Metamorphism of Marls [PDF]

, 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.

Metamorphism of Pelites [PDF]

, 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 ...

Himalayan Metamorphism and Its Tectonic Implications

, 2014
The Himalayan range exposes a spectacular assemblage of metamorphic rocks from the mid- and deep crust that have fostered numerous models of how the crust responds to continental collisions.

Some Precambrian banded iron-formations (BIFs) from around the world: Their age, geologic setting, mineralogy, metamorphism, geochemistry, and origins

, 2005
Banded iron-formations (BIFs) occur in the Precambrian geologic record over a wide time span. Beginning at 3.8 Ga (Isua, West Greenland), they are part of Archean cratons and range in age from about 3.5 until 2.5 Ga.

The Metamorphism of the South-West Highlands.

Geological Magazine, 1923
Last year, I published a theory of the structure of the South-West Highlands in which was included a short statement regarding the metamorphism of the district (1922, p. 92). It seems that movement and metamorphism in this particular region have been too

Low‐pressure–high‐temperature metamorphism during extension in a Jurassic magmatic arc, Central Pontides, Turkey

, 2014
Magmatic arcs are zones of high heat flow; however, examples of metamorphic belts formed under magmatic arcs are rare. In the Pontides in northern Turkey, along the southern active margin of Eurasia, high temperature–low pressure metamorphic rocks and ...

Dating subduction‐zone metamorphism with combined garnet and lawsonite Lu–Hf geochronology

, 2014
Studies of ancient and active subduction zones are critically important to understanding processes of interplate coupling, crust‐mantle recycling and arc magmatism.

On metamorphism in meteorites

, 1921
Introductory Statement For some years there has been a growing feeling among those who have given the subject consideration, that the peculiar structures found in many meteoric stones are due not to hasty crystallization from a molten magma, as has been ...
