The Evolution of the Igneous Rocks, by N. L. Bowen, appeared in 1928 and had a profound influence on later generations of petrologists. Drawing on his series of lectures at Princeton University in the spring of 1927, Dr. Bowen identified, outlined, and applied the principles of physical chemistry relevant to petrological processes. Whereas the major petrochemical questions he discussed are still relevant today, the answers appear to change with time. The purpose of the present volume is to provide an updated view of those questions, in the light of almost fifty years of accumulated...

"Minerals of Georgia" presents an illustrated, alphabetized record of every mineral (or mineral group) identified in the state. Under each entry is a county-by-county listing of every occurrence known, including both widespread species and obscure ones. In addition to economically important mineral deposits, this volume covers various mineral localities within the state that are well known among professional mineralogists, mineral collectors, and rockhounds as the source of outstanding study, display, and lapidary material.

Illustrated with over 150 color photographs this guide provides...

While the chemical aspects of igneous petrology have dominated research for many years, the physical processes associated with the generation, transport, and crystallization of magma have been somewhat neglected. Here a group of distinguished scientists, whose current research embraces both chemical and physical aspects of the field, illustrates these new directions in igneous petrology.

Originally published in 1980.

Rock-Medicine differs from other ideological schools of thought regarding crystal and stone influences. Over time, the science behind Rock-Medicine has gained legitimacy by identifying that minerals are precision chemical instruments capable of balancing one's mind, body and spirit to a state of well being through a system devoid of mysticism, subjectivity or illusory conventions.
The laws of chemistry and the laws of quantum/standard physics unite the function of Rock-Medicine. At the foundation of all tangible existence is math and chemistry. All life on our planet, and the planet...

This is a comprehensive study of forest soils for foresters, wildlife and park managers, ecologists, and others interested in forest soils. It provides a valuable text for introductory and more advanced courses.

The first ten chapters deal with basic soil information: texture, structure, and porosity; colour, temperature, and aeration; water; organic content; biological organisms and processes; chemistry; fertility; classification; and surveys. The last six chapters consider the components of the forest soil systems as related processes, discussing roots, fire, and water and...
