Description: This volume contains the contributions of a conference dealing with the consequences of the European Monetary Union for the macroeconometric modelling of the Euro area, which took place in Essen in 2000. At the end of the conference the participants were convinced that the discussions including a great variety of theoretical, methodical and factual aspects from the producers' as well as the consumers' perspective will not fail to have a certain impact on the future development of macroeconometric modelling in the Euro area. Once more it became clear, however, that an ideal way to a solution of the problems is still not in sight. The future development will be characterized by a plurality of approaches and models. Thus trends continue which have had a more or less strong, durable or temporary influence on the model landscape since the emergence of the monetarist revolution, the ""rational expectations"" or the ""real business cycle""-models. We are still at the beginning of the theoretical and empirical exploration of the macroeconomic development of the Euro area, it is not always clearly perceptible what is transitory and what is permanent, and this openness should facilitate the reception of the experiences and results which have been presented. The idea for this event was developed in the course of the Project LINK. One of the highlights of the conference was the participation of the nobel prize winner Professor Dr. Lawrence Klein - pioneer and Nestor of macroeconometric modelling - who, as his contribution shows, is following up the creation of the European Monetary Union with critical interest.

Description: Palagonitized sideromelane from submarine volcaniclastic, seafloor volcanic, marine phreatomagmatic, lacustine phreatomagmatic, and subglacial volcanic settings was investigated using in situ microanalysis to test if palagonite composition and texture are related to depositional environment. Palagonitization extent varies linearly and inversely with original sample porosity, suggesting that porosity is a controlling factor of palagonitization. Water absorbance of reflected infrared light varies linearly with water content derived from electron microprobe totals. Palagonite water content has a linear, inverse relationship to palagonitization extent. REEs are immobile during palagonitization, so they can be used to construct isocon diagrams for estimating major-element concentration changes. Major-element and overall mass changes during palagonitization vary widely (particularly for FeO and TiO2) and indicate that palagonitization cannot be an isovolumetric process. These parameters depend strongly on original sideromelane composition, thus requiring composition to be taken into account when performing global oceanic cation flux calculations. Subalkaline sideromelane dissolves much more rapidly than alkaline sideromelane during palagonitization. Two styles of palagonitization, burial-diagenesis (relatively long-duration, low water/rock; passive fluid circulation) and hydrothermal (relatively short-duration, high water/rock; hydrothermal fluid circulation), are recognized. Observed palagonite REE concentration gradients indicate that sideromelane dissolution must continue in the zone behind the advancing palagonitization front. MgO was found to be highly mobile during palagonitization. Observed palagonite MgO gradients are not developed during sideromelane dissolution, but instead record initiation of syn- and/or post-palagonitization conversion of the gel-palagonite layer to a phyllosillicate layer, consistent with evolution of sideromelane alteration layers toward equilibrium with the solution.
