A new perspective on metamorphism and metamorphic belts☆
Gondwana Research, 2010Abstract The discovery of ultrahigh-pressure rocks from collision-type orogenic belts has revolutionized the classic interpretation of (1) progressive and retrogressive metamorphism recorded on surface exposures of regional metamorphic belts, (2) geochronology of the various stages of metamorphism, (3) origin of metamorphic textures, (4) P – T – t ...

Metamorphism and metamorphic mechanisms
1977We made a brief reference to metamorphism of meteorites in Chapter 6. Metamorphic rocks constitute an important part of the Earth’s crust. During the last two decades very significant progress has been made in the experimental techniques for the study of rock systems.

, 1994 Marls are carbonate-bearing pelitic sediments covering a wide range of composition between “impure” carbonate rocks and “true” pelites. In the Anglo-American literature, this group of sedimentary rocks is better known as argillaceous carbonate rocks, calcareous sediments, calcic pelitic rocks, or calcareous pelites.

, 1974 Slates, phyllites, and mica schists are derived from clay. They belong to the large group of metamorphic rocks known as metapelites. In addition to quartz, the following minerals are common constituents of these rocks: Pyrophyllite, andalusite, kyanite, sillimanite Staurolite Chloritoid, cordierite Chlorite, almandine-rich garnet The K ...

Temperature and pressure are the physical factors that control the process of metamorphism. Metamorphism, in general, refers to the reactions between neighboring minerals of a rock in response to conditions of temperature and pressure prevailing at depth.

Marls constitute a group of sedimentary rocks with a very large range of composition. The clay constituents, predominantly dioctahedral micas (illite, phengite, muscovite), chlorite, and quartz, are mixed with calcite and/or dolomite in varying proportions.

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 ...

Definition and Types of Metamorphism
1965Igneous rocks formed at relatively high temperatures of approximately 650° to 1200°C and sediments deposited at the earth’s surface represent extreme ends of the temperature range realized in the processes of rock formation. In the course of later geological events such rocks may become part of a region in the earth’s crust where intermediate ...
