Reviews of Geophysics, 1983
Continued advances in thermodynamic models of mineral and fluid equilibrium and in the kinetics of mineral reactions have made metamorphic petrology a quantitative science. Thermometers and barometers for many rocks are accurate enough to locate the origin of the rocks in the crust and mantle, and the development of kinetic models promises to enable ...

Structure and metamorphic petrology of the Forth metamorphic complex
2023The Forth Metamorphics outcrop in the lower reaches of the Forth River, Northern Tasmania and comprise a banded garnetiferous schist and quartzite, interlayered with sub-ordinate orthoamphibolites of tholeiitic MORB-type affinity. Geochemical and sedimentological constraints are consistent with a passive continental depositional environment and the ...

METPET: Metamorphic petrology microcomputer programs
Journal of Metamorphic Geology, 1990METPET is a package of three interactive microcomputer (IBM PC or compatible) programs. FILEMAN is a utility program to create, edit and print ‘composition files’, i.e. files containing the records of chemical compositions of minerals or rocks, expressed in terms of primary chemical components. PROJECT recalculates selected compositions in terms of new

Petrological consequences of variations in metamorphic reaction affinity
Journal of Metamorphic Geology, 2011The extent to which kinetic barriers to nucleation and growth delay the onset of prograde metamorphic reaction, commonly known as overstepping, is related to the macroscopic driving force for reaction, termed reaction affinity. Reaction affinity is defined in the context of overstepping as the Gibbs free-energy difference between the thermodynamically ...

Metamorphic events in the eastern Arunta Inlier, Part 1. Metamorphic petrology
Precambrian Research, 1995Abstract In the Entia Dome of the eastern Arunta Inlier kyanite-facies metamorphism is recorded over a substantial area (at least 160 km 2 ) and thus contrasts with the regionally extensive belts of high-temperature-low-pressure andalusite-sillimanite facies metamorphism documented elsewhere in the Arunta Inlier. This amphibolite facies event appears

Experimental petrology related to extreme metamorphism
Tectonophysics, 1977Abstract The symposium was planned and organized by the Commission on Experimental Petrology at High Pressures and Temperatures (CEPHPT), a commission of the International Union of Geological Sciences (IUGS). A central purpose was to present before a wide geological audience papers which illustrated the application of the results of laboratory ...

Basic Concepts of Metamorphic Petrology
1965Metamorphism usually takes place in response to a rise of temperature. Progressive changes brought about in rocks by rising temperature are called progressive metamorphism. Successive rises of temperature bring about a series of reactions, which might be understood as changes of mineral assemblages approximately at equilibrium.

PETROLOGICAL FEATURES OF SHOCK METAMORPHISM IN CHONDRITES: ALFIANELLO [PDF]
Meteoritics, 1971 The Alfianello meteorite was inspected by optical microscopy, both by transmitted and reflected light, in order to look for evidence of shock metamorphism. The stone is a well‐recrystallized olivine‐hypersthene chondrite that shows unambiguous features of dynamic deformation.

Applications of thermodynamics in metamorphic petrology
1976This paper summarizes the principles of chemical thermodynamics in a form which is convenient for dealing with problems encountered in metamorphic petrology. Particular effort has been made to illustrate thermodynamic concepts by means of graphical representation.
