Joseph Paxson Iddings was een Amerikaanse geoloog en hoogleraar petrologie wiens onderzoek het vakgebied van de petrologie en het begrip van stollingsgesteenten diepgaand vormde. Zijn werk beïnvloedde fundamenteel ons begrip van hun vorming en kenmerken. Zijn wetenschappelijke bijdragen werden geëerd met de naamgeving van het mineraal iddingsiet en een trilobietfossiel ter zijner nagedachtenis.
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.
