“…"Glomospira" and Pseudospira by the type of wall, larger size, the proportionally very thin wall that is often recrystallized, and the flexostyle canal of the proloculus. Olgaorlovella n. gen. differs from Pseudoagathammina sensu stricto by the more regular coiling and the absence of agathamminid stage; nevertheless, some Pseudoagathammina described by Lin et al (1990) and Filimonova (2010) probably correspond to our new genus. The flexostyle canal of the proloculus of Olgaorlovella davydovi n. gen. n. sp.…”

ВведениеПрошло более 150 лет со времени выделения пермской системы -единственного стратигра-фического подразделения такого высокого ранга Международной стратиграфической шкалы, уста-новленного на территории России [Мурчисон, 1841]. Изучение стратотипов всех ярусов этой сис-темы, установленных в разрезах Русской плат-формы и западного склона Урала, актуально и на УДК 551.736.1: 563.12: 470.57 значение фораминифер длЯ определениЯ Ярусных Границ пермской сисТемы международной сТраТиГрафической шкалы на примере разреза мечеТлино Abstract. The results of the study of distribution of foraminifers in the Mechetlino section, a potential candidate for the stratotype of the lower boundary of the Kungurian stage of the Cisuralian Series (Lower Permian) are presented. 20 samples were selected in 2015-2016 years. Specific complexes of fusulinides and smaller foraminifers were obtained at 17 levels of the section. Foraminifers were found only on three levels before these studies. The most representative complex of fusulinides is determined from the lower part of the section in layers 3-6. This assemblage is characteristic for the Sargian horizon of the Urals. The morphologically similar group of Pseudofusulina urasbajevi and Uralofusulinella arkaulensis group are located in this interval of the section. The single shells of fusulinides or fragment of shells are found in the layers 8, 10, 14 and 15. Smaller foraminifers are found on 17 levels and are represented by 59 species of 22 genera. The first foraminiferal complex belong to the Sargian horizon, the second - to the Saranian, the third has a more general Kungurian image. Markers of the Saranian horizon of the Kungurian among smaller foraminifers are determined above the assumed boundary. It is shown that the stratigraphic potential of foraminifers makes it possible to use this group of microfauna for a detailed subdivision of the Mechetlino section and interregional correlation of deposits.

The latest Carboniferous–Early Permian Dorud Group of the eastern Alborz (Iran): biostratigraphy and taxonomy of smaller foraminifers

et al. 2012

View full text Add to dashboard Cite

The latest Carboniferous–Early Permian Dorud Group in the Chaman‐Saver area of eastern Alborz, Iran is more than 222 m thick and includes thick sequences of oncolitic limestone, sandy limestone, sandstones and shales. The Emarat and Ghosnavi formations of this Group are dated here as latest Gzhelian to early Sakmarian Stages. During the Asselian Stage, the sea level fell abruptly and epeirogenic episodes occurred. These events generated a broad, shallow carbonate platform suitable for the growth and diversity of smaller foraminifers in the Chaman‐Saver area which, consequently, displays faunal differences with the rest of the Alborz Mountains. Three foraminiferal biozones are proposed: Nodosinelloides potievskayae–Vervilleina bradyi Zone (latest Gzhelian), Calcitornella heathi–Nodosinelloides sp. Zone (latest Gzhelian–Asselian), and Rectogordius iranicus n. gen. n. sp.–Hemigordius schlumbergeri Zone (early Sakmarian). The new taxa described herein include: Pseudovidalina iranica n. sp., P. damghanica n. sp., Rectogordius iranicus n. gen. n. sp. and Tezaquina sp. 1. Copyright © 2012 John Wiley & Sons, Ltd.
