摘要
本文介绍了位于克罗地亚姆列特国家公园内的 Spila nad Procjepom 洞穴的首批古生物学研究成果。所获得的古动物学数据有助于部分了解当地的植被覆盖情况、所研究沉积物(约公元前 3500 年)堆积过程中植被的时间变化以及影响古动物组合的沉积后过程。古乐彩网分析结果表明了从河道沉积到古河道沉积再到陆地环境的变化。虽然由于缺乏统计意义,对植物覆盖率变化的解释需要谨慎,但保存下来的花粉类型证实了地中海常绿森林植被在姆列特岛的主导地位。此外,高比例的非荒野花粉(NAP)表明了某种程度的森林退化,从地中海疏林到退化的灌木丛不等。丰富的木炭也证实了洞穴曾有人类居住。
First palynological results from Spila nad Procjepom cave, Mljet island (Croatia)
This paper presents the first results of palynological research from the Spila nad Procjepom cave, situated in the Mljet National Park, Croatia. The palynological data obtained, enables a partial insight into the local vegetation cover, temporal changes in the vegetation during the accumulation of studied deposits (at ca. 3500 cal years BP), and post-depositional processes that influenced the palynomorph assemblage. Results of palynofacies analysis indicate changes from fluvial (channel deposits), through palustrine to terrestrial environments. Although the interpretation of changes in plant cover, due to the lack of statistical significance, should be taken with caution, preserved pollen types confirm the dominance of the Mediterranean evergreen forest vegetation on Mljet island. Moreover, a high proportion of non-arboreal pollen (NAP) indicates some level of forest degradation, ranging from Mediterranean open forest to degraded maquis. Abundant charcoal additionaly confirms that the cave was inhabited by humans.
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.
