Lithostratigraphy and carbonate microfacies across the Permian-Triassic boundary near Julfa (NW Iran) and Abadeh (Central Iran)
Permian-Triassic boundary sections in the regions of Julfa (NW Iran) and Abadeh (Central Iran) display three characteristic rock units: (1) the Paratirolites Limestone (4-5 m thick) with the mass extinction horizon (P-Tr ...
Morphological evolution and extinction patterns of the Ammonoidea at the Permian-Triassic boundary of Iran
The classical Permian-Triassic (P-Tr) boundary sections in the vicinity of Julfa (NW Iran) and in the Baghuk Mountain area (Central Iran) have high potential for the study of the end-Palaeozoic extinction event. The ...
Early Triassic microbialites and carbonate factory changes across the Permian-Triassic boundary near Julfa (NW Iran) and Abadeh (Central Iran)
Permian-Triassic boundary sections in the regions of Julfa (NW Iran) and Abadeh (Central Iran) display three characteristic rock units: (1) the Paratirolites Limestone (4-5 m thick) with the mass extinction horizon (P-Tr ...
Sporadoceratid ammonoids from the Shotori Range -east-central Iran- – a case of putative gigantism caused by hydraulic sorting?
The Shotori Range of east-central Iran -east of Tabas- has yielded Famennian ammonoid assemblages dominated by the family Sporadoceratidae. Four genera Maeneceras Hyatt, 1884, Iranoceras Walliser, 1966, Sporadoceras Hyatt, ...
Lithostratigraphy and carbonate microfacies across the Permian–Triassic boundary near Julfa (NW Iran) and in the Baghuk Mountains (Central Iran)
Permian–Triassic boundary sections in the Julfa (NW Iran) and Abadeh (Central Iran) regions display
a succession of three characteristic rock units, (1) the Paratirolites Limestone with the mass extinction horizon ...
Pre–mass extinction decline of latest Permian ammonoids
The devastating end-Permian mass extinction is widely considered to have been caused by large-scale and rapid greenhouse gas release by Siberian magmatism. Although the proximate extinction mechanisms are disputed, there ...
