A pelite (from Ancient Greek πηλός (pēlós) 'clay, earth') [3] or metapelite is a metamorphosed fine-grained sedimentary rock, i.e. mudstone or siltstone.

Pelitic rocks metamorphosed under sanidinite-facies conditions are quite rare and are most commonly found as xenoliths within plutons. These pelitic rocks, characterized by the absence …

2022年8月28日 · Metapelites are rich in Al, Si, and K and may contain substantial amounts of Fe and Mg, so minerals containing these elements dominate metapelitic rocks. The table below …

Pelitic rocks are derived from mudstone (shale) protoliths and are rich in potassium (K), aluminum (Al), silicon (Si), iron (Fe), magnesium (Mg), and water (H 2 O), with lesser amounts of …

2020年1月1日 · Regional metamorphism of pelitic rocks during orogenesis produces the well-known Barrovian prograde succession, with index minerals chlorite, biotite, garnet, staurolite, …

Pelitic Rocks Read Chapter 3 of An Introduction to Metamorphic Petrology by Bruce Yardley or Chapter 28 of Igneous and Metamorphic Petrology by John Winter The protoliths for pelitic …

Pelite refers to clay-rich sedimentary rocks that form in low-energy environments and undergo a great diversity of mineral assemblages and textures when metamorphosed under changing …

2022年11月2日 · Pelites (shales and mudstones) are arguably the most important rock type for interpreting metamorphism. Their significance derives from their widespread occurrence and …

Typical metapelites include well-known metamorphic rocks such as, for example: chlorite-kyanite-schists, staurolite-garnet micaschists, chlori-toid-garnet micaschists, kyanite-staurolite schists, …

Semi-pelitic rocks with a high proportion of silt (siltstones) and less clay transform to metamorphic equivalents with less interesting and diagnostic mineral assemblages. K. Bucher and R. …
