Joseph Paxson Iddings byl americký geolog a profesor petrologie, jehož výzkum zásadně ovlivnil obor petrologie a porozumění vyvřelým horninám. Jeho práce formovala naše chápání jejich vzniku a vlastností. Jeho vědecký přínos byl oceněn pojmenováním minerálu iddingsit a zkameněliny trilobita na jeho počest.
First published in 1904, this book is a seminal work in the field of petrology. In it, the authors describe a new system for classifying igneous rocks based on their chemical and mineral makeup, a system that is still widely used today. With its rigorous analysis and detailed descriptions, this book is a must-read for anyone working in the field of geology.
In this groundbreaking work, Joseph Paxson Iddings offers a thorough examination of the science of volcanism. Drawing upon his extensive fieldwork in Hawaii and other volcanic regions, Iddings presents a detailed analysis of the geological processes that give rise to volcanic activity. With its precise scientific language and detailed illustrations, The Problem of Volcanism is a must-read for anyone interested in the complex workings of our planet.
