Metamorphic Pob Zeb vs Sedimentary Pob Zeb
Pob zeb hauv lub ntiaj teb lub pob zeb tuaj yeem faib ua ntau yam hauv peb hom. Cov pob zeb loj no yog pob zeb tsis muaj zog, pob zeb sedimentary, thiab cov pob zeb metamorphic. Geologist ua qhov kev faib tawm no raws li cov txheej txheem geological, uas tsim cov pob zeb muab. Igneous pob zeb yog tsim thaum melted pob zeb txias thiab solidify. Sedimentary pob zeb yog tsim thaum sediments tau solidified. Cov pob zeb metamorphic yog cov pob zeb uas tau hloov los ntawm cov pob zeb tsis muaj zog lossis cov pob zeb metamorphic. Zoo li lub voj voog dej, muaj lub voj voog pob zeb (geological voj voog) hauv geology. Lub voj voog pob zeb txhais tau hais tias cov txheej txheem los ntawm cov pob zeb tsim, degraded thiab hloov kho los ntawm cov txheej txheem hauv geological xws li plutonism, volcanism, uplift thiab / lossis los ntawm cov txheej txheem geological sab nraud xws li yaig, huab cua, deposition, thiab lwm yam. Raws li lub voj voog pob zeb ib hom pob zeb tuaj yeem hloov mus rau lwm qhov (ob qho ntawm ob hom). Tawm ntawm qhov ntim ntawm sab nraud 16kms ntawm lub ntiaj teb crust, 95% yog cov pob zeb tsis zoo thiab 5% yog ua los ntawm cov pob zeb sedimentary. Nco ntsoov tias ntawm no cov pob zeb metamorphic suav nrog ib qho ntawm cov qeb raws li lawv cov hom pob zeb qub, uas yog, yog tias nws yog los ntawm lub hauv paus chiv keeb ces suav tias yog nyob rau hauv cov pob zeb tsis muaj zog
Sedimentary pob zeb
Pob zeb tau tawg mus rau hauv cov khoom me me vim cov huab cua huab cua xws li cua, dej, thiab lwm yam. Cov khoom me me no hu ua sediments. Cov sediments tau deposited los ntawm ntau yam mechanisms. Cov sediments tsim cov txheej nyias nyias. Tom qab ntawd cov khaubncaws sab nraud povtseg yuav nyuaj rau lub sijhawm ntev. Cov txheej tawv tawv ntawm sediments yog hu ua sedimentary pob zeb. Kev ntxhib los mos ntawm cov pob zeb sedimentary qhia txog hom sediment deposition thiab tom qab huab cua. Sedimentary pob zeb yog ib qho yooj yim los txheeb xyuas raws li cov txheej txheem pom. Feem ntau cov pob zeb sedimentary yog tsim nyob rau hauv dej (hiav txwv). Sedimentary pob zeb feem ntau muaj qhov pores li lawv tsim los ntawm sediments. Shale, sandstone, limestone, conglomerate, thiab thee yog ib co piv txwv rau cov pob zeb sedimentary. Cov pob zeb no feem ntau yog nplua nuj nyob rau hauv fossils. Fossils yog qhov seem ntawm cov tsiaj thiab nroj tsuag, khaws cia hauv pob zeb. Sedimentary pob zeb muaj ntau yam xim.
Metamorphic Rocks
Metamorphic pob zeb yog tsim los ntawm metamorphism los ntawm cov pob zeb uas twb muaj lawm lossis cov pob zeb sedimentary lossis txawm los ntawm cov pob zeb metamorphic uas twb muaj lawm. Thaum cov pob zeb uas twb muaj lawm raug hloov pauv vim qhov kub siab thiab / lossis kub thiab / lossis siab shearing stresses, metamorphic pob zeb yog tsim. Feem ntau cov pob zeb metamorphic tau tsim tob hauv lub ntiaj teb. Thaum tshav kub kub los ntawm magma, thaum lub siab los ntawm txheej ntawm pob zeb nyob rau sab saum toj ntawm lwm txheej. Cov pob zeb metamorphic yog cais raws li foliation li foliated pob zeb thiab cov pob zeb uas tsis yog foliated. Foliation txhais tau hais tias muaj nyob ntawm series ntawm parallel nto. Cov pob zeb no feem ntau muaj siv lead ua. Gneiss, slate, marble, thiab quartzite yog qee cov pob zeb metamorphic.
Dab tsi yog qhov txawv ntawm Metamorphic Pob Zeb thiab Sedimentary Pob Zeb?
pob zeb sedimentary thiab metamorphic pob zeb muaj qee qhov sib txawv ntawm lawv.
– Tsim cov pob zeb metamorphic tuaj yeem cuam tshuam nrog cov cua sov los ntawm magma, thaum nws tsis yog nrog cov pob zeb sedimentary.
– Sedimentary pob zeb yog tsim nyob rau hauv lub ntiaj teb nto, thaum metamorphic pob zeb yog tsim nyob rau hauv lub ntiaj teb.
– Cov pob zeb sedimentary feem ntau muaj cov pob txha, thaum cov pob zeb metamorphic tsis tshua muaj pob txha.
– Sedimentary pob zeb feem ntau muaj qhov pores ntawm daim, tab sis cov pob zeb metamorphic tsis tshua muaj qhov hws lossis qhib.
– Cov pob zeb metamorphic tej zaum yuav muaj qhov nkhaus lossis nkhaus foliation, thaum cov pob zeb sedimentary feem ntau muaj txheej.
– Cov pob zeb metamorphic nyuaj dua li pob zeb sedimentary.
