Permian Stratigraphy and Fusulinida of Afghanistan With Their Paleogeographic and Paleotectonic Implications

Permian rocks are widespread in Afghanistan and species of the Fusulinida show that all stages of this system from Asselian to Dorashamian are present. All of the species encountered in this study from almost all known Permian exposures in Afghanistan are herein described and figured, including one new genus, Laosella n. gen., and 41 new species and subspecies including Neofusulinella callosa n. sp., N. magna n. sp., Codonofusiella simplex n. sp., Biwaella tumefacta n. sp., Zellia heritschi afghanica n. subsp., Rugososchwagerina altimurica n. sp., R. heratica n. sp., Darvasella ponderosa n. sp., D. cucumeriformis n. sp., Dutkevitchia sourkhobensis n. sp., Darvasites ordinatus longus n. subsp., D. afghanensis n. sp., Chalaroschwagerina bamianica n. sp., C. sourkhobensis n. sp., Pseudofusulina karapetovi n. sp., P. karapetovi gudriensis n. sp. and n. subsp., P. karapetovi tezakensis n. sp. and n. subsp., P. macilenta n. sp., P. peregrina n. sp., P. fabra grandiuscula n. subsp., P. acuminatula n. sp., P. hessensis orientalis n. subsp., P. heratica n. sp., P. sourkhobensis n. sp., P. priva n. sp., P. bulolensis n. sp., P. argandabensis n. sp., P. immensa n. sp., P. perspicua n. sp., P. haftkalensis n. sp., Praeskinnerella crassitectoria afghanensis n.subsp., Parafusulina uruzganensis n. sp., Chusenella subextensa n. sp., Rugosochusenella dialis n. sp., Verbeekina (Quasiverbeekina) altimurensis n. sp., Cancellina (Shengella) bamianica n. sp., Neoschwagerina bamianica n. sp., Colania altimurensis n. sp., Presumatrina uruzganensis n. sp., P. longa n. sp., and Sumatrina bulolensis n. sp.The current study shows that the fusulinid faunas in Afghanistan and adjacent Pamir can be used to compare and contrast the different tectonic zones present in these two regions. Four major conclusions regarding the geologic history of Afghanistan and surrounding territories follow:1. The geology of Afghanistan and Pamir is complex, and the Permian rocks in the numerous tectonic zones are small relics of much larger depositional basins that were crushed during the collision of the Indostanian and Laurasian plates. The carbonate facies and fusulinid assemblages of the Asselian and Sakmarian Stages in north Afghanistan and north Pamir, which apparently had marine connections with south Tien Shan and the southern Ural region, are characteristic of tropical shelves. Asselian and lower Sakmarian(?) rocks of south Afghanistan and southPamir, however, are exclusively siliciclastic, lack fusulinids, but contain cold-water bryozoans, brachiopods, and bivalves typical of Perigondwanan seas. A fusulinid fauna that is endemic and quite different from coeval faunas in the northern areas appears only in the upper half of the Sakmarian Stage. This fusulinid assemblage suggests that the Lower Permian rocks in south Afghanistan were formed in cool-to moderately cold-water environments. Because the northern and southern areas of Afghanistan and Pamir that once were in different climatic belts are now essentially Downloaded from 2 E. Ja. Leven in contact, t...

“…They are especially abundant in the Central Mountains where they develop reef constructions signalled by Boutière and Brice (1966) in the Chaghana-Oudjerak section, term 4 (Frasnian); by Jux (1969) in the Caraghsang section, in ferrugineous pseudoolithic limestone (=''Hajigak-Erze'') (Frasnian); by Plodowski (1970), and Wolfart and Wittekindt (1980) with Fistulipora cyclostoma, in southwest of Dasht-e Nawar (Upper Devonian); by Blaise et al (1971) in the Makhtum section (Frasnian); by Brice and Mistiaen (1980) in the Dewal section, bryozoan reef, (Frasnian); by Blieck et al (1982) in the Koh-e Top, Koh-e Qutun, Saïd Habib and Ghoujerak sections, Fistuliporid bryozoans often associated with Receptaculites (Frasnian); by Mistiaen (1980Mistiaen ( , 1985 in twenty-nine sections around Dasht-e Nawar (Table 6) (Upper Devonian).

“…Boutière and Brice (1966) noted the presence of Receptaculites just below ferruginous red beds with oolitic limestone, in the Chaghana-Oudjerak section. Blaise et al (1971) also stressed the presence of Receptaculites in the Makhtum section and discussed the presence of Receptaculites neptuni in the Spina Kada section (associated with bryozoans in reefal limestone). Brice (1971) compared the ''red limestone with crinoids, ferruginous oolites and Receptaculites'' of Upper Devonian in the Dascht-e Nawar (Kutun and Badragha sections) with similar beds in Iran where Receptaculites is associated with goniatites and is probably Famennian in age.…”
