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.

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.

The Carnmenellis Granite: Its Petrology, Metamorphism and Tectonics [PDF]
Quarterly Journal of the Geological Society of London, 1934 I. Introduction The Carnmenellis granite and its metamorphic aureole were mapped, in 1839, by de la Beche. The area has since been re-surveyed by the Geological Survey and the results recorded in the one-inch maps, nos. 352 and 359 (New Series) and in the Survey Memoir on the Falmouth and Camborne district (Hill & MacAlister, 1906).

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.

Petrologic comparison of the franciscan and sanbagawa metamorphic terranes
Tectonophysics, 1967Abstract Mafic schists in California carry the typical blueschist facies assemblage of glaucophane—crossite + lawsonite 4 sphene + chlorite ± aragonite or calcite ± pumpellyite. Albite, epidote and actinolite are not common in “in situ” metabasalts.

A Contribution to the Petrology of the Metamorphic Rocks of East Greenland
Quarterly Journal of the Geological Society of London, 1932I. I introduction T he main object of the present paper is a petrological description and a consideration of the genesis of the metamorphic rocks collected by the Cambridge 1926 and 1929 East Greenland Expeditions.

Petrological evolution of the metamorphic sole of Oman
2013Obduction corresponds to one of plate tectonics oddities, whereby fragments of dense, oceanic lithosphere (ophiolites) are presumably 'thrust' on top of light continental ones. Though reported from most convergent belts, the emplacement of ophiolites is still poorly understood. The thin HT metamorphic soles (i.e.

Notes on the Petrology and Mineralogy of the Barrovian Metamorphic Zones
Geological Magazine, 1957AbstractThe antipathetic relation between chloritoid and biotite in the lower metamorphic grades of the Barrovian zones and the genesis of the index minerals in the higher metamorphic grades are briefly discussed. The observed mineral assemblages of 13 new analyses of peltic schists are compared with the assemblage required by the mineralogical phase ...
