Hydrothermal Metamorphism (Fig. 8.3): feem ntau tshwm sim nyob rau hauv nruab nrab-dej hiav txwv ridge kis chaw uas rhuab seawater percolates los ntawm kub, tawg basalt.

Yog li, qhov twg hydrothermal metamorphism tshwm sim?

Ntau hydrothermal metamorphism tshwm sim ntawm thaj tsam ntawm daim phiaj dej hiav txwv. Cov phaj uas txav sib nrug tso cai rau dej hiav txwv percolate los ntawm dej hiav txwv crust. Raws li cov seawater migrate, nws heats thiab reacts nrog tus tswv pob zeb.

Tsis tas li ntawd, yuav ua li cas thaum metamorphism? Metamorphism yog qhov kev hloov ntawm cov ntxhia los yog geological kev ntxhib los mos (kev sib txawv ntawm cov ntxhia) nyob rau hauv cov pob zeb uas twb muaj lawm (protoliths), tsis muaj cov protolith yaj mus rau hauv cov kua magma (kev hloov pauv hauv lub xeev). Metamorphism ua nrog nce siab thiab kub tej yam kev mob yog hu ua prograde metamorphism.

Piv txwv li, qhov twg metamorphism tshwm sim?

Feem ntau metamorphism siv qhov chaw nyob rau hauv ib cheeb tsam uas pib ob peb kilometers hauv qab ntawm qhov chaw thiab txuas mus rau sab sauv mantle. Qhov twg feem ntau metamorphism tshwm sim ? Foliated pob zeb yog banded metamorphic pob zeb uas tsim thaum cov zaub mov realign raws li qhov tshwm sim ntawm kev siab los ntawm kev tawm tsam.

Dab tsi yog hom metamorphism?

Muaj peb txoj hauv kev uas cov pob zeb metamorphic tuaj yeem tsim. Peb hom metamorphism yog kev sib cuag, Regional, thiab Dynamic metamorphism . Hu rau Metamorphism tshwm sim thaum magma los ntawm kev sib cuag nrog lub cev pob zeb uas twb muaj lawm.
