Abstract

Here, we report on the first radiometric dating of pre-Quaternary sinters covering the ENE–WSW striking vertical faults filled with Upper Badenian sands (neptunian dykes) in Mesozoic carbonates of the Devín quarry in the Malé Karpaty Mountains. The 238U/206Pb age of 13.98±0.56 Ma fits well with the former age prediction based on biostratigraphic evidence. Our results provide fault opening age, refine the age of sediments and fossils preserved in the neptunian dykes, and constrain the onset of Badenian sea transgression.

巴登尼亚海王星岩脉断层壁上烧结壳(流岩)化石的238U/206Pb年龄(Devín采石场)

本文报道了mal Karpaty山脉Devín采石场中生代碳酸盐岩中覆盖ENE-WSW走向垂直断层(上巴登尼亚砂)的前第四纪烧结矿的首次放射性定年。238U/206Pb年龄为13.98±0.56 Ma，与前人基于生物地层证据的年龄预测吻合较好。我们的研究结果提供了断层开放年龄，精炼了海王星岩脉中保存的沉积物和化石的年龄，并限制了巴登尼亚海侵的发生。

期刊介绍： GEOLOGICA CARPATHICA covers a wide spectrum of geological disciplines including geodynamics, tectonics and structural geology, volcanology, stratigraphy, geochronology and isotopic geology, karstology, geochemistry, mineralogy, petrology, lithology and sedimentology, paleogeography, paleoecology, paleobiology and paleontology, paleomagnetism, magnetostratigraphy and other branches of applied geophysics, economic and environmental geology, experimental and theoretical geoscientific studies. Geologica Carpathica , with its 60 year old tradition, presents high-quality research papers devoted to all aspects not only of the Alpine-Carpathian-Balkanian geoscience but also with adjacent regions originated from the Mediterranean Tethys and its continental foreland. Geologica Carpathica is an Official Journal of the Carpathian-Balkan Geological Association.
