Excerpt from The Fundamental Principles of Petrology NO one who is interested in unraveling the geology Of a region will find fault with a field geologist for having the most complete knowledge possible of things paleontologic, but such knowledge does not justify him in neglecting the assistance offered by petrology; knowledge especially indispensable to the working geologist. Whoever would comprehend all the phases of geology must give petrology the same weight as paleontology, and draw upon each equally for his results.

Petrology is the branch of geology that deals with the origin, structure, and composition of rocks. This book has been compiled for professionals as well as for advanced graduate courses in petrology. It consists of research-focused information about the current developments and applications of modern petrologic and geochemical methods for comprehending metamorphic, igneous and even sedimentary rocks. Research analyses compiled in this book provide an overview on the applications of latest petrologic methodologies to rocks of diverse origins. They represent a broad variety of settings (from Africa to Central Asia, and from South America to the Far East) as well as ages ranging from late Precambrian to late Cenozoic, and also Mesozoic/Cenozoic volcanism.
