Metamorphism ntawm quartz-nplua nuj sandstone tsim quartzite (Fig. 8.9), ib qho nyuaj heev, nonfoliated metamorphic pob zeb muaj yuav luag tag nrho ntawm silica. 2. Metamorphism ntawm limestone thiab dolomite ua rau recrystallization ntawm calcite los ua marble (Fig.
Cov pob zeb twg yog feem ntau tsim los ntawm metamorphism ntawm cov xuab zeb?
Quartzite yog tsim los ntawm sandstone uas tau metamorphosed. Quartzite yog nyuaj dua li cov niam txiv pob zeb sandstone. Nws tsim los ntawm sandstone uas tau nkag mus rau hauv kev sib cuag nrog cov magmas tob tob.
Puas yog feem ntau tsim los ntawm metamorphism ntawm quartz sandstone?
_ feem ntau yog tsim los ntawm metamorphism ntawm sandstone. Lub sij hawm twg piav txog thaj tsam ntawm kev sib cuag metamorphism nyob ib puag ncig lub cev magma? Foliated cov pob zeb metamorphic yog tsim los ntawm cov khoom noj muaj txiaj ntsig zoo xws li quartz thiab calcite.
4 hom kev hloov pauv loj yog dab tsi?
Top 4 Hom Metamorphism| Pob zeb | Geography
- Type 1. Contact Metamorphism:
- Type 2. Regional Metamorphism:
- Type 3. Hydro-Metamorphism:
- Type4. Hydro-Thermo-Metamorphism:
Lub pob zeb twg yog tsim los ntawm lub regional metamorphism?
Feem ntau foliated metamorphic pob zeb- slate, phyllite, schist, thiab gneiss-yog tsim thaum lub sij hawm hauv cheeb tsam metamorphism. Raws li cov pob zeb ua kom sov ntawm qhov tob hauv lub ntiaj teb thaum lub sij hawm lub cheeb tsam metamorphism lawv ua ductile, uas txhais tau hais tias lawv kuj mos txawm tias lawv tseem khov.
