Qhov chaw tshav kub muaj xws li magma, Geothermal cua sov, thiab kev sib txhuam ntawm faults. Qhov chaw siab muaj xws li qhov hnyav ntawm cov pob zeb overlying tob rau hauv lub ntiaj teb . Shear siab nyob rau hauv qhov chaw txhaum yuav metamorphose pob zeb ntawm qhov tob tob. Kev ua tshuaj lom neeg feem ntau yog tshwm sim los ntawm dej ntawm qhov kub thiab txias dua.
Tsis tas li ntawd nug, ua li cas cua sov cuam tshuam rau cov pob zeb metamorphic?
Igneous thiab sedimentary pob zeb ua metamorphic pob zeb raws li qhov tshwm sim ntawm khaus kub los ntawm magma thiab siab los ntawm tectonic hloov. Txawm tias cov pob zeb ua kub heev thiab nyob rau hauv ib tug loj deal ntawm lub siab nws ua tsis yaj. Yog tias pob zeb melted, txheej txheem yuav ua rau igneous, tsis metamorphic pob zeb.
Ib sab saum toj no, dab tsi yog hu rau metamorphic pob zeb? Hu rau metamorphism yog ib hom metamorphism uas cov pob zeb ntxhia thiab kev ntxhib los mos hloov pauv, feem ntau yog los ntawm tshav kub, vim tiv tauj nrog magma. Nov yog lub npe yooj yim kom nco qab yog tias koj nco qab cov no pob zeb hloov los ntawm qhov tseeb tuaj tiv tauj nrog ib yam dab tsi kub heev, zoo li magma.
Tsis tas li ntawd, cov pob zeb metamorphic sib cuag li cas?
Hu rau Metamorphism. Metamorphic pob zeb uas daim ntawv nyob rau hauv tej yam kev mob uas tsis tshua muaj siab los yog cia li confining siab tsis ua foliated. Feem ntau, qhov no yog vim lawv tsis faus tob, thiab cov cua sov rau lub metamorphism los ntawm lub cev ntawm magma uas tau tsiv mus rau sab sauv ntawm lub crust.
Puas yog cov pob zeb metamorphic tsim los ntawm tshav kub thiab siab?
Metamorphic pob zeb form thaum kub thiab siab hloov ib qho uas twb muaj lawm pob zeb rau hauv ib qho tshiab pob zeb . Kev sib cuag metamorphism tshwm sim thaum kub magma hloov pauv pob zeb uas nws hu. Regional metamorphism hloov cov cheeb tsam loj ntawm cov uas twb muaj lawm pob zeb nyob rau hauv qhov zoo kawg li kub thiab siab tsim los ntawm tectonic rog.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm - 12 m?
Kev piav qhia: Qhov kev txav ntawm ib qho khoom txav ntawm qhov chaw mus rau qhov chaw ntawm − 12 m yog 12 meters. Qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov siab tshaj plaws txoj hauj lwm yog hu ua displacement ntawm ib yam khoom. Qhov siab tshaj plaws kev hloov pauv ntawm cov khoom nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov pauv yog hu ua trough
Thaum tshav kub kub muaj peev xwm vs tshwj xeeb tshav kub yog dab tsi?
Molar Thaum tshav kub kub muaj peev xwm yog ib qho kev ntsuas ntawm cov cua sov uas tsim nyog los nce qhov kub ntawm ib mole ntawm ib tug ntshiab tshuaj los ntawm ib tug degree K. Tshwj xeeb kub muaj peev xwm yog ib qho kev ntsuas ntawm tus nqi ntawm cov cua sov tsim nyog los nce qhov kub ntawm ib gram ntawm ib tug ntshiab. khoom los ntawm ib degree K
Dab tsi yog cov pob zeb niam txiv ntawm cov pob zeb metamorphic?
Metamorphic pob zeb Metamorphic pob zeb Texture Niam txiv pob zeb Phyllite Foliated Shale Schist Foliated Shale, granite thiab volcanic pob zeb Gneiss Foliated Shale, granite thiab volcanic pob zeb Marble Nonfoliated Limestone, dolostone
