Applications of Raman Spectroscopy in Metamorphic Petrology and Tectonics

Elements, 2020
Raman spectroscopy is widely applied in metamorphic petrology and offers many opportunities for geological and tectonic research. Minimal sample preparation preserves sample integrity and microtextural information, while use with confocal microscopes allows spatial resolution down to the micrometer level.

Principles of Igneous and Metamorphic Petrology

2009
Building upon the award-winning second edition, this comprehensive textbook provides a fundamental understanding of the formative processes of igneous and metamorphic rocks. Encouraging a deeper comprehension of the subject by explaining the petrologic principles, and assuming knowledge of only introductory college-level courses in physics, chemistry ...

The three partners of metamorphic petrology

American Mineralogist, 2011
Study of the evolution of the Earth’s crust advanced greatly in the last half-century through the dynamic collaboration of three equally contributing partners: field observations, together with microanalysis of mineral assemblages, experimental petrology, and stability calculations based on systematically measured and compiled thermodynamic properties ...

Metamorphic petrology of the Sarmiento ophiolite complex, Chile

Geology, 1978
The Sarmiento Complex of southern Chile is a Mesozoic ophiolite that underwent hydrothermal “ocean-floor metamorphism” prior to its uplift and exposure in the Andean Cordillera. The overprint of this metamorphism exhibits a steep vertical metamorphic gradient although the extent of metamorphic replacement decreases markedly within the gabbro unit of ...

Experimental petrology related to extreme metamorphism

Tectonophysics, 1977
Abstract 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

1965
Metamorphism 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

1976
This 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.

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).

Petrologic comparison of the franciscan and sanbagawa metamorphic terranes

Tectonophysics, 1967
Abstract 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.
