摘要

摘要在维也纳市维也纳盆地西缘钻探的萨尔马提亚和潘诺尼岩心揭示了中新世中晚期过渡时期复杂的海洋和湖泊沉积环境序列。详细研究了两个萨尔马提亚阶和两个潘诺尼阶海侵-海退序列。海底动物群落的相同序列和磁化率测井中的相似模式是这些序列的特征。这样就可以对维也纳盆地一条主要边缘断层上约3.5公里的钻孔进行对比。生物地层学数据，结合沉积速率的粗略估计，揭示了这些序列之间的巨大差距，表明只有主要的海侵到达了这个边缘区域。特别是，在萨尔马提亚-潘诺尼过渡时期，盆地边缘完全出现，并在至少600 ka的时间内变成陆地环境。

The Sarmatian/Pannonian boundary at the western margin of the Vienna Basin (City of Vienna, Austria)

Abstract Sarmatian and Pannonian cores, drilled at the western margin of the Vienna Basin in the City of Vienna, reveal a complex succession of marine and lacustrine depositional environments during the middle to late Miocene transition. Two Sarmatian and two Pannonian transgressive-regressive sequences were studied in detail. Identical successions of benthic faunal assemblages and similar patterns in magnetic susceptibility logs characterise these sequences. This allows a correlation of the boreholes over a distance of ~3.5 km across one of the major marginal faults of the Vienna Basin. Biostratigraphic data, combined with rough estimates of sedimentation rates, reveal large gaps between these sequences, suggesting that only major transgressions reached this marginal area. In particular, during the Sarmatian-Pannonian transition, the basin margin completely emerged and turned into a terrestrial setting for at least 600 ka.

期刊介绍： AUSTRIAN JOURNAL OF EARTH SCIENCES is the official journal of the Austrian Geological, Mineralogical and Palaeontological Societies, hosted by a country that is famous for its spectacular mountains that are the birthplace for many geological and mineralogical concepts in modern Earth science. AUSTRIAN JOURNAL OF EARTH SCIENCE focuses on all aspects relevant to the geosciences of the Alps, Bohemian Massif and surrounding areas. Contributions on other regions are welcome if they embed their findings into a conceptual framework that relates the contribution to Alpine-type orogens and Alpine regions in general, and are thus relevant to an international audience. Contributions are subject to peer review and editorial control according to SCI guidelines to ensure that the required standard of scientific excellence is maintained.
