The present volume Stratabound Ore Deposits in the Andes has its roots in an international seminar on stratabound ore deposits which took place in September 1986 in Cusco, Peru, sponsored by Multi ciencias (Peru) and UNESCO. During this seminar it became clear that the amount and quality of research done on stratabound ore deposits in the Andes required a synthesis. Researchers in industry and government as well as in academia, including many which had participated at the Cusco Seminar, were invited to contribute. The answer was extremely positive, confirming the idea that a book expressing the state of the art of the study of stratabound ore deposits in the Andes was long overdue. As editors we sought to give maximum coverage to the present knowledge, yet keeping the length, and thereby the price, within rea sonable limits. The book contains three types of contributions. In the first part the reader will find review papers focusing on ( 1) the geologic framework (Frutos), (2) the metallogenesis in Andean countries including also types of deposits differing from those of stratabound nature (Cardozo and Cedillo, Oyarzun), and (3) an in troductory overview of the stratabound ore deposits in the Andes, emphasizing their geotectonic position as a classification tool (Font bote).

This volume gives an overview of the geotectonic evolution of the Central Andes. The contributions cover the whole spectrum of geoscientific research: geology, petrology, geochemistry, geophysics and geomorphology. They deal with the period from late Precambrium up to the youngest phenomena in the Quaternary. The book is of value for regional geologists as well as for scientists interested in orogenic processes related to active continental margins.

Translated from Russian, this text looks at the development of the earth's crust in the Palaeozoic period and starts from the Vendian to the Late Cambrian period. Moving on to include Ordovician to the mature stage of Caledonian and initial stage of development of Hercynian mobile belts; Silurian-Early Devonian. The completion of development of the Caledonian and early, mature and end stages of the Hercynian mobile belts; the birth of Cimmerian mobile belts and ending with the Palaeozoic.

This volume summarizes the current state of knowledge of each of the main sectors of the basin. After reconstructing Permian-Triassic Gondwanaland, authors from South America, South Africa, Antarctica, and Australia illustrate the relevant geology of each sector in maps and time-space diagrams under
