Описание: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 178.
Hydrothermal systems at oceanic spreading centers reflect the complex interactions among transport, cooling and crystallization of magma, fluid circulation in the crust, tectonic processes, water-rock interaction, and the utilization of hydrothermal fluids as a metabolic energy source by microbial and macro-biological ecosystems. The development of mathematical and numerical models that address these complex linkages is a fundamental part the RIDGE 2000 program that attempts to quantify and model the transfer of heat and chemicals from "mantle to microbes" at oceanic ridges.
This volume presents the first "state of the art" picture of model development in this context. The most outstanding feature of this volume is its emphasis on mathematical and numerical modeling of a broad array of hydrothermal processes associated with oceanic spreading centers. By examining the state of model development in one volume, both cross-fertilization of ideas and integration across the disparate disciplines that study seafloor hydrothermal systems is facilitated.
Students and scientists with an interest in oceanic spreading centers in general and more specifically in ridge hydrothermal processes will find this volume to be an up-to-date and indispensable resource.

Описание: This volume presents an exhaustive overview of major orebodiesand mineral deposits of North Africa. It is intended both for academicresearchers and especially for exploration geologists interested in mineralexploration in the northern part of the African continent. Recent changes inthe mining laws of most countries in this region have encouraged internationalmining companies to invest in local mineral industries. Accordingly, thisvolume will be very useful for these professionals, as well as for researchersin the field of economic geology.
Описание: This volume synthesizes the relevant data that is fundamental to our understanding of trace metal biogeochemistry and the ecology of biological communities of deep-sea vent systems. It presents the combined results of biological and geochemical research and analyzes the microdistribution of animals and the spatial structure of vent communities. Careful consideration is given to the export of iron and other trace metals from hydrothermal vents. The environmental conditions to be found in deep-sea hydrothermal community habitats, along with the trace metal behavior in biotope water are characterized and the sources and forms of trace metals taken up by dominant hydrothermal vent animals are discussed. Special attention is paid to the poorly investigated deep biosphere of the sub-seafloor igneous crust. The book is illustrated with a wealth of exceptional deep-sea photos taken by the manned submersible “Mir”, and a dedicated chapter focuses on the role of deep manned submersibles in ocean research. The book will be of interest to researchers and students in the fields of oceanography, geochemistry, biology, the environmental sciences and marine ecology.

Описание: Research of the origins of life in connection with a marine environment started at the end of the seventies, when the `black smokers` in the Pacific were discovered and the Red Sea deep hydrothermal brines were found to be a fruitful environment for abiotic synthesis of life precursors.

Описание: Results of selected projects on Exploration R & D, one of the major research areas implemented by the Commission of European Communities in Brussels on the subject of mineral raw materials, are presented on an international basis. The question of possible application to exploration methodology is explored in several papers.

Relative va1ue of the contributions of Ni+Co, Cu and PGE to the mag- matic su1fide deposits listed in Table 1. 1 sulfide deposits are closely related to bodies of mafic or ultramafic rock, and the most convenient way in which to consider them is in terms of the type of magma responsible for the rocks with which they are associated. Typically the type of magma involved bears a close relationship to the tec- tonic setting within which it was emplaced. The locations of important deposits, both Ni-Cu dominant and PGE dominant, are shown in Fig. 1. 2. Considering first Ni-Cu deposits, these are further divided into six classes (Table 1. 2) on the basis of their associated magma type. Class NC- 1 (Chap. 3) comprises those related to komatiitic magmatism. Currently known deposits fall into two sub-classes, those related to Archean komatiites ( e. g. the deposits of Western Australia, Zimbabwe and the Abitibi belt of Canada) and those related to Proterozoic komatiites (e. g. those ofthe Raglau and Thompson belts which arebothin Canada)l.
Описание: 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.
