This book presents essential data on the geology of the Puchezh-Katunki crater – an early Jurassic crater located on the East European Platform, with an impact structure that is ca. 80 km in diameter. Offering a comprehensive guide, it reviews the studies carried out during the last several decades on this prominent but not well-known impact structure. It offers the international community state-of-the-art information on the crater with regard to e.g. structural mapping, drilling (including the Vorotilovo well, which is 5374 m deep), geophysical research, and the petrological analysis of impactites and various breccias. In addition, the book includes new results from the mineralization and crystallizations beneath this large impact crater, and suggests new models for crater formations.

This book highlights the most prominent research on the Popigai meteorite crater (Siberia, Russia), the 6th largest known impact structure in the world. Not only does the crater have a diameter of roughly 100 km, it is also an estimated 35.7 million years old.
This monograph is an updated, extended and revised edition of the Russian-language book “Diamond-bearing Impactites of Popigai Astrobleme” and presents the most comprehensive research on the Popigai impact structure. The Popigai crater is unique in that the total amount of impact diamonds it contains exceeds all the other diamond-bearing provinces of the world.
The work presented here is based on the geological mapping, core logging, geophysical survey and petrological studies of the crater, and was written by the team of geologists who first described the Popigai impact structure and its diamonds, and took part in the exploration of their deposits from 1970 to 1985.
