Survey of the buried paleosol under the Lyukas mound in Hungary

Abstract

The pedological, micromorphlogical, and biomorphic study of the Kurgan called the Lyukas (Hollow) mound situated near the town of Hajdunanas (Great Plain, Hungary) has been performed for the purpose of reconstructing the ancient environment of the mound and its surroundings and in order to examine the paleosol buried underneath the formation. According to the macromorphological examinations, the former original soil formation belongs to the Chernozem type of soils and can be characterized by similar qualities. The existence of an undisturbed paleosol and a modernlike Chernozem type soil was proven both by the micromorphological examination and the biomorphic analysis. The results of the laboratory analysis of the chemical and physical soil qualities confirm the same. The undertaken research pointed out that aqueous impacts predominated in the evolution of the parent material. The existence of sodic mosaic patches within a Chernozem dominated landscape cannot be excluded yet at this mound, which is located near the Hortobagy region, which is well-known for its unique sodic soil areas.
