The Jurassic succession of Gorski Kotar reveals the typical sedimentary signature of the inner Adriatic Carbonate Platform realm. On the basis of its facies characteristics eleven informal lithofacies units can be distinguished. By origin, they are grouped into three depositional settings that alternated over the spacious Adriatic platform area during the Jurassic. These are: (1) subtidal below fair-weather wave-base to higher-energy subtidal above fair-weather wave-base, (2) subtidal below fair-weather wave-base with episodic higher-energy influences and (3) peritidal. The alternation of depositional settings reflects periods of intensive, large-scale regional tectonic movements during the geodynamic evolution of the western Neo-Tethys region, such as the opening/closing of the Dinaridic branch of the Neo-Tethys and opening of the Adriatic basin.

The newly discovered crustal xenoliths from Miocene andesites in the Matra Mts (Northeast Hungary) were classified into three petrographic types. Type 1 is a garnetiferous, plagioclase-rich cumulate rock, presumed to originate from the felsic portion of the nearby Szarvasko-Darno mafic igneous complex. The almandine-rich garnet has been inferred to be of granulite facies origin. Garnet - orthopyroxene geothermobarometry on the orthopyroxene - plagioclase corona structure around it indicates a later high temperature (800-950 °C) low pressure (3-4 kbar) retrogression event. Type 2 is also plagioclase-rich cumulate rock with contact metamorphic assemblage containing spinel, corundum and andalusite, which crystallized in the course of dehydration reactions of biotite and/or smectite in hornblende hornfels to sanidinite facies conditions. Type 3 is microsyenite, which contains abundant anorthoclase and minor amount of Na- and K-rich kaersutitic-barkevikitic amphibole.

Quaternary relief evolution of various volcanic areas in Hungary has been determined by (a) the original volcanic succession and related, primary landforms and (b) the subsequent postvolcanic tectonism and erosion. This overview presents some details of these processes through selected relief types from the Miocene volcanic mountains of Hungary: the High Borzsony erosional caldera rim, the Rocks of Vadallo-kovek, the Dobogoko Ridge, the Danube Bend area, and the badlands and fairy chimneys of the southern foreland of the Bukk Mts, by showing different volcanic relief types, and postvolcanic tectonic, paleogeographic and erosional history. In the Quaternary, the tectonic transformation of these and other volcanic areas has been highly variable; in contrast, erosional processes of the Quaternary, i.e. pedimentation, loess and other eolian sedimentation, derasion, periglacial relief formation, and channel erosion, have affected almost all areas in Hungary; hence types and rates of erosion can be well constrained.

The recently encountered Upper Cretaceous (Santonian) Iharkut terrestrial vertebrate locality has yielded several vertebrate taxa since its discovery. Scincomorphan lizards are also represented in this fauna by several jaw fragments. The most abundant of these is represented by seven dentary fragments and an indeterminate jaw fragment with characteristic teeth. The hypertrophied splenial, the heterodont dentition, the cementum deposition at the bases of the teeth, and the large subcircular resorption pits assign this type to the family Teiidae. The dentition is composed of conical, monocuspid teeth in the mesial region and transversely widened bicuspid teeth in the distal region. This morphology is well known in members of the subfamily Polyglyphanodontinae. Based on their dental morphology the Iharkut finds can be easily assigned to the genus Bicuspidon. This genus is known from two species, B. numerosus Nydam et Cifelli 2002 from the Albian-Cenomanian of Utah (North America) and B. hatzegiensis Folie et...

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.

The basement of the Pannonian Basin is made up of tectonostratigraphic terranes of varying origin. They gradually amalgamated to form the large Alcapa and Tisza-Dacia composite terranes that were juxtaposed during the Tertiary. In North Hungary, in the basement of the Tertiary volcanic complex of the Matra Mts and in the western part of the Bukk Mts, remnants of a Jurassic accretionary wedge were encountered. Ore exploration boreholes encountered several hundred-meter thick carbonate and siliceous shale-radiolarite successions in the basement of the Matra Mts (Darno Complex). Based on detailed studies of Core Recsk-109, the carbonate succession consists predominantly of grainstone with packstone-wackestone intercalations. Peloidal bioclastic grainstone is the most common texture type but sand-sized intraclasts and oncoid and ooid grains also occur locally. The most spectacular feature is the large amount of coarse to medium sand-sized fragments of calcified cyanobacteria ("Porostromata"). Platform-derived...

We present the main petrographic and geochemical features of the Lower to Middle Eocene turbiditic sandstones from the northwestern portion of the External Dinaride flysch basin. Sampled areas cover SW Slovenia (Vipava and Brkini Basins) and the Istrian Peninsula (Trieste-Koper and Pazin Basins). Framework constituents of the lithic arenites reveal low-grade metamorphic, acidic plutonic, and to a lesser extent, mafic volcanic and ultrabasic sediment sources, with evidence for a small degree of sediment recycling as well. Among the processes that commonly influence sediment compositions, weathering in the source and sorting were probably negligible, but carbonate contribution of detrital or intrabasinal origin diluted the siliciclastic portions to various degrees. Main and trace element compositional data agree well with petrography and clearly indicate the predominance of felsic, crustal source lithologies. Exposed mafic-ultramafic source units were volumetrically less important. From the Early Paleogene, extensive sediment mixing occurred in front of the Dinaride orogenic thrust wedge, with the components derived from different Dinaride units of felsic crystalline basement, platform carbonates and ophiolite. In the Eocene, a likely source of the mafic-ultramafic detritus was the Jurassic ophiolitic melange in the NE Dinarides.

In this paper, first the definitions of variability and ergodicity are discussed. This is followed by an overview of variography, and the importance of sequential stochastic simulation is emphasized. The main uncertainties of variograms are discussed, followed by the methods for decreasing this uncertainty. It is stressed that additional geologic information can be obtained from variograms, even beyond the ranges of influence. Possibilities of local evaluation of the gh values and ranges of influence are presented. The main idea of the paper is that the gh values and the ranges of influence are continuous random variables. Up to now variograms were evaluated mainly for geomathematical purposes and their direct geologic evaluation was neglected. The author presents examples of such kinds of evaluation.

The metamorphic basement of the Pannonian Basin consists of uplifted highs and deep sub-basins among them. One of the best-known highs is the so-called Szeghalom Dome, which is surrounded by less intensely explored ones. The eastern neighbour, the Mezosas-Furta Dome (MFD), is studied in this paper. Based on detailed petrologic investigation, six main lithologies are distinguished for the MFD, which can be well compared to those described previously for the Szeghalom Dome. All these rock types (orthogneiss, mafic-ultramafic xenolith, granite, sillimanite-biotite gneiss, garnet-bearing amphibolite, amphibole-biotite gneiss) are classified into three main units based on different metamorphic and deformation history. Understanding their relative spatial position permitted the elaboration of geologic map and sections of the MFD.

The Middle Triassic Wetterstein Limestone was investigated on the Feuerkogel, in the eastern Hollengebirge 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.
