Book Description
Based on hundreds of thin sections from granite in China, this book introduces metasomatic textures and their formation mechanism in granite. It also proposes that metasomatic textures can basically be classified into two patterns: hetero-oriented replacement and co-oriented replacement, according to the consistency of orientations of replacive and replaced minerals. The hetero-oriented albitization of K-feldspar is quite distinct from the co-oriented albitization of K-feldspar. They occur separately without transition, although both are generally referred to as albitization of K-feldspar.This unique granite atlas uses a series of color microphotos taken with a quartz plate under crossed polars to clearly illustrate metasomatic mechanisms and superimposed metasomatic processes. The origins of clear albite rim, intergranular swapped albite, K-feldspathization, quartzification, muscovitization, beryllization, myrmekite, small platy albite, perthitic albite, K-feldspar megacryst etc. are comprehensively discussed and explained. The book will appeal to teachers, researchers and students involved in igneous and metamorphic petrology.

Book Description
We are increasingly faced with environmental problems and required to make important decisions. In many cases an understanding of one or more geologic processes is essential to finding the appropriate solution. Earth and Environmental Sciences are by their very nature a dynamic field in which new issues continue to arise and old ones often evolve. The principal aim of this book is to present the reader with a broad overview of Earth and Environmental Sciences. Hopefully, this recent research will provide the reader with a useful foundation for discussing and evaluating specific environmental issues, as well as for developing ideas for problem solving. The book has been divided into nine sections; Geology, Geochemistry, Seismology, Hydrology, Hydrogeology, Mineralogy, Soil, Remote Sensing and Environmental Sciences.

Book Description
Microtectonics is the interpretation of small-scale deformation structures in rocks. They are studied by optical microscope and contain abundant information on the history and type of deformation and metamorphism in a rock and are therefore used by most geologists to obtain data for large-scale geological interpretations. This advanced textbook contains a large number of photographs and explanatory drawings, special chapters on related techniques, a chapter on microgauges and a simple, non-mathematical treatment of continuum mechanics with practical examples. Special terms are explained in boxes. This textbook is suited for independent use during optical studies on microstructures as a reference manual and as a manual for short courses.

Book Description
Remarks by JVS. Volumes 1 and 2 of Feldspar Minerals were published in 1974, but Volume 3 was not completed because I was forced to devote 3 years to the resolution of unforeseen problems in the construction of an ion probe. By 1977, the incomplete draft for Volume 3 had become obsolete because of the enormous advances in knowledge of feldspars, particularly those in lunar rocks and meteorites, and in both deep-seated and ancient terrestrial rocks. Furthermore, it soon became obvious that a completely new version of Feldspar Minerals was needed because of the important new results on the physical and chemical properties. I had kept up with the interesting but tedious chore of weekly reading of the incoming literature and maintenance of the files. By 1980, the intense day-to day pressure had gone from my research programs on lunar rocks and on the development of the ion microprobe as a quantitative geochemical instrument, and I began preparation of a second edition of Feldspar Minerals.
