Lub luag haujlwm dab tsi ua cov kua dej tshuaj lom neeg ua si hauv metamorphism? Cov kua dej tshuaj lom neeg tuaj yeem nqa cov atom tshiab rau hauv pob zeb lossis nqa cov atom tawm ntawm pob zeb, yog li hloov cov pob zeb muaj pes tsawg leeg. Piav txog gneiss, schist, phyllite, thiab slate raws li kev ntxhib los mos thiab grain loj.
Yuav ua li cas yog qhov tseem ceeb ntawm cov kua dej tshuaj lom neeg thaum lub sijhawm metamorphism?
Thaum lub sijhawm metamorphism, qhov cuam tshuam loj ntawm cov kua dej tshuaj lom neeg yog dab tsi? Lawv pab hauv kev txav ntawm cov khoom sib xyaw silicate thiab pab txhawb kev loj hlob ntawm cov pob zeb hauv av.
Yam hloov pauv li cas thaum lub sijhawm metamorphism?
Metamorphism yog qhov hloov pauv ntawm cov ntxhia los yog geological kev ntxhib los mos (kev sib txawv ntawm cov ntxhia) hauv cov pob zeb uas twb muaj lawm (protoliths), tsis muaj cov protolith yaj rau hauv cov kua magma (kev hloov pauv hauv lub xeev). Qhov kev hloov pauv tshwm sim feem ntau vim tshav kub, siab, thiab kev qhia txog cov kua dej tshuaj lom neeg.
Yuav ua li cas thaum metamorphism?
Thaum lub sijhawm metamorphism, protolith chemistry hloov me ntsis los ntawm qhov kub thiab txias (kub), ib hom kev siab hu ua confining siab, thiab / lossis cov kua dej tshuaj lom neeg. Pob zeb kev ntxhib los mos yog hloov los ntawm tshav kub, confining siab, thiab ib hom ntawm lub siab hu ua directed stress.
Dab tsi yog cov kua dej uas muaj tshuaj lom neeg tshaj plaws?
Cov kua dej uas muaj tshuaj lom neeg feem ntau koom nrog hauv cov txheej txheem metamorphic yog dej kub uas muaj ions hauv cov tshuaj.
