Experimental metamorphic petrology

The past quadrennium, 1971–1974 inclusive, has seen a great variety of published work in experimental metamorphic petrology. Numerous phase equilibrium studies as well as many determinations of physical properties of minerals have been produced. Whereas the last report contained 270 references, this report contains over 475, illustrative not only of the activity of the science but also of the wider scope of articles necessary to describe the interactions within modern petrology. In this review, metamorphism has generally been taken to cover the temperature range from 10O°C to the solidus in the appropriate bulk compositions and mineral groups. A few articles containing liquidus data have been referenced when significant subsolidus data were also included. Most of the references are in the English language and from North American—or European‐based publications. Unavoidably, many pertinent foreign experimental data are excluded. Nevertheless, trends in research are thought to be reasonably well displayed. An attempt was made to keep the review as current and useful as possible by including abstracts from the principal meetings, in 1974, of the Geological Society of America and the American Geophysical Union.
