The book provides a systematic description of active volcanoes of Kamchatka — one of the most active volcanic regions of the world. Distribution, shape and activity of the volcanoes, their position in complex and long-lived volcanic centres, as well as their geologic structure and composition are presented.
The book is illustrated with colour maps, schemes, and sketches. Over 300 colour photographs show volcanic landscapes, diverse volcanic forms (cones, craters, lava flows, calderas, etc.) and various manifestations of post-volcanic activity (hydrotherms, famous Kamchatka geysers).
Concise, lavishly illustrated with colourful and high-quality photographs, the book makes an interesting and useful reading not only for specialists (volcanologists, geologists, geochemists, geophysicists, geographes, etc.) but for a bioad readership as well. The publication is unique and unparalleled in scientific literature. The text is presented in Russian and in English.
This monography is written by scientists from the Institute of volcanology, Far East Division, the Academy of Science of the USSR.

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.

Isotope-geochemical material for Pliocene-Quaternary volcanoes of the Kamchatka region is generalized on a cartographic basis. The Sr-isotope anomalies of moderate and elevated radiogenicity, geochemically confirmed, are spatially conjugated. This made it possible to interpret these anomalies not only as a reflection of mantle plume material in the composition of volcanic rocks, but also of its hybrid environment, as a consequence of plum-lithosphere remobilization. The presence of multi-directional geochemical trends made it possible to propose the concept of moving boundary values for the composition of indicator rocks of the intraplate type and adakites, which significantly expanded the possibilities of their diagnostics. The isotope-geochemical heterogeneity of basaltoids of the region is generally determined by the peculiarities of concentration of rocks with intraplate and adakite geochemical characteristics, which allows considering the asthenospheric diapirism as the main factor of petrogenesis of Pliocene-Quaternary volcanism in Kamchatka.

The paper presents new geological and isotope-geochemical data on rock composition from the head of the Kikhchik River, the outer NW part of Miocene-Pliocene volcanic belt of Central Kamchatka. The authors obtained age characteristics (40K−40Ar dates): 9.8 and 9.1 Ma for Kecheva massif and 8.3 and 7.8 Ma for Aopchi cones. New data on ages and analytical materials allow substantial updating our understanding of the rock composition from this volcanic belt as well as the beginning of volcanic activity. The authors revealed complex rocks, both completely identical to closely located volcanic manifestations (Kecheva) and abnormally enriched with Rb, Pb, Ba, Zr, Hf, Nb, U, Th and radiogenic Sr Aopchi, Kabanikha, littoral cones. The origin of these anomalous volcanites was likely caused by the partial melting of the mantle source close to the Sp- peridotite metasomatically reworked by the processes that may relate both to dehydratation of the subducting oceanic plate, and by the effect from the asthenospheric diapir.

В работе показано, что в размещении современных гидротермальных систем и вулканических
пород плиоцен-четвертичного возраста на Камчатке большая роль принадлежит разломам северо-восточного простирания, вдоль которых с юго-запада на северо-восток прослеживается последовательное "омоложение" вулканических пород, сужение областей их распространения, уменьшение диаметра купольно-кольцевых структур, выклинивание зон новейших разрывных нарушений, возрастание естественных ресурсов тепла, аккумулированного горными породами известных гидротермальных систем. Последовательное смещение к северо-востоку проявлений вулканической и гидротермальной деятельности выявлено также в пределах отдельных вулканических
центров, приуроченных к этим разломам. Показано, что удовлетворительного объяснения выявленным закономерностям в настоящее время нет. Наиболее вероятно последовательное смещение к северо-востоку магмы, поднимающейся вдоль фронта Курило-Камчатской дуги.
