Bolorian and Kubergandian stages of the Permian in the Sanandaj-Sirjan zone of Iran     

E. Ja. Leven  M. N. Gorgij 《Stratigraphy and Geological Correlation》2008,16(5):455-466

Sections and fusulinids of the Bolorian (presumably) and Kubergandian (lower part) stages in the Sanandaj-Sirjan tectonic zone are described. Two fusulinid assemblages are distinguished in a most complete section near Sirjan. The lower one is represented by Skinnerella, Paraleeina, and relatively primitive Misellina forms, whereas Armenina, Kubergandella, and Yangchienia species appear in the upper assemblage and suggest its early Kubergandian age. Accordingly, the lower assemblage is attributed to the Bolorian Stage, although it is lacking fusulinids typical of this stage except for the primitive Misellina morphotypes. Fusulinids from the Tange-Darchaleh section near Qomsheh (Shahreza) are typical of the Kubergandian Stage. The described three new species of the genus Skinnerella are close to morphotypes known from younger (Murgabian) deposits and represent their ancestral forms most likely.  相似文献   

First finds of Permian conodonts in eastern Iran and once again on the Guadalupian series base in Permian sections of the Tethyan realm

Conodonts found for the first time in eastern Iran (the Bage-Vang section) are characterized. Beds with conodonts also yield fusulinids that is suitable for refining correlation of conodont and fusulinid zonations. Stratigraphic ranges of different conodont species in the Bage-Vang section are correlated with those in the Luodian section (South China), where conodonts are also accompanied by fusulinids. As a result, some previous inferences concerning position of the Guadalupian Series base in the Tethyan sections are refined.  相似文献
