The Middle Triassic Wetterstein Limestone was investigated on the Feuerkogel, in the eastern Höllengebirge area, Austria. Cephalopod-bearing coquina interbeds consisting predominantly of orthocone cephalopods were found within the dasycladacean inner platform lagoon facies. Based on sedimentological studies the coquina beds are interpreted as storm accumulations. Dasycladacean biostratigraphic data permit assigning the studied succession to the Late Anisian-Early Ladinian interval. Ammonites of age-diagnostic value found in the coquina horizon suggest the Avisianum Subzone of the Reitzi Zone that corresponds to the upper part of the Anisian.

The present article discusses the applicability of thermoanalytical methods in the analysis of Hungarian soils formed on carbonate rocks. Up to now only limited mineralogical and soil chemical research has been done on these soils. Soils from the Bükk Mountains, the most varied limestone region in Hungary, were used for the investigations. The aim was to extend our incomplete knowledge on the mineral composition and formation processes of these soils and to demonstrate the possibilities and evaluation potential of thermoanalytical techniques. All the soils investigated were formed on limestone and had different surface soil thickness, influenced by the accumulation of silicate debris and the microterrain. The results of soil mineralogical analysis revealed an extraordinarily high proportion of quartz compared to that of other minerals (especially calcite), indicating that these soils could not have originated solely from the weathering of the limestone bedrock. The results also showed that thermoanalytical methods could complement classical chemical and instrumental (XRPD) methods in research on the genesis of soils formed on limestone.

A Jurassic marginal depositional system of the Adriatic carbonate platform was analyzed in order to determine its depositional architecture and major depositional controls. Based on their facies characteristics, seven lithofacies units have been distinguished, which constitute four paleoenvironmental associations: top of the platform (shallow subtidal below and above the fair-weather wave-base), upper foreslope, toe-of-slope and basin. The environmental changes are interpreted to be related to tectonic activity as a consequence of regional extensional movements, connected with the opening of the Dinaridic branch of the Neo-Tethys. These extensional movements resulted in multi-stage drowning of the northeastern part of the Adriatic carbonate platform, leading to its gradual back-stepping and accordingly the expansion of the pelagic basin. The interpretation presented here can serve as a useful model for re-evaluating previously analyzed sections of the Adriatic Carbonate Platform margin.
