Abstract

This study presents new discoveries of vascular plants and the trace fossil Dictyodora liebeana (GEINITZ) from the Devonian–Carboniferous Kucaj-Zvonce flysch of the Carpatho-Balkanides and the implications of this fossil association for its sedimentary setting. The occurrence of the described plant debris in a deep-marine environment indicates the presence of hyperpycnites within the siliciclastic turbidites exposed at the Kostadinovica locality. The sedimentological data and the characteristics of the fossil material support the proposed model in which the sediment was at least partially transported by hyperpycnite currents. Furthermore, based on the assessment to similar palaeofloras from comparable formations, the age of the fossil plants can be determined as Early Carboniferous. This can be used as an additional biostratigraphic criterion given the relative abundance of vascular plants in other localities of the Kucaj-Zvonce flysch described in previous studies. The age and the depositional setting of the succession is further better constrained by the first observation of Dictyodora liebeana (GEINITZ) in the Carpatho-Balkanides of Serbia.

喀尔巴阡-巴尔干山脉泥盆系-石炭系复理石岩中的高长岩(塞尔维亚东部Kostadinovica)

本研究介绍了在Carpatho Balkanides的泥盆纪-石炭纪Kucaj Zvonce复理石中发现的维管植物和微量化石Dictyodora liebeana（GEINITZ）的新发现，以及该化石组合对其沉积环境的影响。所述植物碎屑在深海环境中的出现表明，在Kostadinovica地区暴露的硅质碎屑浊积岩中存在超重晶岩。沉积学数据和化石材料的特征支持了所提出的模型，在该模型中，沉积物至少部分由超密度洋流输送。此外，根据对可比地层中类似古植物群的评估，植物化石的年龄可以确定为早石炭世。考虑到先前研究中描述的Kucaj Zvonce复理石其他地区维管植物的相对丰度，这可以作为一个额外的生物地层学标准。该层序的年龄和沉积环境进一步受到塞尔维亚Carpatho Balkanides首次观察到的Dictyodora liebeana（GEINITZ）的限制。

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.
