Palaeonitella trifurcata n. sp. is a minute ecorticate thallus of charophyte from non-marine upper Barremian–Lower Aptian section the Garraf Massif, near Barcelona (Catalonia, Spain). Whorls trifurcated branchlets built glomerules about 1 mm across. Small radial were once in three terminal acuminate dactyls. Longer and more robust branches, two per whorl emerge basal trifurcation, bore opposite...

The Hauterivian–Aptian Isachsen Formation at Glacier Fiord, Axel Heiberg Island, in the Sverdrup Basin of Canadian Arctic Archipelago was deposited contemporaneous with initiation High Large Igneous Province (HALIP). New palynological biostratigraphy and paleoenvironmental reconstruction, coordination emerging geochronology HALIP igneous rocks, permits exploration effects volcanism on vegetatio...

tirgan formation with lower cretaceous age (barremian-aptian) in the kopet-dagh basin consists of carbonate and siliciclastic rocks (calcareous shale and sandstone) which conformably lay between siliciclastic rocks of shurijeh formation below, and marly sarcheshmeh formation at the top. in this study, tirgan formation in two stratigraphic sections of abgarm (77 m in thickness) and sirzar (46 m ...

We investigate the present-day orogenic architecture of Pyrenean-Cantabrian junction corresponding to a boundary between inverted rift segments using seismic interpretation, field data, and borehole information. This was formerly attributed major NNE-SSW striking Pamplona transfer fault segmenting Basque-Cantabrian Mauléon basins during both rifting convergence. Our study shows that results fro...

The present study concerns the elimination by retention of anionic dye orange II (OII) from aqueous solutions was studied using a silica gel prepared Tunisian sands (Barremian age). These Sidi Aich were collected in central Tunisia. raw sand Jebel Meloussi (central Tunisia) characterised different techniques, such as X-ray diffraction (XRD), fluorescence (XRF) and scanning electron microscopy (...
