The vein mineral assemblages were in equilibrium with the greenschist assemblages. The formation of veins by "open-space" filling followed by regional F1 folding ending with the fixing of slaty ...

Metabasite refers to metamorphosed basalts and other mafic igneous rocks (rich in iron and magnesium). When a mafic igneous rock is subjected to new pressure and temperature conditions during ...

These supracrustal rocks underwent greenschist metamorphism and a further event of high-temperature and low-pressure (HT/LP) (750°C and ~2 kbar) conditions (Lindenmayer et al. 1994). Rare ...

Barrovian metamorphism is distinguished by a high vertical temperature gradient that, when extrapolated, yields temperatures of 800°C to 850°C at the base of 35-kilometer-thick crust—nearly ...

One of the best ways to learn how to work with shear zones and metamorphism is to study real-world examples from different regions and settings. You can find many published papers, reports, maps ...

3. Petrography Amphibole and plagioclase are the main minerals in the greenschist and amphibolite, and the secondary mineral in some micaschist seen in the area. Amphibole was seen in greenschist with ...
