UNLABELLED PREMISE OF THE STUDY Digital microscopic pollen images are being generated with increasing speed and volume, producing opportunities to develop new computational methods that increase the consistency and efficiency of pollen analysis and provide the palynological community a computational framework for information sharing and knowledge transfer. • METHODS Mathematical methods we...

The Moscovian plant macroflora at Cottage Grove southeastern Illinois, USA, is a key example of Pennsylvanian (323-299 Million years ago) dryland vegetation. There is currently no palynological data from the same stratigraphic horizons as the plant macrofossils, leaves and other vegetative and reproductive structures, at this locality. Consequently, reconstructions of the standing vegetation at...

The Paleozoic sediments of the Chal-i-Sheh area in southwestern Iran comprising of Mila Formation, Ilebek Formation and Faraghan Formation, were studied palynologically. The samples containing well-preserved palynomorphs include acritarchs, chitinozoans, scolecodonts and pollenlspores. A palynological zonation has been established and comparison was made with other parts of the world. Based...

Kelussia odoratissima Mozaff. is a sweet-smelling, self-growing plant which is traditionally consumed in Iran as a garnish. The aim of this project was study the structure of pollen grains in Kelussia odoratissima. Anthers of Kelussia were collected at full flowering stage from wild populations. Structure pollen grains were studied by scanning electron microscopy. The results showed that pollen...

Abstract. In the Late Devonian to earliest Mississippian, Svalbard was affected by a short-lived episode of deformation named Svalbardian Orogeny. This event resulted in intense folding and thrusting sedimentary successions. Deformation stopped prior deposition Carboniferous Permian strata Billefjorden Gipsdalen groups, which lie unconformably over folded strata. Later on, presumed structures w...
