Abstract
Book synopsis: This book offers invited papers of the international workshop organized in Irkutsk and Naples. Alkaline rocks represent unique formations on the Earth. They are associated with large Nb, Ta, Zr, Y, TR, Cu and P deposits, gemstones of charoite, Cr-diopside, dianite. In Australia diamonds are recovered in lamproites. The complicated processes of their formation provoked scientific disputes still going on. The newly developed analytical methods and techniques provided abundant information on the composition of alkaline rocks. The data on geochemistry of isotopes confirm the evidence on the mantle - -ources of the substance of alkaline rocks. Features of mineral parageneses and origin of mantle rocks can help in interpreting the deep-seated geodynamics of the Earth. These papers view the features of alkaline, carbonatite and kimberlite magmatism. They also disclose the influence of the fluid on the thermal regime of mantle plumes. They discuss thermodynamic analysis of magnetite+titanite+ clinopyroxene equilibria in apatite-bearing intrusion of the Khibina alkaline complex, geochemistry of the dyke alkaline complex of the Kola Peninsula. They show geologic and petrologic characteristics of alkaline rocks of Italy. As to the kimberlites are concerned the papers consider variations of picroilmenite composition from many kimberlite pipes of Siberia; discuss the behavior of some minerals-indicators in kimberlites, mantle xenoliths from Nyurba pipe. The melted inclusions in olivines demonstrate mineral called rhönite and some papers give thermodynamic parameters of renite formation. The articles give grounds for distinguishing formation types of lamproites and give types of their mantle sources. ASM diagrams are suggested to be used for genetic analysis of magmatic rock series. The book might present interest to specialists involved in petrological and geochemical investigations as well as those studying deep alkaline and kimberlite magmatism, students and teaching staff of universities.
