uas tau hloov pauv raws li qhov tshwm sim ntawm cov cua sov tso tawm los ntawm magma hu ua hu aureole.
tus hu aureole yog dab tsi?
Tus hu aureole yog lub plhaub ntawm metamorphosed lossis metasomatized pob zeb enveloping lub cev tsis muaj zog(Fig.1). Qhov zoo tshaj plaws hu rau aureole cov ntaub ntawv hauv zos nyob ib ncig ntawm ib qho magma tom qab nws muab tso rau. Metamorphism hla thaj chaw loj dua tuaj yeem tshwm sim los ntawm kev sib koom ua ke ntawm ob peb qhov kev sib cuag auoreoles.
Aureole nyob qhov twg?
tshwm sim hauv cov pob zeb metamorphic
Kev sib cuag aureoles-cov cheeb tsam ib puag ncig ntawm pob zeb uas hloov pauv lossis metamorphosed-vary nyob rau hauv tuab ntawm ntau centimeters (nyob ib ncig ntawm lub cev xws li dikes thiab nyias sills) mus rau ob peb kilometers (nyob ib ncig ntawm loj granite intrusions).
Kev sib cuag metamorphism txhais li cas?
Hu rau metamorphism. Qhov no yog metamorphism ua los ntawm kev nkag mus ntawm magmaKub thiab kua dej los ntawm crystallizing magma ua rau cov tshuaj thiab mineralogical hloov nyob rau hauv cov pob zeb raug intruded. … Tsis zoo li cov pob zeb metamorphic hauv cheeb tsam, cov pob zeb faus metamorphic khaws cov khoom qub qub thiab cov ntxhia.
Qhov piv txwv ntawm kev sib cuag metamorphism yog dab tsi?
Ib qho piv txwv ntawm kev sib cuag metamorphism yog metamorphic pob zeb marbleMarble yog tsim los ntawm limestone uas tau raug tshav kub. Lub cheeb tsam metamorphism los ntawm qhov sib txawv tshwm sim nyob rau thaj chaw loj thiab yog qib siab metamorphism. … Nws feem ntau yog pob zeb metamorphic hu ua gneiss.
