Petrogenesis and Experimental Petrology of Granitic Rocks

Granite petrology has achieved significant progress since Tuttle and Bowen (1958) wrote the monograph on the Origin of granite in the light of experimental studies in the system NaAISi308-KAISi308-SiOrH20. Since then, the compo- nents CaAI Si 0, FeO, MgO, and excess alumina have 2 2 s been added to the pure system Ab-Or-Qz-H 0 in order to 2 include plagioclase and common mafic minerals in the inves- tigations. In addition to synthetic systems, natural rocks have been used as starting materials, and other fluid compo- or substituted for water. nents have been added to There are many new data concerning properties of melts and magmas, dehydration melting of synthetic and natural rocks, and phase relationships at H 0-undersaturated con- 2 ditions. We found it useful and necessary to summarize the available information in this volume, and an effort has been made to present up-to-date data on various aspects of gran- ite petrology. Most parts of the manuscript were reviewed by John Clemens, Peter Nabelek, and Alan White. Their friendly help and suggestions improved it considerably. Some chap- ters of this volume benefited from critical review by William Brown, Bruno Scaillet, and Robert Linnen. Peter Wyllie pro- vided us with reprints and many critical and useful sugges- tions. Jagmohan Singh improved the English considerably.
