摘要

本研究以伊朗西北部 Qamcheqai 段下中新世陆架碳酸盐岩中的大型底栖有孔虫为基础。在沉积时期，所调查的地区位于东特提斯和西特提斯之间的特提安海道欧亚大陆一侧。研究发现了 7 个多孔和透明穿孔物种，包括 Praebullalveolina curdica、Peneroplis evolutus、Androsina cf. diyarbakirensis、Sivasina egribucakensis、Miogypsina cf. intermedia、Operculina complanata 和 Amphistegina bohdanowiczi。Miogypsina cf. intermedia 和 Praebullalveolina curdica 的出现使该集合体与 SBZ 25 区相关联，表明其时代为伯迪加利亚时代。这项研究的结果将特有类群 Androsina 和 Sivasina 的古地理分布范围向东扩展至伊朗中部。

Foraminiferal distribution and biostratigraphy of the Lower Miocene Qom formation, north of Bijar, NW Iran

This study is based on larger benthic foraminifera that dominate the Lower Miocene shelf carbonates of the Qamcheqai section, NW Iran. During the time of deposition, the investigated area was positioned on the Eurasian side of the Tethyan Seaway between the Eastern and Western Tethys. Seven porcelaneous and hyaline perforated species were determined, including Praebullalveolina curdica, Peneroplis evolutus, Androsina cf. diyarbakirensis, Sivasina egribucakensis, Miogypsina cf. intermedia, Operculina complanata, and Amphistegina bohdanowiczi. The presence of Miogypsina cf. intermedia, and Praebullalveolina curdica allowed to correlate the assemblage with SBZ 25 Zone, indicating a Burdigalian age. The results of this study extend the paleogeographic distribution of the endemic taxa Androsina and Sivasina eastwards as far as Central Iran.

期刊介绍： La Revue de micropaléontologie publie 4 fois par an des articles de intérêt international, consacrés à tous les aspects de la micropaléontologie. Les textes, en anglais ou en français, sont des articles originaux, des résultats de recherche, des synthèses et mises au point, des comptes rendus de réunions scientifiques et des analyses de ouvrages. La revue se veut résolument ouverte à tous les aspects de la micropaléontologie en accueillant des travaux traitant de la systématique des microfossiles (et de leurs équivalents actuels), des bactéries aux microrestes de vertébrés, et de toutes leurs applications en sciences biologiques et géologiques.
