Preliminary results of palynological investigations of Triassic strata in North Vietnam
Bui Duc Thang
Assemblages of miospores and pollen grains found in the upper part of the Suoi Bang Formation in North Vietnam comprise 43 taxa, including two new combinations: Deltoidospora concava (Bolkovitina) comb. nov. and Polypodtites polymicroforatus (Orłowska-Zwolińska) comb. nov. The assemblages from Vietnam largely resemble those from Europe, Iran and Afghanistan; this analogy permitted dating the upper part of the Suoi Bang Formation at the Rhaetian-Lias.
Key words: Miospores, pollen, Upper Triassic, north-west Vietnam.
