Volcanic pipes
Abstract
The book is concerned with the geology and the composition of kimberlite pipes, ancient vent funnels, active volcanos erupting alkali-basaltic and carbonatite products, and diatremes formed by trappean and trachyte rocks. The discussion is illustrated by the data available for the best-studied diatremes in central Siberia, Onega Peninsula, northern Tanzania, and other regions. In particular, a comparative analysis is made of the geological conditions, tectonically controlled localization, shape, size, and other characteristics of diatremes filled with various minerals. Results of studies of the mechanisms and conditions of the formation of diatremes are presented.
