Marc Notes: Based on the NATO Advanced Research Workshop on 'Improvement of Joint Interpretation of Geophysical and Geological Data with Particular Reference to the Lithosphere Structure and Evolution of the Adriatic Microplate and Adjacent Regions', Gradisca d'Isonzo, Italy, October 1-9, 1987 and February 22-23, 1988; Published in cooperation with NATO Scientific Affairs Division.; Includes bibliographical references. Table of Contents: Computers and Personal Computers in Geophysics.- Interpretation of Gravimetric and Magnetic Data: a short Review.- An Introduction to Geophysical Databases and two Examples of the Use for Crustal Studies.- Geophysical and Geological Parameters being important for Modelling.- Seismic Standard Software in Refraction and Wide-angle Applications.- Fine Modeling of the Elastic and Anelastic Parameters of the Earth s Crust by means of Complete Synthetic Seismograms.- A seismic Tomography Program for Geological Investigations.- Compressional Tectonics and the Balancing of Crustal Cross Sections.- Enhanced Interpretation of Crustal Sections with the Thrustbelt program.- Isostatic Compensation of Balanced Cross Sections.- CROP-ECORS Activity in the Western Alps.- A seismic Refraction Line between the Ligurian Sea and the southern Alps Evidences for crustal doubling.- The Fragmented Lithosphere of the Northwestern Adriatic Microplate as Revealed by Deep Seismic Sounding."Publisher Marketing: The contributions published in this volume are the re sults of the NATO Advanced Research Workshop "Improvement of Joint Interpretation of Geophysical and Geological Data," which took place in Gradisca d'Isonzo in October 1987 and February 1988. Modern computer techniques were applied for geoscien tific studies in a new dimension. 45 scientists from 7 Euro pean countries, Canada and the united states of America par ticipated in the workshop. Interactive discussions and modeling improved the understanding of the very complex structure of the investigated area. We thank all contributors, but especially those pub lishing in this volume, for their active participation to ensure the success of the meetings. Not to forget to mention the groups of assistants from the Istituto di Minere e Geo fisica Applicata of the University of Trieste and from the Institute of Geophysics of the Freie Universitat Berlin. Many thanks for their help around the clock. However, a major prerequisite for this success was given by the hospitality of the international Centre for Applied Sciences (ICAS) in the wonderful restored ancient pallazzi Torriani and Pretuna of the town of Gradisca d'Isonzo. Thus, we are thankful to the president of ICAS, Dr. H. R. Dahlafi, and to the town of Gradisca d'Isonzo, especially to the mayor, Signore Travan. The studies carried out in Gradisca d'Isonzo had been supported by a grant of the NATO Scientific Affairs Division and we express our thanks to Dr. L. da Cunha as a steady partner in the background."
