A pelite (from Ancient Greek πηλός (pēlós) 'clay, earth') or metapelite is a metamorphosed fine-grained sedimentary rock, i.e. mudstone or siltstone.
Pelito (do grego πηλός, translit. pelós, 'lodo', 'argila') é uma rocha sedimentar detrítica clástica - isto é, formada com os fragmentos ou detritos oriundos da destruição de outras rochas - cujos componentes principais são minerais da granularidade das argilas e siltes e que se originam pela litificação de lamas.
8 de mai. de 2018 · pelite (adj. pelitic) An aluminium-rich, metamorphic rock formed by the metamorphism of clay-rich sedimentary rocks, e.g. shales and mudstones.
The protolith (or parent rock) for phyllite is shale or pelite; or slate, which in turn came from a shale protolith. Its constituent platy minerals are larger than those in slate but are not visible with the naked eye.
2 de nov. de 2022 · Pelites (shales and mudstones) are arguably the most important rock type for interpreting metamorphism. Their significance derives from their widespread occurrence and the range of mineral assemblages they develop at different conditions of pressure and temperature.
Due to thermal and mechanical stability, non-toxicity, and high resistance against microbial attacks and organic solvents, perlite is widely used in biotechnological applications. Perlite was found to be an excellent support for immobilization of biocatalysts such as enzymes for bioremediation and sensing applications.
The term pelite refers in a general sense to sedimentary protoliths that are fine-grained and dominated by clay. As the proportion of silt increases in the source rock, the metamorphosed equivalent is then commonly referred to as a semi-pelite, although there is no formal definition of when this lithological transition occurs (Bucher and Frey ...
