    Notes: Zusammenfassung Petrographische und chemische Untersuchungen an Dioriten und Graniten des Kyffhäuser und von Dessau lassen eine Ichor-Metamorphose, d. h. eine Alkali-Metasomatose von den Porenräumen aus, erkennen. In den metamorph-metablastischen Granitabkömmlingen wird die Ichor-Metamorphose deutlich an einer Glomeroblastenbildung und einer erneuten körnigen Texturentwicklung. Diese beweist eine Zufuhr von Albitmolekül. Sie wird in dem metamorph-metablastischen dioritischen Gestein neben der Verdrängung der primären Plagioklase aus der Alkalisierung und Enteisenung der Hornblende ersichtlich. Die magmatischen Ausgangsgesteine: Diorit, Quarzdiorit, Biotitdiorit, Gabbrodiorit (?) und Hornblendegabbro zeigen neben der Alkalisierung eine Muskovitisierung der basischen Plagioklase und eine Biotitisierung der Hornblende, woraus eine Zufuhr an Kali hervorgeht. Diese Stadien der Metamorphose durchlaufen den tektonischen Raum von der Grenze metamorph-nichtmetamorph bis hinab zur Grenze metamorph-magmatisch (Erdmannsdörffer) und rind in der Mitteldeutschen Schwelle zuerst aus dem tiefsten Stockwerk, im Südwesten im Odenwald-Spessart (Erdmannsdörffer) und nunmehr auch aus ihrer äußersten Haube erkannt worden, wo die Schwelle unter die Phyllithülle hinabtaucht.

    Notes: Zusammenfassung Die Existenz des Leverrierit als selbständiges Mineral wird mineralogisch (A. Schüller) und chemisch (H. Grassmann) nachgewiesen. Zusammenfassend seien die Eigenschaften des Leverrierit und des mit ihm verwechselten Kaolinit gegenübergestellt (Tabelle 4).

    Notes: Zusammenfassung Es werden Tonsteine beschrieben, die als „biochemische” Sedimente im Steinkohlenmoor gebildet wurden. Die bisherige Deutung, solche Tonsteine seien ehemalige vulkanische Aschentuffe, wird als zur Zeit petrographisch unbegründet abgelehnt.

    Description: Within the wave-dominated and high-energy depositional environment of the hyper-arid Namibian coast, lagoons and related saltpans represent one of the few regional settings in which sediments originating from both marine and terrestrial sources can accumulate under sheltered conditions. This allows for an approximately continuous depositional record of mid to late Holocene coastal evolution. For this paleoenvironmental reconstruction, 26 sediment cores from six coastal (paleo-)lagoons were taken and investigated along a 430 km-long latitudinal gradient. Based on 56 age determinations of sediments and shell material, the initial formation of the studied lagoons can be dated back to 6.0–5.3 cal kyr BP. The sediment cores present different types of lithoclastic sediments which can be assigned to five sedimentary facies ranging from sand spit sediments rich in shell material to eolian dune sands and evaporites. From these cores, 221 samples of macrobenthic faunal material have been collected and determined to possess 46 shallow marine species. Biogeographic analyses have resulted in the identification of 10 (sub-)tropical warm water species that are not part of the regional benthic fauna in the present upwelling system. Age determinations of the shell material revealed four phases of biogeographic range expansion/shift into the study area, at 5.3 cal kyr BP, 2.8 cal kyr BP, 1.2–0.9 cal kyr BP, and 0.36–0.12 cal kyr BP from both the northern tropical Angola Current as well as from the southern subtropical Agulhas Current. The combination of datasets from this study with published datasets of regional sea-level fluctuations and upwelling intensities presents an apparent correlation between both processes and presumably an additional linkage to the ENSO and Benguela Niño variability.

    Description: Disaster Risk Reduction (DRR), Disaster Risk Management (DRM), and Climate Change Adaptation (CCA) involve a variety of stakeholders with different backgrounds, organizational frameworks, divergent concerns, and sometimes competing agendas. This requires forums where such groups can meet in order to enhance understanding, reconcile different views, and potentially assist each other in meeting their respective goals. One means of establishing such an exchange involves serious games. During the ESPREssO (Enhancing Synergies for disaster Prevention in the European Union) project, three such games, referred to as RAMSETE (Risk Assessment Model Simulation for Emergency Training Exercise), were developed. They were based on table-top, role-playing, scenario-based exercises, and their purpose was for stakeholder information elicitation about policy issues related to DRR, DRM, and CCA. Participants in the exercises were assigned roles where they interacted and negotiated in order to deal with the presented scenarios. The scenarios were primarily concerned with selecting an optimal set of policies to deal best with the issue in question. The games, while sometimes including an operational element, were meant to examine the motivations behind the decisions made, rather than to test or to train in response protocols. The participants in general found the games to be useful for framing discussions about complex issues, while their problem-solving character was appreciated and enjoyed. Such games allow stakeholders to openly discuss and challenge ideas, policies, and processes in a manner they would not normally do in their daily activities, with other professionals who they would not necessarily be in frequent contact with.

    Description: The ESPREssO Project set out to propose ways to inform more coherent national and European approaches on Disaster Risk Reduction (DRR) and Climate Change Adaptation (CCA). A critical step in this process is the identification of existing barriers to effective collaboration, finding new areas of common ground, and ways to enhance co-operation with regards to CCA and DRR policymaking in Europe. This is particularly important considering the potential relationships between CCA and DRR activities at the regional, national, European and global levels. Serious games have emerged as a valuable tool to communicate information and catalyse discussion in many policy arenas. The games have the power to inform, mainly by exposing strengths and weaknesses of a system but not necessarily create policy choices. This paper presents the development process and rationale behind creation of RAMSETE I, a serious game developed by and for the ESPREssO Project to elicit information from its stakeholders in aiming to inform synergies between CCA and DRR sectors. The results assess its application as a device to frame discussions during an international Think Tank workshop. The serious game focused on three particular aspects of CCA and DRR policy interactions: (1) separation of administrative responsibilities and the use of different terminology, (2) the ongoing competition for funding and political will as well as (3) difficulties regarding the top-down implementation of policies. The rules and design process are presented briefly, before going in-depth into the information gleaned during its application in the workshop.
