Hydrothermal metamorphism yog hom metamorphism . Kub, tshuaj lom neeg ua haujlwm, dej bearing minerals tuaj rau hauv kev sib cuag nrog cov pob zeb uas nyob ib sab preexisting ua rau qhov tshwm sim ntawm hydrothermal metamorphism . Lub pob zeb no hu ua lub teb chaws pob zeb. Nws feem ntau tshwm sim ntawm qhov tsis tshua muaj siab thiab sib piv qis qis.

Ua li no, 3 yam tseem ceeb ntawm metamorphism yog dab tsi?

Muaj peb txoj kev uas metamorphic pob zeb tuaj yeem tsim. Cov 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.

Tsis tas li ntawd, tus neeg sawv cev ntawm hydrothermal metamorphism yog dab tsi? Hydrothermal metamorphism yog qhov tshwm sim ntawm kev sib cuam tshuam ntawm pob zeb nrog cov kua dej kub ntawm qhov sib txawv. Qhov sib txawv ntawm cov pob zeb uas twb muaj lawm thiab cov kua dej invading ua rau muaj teeb meem metamorphic thiab metasomatic cov tshuaj tiv thaiv.

Tom qab ntawd, lo lus nug yog, qhov twg hydrothermal metamorphism pom?

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.

Dab tsi yog qhov dej rau hydrothermal metamorphism?

Cov kua dej kub, volatile lub luag hauj lwm rau hydrothermal metamorphism tuaj yeem muab tau los ntawm ntau yam qhov chaw . Cov kua dej zoo li no yuav muaj cov volatiles khiav ncaj qha los ntawm cov magma intrusive; Lawv kuj tseem yuav tsim los ntawm cov dej hauv av meteoric rhuab los ntawm qhov tsis pom kev nkag los yog los ntawm geothermal gradient.
