The monograph considers petrology and geochemistry of recent volcanics of Eastern Volcanic Zone of Kamchatka and post-eruptive processes of volcanogenic and geothermal lithogenesis and ore formation. The source of ore material is endogenous. It is formed at the last stage of differentiation of initial basaltic melt.
For volcanologysts, litologysts and geologists of wide profile.

В работе показан характер мобилизации и концентрации рудных компонентов в условиях проявления современных вулканических процессов. Изложены результаты исследований, проведенных на действующих вулканах главным образом Курильских островов и Индонезии.

This book is the first work that provides the ultimate data about chemical composition of the Kamchatka Quaternary andesites. Besides the book provides data about a phase analysis of andesites, geochemical composition, REE composition and isotopic analysis of strontium, neodymium and oxygen. The analyses are prominent for their stratification and accurate geological positioning. This allows understanding how the geological events alternated. The paper is focused on the petrogenetic peculiarities of tholeiitic (the 1st type of mantle genesis) and calc-alkali (the 2nd type of mantle-crust genesis) andesites. The book stresses that petrochemical, petrological and isotopic-geochemical correlators play a great role in distinguishing of those two types of andesites. On the basis of petrochemical database we distinguished three trends of the volcanites differentiation: stable, unstable and intermediate. These trends are supposed to be used for the determination of the volcanic activity character and types of the volcanic eruptions.
This book will be helpful as a reference guide to volcanologists, petrographers, geochemists and geologists, to those who study the genesis of volcanic rocks.
