Kev sib cuag metamorphism tshwm sim nyob qhov twg uas intrusion ntawm plutons tshwm sim . Hauv cov ntsiab lus ntawm phaj tectonics txoj kev xav, plutons nkag mus rau hauv lub crust ntawm convergent phaj ciam teb, nyob rau hauv rifts, thiab thaum lub roob lub tsev uas yuav siv qhov chaw uas continents sib tsoo.

Hauv qhov no, nyob rau hauv qhov chaw tectonic yuav hu rau metamorphism tshwm sim?

Hu rau metamorphism yog li no feem ntau yog thermal phenomenon. Nws yuav tshwm sim hauv ntau haiv neeg kev teeb tsa tectonic xws li nyob rau hauv orogenic lossis anorogenic ib puag ncig, hauv phaj interiors los yog nrog phaj cov npoo.

Tom qab ntawd, lo lus nug yog, qhov twg metamorphism tshwm sim Dab tsi yog cov xwm txheej hauv qab uas metamorphism tshwm sim? Metamorphism , yog li ntawd tshwm sim ntawm qhov kub thiab txias siab tshaj 200oC thiab 300 MPa. Pob zeb tuaj yeem raug rau qhov kub thiab txias siab dua li lawv tau faus tob dua hauv lub ntiaj teb. Xws li faus feem ntau siv qhov chaw raws li qhov tshwm sim ntawm Cov txheej txheem tectonic xws li kev sib tsoo sab av loj lossis kev sib tsoo.

Yog li ntawd, metamorphism cuam tshuam li cas rau phaj tectonics?

Metamorphic pob zeb tshwm sim los ntawm lub zog ua haujlwm thaum lub sijhawm phaj tectonic txheej txheem. Cov tectonic quab yuam deform thiab tawg lub pob zeb, tsim qhib, tawg, faults, breccias, thiab ib cheeb tsam ntawm tsis muaj zog raws li magmas. ua tau sawv.

Dab tsi ntawm phaj ciam teb yog metamorphism feem ntau?

Hu rau metamorphism yog feem ntau ob ob convergent thiab divergent phaj ciam teb , nyob rau hauv cov cheeb tsam uas molten pob zeb yog tsim. Hauv cheeb tsam metamorphism feem ntau tshwm sim ntawm convergent phaj ciam teb . Txhua tus ntawm no hom ntawm metamorphism ua raug metamorphic pob zeb, tab sis lawv yuav tshwm sim nyob rau hauv txawv sequences.
