摘要

首次介绍了法罗尼页岩的岩性特征和年龄分析。Farony页岩产于Bystrica亚单元的Lubomierz和Rabka地区。位于坎帕系-古新世罗皮亚卡组中、薄层砂质为主的浊积岩中。它由红色页岩层状或层间与强烈生物扰动的绿色页岩组成。法罗尼页岩在约25公里的距离上以窄带的形式暴露。根据凝集有孔虫的年龄估计了该杂化矿床的年龄至坎帕晚期-马斯特里赫特早期。它们的沉积与低能量条件和砂质物质向马古拉盆地内部供应的暂时限制有关。

The Upper Cretaceous variegated shales in the Ropianka Formation of the Magura Nappe (Outer Carpathians) – age and lithostratigraphic position

The lithological characteristics and age analysis of the variegated Farony Shale are presented for the first time. The Farony Shale occurs in the Lubomierz and Rabka areas in the Bystrica Subunit. It is located within medium- and thin-bedded sandy dominated turbidites of the Campanian–Paleocene Ropianka Formation. It is comprised of red shales laminated or interlayered with strongly bioturbated green shales. Exposures of the Farony Shale are observed along a distance of ~25 km, in the form of a narrow belt. The age of the variegated deposits is estimated based on agglutinated foraminifera to late Campanian–earliest Maastrichtian. Their deposition was associated with low-energy conditions and a temporary limitation of the supply of sandy material to the inner part of the Magura Basin.

期刊介绍: The policy of the Geological Quarterly is to publish significant contributions of information and geological insight relevant to an international readership. The journal has been issued since 1957 at the Polish Geological Institute - National Research Institute and, at present, is the leading Earth sciences journal in Poland. All aspects of Earth and related sciences, and universal and broad regional rather than locally oriented topics are covered. The journal is intended to be an international forum for the exchange of information and ideas, particularly on important geological topics of Central Europe.
