Book Description
This proceedings book represents a collection of conference papers examining the fundamental problems of deep magmatism.Enriched mantle reservoirs can be the source of the most massive apatite and rare metal deposits. Additionally, this book also presents some of the characteristics of kimberlites' composition from the deep Yubileinaya pipe and the mineralogical features of the Nakyn kimberlite field (Yakutia) and the crystallochemical features of rare and complex silicates from charoite rocks of the deep Murunskii massif in South Africa and the comendites of Mongolia.

Book Description
Phoscorites are dark, often very handsome, sometimes economically valuable, magnetite-apatite-silicate rocks, almost always associated with carbonatite. They are key to understanding the longstanding question of how carbonate and carbonate-bearing magmas rise to the crust and the Earths surface. Despite this, they have been given little attention; a search on geological literature databases will produce thousands of references to carbonatite (up to 4125 on Georef) but not more than thirty references to phoscorite. This book goes some way to redress this balance. Over recent years many European and North American scientists have studied Kola rocks in collaboration with Russian colleagues. The idea for this book came from one such project funded by the European organisation, INTAS (Grant No 97-0722). The Kola Peninsula is one of the outstanding areas in the World for the concentration and economic importance of alkaline rocks. However, Russian work on the Kola complexes is still relatively unknown and a particular aim of this book, as well as presenting current research, is to make this knowledge accessible to English language readers. A large exploration programme on Kola alkaline rocks was active from 1950 to 1990 and involved teams of geologists who studied many kilometres of drill core and carried out detailed mineralogical and petrological studies.

Book Description
This book presents an extensive overview of literature published globally in the last decades on REE distribution in minor and accessory minerals from various types of ultramafic, mafic, and other plutonic rocks. It is a continuation of the author’s work published in 2010: Rare Earth Elements in Ultramafic and Mafic Rocks and their Minerals. Main Types of Rocks. Rock-Forming Minerals. The analytical database created includes over 900 analyses of minerals, including garnets (341), chrome-spinels (38), ilmenites (160), zircons (210), apatites (62), titanites (51), perovskites (46) and micas (35). The book offers a brief historical background on REE distribution for each of the minerals and analytical methods for their determination; further, the main features of concentration of these impurities in the samples of different rocks and their manifestations are described and the regularities of REE distribution between coexisting phases, including parent melts, systematized available estimates of distribution coefficients are considered. REE isomorphism in these minerals is discussed as well as the possibilities of using data on REE distribution as typomorphic signs of determining the crystallization conditions of minerals. The numerous analyses of REE presented in this book can be used as reference data. Finally, there is an additional chapter on a new problem: the study of geochemical relations between REE and platinum group elements. As an overview of modern data on the geochemistry of REE in minor and accessory minerals from rocks of mafic-ultramafic complexes and as a reference book, this work will be of interest to a wide range of specialists studying petrology and geochemistry of products of ultramafic and mafic magmatism, including ore mineralization, as well as for graduate and undergraduate university students in geology departments.
