摘要

本研究的目的是从Bizeljsko组43米厚的剖面中识别介形虫组合，该组构成了上中新世Posavje群的中部。该层序包括沉积在三角洲前缘环境中的砂岩、粉砂岩和泥灰岩。已确定的介形虫属于Cyrididae、Cytheridae、Darwinulidae和Loxocancidae科。总共鉴定出30个物种。此外，在属水平上确定了8种形态类型。最常见的属是Candona属、Hemicytheria属和Cyprideis属。该组合属于上潘诺尼阶的唇缘星介亚带。Krško盆地的介形虫组合在物种组成上与克罗地亚和塞尔维亚的潘诺尼亚介形虫群落相似。

Upper Miocene ostracods from the Krško Basin, SE Slovenia

The purpose of this study was to identify the ostracod assemblage from a 43 m thick section of the Bizeljsko Formation, which constitutes the middle part of the Upper Miocene Posavje Group. The succession comprises sandstone, siltstone, and marlstone, deposited in a delta front environment. The determined ostracods belong to the families Cyprididae, Cytheridae, Darwinulidae, and Loxoconchidae. In total, 30 species were identified. Additionally, 8 morphotypes were determined at the genus level. The most common genera are Candona, Hemicytheria, and Cyprideis. The assemblage belongs to the Caspiocypris labiata subzone from the upper Pannonian. The ostracod assemblage from the Krško Basin is similar in species composition to Pannonian ostracod assemblages from Croatia and Serbia.

期刊介绍： Geologia Croatica welcomes original scientific papers dealing with diverse aspects of geology and geological engineering, the history of the Earth, and the physical changes that the Earth has undergone or it is undergoing. The Journal covers a wide spectrum of geology disciplines (palaeontology, stratigraphy, mineralogy, sedimentology, petrology, geochemistry, structural geology, karstology, hydrogeology and engineering geology) including pedogenesis, petroleum geology and environmental geology. Papers especially concerning the Pannonian Basin, Dinarides, the Adriatic/Mediterranean region, as well as notes and reviews interesting to a wider audience (e.g. review papers, book reviews, and notes) are welcome.
