Natural Radioactive Element Content of the Old Crystalline Rocks in Southern Transdanubia (Sw Hungary)
Acta Mineralogica-Petrographica, Szeged, XL, 121-138, 1999 NATURAL RADIOACTIVE ELEMENT CONTENT OF THE OLD CRYSTALLINE ROCKS IN SOUTHERN TRANSDANUBIA (SW HUNGARY) E. PÁL MOLNÁR*, I. VADOS**, I. GERZSON**, B. KÓBOR* •Department of Mineralogy, Geochemistry and Pétrology, Attila József University "Mecsekérc Environment Protection Co. ABSTRACT On the basis of systématisation of several thousand radioactive element content analyses made in laboratories since the 50's, U and Th content of old granitoid rocks of Southern Transdanubia proved to be much higher than the average U and Th content of granitoids in the world. This value of rocks from areas west of Mecsek Mountains as well as near Szalatnak village and Pecs city is twice higher than the world average. Areas west of the Mecsek Mountains show higher U and lower Th contents than areas east of these mountains. Uranium accumulation is higher in aplites and hydrothermal formations than in granites. The western and eastern granites are less and highly sensitive to leaching, respectively. The intensive U migration resulted in significant U accumulation in young sediments in some places. INTRODUCTION Study of natural radioactive element (U /Ra1, Th, K) content of the rocks in Hungary was performed by the Mecseki Ércbányászati Vállalat (Mecsek Ore Mining Company) until 1990, when uranium exploration was stopped in Hungary. Aim of the analyses was to research U sources, therefore, rocks supposed to contain perspective U accumulation were mainly studied. The aim of this paper is to elaborate many thousands radiological data of granitoid rocks, gneisses and amphibolite-like metamorphic rocks coming from Southern Transdanubia (south of the Szekszárd-Kaposvár-Kutas line to the state boundary, and east of the Kutas-Csokonyavisonta-Barcs line to the Danube). -
The Budapest Housing Market Structure from a Heterodox Economics Perspective and with a Neural Network Classification

O. Box 5030 2600 GA Delft The Netherlands Email: [email protected] The Budapest housing market structure from a heterodox economics perspective and with a neural network classification Abstract: The development of the housing markets in different European metropolitan areas is of high interest for the urban development and the real estate markets, which are about to globalise. What sort of pricing mechanism is able to explain the house prices in different areas? The Budapest housing market is well-suited for scrutiny from an institutional and evolutionary perspective. The housing market is very fragmented with respect to location; several different house types, age-categories and price-levels, as well as micro-locations, are to be found side by side. It is an extremely patchy and multi-faceted setting, and running the data with neural network modelling techniques, namely the self-organizing map (the SOM) and the learning vector quantification (the LVQ), together with conducting the conceptual level analysis using a heterodox economics framework and some qualitative material, sheds some light about the systematic to the degree the market is affected by physical and socio- demographic characteristics, price and regulation.

Introduction As global economic functions are increasingly articulated at a local level, today territorial competition cannot be understood as a process that is contained within national boundaries. -

Debrecen 2008 Adatok a Baranyai-dombság flórájához PURGER Dragica Pécsi Tudományegyetem, TTK, Biológiai Intézet, Állatökológia Tanszék, H-7624 Pécs, Ifjúság útja 6. [email protected] Bevezetés A Mecseken és környékén végzett botanikai kutatások több mint kétszáz éves történetét HORVÁT Adolf Olivér munkái foglalják össze (HORVÁT 1942, 1958, 1975, 1976, 1977). Az elmúlt évtizedekben végzett florisztikai felmérések eredményei számos adattal gazdagították ismereteinket a Baranyai-dombság növényvilágáról (KEVEY 1986, 1988, 1995, 2001, KEVEY & HORVÁT 2000, DÉNES 1997, TÓTH 1998, 1999, 2000). Az utóbbi öt évben országszerte intenzív terepbotanikai kutatások folytak, és a legújabb eredmények (K EVEY 2004, PÁL 2002 a, b, 2003, PURGER 2002 a, 2002 b, CSIKY et al. 2005) arról tanúskodnak, hogy a vizsgált terület még sok feltáratlan botanikai értéket rejt. A vizsgált terület és módszerek A Baranyai-dombság a Mecsekt ől délre-délkeletre terül el. Négy részre tagolódik. Délen a Pécsi-síkság, attól északkeletre, pedig a Geresdi-dombság helyezkedik el. Legnagyobb részét a Dél-Baranyai dombság kistáj teszi ki. A Baranyai-dombság negyedik részét, mint egy sziget a Villányi hegység képezi (MAROSI & SOMOGYI 1990). Ez utóbbi tájegységet azonban e munkában mell őzzük, tekintettel arra, hogy a növényföldrajzi dolgozatokban a Villányi-hegységet általában külön (pl. MOLNÁR 1999), vagy a Mecsekkel együtt tárgyalják (pl. BORHIDI 2006). A félreértések elkerülése végett itt jegyzem meg, hogy az el őző cikkemben (PURGER 2002 a) a „Baranyai-dombság” név alatt a Dél-Baranyai dombságot értettem. Mindazonáltal, az egész térséget, és ezt a területet is, a geográfusok és a botanikusok több néven tárgyalyák: pl.: Mecsekalja (HORVÁT 1942), Tolna-Baranyai dombvidék (BORHIDI 2006, PÁL 2003). -

The Karpatian (Late Early Miocene) Flora of the Mecsek Area
Acta Palaeobotanica 60(1), 51–122, 2020 e-ISSN 2082-0259 https://doi.org/10.35535/acpa-2020-0003 ISSN 0001-6594 The Karpatian (late early Miocene) flora of the Mecsek area LILLA HABLY Botanical Department, Hungarian Natural History Museum, H-1431 Budapest, P.O. box 137, Hungary; e-mail: [email protected] Received 9 September 2019; accepted for publication 28 January 2020 In remembrance of the beautiful summers spent collecting with my family in the Mecsek Mountains ABSTRACT. A rich macroflora has been collected from Karpatian (late early Miocene) layers of the Mecsek Mts during recent decades. The bulk of the fossil assemblage consists of leaves and also fruits of angiosperms. Among the more than a hundred taxa, several endemic species were described: Leguminocarpum mecsekense Andreánszky, Ailanthus mecsekensis Hably, Nyssa gyoergyi sp. nov., Nyssa gergoei sp. nov., Nyssa sp. 1, Clematis csabae sp. nov., Gordonia sp. and Carpolithes gergoei Hably et Erdei sp. nov. Many taxa were last recorded in the Carpathian Basin, e.g. Cedrelospermum, Ziziphus. Other taxa appeared in this flora, e.g. Quercus kubinyii, Podocarpium podocarpum, Liquidambar europaea and Populus populina, and later became dominant in the middle Miocene (Sarmatian) floras or even in the late Miocene (Pannonian) floras. Four main vegetation types were determined. The most significant types are subxerophytic vegetation showing high diversity, swamp veg- etation, riparian vegetation, and a vegetation type growing in habitats with higher rainfall. Thermophilous flora elements are dominant in the assemblage, although “arctotertiary” species also appear. The floristic character of the flora supports the results of an earlier quantitative climate analysis of the Magyaregregy flora, accord- ing to which mean annual temperature was 15.6–16.6°C and coldest-month and warmest-month temperatures were 5–6.2°C and 24.7–27.9°C, respectively. -

Sideritic–Kaolinitic and Green Clay Layers in the Mecsek Mountains (SW Hungary): Indicators of Middle Triassic Volcanism–Myth Or Reality?

The aim of the present study is to provide a review and a critical re-evaluation of the previously pub- lished data on both the sideritic–kaolinitic layers (the so-called “Mánfa Siderite”) and the green clay layers. New results of mineralogical investigation of the green clay layers are also presented. The Middle Triassic volcanic origin of the “Mánfa Siderite” cannot be confirmed. In addition to a possible volcanic contribution, the sideritic–kaolinitic layers were probably formed in a freshwater swamp under humid, tropical climatic conditions, whereby weathering in an organic-rich, acidic environment led to the for- mation of “underclays” and siderite in the coal-bearing formations of Late Triassic to Early Jurassic age. -

LET’S GET STARTED Approximately 10 percent of the area of Hungary is under nature pro- tection. Mountain ranges covered in dense forests, gently waving hills, the wilderness of floodplains, endless plains and karstlands hiding unparalleled treasures follow one another in our ten national parks, 39 protected landscape areas and numerous nature reserves. We are now inviting You to discover them. BUT BEFORE STARTING, LET’S SEE THE MEANING OF SOME TERMS... …nature conservation visitor centre Located beside a key entrance point to, or in a central area of, the national park, so a recommended starting point for all trips. The trained staff of the national park can provide information about the options to wander the protected natural area. Additionally, the interactive exhibition in the visitor centre is open, regardless of weather, to learn about the rich natural and cultural heritage of the na- tional park and see into local nature conservation activities. Moreover, we can also buy publications, souvenirs remindful of trips in, and products associated with, the national park. …educational trail Thematic hiking trail, showing the natural and cultural heritage of the designated area in various stations, on display boards and in publications. Especially recommended for people who like to experience nature alone and in an active way. UNESCO Global Geoparks in Hungary give an insight into our values in earth science, following the increasingly popular geo-trips. …thematic nature conservation exhibition site Ecotourism facility, offering a detailed display of specific segments of our natural or cultural herita- ge. Several spectacular geological exhibition areas, tourist caves unfolding the wonders of underg- round world and demo farms with a stock of traditional Hungarian farm animals await their curious visitors in Hungarian national parks. -

Alteration of Triassic Carbonates in the Buda Mountains —
Central European Geology, Vol. 52/1, pp. 1–29 (2009) DOI: 10.1556/CEuGeol.52.2009.1.1 Alteration of Triassic carbonates in the Buda Mountains – a hydrothermal model Mateu Esteban Tamás Budai Szalai Grup S.L., Mallorca, Spain Hungarian Geological Institute Erika Juhász Philippe Lapointe Szalai Grup S.L., Mallorca, Spain TOTAL S.A., Larriabau, France Large, irregular volumes of altered, friable Triassic dolomite with poorly recognizable depositional fabrics crop out in the Buda Mountains, Hungary. These rock volumes are characterized by powder- like, chalky, soft, whitish gray microporous carbonates, referred to as "pulverized dolomite". This is interpreted as the result of corrosion of carbonates along microfractures. The pulverized dolomite is commonly associated with silica and clay cementation ("silicification") and "mineralization" of iron- rich minerals, barite, sphalerite, galena, fluorite, calcite, dolomite and others, clearly pointing out hydrothermal Mississippi Valley Type (MVT) conditions. The pulverization, silicification and mineralization are considered to be a diagenetic facies association (PSM facies). Tectonic shear corridors played an important role in the development of PSM facies as carriers of hydrothermal fluids, but the geometry of the altered units is very irregular and cross-cuts different Triassic depositional facies in addition to Eocene limestone and Middle– Upper Miocene sediments. The PSM facies represents the early stages of hydrothermal alteration (i.e. the burial phase) that was later modified by thermal mixing zones. Pulverized dolomite bodies that reached the surface were strongly affected by meteoric fluids; peculiar speleo-concretions were formed by calcite cementation of the powdery dolomite clasts. The altered carbonates show major porosity development whereas the unaltered carbonates present only minor porosity.
