| contents | Cores from Leg 122, Sites 759, 760, 761, and 764, were sampled at intervals of one sample per 1.5-m section in the Upper Triassic sequences. Spores, pollen, acritarchs, freshwater algae, and dinoflagellate cysts were studied to establish a palynostratigraphic framework for the Late Triassic. The palynological sequence is interpreted in terms of Australian spore-pollen zones: the Carman Samaropollenites speciosus Zone, the Norian Minutosaccus crenulatus Zone, and the Rhaetian Ashmoripollis reducta Zone. The Samaropollenites speciosus Zone-Minutosaccus crenulatus Zone boundary is marked by the change of pollen abundance and has a gradual character. Therefore, a transitional uppermost Carnian to Norian Samaropollenites speciosus/Minutosaccus crenulatus Zone is used. Age-determining dinoflagellate cysts are present in the Norian and Rhaetian sediments. |
