Red clays in the central Carpathian Basin (Hungary) (Tengelic Red Clay Formation; Kerecsend Red Clay Formation), overlain by loess-palaeosol sequences, were studied. Results from geochemical climofunctions applied to Upper Pliocene-Lower Pleistocene red clays and palaeosols located in the Carpathian Basin, and clay mineralogy, indicate that the palaeoclimate was considerably more humid and warmer during the Late Pliocene-Early Pleistocene in comparison to modern values. © Tübi̇tak.

The largest and most important dust source areas are situated in the Sahara, from where several hundred thousand tons of mineral dust is emitted each year and transported towards the European continent. Here we show that 130 Saharan dust events (SDEs) reached the atmosphere of the Carpathian Basin from 1979 to 2011 by using the NASA's daily TOMS Aerosol Index data, satellite images and backward trajectory calculations of NOAA HYSPLIT model. Monthly trends of dust events demonstrate that the main period of dust transportation is in the spring, with a secondary maximum in the summer (in July and August). This seasonal distribution match well the seasonality of Saharan dust emissions. However synoptic meteorological conditions govern primarily the occurrence of long-range dust transport towards Central Europe. Based on their different meteorological backgrounds (geopotential field, wind vector and meridional flow), SDEs were classified into three main types. By using composite mean maps of synoptic situations and backward trajectories, the possible source areas have also been identified for the different types of events. Finally, we provide a short discussion on how the African mineral dust could contribute to the local aeolian sedimentation of the Carpathian Basin during the Plio-Pleistocene. © 2012 Elsevier B.V.

They occur in three types in Hungary. (1) The oldest red clays are mainly in situ weathering crusts rich in kaolinite, formed in warm, humid, subtropical or monsoon climate; (2) the younger type is rich in smectite and goethite; and (3) illite and chlorite dominant in the youngest part, which formed under warm and dry climates in savannah, steppe or forest steppe environments, and is of wind-blown origin. Representative samples were selected for study from a large number of profiles. Mineralogical, some micromorphological, and geochemical investigations of typical samples of red clays in Hungary were performed. This review focuses on the origin, development and distribution in the Pannonian basin. (C) 2010 Elsevier Ltd and INQUA. All rights reserved.
