Permeability of the Continental Crust: Dynamic Variations Inferred from Seismicity and Metamorphism

, 2010
The variation of permeability with depth can be probed indirectly by various means, including hydrologic models that use geothermal data as constraints and the progress of metamorphic reactions driven by fluid flow.

Structure and metamorphic petrology of the Forth metamorphic complex

2023
The 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

1965
Igneous 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 ...

Classification Principles: Metamorphic Facies versus Metamorphic Grade

1974
It was a milestone in the understanding of metamorphic petrology when Eskola (1915) published his concept of metamorphic facies with the intention of replacing the earlier Becke (1913) and Grubenmann (1910) concepts of metamorphic depth zones. Nevertheless this concept of depth zones was elaborated and slightly modified by Grubenmann and Niggli (1924 ...
