Powierzchniowe utwory geologiczne rezerwatu przyrody Góra Zborów

Abstract

This paper presents the results of a field study on the surficial geological deposits in „Góra Zborów” nature reserve. Research was realized as a part of the project ʺThe Protection and rational use of the special area of conservation of the Natura 2000 habitats, Ostoja Kroczycka, in the Góra Zborów nature reserveʺ. In the nature reserve, apart from Upper Jurassic massy limestones, rock waste and waste clay on limestones and allochthonous silicious Quaternary deposits (medium and fine-grained sand and loess) appears. The humus and plant debris lie on their surface (fig. 1 and 2). These deposits on slopes locally mix and interfinger in layers. The surficial deposits in Góra Zborów are arranged in arc- and ring-shaped bands. Every complex consists of three zones: 1 – central – massive limestone rocks, 2 – transition – stone rubble, 3 – outside – band with predomination of silicious Quaternary deposits. In more morphological diversified parts of slopes the sequence repeats in the form of arcs directing from the outcrop of limestone rocks into the bottom of the slope. The thickness of Quaternary sandy and silty deposits is different, depending on diversified relief of bedrock. The thickness is the largest at the base of the slope.
