Petrology and geochemistry of Shetland granites. [PDF]

This study is concerned with the distribution, age, chemistry and geotectonic setting of the 21 granites in Shetland. The granites range in size from a few metres to 8 Km across and in age from Pre-Moine to early Carboniferous.

Understanding granites: Integrating new and classical techniques

, 2000
Granite magmatism represents a major contribution to crustal growth and recycling and, consequently, is one of the most important mechanisms to have contributed to the geochemical differentiation of the Earth's crust since the Archaean times.

Physicochemical conditions of the formation of the Larino granite-gneiss dome (South Ural)

Georesursy
The Larino granite-gneiss dome is located on the border of the Aramil-Sukhtelya and Magnitogorsk megazones and is a two-headed anticlinal structure, the nuclear parts of which are composed of granitoids of the Pervomai and Larino massifs, and their ...

Intraplate crustal remelting as the genesis of Jurassic high-K granites in the coastal region of the Guangdong Province, SE China

, 2013
The origin and tectonic significance of high-K granites (>3 wt% K2O at 70 wt% SiO2), calc-alkaline I-type granites in particular, remain controversial.

Lachlan Fold Belt granites revisited: high- and low-temperature granites and their implications

, 2015
Many of the granites in southeastern Australia possess compositional, petrographic, zircon age inheritance and other features that cannot be accounted for satisfactorily by the classical models of petrogenesis.

The felsic granites of far north Queensland

, 1991
North Queensland has been the site of widespread and voluminous recurrent felsic magmatism, with granite emplacement occurring in the Middle Proterozoic, in the Silurian and Devonian, and in the Carboniferous and Permian.

Are granites and granulites consanguineous?

, 2015
© 2015 Geological Society of America. An important question in petrology is whether the production of granite magma in orogens is a closed-system process with respect to mass input from the mantle.
