Palynostratigraphy and palynofacies analyses are applied to identify transgressive-regressive sequences changes in paleoenvironment through the Middle Jurassic–Early Cretaceous succession of Ramså Basin on Andøya. The conglomerate, succeeding lacustrine-swamp deposits Hestberget Kullgrøfta members (Ramså Formation) overlying terrestrial marginal marine lower Bonteigen Member Formation), compris...

Abstract The Yola Sub-basin represents the lower portion of bifurcated Upper Benue Trough, whose origin has been linked to opening Atlantic Ocean in Mesozoic. sub-basin fill consists predominantly siliciclastic and carbonate deposits, ages which have remained controversial until now. This work employs field observations integrated with palynostratigraphy refine stratigraphy these Cretaceous dep...

Palynological investigations have been carried out on samples from the Upper Devonian Hongguleleng Formation of Western Junggar, Xinjiang, NW China. In total, 26 miospore species belonging to 19 genera and 28 acritarch assigned recognized lower member Fm. in Bulongguoer section. The palynofloral assemblages, particular taxa, are similar those eastern European early Famennian Corbulispora vimine...
