  • Proceedings of the International Workshop Monitoring Tailor-Made
    PROCEEDINGS MTM-III - OPENING AND INTRODUCTION OPENING AND INTRODUCTION A.R. van Bennekom Institute for Inland Water Management and Waste Water Treatment RIZA, P.O. Box 17, 8200 AA Lelystad, The Netherlands Mr Chairman, ladies and gentlemen, Welcome to the third international workshop Monitoring Tailor-Made. The subject of our workshop is information for sustainable water management. Sustainable water management is a matter of balancing. There are many stakeholders that share the same water resources and decision makers have to find a balance between all these interests. To support good decisions, that integrate between all interests, water management policy needs good, integrated information. Decisions have to balance ecological, economic and sociological factors that influence the quality and quantity of the water, and consequently the required information should integrate these disciplines. In this workshop we will be discussing what kind of information water management policy needs to be able to make decisions, and how such information can be obtained. WATER CRISIS Good information is becoming ever more important. There is a water crisis today. But the crisis is not about having too little water to satisfy our needs. It is a crisis of managing water so badly that billions of people, and the environment, suffer badly (Cosgrove and Rijsberman 2000). Managing water in a sustainable way requires good information. The problem as described by the Prince of Orange is that we have too little, too much or too polluted water. At the second World Water Forum, this is extensively discussed, and it was concluded in the Ministerial Declaration of The Hague on Water Security in the 21st Century that an integrated water resources management is needed, accounting for social, economic and environmental factors and integrating surface water, groundwater and the ecosystems through which they flow.

  • Evidence for a Stratigraphic Basis for the Anthropocene
    Evidence for a Stratigraphic Basis for the Anthropocene Colin N. Waters, Jan Zalasiewicz, Mark Williams, Simon J. Price, Jon R. Ford and Anthony H. Cooper Abstract The Anthropocene was proposed as a term (Crutzen and Stoermer 2000) before consideration was given to the nature of the key signatures, contrasting with standard procedures for defining such units. The term is being widely used in both popular and scientific publications before a decision is made as to whether it warrants formalisation and definition of a Global Stratigraphic Section and Point (GSSP). The deliberate human modification of the landscape and its subsurface, and the creation of human-generated novel sedimentary deposits, minerals, and landforms, are characteristic features of the development of Earth’s surface and near surface, which has accelerated in the past two centuries. The large-scale intentional excavation, transportation, and deposition of mixtures of rock and soil to form anthropogenic deposits and landforms represent a new geological process that could be used as a diagnostic signature of the Anthropocene. Keywords Anthropocene Á Stratigraphy Á Anthropogenic deposits Stratigraphic Issues Related to Anthropogenic Deposits The ground surface and deposits immediately beneath are an open system prone to modification through urban redevelopment, agricultural ploughing, and soil for- mation. This system may be the product of several phases of ongoing evolution and therefore dating this interval is problematic. The history of excavation in C. N. Waters (&) Á S. J. Price Á J. R. Ford Á A.

  • Palaeozoic Formations from Dobrogea and Pre-Dobrogea – an Overview
    Turkish Journal of Earth Sciences (Turkish J. Earth Sci.), Vol.A. 21, SEGHEDI 2012, pp. 669–721. Copyright ©TÜBİTAK doi:10.3906/yer-1101-20 First published online 11 December 2011 Palaeozoic Formations from Dobrogea and Pre-Dobrogea – An Overview ANTONETA SEGHEDI National Institute of Marine Geology and Geoecology, 23−25 Dimitrie Onciul Street, 024053 Bucharest, Romania (E-mail: [email protected]) Received 19 January 2011; revised typescript received 02 November 2011; accepted 11 December 2011 Abstract: An overview of lithological, palaeontological and geochronological evidence existing for the Palaeozoic formations from Dobrogea and Pre-Dobrogea has enabled a better understanding of the Palaeozoic history of these areas. Th e Lower Palaeozoic of Pre-Dobrogea, in places in continuity with the pelitic-silty facies of the underlying Vendian (Ediacaran) deposits, was one of the peri-Tornquist basins of Baltica, suggesting that the Scythian Platform in the Pre-Dobrogea basement represents the rift ed margin of the East European Craton. In North Dobrogea two types of Palaeozoic succession have formed in diff erent tectonic settings. Deep marine Ordovician–Devonian deposits, including pelagic cherts and shales, associated with turbidites, and facing Devonian carbonate platform deposits of the East European Craton, form northward-younging tectonic units of an accretionary wedge, tectonically accreted above a south-dipping subduction zone. South of the accretionary prism, the basinal to shallow marine Silurian–Devonian deposits of North Dobrogea, showing a similar lithology to the East Moesian successions, accumulated on top of low- grade Cambrian clastics with Avalonian affi nity indicated by detrital zircons. Late Palaeozoic erosion was accompanied by deposition of continental alluvial, fl uvial and volcano-sedimentary successions, overlying their basement above an imprecise Carboniferous gap.

    Geological Quarterly, 2006, 50 (1): 59–76 Development of Trans-European Suture Zone in Poland: from Ediacaran rifting to Early Palaeozoic accretion Jerzy NAWROCKI and Pawe³ POPRAWA Nawrocki J. and Poprawa P. (2006) — Development of Trans-European Suture Zone in Poland: from Ediacaran rifting to Early Palaeozoic accretion. Geol. Quart., 50 (1): 59–76. Warszawa. This contribution summarizes selected results of the “Palaeozoic Accretion of Poland” Project. Emphasis is placed on geochronological, geochemical and palaeomagnetic constraints on the Late Neoproterozoic to Early Palaeozoic development of the Trans-European Suture Zone (TESZ). During the Late Neoproterozoic break-up of Rodinia, a major rift developed in the area of the future TESZ along which Baltica was separated from peri-Gondwana and Laurentia, resulting in opening of the Tornquist Ocean and development of the south- western Baltica passive margin. This was paralleled by the development of the Cadomian orogenic system along the margin of Gond- wana and the eastern and southern margins of Baltica. Some tectonic units involved in the TESZ, such as the Brunovistulian Terrane and the Ma³opolska Massif characterized by Cadomian basement, were derived from the internal and external parts of the Cadomian Orogen, presumably somewhere at the SE or SW corners of Baltica. Determination of areas where these terrains were originally located depends strongly on the Ediacaran plate model that is adopted for Baltica. The Ma³opolska Massif was re-accreted to Baltica, presumably due to latest Ediacaran strike-slip tectonics, during the late Middle to Late Cambrian, causing at that time an interruption of its passive margin subsidence pattern and minor erosion.

  • Depositional History and Tectonic Regimes Within and in the Margins of the Fennoscandian Shield During the Last 1300 Million Years
    Working Report 2006-43 Depositional History and Tectonic Regimes within and in the Margins of the Fennoscandian Shield During the last 1300 Million years Seppo Paulamäki Aimo Kuivamäki May 2006 POSIVA OY FI-27160 OLKILUOTO, FINLAND Tel +358-2-8372 31 Fax +358-2-8372 3709 Working Report 2006-43 Depositional History and Tectonic Regimes within and in the Margins of the Fennoscandian Shield During the Last 1300 Million Years Seppo Paulamäki Aimo Kuivamäki Geological Survey of Finland May 2006 Base maps: ©National Land Survey, permission 41/MYY/06 Working Reports contain information on work in progress or pending completion. The conclusions and viewpoints presented in the report are those of author(s) and do not necessarily coincide with those of Posiva. ABSTRACT This report is a literature review, which describes the occurrences of Meso- and Neoproterozoic and Phanerozoic sedimentary rocks in Finland and their depositional history The report also summarizes the tectonic and magmatic events within and in the margins of the Fennoscandian Shield during the last 1200 - 1300 million years. Mesoproterozoic (Middle Riphean) and Neoproterozoic (Late Vendian) sandstones and siltstones are presently found only in some tectonically protected basins, e.g., Satakunta and Muhos grabens, Bothnian Sea basin and Bothnian Bay basin, or in the impact structures, but they may have originally distributed over a much larger area. During the Lower and Middle Cambrian, arenaceous and argillaceous sediments were probably deposited in most of the western, southern and central Finland. During the Ordovician, carbonates were deposited in an epicontinental sea with repeated transgressions and regressions. In several occasions, the Bothnian Sea and Åland Sea basins, as well as southern and south-western Finland were covered by the sea, and in the Middle Ordovician, the sea reached as far as central Finland.

  • The Influence of Crustal Properties on Patterns of Quaternary Fluvial
    quaternary Review The Influence of Crustal Properties on Patterns of Quaternary Fluvial Stratigraphy in Eurasia Tuncer Demir 1, Rob Westaway 2 and David Bridgland 3,* 1 Department of Geography, Akdeniz University, 07070 Konyaaltı/Antalya, Turkey; [email protected] 2 School of Engineering, University of Glasgow, Glasgow G12 8QQ, UK; [email protected] 3 Department of Geography, Durham University, Durham DH1 3LE, UK * Correspondence: [email protected] Academic Editors: Xianyan Wang, Jef Vandenberghe and Valentí Rull Received: 3 August 2018; Accepted: 19 November 2018; Published: 5 December 2018 Abstract: Compilation of empirical data on river-terrace sequences from across Eurasia during successive International Geoscience Programme (IGCP) projects revealed marked contrasts between the records from different crustal provinces, notably between the East European Platform (EEP) and the Caledonian/Variscan/Alpine provinces of western/central Europe. Well-developed terrace staircases, often indicative of hundreds of metres of Late Cenozoic uplift/fluvial incision, are preserved in many parts of the European continent, especially westward of the EEP. In contrast, rivers within the EEP have extensive sedimentary archives that are not preserved as terrace staircases; instead, they form sets of laterally accreted sediment packages, never more than a few tens of metres above or below modern river level. There are parallels in Asia, albeit that the crust of the Asian continent has a greater proportion of tectonically active zones, at one extreme, and stable platforms/cratons at the other. The observed patterns point strongly to the mobility of lower-crustal material within younger provinces, where the continental crust is significantly hotter, as a key part of the mechanism driving the progressive uplift that has led to valley incision and the formation of river terraces: a process of erosional isostasy with lower-crustal flow as a positive-feedback driver.

  • The Geological History of the Baltic Sea a Review of the Literature and Investigation Tools
    Authors: Monica Beckholmen Sven A Tirén Research 2009:21The geological history of the Baltic Sea a review of the literature and investigation tools Report number: 2009:21 ISSN: 2000-0456 Available at www.stralsakerhetsmyndigheten.se Title: The geological history of the Baltic Sea a review of the literature and investigation tools. Report number: 2009:17. Authors: Monica Beckholmen ovh Sven A Tirén. Geosigma AB, Uppsala. Date: September 2008 This report concerns a study which has been conducted for the Swedish Radiation Safety Authority, SSM. The conclusions and viewpoints pre- sented in the report are those of the author/authors and do not neces- sarily coincide with those of the SSM. Background The bedrock in Sweden mainly comprises Proterozoic magmatic and metamorphic rocks older than a billion or one and a half billion years with few easily distinguished testimonies for the younger history. For construction of a geological repository for deposition of nuclear waste it is important to understand the late, brittle, geological events to be able to estimate its influence and consequences for the repository. Purpose The purpose of the current project is to compile published data related to the geological history of the Baltic Basin. The intention of the study is to contribute to the understanding and characterization of earlier and on-going and bedrock deformation in coastal areas outside Forsmark and Laxemar where the Swedish Nuclear Waste Management Co (SKB) recently has finished site investigations for a repository for spent nuclear fuel. Of special interest are structures with evident indications of late bedrock movements where also future movements cannot be excluded.

  • Upper Ordovician Conodonts Kom Bornholm and Possible Migration
    Upper Ordovician conodonts fromBornholm and possible migration routes in the Palaeotethys Ocean SV END STOUGE & JAN AUDUN RASMUSSEN Stouge, S. & Rasmussen, J. A: Upper Ordovician conodonts from Bornholma nd possible migration routes in the Palaeotethys Ocean. Bulletin of the Geological Society of Denmark. vol. 43, pp. 54-67. Copenhagen 1996-07-14. https://doi.org/10.37570/bgsd-1996-43-07 Upper Ordovician conodonts from the Dicellograptus Shale Formation on Bornholm are recorded from the base of the Pleurograptus linearis graptolite Zone in the Vasegaardian Stage of the Harjuan Series (Upper Ordovician in Balto­scandic chronostratigraphy ). The conodont fauna includes Hamarodus europaeus, Protopanderodus liripipus, Scabbardella altipes andPeriodon grandis. Additional uncommonly encountered elements are referred to Eocarniodus gracilis?, Coelo­cerodontus? sp. A, new genus A sp. A and gen. indet. et sp. indet. The faunal composition is indicative of cool deep water to temperate shallow open marine conditions. TheHamarodus conodont fauna of thePleurograptuslinearis graptolite Zone is separated from the Dicellograptus clingani graptolite Zone by a hiatus. This hiatus is recognised along the north-western margins of the Baltica, Avalonia and Gondwana palaeocontinents and it is called the Vim-Harju regressive event (VHRE).
