Lub xub ntiag ntawm pob zeb foliated, zoo li slate, qhia tias ua ntej lub pob zeb no metamorphosed nws tau tsim los ntawm limestone (niam txiv pob zeb ntawm marble) txheej nrog me me-grained sedimentary pob zeb, zoo li siltstone lossis shale.

Marble ua ntej metamorphism yog dab tsi?

Ua ntej metamorphism, cov calcite hauv limestone feem ntau yog nyob rau hauv daim ntawv ntawm lithified fossil khoom thiab cov khib nyiab lom. Thaum lub sij hawm metamorphism, qhov no calcite recrystallizes thiab kev ntxhib los mos ntawm pob zeb hloov. Nyob rau theem pib ntawm limestone-rau-marble transformation, cov calcite crystals nyob rau hauv lub pob zeb yog heev me me.

pob zeb dab tsi yog marble ua ntej?

Marble yog pob zeb metamorphic. Cov pob zeb metamorphic yog cov pob zeb uas tau hloov pauv hauv cov muaj pes tsawg leeg vim qhov kub thiab txias. Marble pib li limestone ua ntej yuav raug hloov pauv, hu ua metamorphism.

Tus thawj daim ntawv ntawm marble yog dab tsi?

Marble yog lub pob zeb metamorphic tsim thaum limestone raug rau qhov kub thiab txias. Marble cov ntaub ntawv nyob rau hauv xws li tej yam kev mob vim hais tias cov calcite tsim cov limestone recrystallises ua ib lub pob zeb denser muaj roughly equigranular calcite crystals.

Dab tsi yog pob zeb metamorphic ua ntej nws hloov?

Metamorphic pob zeb pib tawm ua lwm hom pob zeb, tab sis tau hloov pauv ntau yam ntawm lawv thawj igneous, sedimentary, los yog ua ntej metamorphic form Metamorphic pob zeb tsim thaum pob zeb raug rau kub kub, siab siab, kub ntxhia nplua nuj kua los yog, feem ntau, ib co ua ke ntawm tej yam.
