Bălcescu Blvd., 010041 Bucharest, *[email protected], **[email protected] Abstract. Mineral resources have been the basis of the progress of human civilization. The relationship between man and mineral resources has developed under auspices of the interaction between the needs, possibilities and requirements. At first, man used stone, most likely for defense and hunting, thus acting alone. Then, by appreciating other benefits of rarer materials, humans began to use metals such as gold, copper, tin, iron, etc. Owing to the genetic association between copper and tin in several metallogenic districts – e.g. Erzgebirge or Cornwall, the primitive man has probably accidentally „produced” bronze – a copper and tin alloy which marked an entire epoch of the human history. In fact, owing to the poor quality of pure iron which

Following Paleogene and older orogenic phases, the ®rst tectonic event which aected the studied area was characterised by Early Miocene large scale extension to transtension which is responsible for the opening of the Getic Depression as a dextral pull-apart basin. Further Middle Miocene contraction caused WNW±ESE oriented thrusts and associated piggy-back basins. The last tectonic episode recognised in the studied area relates to general transpressive deformations during the Late Miocene±Early Pliocene interval, a ®rst NW±SE oriented dextral episode is followed by second N±S sinistral deformations. The detailed sequence stratigraphy study allows for the de®nition of the dominant tectonic control of the sedimentary sequences in foreland basins. A eustatic

  • Fighting Corruption with Con Tricks: Romania's Assault On
    FIGHTING CORRUPTION WITH CON TRICKS: ROMANIA’S ASSAULT ON THE RULE OF LAW David Clark FIGHTING CORRUPTION WITH CON TRICKS FIGHTING CORRUPTION WITH CON TRICKS: ROMANIA’S ASSAULT ON THE RULE OF LAW 2 FIGHTING CORRUPTION WITH CON TRICKS Executive Summary Democracy in Europe is facing its greatest challenge since the fall of the Berlin Wall. The threat comes not only from the rise of political movements that openly reject liberal democratic values, including the governing parties of Hungary and Poland, but also from the risk of creeping authoritarianism caused by a gradual decline in standards of governance and the weakening of important democratic underpinnings, such as the rule of law. Romania is a country of particular concern. Although it has earned international praise for its recent efforts to stamp out corruption, a detailed examination of Romania’s anti-corruption activities shows that they often provide convenient cover for acts of political score settling and serious human rights violations. The methods used show a considerable degree of continuity with the practices and attitudes of the communist era. The strong correlation between those targeted for prosecution and the interests of those in power is indicative of politicised justice. Cases have often been accompanied by campaigns of public vilification designed to maximise their political impact. Far from being above politics, Romania’s National Anti-corruption Directorate (DNA) is an active participant in its partisan struggles. Although the rule of law requires the justice system to work independently of government, there is clear evidence of collusion between prosecutors and the executive in Romania.

  • 27 Scoping Study: Applicability of Pir Systems to Mine Waters in Eastern and Southern Europe
    Scoping study: applicability of PIR systems to mine waters in Eastern and Southern Europe 151 27 SCOPING STUDY: APPLICABILITY OF PIR SYSTEMS TO MINE WATERS IN EASTERN AND SOUTHERN EUROPE 27.1 Project: PIRAMID C. Wolkersdorfer1, A. Hasche1, J. Tschapek1, M. Veselič2, M. Leblanc3 1University Freiberg, Germany 2Institute for Mining, Geotechnology and Environment, Slovenia 3Université Montpellier, France 27.2 Executive Summary Mining in Europe has great influence of the environment. A significant problem in many EU Member States and EU candidate countries is the long-term water pollution from abandoned mines and associated industrial sites. Sources of water pollution are e.g. pyrite oxidation, metal leaching by surface water or rain and leaching of residual process chemicals in the tailings. In order to reach today’s ecological standards polluted mine water needs to be treated in technical water treatment systems (conventional method). Water treatment will be necessary for a long time, consequently conventional methods will not be economically efficient. Key objectives of PIRAMID are to draw developments of passive, ecologically-friendly in-situ remedial methods for mining waters together and to support the development of new tech- niques and innovations in order to apply such technologies to a variety of of polluted mine waters. This report gives an overview of mine water problems in selected EU Member States and Accession States in Eastern and Southern Europe and assesses the potential applicability of passive treatment methods and where such methods are already applied. For most existing mining sites in the reviewed countries the applicability of passive treatment methods is possible. Furthermore, in France, Germany, Poland and the Czech Republic ex- periences with different passive treatment methods e.g.

I, no.1, 2006, pp 31-60 SETTLEMENT HISTORY AND SUSTAINABILITY IN THE CARPATHIANS IN THE EIGHTEENTH AND NINETEENTH CENTURIES David TURNOCK* ∗ Geography Department, The University Leicester LE1 7RH, U.K. Abstract: As part of a historical study of the Carpathian ecoregion, to identify salient features of the changing human geography, this paper deals with the 18th and 19th centuries when there was a large measure political unity arising from the expansion of the Habsburg Empire. In addition to a growth of population, economic expansion - particularly in the railway age - greatly increased pressure on resources: evident through peasant colonisation of high mountain surfaces (as in the Apuseni Mountains) as well as industrial growth most evident in a number of metallurgical centres and the logging activity following the railway alignments through spruce-fir forests. Spa tourism is examined and particular reference is made to the pastoral economy of the Sibiu area nourished by long-wave transhumance until more stringent frontier controls gave rise to a measure of diversification and resettlement. It is evident that ecological risk increased, with some awareness of the need for conservation, although substantial innovations did not occur until after the First World War Rezumat: Ca parte componentă a unui studiu asupra ecoregiunii carpatice, pentru a identifica unele caracteristici privitoare la transformările din domeniul geografiei umane, acest articol se referă la secolele XVIII şi XIX când au existat măsuri politice unitare ale unui Imperiu Habsburgic aflat în expansiune.

Mineralogical studies performed on crusts, nodules and earthy masses from the Romanian caves Gaura cu Muscă, Gaura Haiducească and Peștera Zidită have revealed the presence of three different phosphate associations. The minerals have been identified by means of X-ray diffraction, scanning electron microscopy, and energy dispersive spectroscopy. Five phosphates have been identified in the samples, with hydroxylapatite the only common mineral in all the three caves. Brushite, taranakite, leucophosphite and variscite are the other phosphates identified. Associated minerals include gypsum, calcite, quartz, and illite-group minerals. Aside from differences in the lithology, the occurrences of the different phosphate minerals indicate variable pH and relative humidity conditions near or within the guano accumulations.

  • Paleozoic Tectonostratigraphic Development and Paleogeography of Brunovistulian Terrane and Comparison with Other Terranes at the SE Margin of Baltica-Laurussia
    Journal of the Czech Geological Society 47/34(2002) 81 Late Proterozoic Paleozoic Tectonostratigraphic Development and Paleogeography of Brunovistulian Terrane and Comparison with Other Terranes at the SE Margin of Baltica-Laurussia Svrchnoproterozoický paleozoický tektonostratigrafický vývoj a paleogeografie brunovistulického teránu a srovnání s dalími terány na JV okraji Baltiky-Laurusie (9 figs, 2 tabs) JIØÍ KALVODA1 ROSTISLAV MELICHAR2 ONDØEJ BÁBEK3 JAROMÍR LEICHMANN4 1 Department of Geology and Paleontology, Kotláøská 2, 61137 Brno, [email protected] 2 Department of Geology and Paleontology, Kotláøská 2, 61137 Brno, [email protected] 3 Department of Geology, Tø. Svobody 26, 771 46 Olomouc; [email protected] 4 Department of Geology and Paleontology, Kotláøská 2, 61137 Brno, [email protected] There are close similarities between the Brunovistulian Terrane and the Istanbul Zone both in the Neoproterozoic and Paleozoic. The geological structure, lithology and geochronology of the Cadomian Brunovistulicum show a broad fit with the crystalline basement of the Istanbul Zone. Their Gondwana or Baltica affinity is still poorly constrained and remains a matter of discussion. The Vendian and Cam- brian sequences recognized in the central Malopolska, Brunovistulian and Moesian terranes correlate well with the Scythian Platform. In the Istanbul Zone the presence of pre-Ordovician sedimentary sequences has not been confirmed and may only be anticipated. In Paleozoic the best fit was attained in the DevonianCarboniferous. The sedimentary record in the Zonguldak and Istanbul terranes correlates closely to the Moravian Karst and Ludmírov facies developments of the Brunovistulian Terrane. This correlation is reinforced by the good fit of the main Variscan deformation phases attributed in both the Brunovistulian Terrane and the Istanbul Zone to the late Viseanearly Namurian and Westphalian-Stephanian intervals.
