The mechanisms of magma movement, chemical differentiation and physical development, are derived from the geochemistry of igneous rocks, and from studying exposures of deep magmatic systems that have since solidified and been uplifted and exposed at the Earth's surface. The Ferrar Magmatic System of the McMurdo Dry Valleys in Antarctica provides an unparalleled example of a complete magmatic-volcanic system exposed in unprecedented detail. This book provides a unique and usual three-dimensional detailed examination of this system, providing insight into many magmatic processes normally unobservable, in particular how basaltic magma moves upwards through the crust, how it entrains, carries and deposits loads of crystals from great depths, and how this all contributes to Earth's evolution. Providing an explanation of how magmatic systems operate and how igneous rocks form, this is an invaluable resource ideal for researchers and graduate students in magma physics, igneous petrology, volcanology, and geochemistry.
