Molnár Béla–Szónoky, Miklós: On the Origin and Geohistorical Evolution of the Natron Lakes of the Bugac Region

In the summer half of the year, — especially during the dry hazelnut phase when the ground-water table lay deeper than today on the Danube

—Tisza Interfluve Ridge — a surface rising almost 40 m above the alluvium of the Tisza, the predominantly northwest-southeast oriented winds arranged the wind-blown sands so as to form northwest-southeast trending dunes that would be separated by depressions of similar direction (I. Miháltz 1953). On the Ridge it is these depressions that made possible the formation of shallow lakes, that of the Bugac lakes inclusive (Fig. 1). On account of the higher water table of the more humid post-hazelnut periods, permanent lakes of shallow water could be formed which would not dry out but in exceptionally few cases, and most of which have been aligned in northwest-southeast direction corresponding to the trend of the dune ranges. The stratigraphy of the Latest Pleistocene and Holocene sediments of the Danube
