The oldest geological society in the world – The Geological Society of London – has recently published a book "Lamprophyres, Lamproites and Related Rocks: Tracers to Supercontinent Cycles and Metallogenesis". The book deals with igneous rocks which originated at great depths in the Earth's mantle and provide unique potential for the study of geological processes involved in the formation and break-up of geological supercontinents such as Colombia, Rodinia and Gondwana–Pangea. The main editor of the book is Assoc. Prof. Lukáš Krmíček, Ph.D.
