Zur 7. Jahrestagung der Gesellschaft fUr Informatik hatte der Pro- grarnrnausschuB urn die Einreichung von Ubersichts- und Spezialvortra- gen aus allen Gebieten der Inforrnatik gebeten. Vortrage Uber Ent- wicklungs- und Benutzungserfahrungen bei Anwendungssystemen solI ten besondere Beachtung finden. (Darnit waren aber nicht Reklarnevortrage im Prospektstil gemeint.) Dem PrograrnrnausschuB wurden 54 Manuskripte vorgelegt, von denen ei- nige sich nur unwesentlich von bereits bei anderen Tagungen ver- 6ffentlichten unterschieden und somit ausgesondert werden muBten. Aufgrund der Beurteilung durch die Rezensenten und eigener LektUre hat der PrograrnrnausschuB schlieBlich 13 Vortrage ausgewahlt, die in diesem Tagungsband zusarnrnengefaBt sind. Das Ziel der Gesellschaft fUr Informatik, die Anwender in eben so starkem MaBe anzusprechen wie die Hochschulangeh6rigen, wurde dabei wiederum nur urn ein sehr kleines StUck vorangebracht. Die Ubersetzung praktisch relevanter Forschungsergebnisse in eine dem Anwender verstandliche Sprache, wird eine vordringliche Aufgabe zukUnftiger Jahrestagungen sein.Bei den Themen, die fUr die Hauptvortrage und fUr die Podiumsdis- kussion gewahlt wurden, ist ebenfalls versucht worden, aktuelle Themen zu finden, die sowohl fUr den Hochschulbereich als auch fUr die Anwender von Bedeutung sind und damit die LUcke zwischen bei- den UberbrUcken helfen. Leider ist es zum ersten Mal nicht gelungen, die Hauptvortrage der eingeladenen Referenten mit in den Tagungsband aufzunehrnen. Der Wunsch, den Tagungsband bei Beginn der Tagung zu verteilen, ergab eine zu knappe Zeitspanne fUr die Hauptvortragenden, ihre Manu- skripte fertigzustellen.

The problem of time-and strata-bound formation of ore deposits has during the past decade become one of the most debated topics in cur rent international discussion. Due to the amazing results of modern mineral exploration and world-wide geophysical research, the mutual relationship between the complex geological history pf a crustal seg ment and the development of distinct metallogenic provinces (ore belts) has received much interest. Reviewing the earth's history in this light one can now recognize metallogenic epochs even of global range which document the existence of world-wide time-bound ore enrich ments. The knowledge of these metallogenetic processes has been growing step by step for several decades. It began with simple observations and sceptic interpretations, which at first threw heretical spot lights on to the edifices of the prevailing theories on granitic differentiation as the favoured source of ore deposits. It was obvious that the new ideas at first referred to ore enrichments in sedimentary sequences, nowadays summarized under the term strata-bound, and mainly interpreted as stratiform or sedimentary ore deposits. Moreover, the modern term "strata-bound" also includes ore mineralizations which are bound to distinct units of layered (intrusive or extrusive) igneous complexes as a general descriptive term without genetical restriction! Albert Maucher is one of the representatives of the initial era who discussed these genetical questions critically in the decade before the 2nd World War.

The research on mineral deposits and the exploration of new vast resources made exceptional progress worldwide during the last decades. At the same time, mining activity has shifted from the historical European centres to other continents. Even though the mineral pro- duction of the Alpine province has lost its significance as compared with other areas of the world in this century, striking ideas and theo- ries on the formation of mineral deposits originating from this domain have stimulated lively international discussion. This may be explained by the proximity of different peoples with varying geographical and intellectual backgrounds meeting in the Alpine region. Realizing this development some Italian colleagues, above all Remo Albertini and Guiliano Perna, initiated the (first) International Sym- posium on Mineral Deposits of the Alps in 1966. When I. ISMIDA won favorable attention, it was resolved to call further meetings at regular intervals. A different Alpine country was host and organizer each time. As a first summary of the historical development, we give a short record of previous meetings: I. ISMIDA Sept. 11-18,1966, held at Passo della Mendola/Italy II. ISM IDA Oct.4-6, 1971,heldatBled/Yugoslavia III. ISMIDA Oct. 3-7, 1977, held at Leoben/ Austria IV. ISMIDA Oct. 5-10,1981, held at Berchtesgaden/Bavaria, FRG The present volume contains the greater number of papers pre- sented at the Fourth International Symposium on Mineral Deposits of the Alps, held at Berchtesgaden (Bavaria), Federal Republic of Ger- many, in 1981.
