Experimental Metamorphic Petrology

Since Bowen and Tuttle's pioneering study of the system MgO-SiO2-H2O in 1949, advances in experimental metamorphic petrology have occurred steadily rather than in “leaps and bounds”. The number and quality of papers published during the past quadrennium, 1975–1978, attests to the health of the science. Although the purpose of this report is to focus international attention on the U.S. effort in experimental metamorphic petrology, some papers published by foreign experimentalists have been included, especially where their contributions complement those made in the U.S. To keep the review current, abstracts of papers read at national meetings of the Geological Society of America and the American Geophysical Union in 1978 are included.
