The Sárrét marshland is situated along the northeastern foothills of the Bakony Mountains, along a NE-SW-trending neotectonic zone. Investigation of the marshland and the reconstruction of its evolution are especially interesting to compare to the present and the expected future stage of Lakes Balaton and Velence. Based on the sedimentological characteristics of the core sequence and the geochemical, physical, and mineralogical composition of the layers, three sedimentological cycles could be separated. The three cycles represent the most important evolutionary phases of lake formation: flourishing and progressive aging. First, a nutrient-poor, open-water lake existed, where clastic sediments (sand and silty clay) were deposited. During the second phase, phytoplankton-produced autogenic lime mud was deposited in the progressively more eutrophic water. Peat accumulation during the third stage indicates the marsh phase of the lake.The results suggest that the studied sequence developed from Late Glacial to Middle Holocene. According to radiocarbon dating the accumulation rate in Sárrét (Sümegi, this volume) corresponds to the sedimentation rates in the Tapolca Basin and Lake Balaton.

Late-Quaternary material of various rodent species remnants (lower jaws and teeth) of different depth and age burials from
zoogenic deposits in karstic cavities of the Urals (Russia) has been analyzed by thermogravimetry, differential thermal analysis,
differential scanning calorimetry, and inductively coupled plasma mass spectrometry. Exothermic peaks position and shape as
well as quantitative values of mass loss and heat effects (especially parameters of organic matter combustion at 200–600 °C)
were found to vary significantly depending on bone’s age and fossilization conditions. On the basis of correlation between
bone organic component and corresponding concentrations of some trace elements, three different types of fossilization had
been proposed. The obtained values of the organic contents in the bone remnants of similar type and location were used to
identify different age admixtures as well as chronologically systematize large sample collections.
