Evolution of Magmatic and Diamond-Forming Systems of the Earth's Lower Mantle

This book sheds valuable new light on the genetic mineralogy of lower-mantle diamonds and syngenetic minerals. It presents groundbreaking experimental results revealing the melting relations of ultrabasic and basic associations and a physicochemical peritectic mechanism of their evolution.

The experimental investigations included here reveal the key multicomponent, multiphase oxide-silicate-carbonate-carbon parental media for lower-mantle diamonds and syngenetic minerals. Consequently, readers will find extensive information on the diamond-parental oxide-silicate-carbonate-carbon melts-solutions that supplement the general features of lower-mantle diamond genesis and the most efficient ultrabasic-basic evolution. The experimental results on physicochemical aspects, combined with analytical mineralogy data, make it possible to create a generalized composition diagram of the diamond-parental melts-solutions, there by completing the mantle-carbonatite concept for the genesis of lower-mantle diamonds and syngenetic minerals.

This book addresses the needs of all researchers studying the Earth's deepest structure, super-deep mineral formation including diamonds, and magmatic evolution.

Summarizes groundbreaking experimental results revealing the melting relations for lower-mantle systems and analytical data for mineral inclusions in super-deep diamonds Explains the physicochemical peritectic mechanisms of ultrabasic-basic evolution for both the lower-mantle native magmatic and diamond-forming systems Enriches readers' understanding of the key role of carbonate components in diamond-parental media Substantiates the mantle-carbonatite concept for the genesis of lower-mantle diamonds and syngenetic minerals
