Foraminiferal morphogroups in dysoxic shelf deposits from the Jurassic of Spitsbergen

Brachiopods from Late Jurassic-Early Cretaceous hydrocarbon seep deposits, central Spitsbergen, Svalbard.

Late Jurassic-Early Cretaceous (Late Volgian-latest Ryazanian) rhynchonellate brachiopods are described from eight out of 15 hydrocarbon seep deposits in the Slottsmøya Member of the Agardhfjellet Formation in the Janusfjellet to Knorringfjellet area, central Spitsbergen, Svalbard. The fauna comprises rhynchonellides, terebratulides (terebratuloids and loboidothyridoids) and a terebratellidine....

Distribution and Paleoecology of the Middle Jurassic Foraminifera from Eastern Alborz (Goznawwi section)

Analysis of benthic foraminiferal assemblages was performed in Callovian deposits of the Farsian Formation Northeastern Alborz; Iran. The sequence of Callovian at the Goznawwi area consists mainly of soft marls , which contain high-diversity calcareous assemblages. In this foraminiferal succession nine morphogroups were differentiated according to shell architecture (general shape, mode of coil...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Methane seeps on an Early Jurassic dysoxic seafloor

Foraminiferal biozonation and morphogroups from shale memberof the Aitamir Formation in Maraveh Tappeh section, northwest Koppeh-Dagh Basin

AbstractThe Aitamir Formation is divided into two members the lower sandstone and the upper shale. 32 genera and 57 species of foraminifera have been recognized. According to identified foraminifera Rotalipora appenninica Interval Zone, Rotalipora globotruncanoides (Rotalipora brotzeni) interval zone and Whiteinella aumalensis-Dicarinella canaliculata assemblage zone are proposed and a l Albian...
