This book (Special Issue) presents the geological environment, physical/chemical properties, and crystallographic data for two new minerals associated with chromitites from the Othrys ophiolite complex: Eliopoulosite, V7S8/IMA2019-96, and Grammatikopoulosite, NiVP/IMA2019-090. The distribution, mineralogy, and field relationships of PGE-enriched ores, which are important for our understanding of the metallogenic controls on the concentration of PGE and their exploration, are addressed in papers, providing (a) the first detailed data on the chromitites and platinum-group elements (PGE) mineralization from Ulan-Sar’dag ophiolite, Central Asian Fold Belt/East Sayan, Russia, (b) peculiarities on the distribution of PGE in arsenopyrites and pyrites from the Natalkinskoe gold ore deposit, NE Russia, and (c) the occurrence of zoned laurite found in the Merensky Reef of the Bushveld layered intrusion, South Africa, characterized by textural/compositional features suggesting “hydrothermal” origin. Two papers deal with (a) the rare earth element (REE) distribution in various mineral deposits of Sweden, obtained during the EURARE project, and their application to the exploration of REE and (b) the optimization of the beneficiation process for the REE recovery from black sands. Five papers provide new data of genetic and exploration significance on trace elements, including REE and PGE in various ore-types, and factors controlling the Cr stable isotope (δ53Cr values) in chromitites from the Balkan peninsula.

The book (Special Issue) presents impressive new results related to a wide spectrum of occurrences of platinum-group minerals (PGM) and natural compounds enriched in platinum-group elements (PGE), which are associated with various complexes and deposits, such as Uralian-Alaskan-type complexes, layered intrusions and placers. The geographical locations of the involved deposits and complexes include, on a truly international scale, different areas of the Urals, Western and Eastern Sayans and Gornaya Shoria in Siberia, Southern Central Asian Orogenic Belt in China, Northern Michigan, USA, South Africa and Zimbabwe, etc. Of particular interest is the first description of a new species of PGM, thalhammerite (approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association), which is a new species of palladium-silver sulfobismuthide discovered in the Noril’sk region of Russia. Additionally, comprehensive reviews, on compositional variations in Pt–Fe alloy minerals and processes of transformations of PGM in exogenic environments, are presented which will also attract attention from international readers.

The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium and osmium. They are currently receiving world-wide attention as an attractive exploration target because they offer the dual attraction of rare, high value precious metals as well as major industrial applications. Platinum has aesthetic qualities, combined with a permanent lustre, which encourage its use in the manufacture of jewellery and, like gold, it also finds an investment role. Platinum, rhodium and palladium have important applications as catalysts, enabling petroleum and other fuels and chemicals to be produced efficiently from crude oil. This book gives a practical set of guidelines for implementing a programme of PGE exploration, detecting subtle indications of mineralization and assessing the economic potential of a group of mafic or ultramafic rocks. Background material is given on the economic and geological framework of the PGE in the first chapter, while theoretical aspects of magma chemistry are covered in the next three. Chapters 5 and 6 review current world-wide exploration activity within the context of available reserves of PGE, and in Chapter 7 factors which need to be considered in exploration for new deposits are outlined. The last chapter discusses evaluation guidelines. As the PGE are both costly and almost indestructible they are normally recycled; nevertheless, a substantial annual input of new metal is needed to replace process losses, to permit increases in capacity in the dependent industries and to provide for new uses. For example, a major new market for platinum will be created if the European Community countries are required to fit catalytic converters to new cars. At present, South Africa and the USSR are the sources of most of the western world's newly mined PGE, with virtually all the South African production derived from the Bushveld Complex. Much of the material presented in this book is based on the author's experience of these rocks, and emphasis is given to the dominant role played by magmatic sulphides as potent collectors of PGE. Consumers of minerals and metals, however, prefer to have a diversity of supply and a new PGE producer is therefore likely to attract a ready market. Not only does the book provide a wealth of practical information for mining geologists, it also contains much of interest to those in natural resource management and investment.

The chemistry of platinum group metals is a rapidly expanding commercially important field. It is dominated by the catalytic properties of the metals. They are useful in petrochemical and general chemical plants and are becoming increasingly important as autocatalysts for pollution control. The book covers recent developments in the chemistry of the six platinum group metals, namely, platinum, palladium, rhodium, iridium, ruthenium and osmium. The material falls into three broad areas. Firstly, the occurrence, extraction and use of the metals, especially in catalysis, electrochemistry, energy and electronics. Secondly, organometallic and homogeneous catalytic chemistry and last but not least coordination chemistry including biochemistry and cancer therapy. The work is aimed at scientists in universities and in industry using any of the six platinum group metals in research. It will be useful for those studying the compounds of the metals themselves, and those considering to use either the metals or their complexes and catalysts in their experimental work.

Raw materials have been essential in the development of all human societies through history and moving into a greener, more carbon-lean future we become increasingly reliant on access to a growing number of raw materials. Minerals for new technologies improving the quality of our lives and the environment are the building blocks of the new Green Stone Age. This Special Publication presents ongoing research and mapping programmes focusing on minerals needed for the transformation to greener societies. In addition to new exploration models and shared geological information on the different prospective currently mined areas, the notion of criticality in different countries is discussed and examples of ongoing national and cross-country research and mapping programmes are presented. In addition to the resource/reserve and technical-economic aspects, the social and environmental dimensions are also a focus in some of the contributions, as holistic approaches to the exploration and exploitation of critical minerals and materials are needed to fulfil the green transition and goals for the Green Stone Age.

The Geo-Platinum 87 Symposium, held at the Open University during April 1987, was designed as a forum for presentation of new research results on the occurrence, genesis, geochemistry, mineralogy and analysis of the platinum-group elements (PGE). With the support of the Open University and the Mineral Industry Research Organisation, the symposium was attended by 115 representatives of university departments, research institutions and members of the mining and mineral exploration industries. An introduction to the symposium was provided by two invited papers from C. J. Morrissey (Riofinex North) and C. R. N. Clark (Johnson Matthey) which were designed to give perspective to the goals of PGE research work. The first of these papers gave a provocative insight into the aims and objectives of an exploration manager, examining the influence of supply, demand and perceived world reserves on exploration strategy. The second invited paper gave a valuable view of the industrial uses, market trends and predicted changes in the commercial value of the platinum-group elements from the standpoint of a refining company and supplier. These invited papers are reproduced in this volume and are followed by twenty four full papers and twenty abstracts that reflect the wide range of research topics presented at the symposium.
