摘要

在这里，我们对伊朗扎黑丹北部Hormak剖面的Alveolina组合进行了详细的分类学研究。Alveolina标本是从一个16米厚的浅水始新世序列中发现的，该序列在有限的范围内出现。已鉴定出16个物种，包括Alveolina cf.oblonga、A.ruetimeyeri、A.minuta、A.cf.cosegena、A.sp.cf.Swageri、A.sp.aff。A.azzarolii、A.haymanaensis、A.canavari、A.canawari karsakensis、A.coudurensis、A.histrica histrica、A.bayburtensis、A.cf.azzaroli、A.stercusmuris、A.kieli和A.elliptica nuttali。Alveolina种的记录范围从SBZ10（早期Cuisian）到SBZ13（早期Lutetian）。这项系统研究为锡斯坦洋带（特提斯中部地区）的古生物地理分布提供了新的见解，并可能为未来对邻近特提斯地区的研究做出预测。

Upper Ypresian to Lower Lutetian (SBZ 10 to 13) Alveolina stratigraphic horizons from the Hormak section, Zahedan District, Sistan Suture Zone, Eastern Iran

Here we present a detailed taxonomic study of Alveolina assemblages from the Hormak section, northern Zahedan, Iran. The Alveolina specimens have been recovered from a 16 meters thick shallow-water Eocene succession cropping out in an area of limited extent. Sixteen species have been identified including Alveolina cf. oblonga, A. ruetimeyeri, A. minuta, A. cf. cosigena, A. sp. cf. A. schwageri, A. sp. aff. A. azzarolii, A. haymanaensis, A. canavarii, A. canavarii karsakensis, A. coudurensis, A. histrica histrica, A. bayburtensis, A. cf. azzarolii, A. stercusmuris, A. kieli and A. elliptica nuttalli. The record of Alveolina species spans from SBZ10 (early Cuisian) to SBZ13 (early Lutetian). The systematic study provides new insight on the paleobiogeographic dispersal among the Sistan Ocean zone (central Tethys region) and may permit to make projections for future studies on neighboring Tethyan regions.

期刊介绍： The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny. Owned by The Micropalaeontological Society, the scope of the journal is broad, demonstrating the application of microfossils to solving broad geoscience issues.
