The process of oxidation of Fe2+ to Fe3+ ions started at about 350 °C for the sample richer in Al and at 300 °C for the sample somewhat lower Al-content. Mössbauer results show that this process may be associated with dehydroxylation or even initiate it. The first stage of dehydroxylation takes place at a temperature > 350 °C when the adjacent OH groups are replaced with a single residual oxygen atom. Up to ~500 °C, Fe ions do not migrate from cis- octahedra to trans-octahedra sites, but the coordination number of polyhedra changes from six to five.

  • Ferns of the Lower Jurassic from the Mecsek Mountains (Hungary): Taxonomy and Palaeoecology
    PalZ (2019) 93:151–185 https://doi.org/10.1007/s12542-018-0430-8 RESEARCH PAPER Ferns of the Lower Jurassic from the Mecsek Mountains (Hungary): taxonomy and palaeoecology Maria Barbacka1,2 · Evelyn Kustatscher3,4,5 · Emese R. Bodor6,7 Received: 7 July 2017 / Accepted: 26 July 2018 / Published online: 20 September 2018 © The Author(s) 2018 Abstract Ferns are the most diverse group in the Early Jurassic plant assemblage of the Mecsek Mountains in southern Hungary and, considering their abundance and diversity, are an important element of the flora. Five families were recognized so far from the locality; these are, in order of abundance, the Dipteridaceae (48% of collected fern remains), Matoniaceae (25%), Osmun- daceae (21%), Marattiaceae (6%) and Dicksoniaceae (three specimens). Ferns are represented by 14 taxa belonging to nine genera: Marattiopsis hoerensis, Todites princeps, Todites goeppertianus, Phlebopteris angustiloba, Phlebopteris kirchneri Barbacka and Kustatscher sp. nov., Matonia braunii, Thaumatopteris brauniana, Clathropteris meniscoides, Dictyophyl- lum nilssoni, Dictyophyllum rugosum, Cladophlebis denticulata, Cladophlebis haiburnensis, Cladophlebis roessertii, and Coniopteris sp. Ferns from the Mecsek Mts. are rarely found in association with other plants. They co-occur mostly with leaves of Nilssonia, leaflets of Sagenopteris, and rarely with other plants. The most commonly co-occurring fern species is P. kirchneri Barbacka and Kustatscher sp. nov. According to our statistical approach (PCA, Ward cluster analysis), the fern taxa cluster in four groups corresponding to their environmental preferences, determined by moisture and disturbance. Most taxa grew in monospecific thickets in disturbed areas; a few probably formed bushes in mixed assemblages, whereas one taxon, P. kirchneri, probably was a component of the understorey in a stable, developed succession of humid environments.

  • Biodiversity and the Reconstruction of Early Jurassic Flora from the Mecsek
    Acta Palaeobotanica 51(2): 127–179, 2011 Biodiversity and the reconstruction of Early Jurassic fl ora from the Mecsek Mountains (southern Hungary) MARIA BARBACKA Hungarian Natural History Museum, Department of Botany, H-1476, P.O. Box 222, W. Szafer Institute of Botany, Polish Academy of Sciences, Lubicz 46, 31-512 Kraków, Poland; e-mail: [email protected] Received 15 June 2011; accepted for publication 27 October 2011 ABSTRACT. Rich material from Hungary’s Early Jurassic (the Mecsek Mts.) was investigated in a palaeoen- vironmental context. The locality (or, more precisely, area with a number of fossiliferous sites) is known as a delta plain, showing diverse facies, which suggest different landscapes with corresponding plant assemblages. Taphonomical observations proved that autochthonous and parautochthonous plant associations were present. The reconstruction of the biomes is based on the co-occurrence of taxa and their connection with the rock matrix and sites in the locality, as well as the environmental adaptation of the plants expressed in their morphology and cuticular structure. The climatic parameters were confi rmed as typical for the Early Jurassic by resolution of a palaeoatmospheric CO2 level based on the stomatal index of one of the common species, Ginkgoites mar- ginatus (Nathorst) Florin. Plant communities were differentiated with the help of Detrended Correspondence Analysis (DCA); the rela- tionship between taxa and sites and lithofacies and sites, were analysed by Ward’s minimal variance and cluste- red with the help

  • Factors Responsible for Crystal Chemical Variations in The
    American Mineralogist, Volume 95, pages 348–361, 2010 Factors responsible for crystal-chemical variations in the solid solutions from illite to aluminoceladonite and from glauconite to celadonite VICTOR A. DRITS ,1 BELL A B. ZV I A GIN A ,1 DOUGL A S K. MCCA RTY,2,* A N D ALFRE D L. SA LYN 1 1Geological Institute of the Russian Academy of Science, Pyzhevsky per. 7, 119017 Moscow, Russia 2Chevron ETC, 3901 Briarpark, Houston, Texas 77063, U.S.A. AB STR A CT Several finely dispersed low-temperature dioctahedral micas and micaceous minerals that form solid solutions from (Mg,Fe)-free illite to aluminoceladonite via Mg-rich illite, and from Fe3+-rich glauconite to celadonite have been studied by X-ray diffraction and chemical analysis. The samples have 1M and 1Md structures. The transitions from illite to aluminoceladonite and from glauconite to celadonite are accompanied by a consistent decrease in the mica structural-unit thickness (2:1 layer + interlayer) or csinβ. In the first sample series csinβ decreases from 10.024 to 9.898 Å, and in the second from 10.002 to 9.961 Å. To reveal the basic factors responsible for these regularities, struc- tural modeling was carried out to deduce atomic coordinates for 1M dioctahedral mica based on the unit-cell parameters and cation composition. For each sample series, the relationships among csinβ, maximum and mean thicknesses of octahedral and tetrahedral sheets and of the 2:1 layer, interlayer distance, and variations of the tetrahedral rotation angle, α, and the degree of basal surface corruga- tion, ∆Z, have been analyzed in detail.

  • Dinosaur Ichnotaxa from the Lower Jurassic of Hungary
    Geological Quarterly, Vol.40,No.l,1996,p.1l9- 128 Gerard GIERLrNSKI Dinosaur ichnotaxa from the Lower Jurassic of Hungary The Early Jurassic strata of the Mecsek Coal Fonnatioo of southern Hungary revealed new dinosaur tracks. Two ichnospecies of Gralla/or /uberosus (Hitchcock 1836) Weems 1992 and Kayen/aplIS soltykovensis (Gierliriski 1991) comb. nov. have been recognized. The iCMotaxonomy of Kayelilaplis is emended and supplemented by a ichnotaxon previously designated as "Gralla/or (Eubrontes) soltykovensis". INTRODUCTION Occurrence of dinosaur tracks in Hungary is restricted to the Early Liassic deposits of the Mecsek Coal Formation, in the Pecs area. The first discoveries were reported from the Vasas mine and Komlo CA. Tasnadi Kubacska, 1967, 1968. 1970; L. Kordos. 1983). Later. dinosaur tracks were also found in the Pecsbanya mine (K. Hips et aI., i989). New material described herein was collected in September, 1995. in the Vasas and Pecsbanya opencast coal mines. Contrary to L. Kordos (1983), the features of hitherto discovered ichnites from Hungary indicate their theropod affinity (not ornithischian, as L. Kordos postulated). The tracks resemble well known cosmopolitan theropod ichnotaxa of Grallator and Kayentapus.

The mica shows a negative correlation between tetrahedral Si and octahedral (AI + Mg), suggesting an Al-celadonitic substitution (Si + VIAl+ VIO = IVAI+ VIMg) and a chemical formula: Kl01(Mg245AlolDo35h~lSi352Alo48h~401O[(OH,0)166Clo34)h~2' The presence of hydroxyl was confirmed by OH stretching modes at 3734 and 3606 cm' in the Raman spectra. Single- crystal X-ray diffraction data provide the unit-cell parameters (space group C2/m, 1M polytype): a = 5.299(4), b = 9.167(3), C = 10.226(3) A, ~ =100.06(4)°, V= 489.1(4) N. The structure refinement shows the presence of vacancies on the octahedral sites (15% for Ml and 6.5% for M2). Chlorine occupies a position about 0.5 A from 04 with partial occupancy (0.39 apfu).

Our study is based on newly collected material from additional track-bearing beds. The description of the two largest preserved surfaces, containing a total of 102 tracks that can be referred to 21 trackways, is provided here. This represents the first attempt to measure, map and compare the tracks of these bipedal, functionally tridactyl dinosaurs in several associated trackways. Significant morphological variability can be observed (e.g. depth, presence or absence of a metatarsal impression, digit length, digit divarication angle) that is explained by differences in physical parameters of the substrate. The mean of pes length is 16.3 cm in tracksite PB1 and 19.9 cm in tracksite PB2.
