the nayband formation was measured and sampled in parvadeh area, southern tabas city. in this area, this formation has a thickness of 1410 m, dividing into four members, namely gelkan, bidestan, howz-e-sheikh and howz-e-khan. a total 573 samples were treated for palynological analysis, and only 120 samples were productive. a total of 57 miospore taxa and 11 plant macrofossil were encountered. b...

Analyses of marine and terrestrial palynomorphs Ocean Drilling Program (ODP) Site 645 in Baffin Bay led us to define a new biostratigraphical scheme covering the late Miocene Pleistocene based on dinocyst acritarch assemblages. Four biozones were defined. The first one, from 438.6 m below sea floor (mbsf) 388 mbsf, can be assigned early Pliocene age (>4.5 Ma), common occurrence Cristadinium ...

red beds, conglomerates and salt were considered azoic and problematic rocks, but paleopalynology and inorganic geochemistry proved to be useful for placing them in time and space. in the early last century, in mexican ne region, only three mesozoic red bed units were differentiated, dated as late triassic to late jurassic. it was important tratigraphically to place them properly as they were c...
