摘要

本研究首次对伊朗东部图塔克剖面上白垩统 Maastrichtian 的底栖有孔虫进行了研究。在图塔克剖面，蛇绿岩单元之间出露了零星透镜状的马斯特里赫特碳酸盐沉积物。在该区段发现的底栖有孔虫有：Orbitoides apiculatus、Orbitoides medius、Omphalocyclus cf. macroporus、Orbitoides cf. gruenbachensis、Orbitoides gensacicus、Orbitoides spp.、Sirelina orduensis、Canalispina iapygia、Goupillaudina spp.、Selimina spinalis、Postomphalocyclus merici。由于在伊朗东部没有对这种底栖有孔虫进行全面的研究，作者建议将伊朗东部 Flysch 盆地的这些马斯特里赫特沉积物命名为 Makhunik 单元。

First report of the benthic foraminifera from Maastrichtian in the Eastern of Iran (Tutak section)

In this research, benthic foraminifera from the Upper Cretaceous Maastrichtian in the Tutak section (Eastern Iran) was studied for the first time. In the Tutak section, there are outcrops of scattered and lenticular Maastrichtian carbonate sediments between the ophiolitic units. Some of the benthic foraminifera identified in this section are Orbitoides apiculatus, Orbitoides medius, Omphalocyclus cf. macroporus, Orbitoides cf. gruenbachensis, Orbitoides gensacicus, Orbitoides spp., Sirelina orduensis, Canalispina iapygia, Goupillaudina spp., Selimina spinalis, Postomphalocyclus merici. Since there is no comprehensive study of this benthic foraminifera in eastern Iran, the authors suggest the name of the Makhunik unit for these Maastrichtian sediments in the Flysch Basin in the eastern part of Iran.
