Quantitative determination of metamorphic reaction history: mass balance relations between groundmass and mineral inclusion assemblages in metamorphic rocks
Article Abstract:
A mathematical method called the singular value decomposition technique may be used to determine the history and pressure-temperature paths of metamorphic reactions. Researchers applied this technique to inclusions and groundmass assemblages from a kyanite-mica schist from British Columbia and a sillmanite-cordierite gneiss from Washington State. The mass balance results obtained from this algebraic technique agree with those obtained from petrographic studies of the probable pressure-temperature path of formation of each of these terranes.

The timing and direction of metamorphic fluid flow in Vermont, by A.D.L. Skelton: discussion
Article Abstract:
The conclusion by Alasdair Skelton that the major metamorphic fluid flow at the northern end of the Strafford dome in east-central Vermont was localized in the hinge zones of D2 is erroneous. The error is due to his calculation of the distribution of coarse garnet schists. The fluid-rock reactions to generate the aluminous bulk composition that led to the growth of garnet was prior to the formation of the Strafford dome.

Geochemistry and age of ultrahigh pressure metamorphic rocks, from the Kokchetav massif (Northern Kazakhstan)
Article Abstract:
An analysis of metamorphic rocks from the Zerenda series is presented, focusing on various indicators of ultrahigh pressure metamorphism. The authors discuss the microdiamond inclusions of metamorphic rocks, and evaluate the relationship between the earth's crust formation and high pressure metamorphism.
