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...

The handbook on lithiasis edited by Kurt Boshamer and originally brought out in 1961 was for more than two decades the standard work in this field for researchers and clinicians alike. However, our knowl edge of urolithiasis has been increased so enormously - by worldwide interdisciplinary research into the genesis of urinary calculi, by the new treatment possibilities opened up principally by advances in tech nology, and by the success achieved in prevention of recurrence - that it is almost impossible to take in all the relevant journal articles, books chapters, monographs, and proceedings....

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...
