and correlation against local and global records. Combination of quantitative and qualitative dinoflagellate cyst occurrences will contribute to the reconstruction of the Cenozoic depositional history of the westernmost (coastal marine) part of the Congo Basin.
