Supergene and Surficial Ore Deposits; Textures and Fabrics is a collection of papers that deals with economic geological deposits, particularly as endogenic type, or as an integral part of their geological environment. One paper explores the possibility that the evolution of ores of sedimentary affiliation or of sedimentary rocks and their chemistry during geologic history can be a product of the evolution of the outer spheres of the earth combined with a cycling phenomena that proceeds in a spiral way. Another paper discusses the role of climate on a large range of depositional environments through mobilization, both by chemical and physical events, of metal-ions. Mobilization can also occur by controlled deposition and enrichment of the "mobilized" ions in a certain sedimentary environment. Various depositions occur in different climates, for example, bauxites, requiring higher precipitation levels, form in humid zones. One paper points that ore-mineral accumulations controlled by descending supergene solutions play a significant role in ore-mineral depositions. The collection is beneficial to geologists, industrial chemists, researchers, technical designers, and engineers whose works are related with ore deposits and mining.

Handbook of Exploration Geochemistry, Volume 3: Rock Geochemistry in Mineral Exploration focuses on the application of rock geochemistry in mineral exploration, including deposits of plutonic association, volcanic and sedimentary association, and sequence of geochemical exploration. The publication first elaborates on geochemistry in the exploration sequence, crustal abundance, geochemical behavior of elements, and problems of sampling and recognition of geochemical anomalies. Discussions focus on population partition, spatial distribution of data, abundance of elements, classification and geochemical behavior of elements, principles underlying geochemical exploration, sequence of geochemical exploration, and main types of geochemical surveys. The text then takes a look at regional scale exploration for deposits of plutonic association; regional scale exploration for vein and replacement deposits; and regional scale exploration for stratiform deposits of volcanic and sedimentary association. The book ponders on the synthesis of geochemical responses and operational conclusions, local and mine scale exploration for stratiform deposits of volcanic and sedimentary association in Cyprus, Turkey, and Oceania, New Brunswick deposits, and Precambrian, Proterozoic, and Kuroko deposits. The text is a valuable reference for researchers interested in the application of rock geochemistry in mineral exploration.

World Mineral Supplies: Assessment and Perspective examines some of the issues in the debate about whether there is an impending global shortage of mineral resources and whether technology and exploration can meet the needs of a rapidly growing rate of mineral consumption in the world. The geologic and economic factors that determine the demand for and the availability and distribution of mineral resources and reserves are discussed, and the future of mineral resource supplies is considered. Comprised of 14 chapters, this volume places emphasis on the technical problems of assuring adequate mineral supplies for the future. The discussion begins by analyzing the complexities and confusion that color much of the discussion about the size and adequacy of world mineral supplies, focusing on the importance of distinguishing between "resources" and "reserves". The next chapter deals with the creation of reserves from resources as a function of price, cost, ore grade, and technology. Subsequent chapters explore the physical and chemical factors that determine the absolute abundance and the actual availability and distribution of resources; the actual geographic distribution among countries of mineral supply and demand; and trends in energy consumption and supply. Conservation of minerals and of the environment and mineral exploration and technical cooperation in developing countries are also treated in considerable detail, along with deep mining techniques and UNDP-assisted projects in geology and mineral resources. This book will be of interest to economists, social scientists, geologists, mining engineers, and mineral technologists.
