Qhov no feem ntau tshwm sim tob hauv lub ntiaj teb los yog ze ntawm magma hauv av. Peb feem ntau nrhiav cov pob zeb metamorphic nyob rau hauv roob qhov twg high pressures squeezed lub pob zeb ua ke thiab lawv piled mus daim ntawv thaj tsam xws li Himalayas, Alps, thiab Rocky Roob.
Ib yam li ntawd, koj tuaj yeem nug, qhov twg koj yuav xav tias yuav pom cov pob zeb tsis muaj zog thiab cov pob zeb metamorphic?
Igneous - lawv tsim los ntawm qhov txias ntawm magma tob hauv lub ntiaj teb. Lawv feem ntau muaj cov muaju loj (koj tuaj yeem ua tau saib lawv nrog qhov muag liab qab). Metamorphic - lawv yog tsim los ntawm kev hloov pauv (metamorphosis) ntawm igneous thiab sedimentary pob zeb . Lawv tuaj yeem tsim ob qho tib si hauv av thiab ntawm qhov chaw.
Ib yam li ntawd, qhov twg koj yuav pom kev sib cuag metamorphism? Hu rau metamorphism tshwm sim feem ntau nyob ib ncig ntawm intrusive igneous pob zeb raws li qhov tshwm sim ntawm qhov kub thiab txias tshwm sim los ntawm intrusion ntawm magma rau hauv lub teb chaws txias pob zeb. Qhov chaw nyob ib puag ncig ntawm kev nkag mus rau qhov twg tiv tauj metamorphism teebmeem yog tam sim no yog hu ua metamorphic aureole.
Tsis tas li ntawd, lub pob zeb metamorphic ua li cas?
Cov pob zeb metamorphic los ntawm tshav kub thiab siab hloov tus thawj los yog niam txiv pob zeb mus rau hauv ib tug kiag li tshiab pob zeb . Niam txiv pob zeb tuaj yeem yog sedimentary, igneous, lossis lwm yam metamorphic pob zeb . Lo lus " metamorphic "los ntawm Greek thiab txhais tau tias "To Change Daim ntawv ".
Koj tuaj yeem txheeb xyuas lub pob zeb metamorphic li cas?
Metamorphic pob zeb yog pob zeb uas tau hloov los ntawm kev kub siab los yog siab thaum tsim. Ib txoj kev mus qhia yog tias a pob zeb qauv yog metamorphic yog saib seb cov crystals nyob rau hauv nws yog teem nyob rau hauv bands. Piv txwv ntawm metamorphic pob zeb yog marble, schist, gneiss, thiab slate.

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
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
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
Cov pob zeb hauv av twg tuaj yeem tsim cov pob zeb zoo li lub raum?
Hematite (los yog haematite) Kuj tseem muaj ntau hom hematite, qee yam yog: raum ore, ib qho loj, botryoidal (lumpy) lossis reniform (lub raum zoo li tus) daim ntawv; specularite, micaceous (flaky) daim ntawv; oolitic, ib daim ntawv sedimentary tsim los ntawm cov nplej me me; liab ochre, ib daim ntawv liab earthy
Lub pob zeb foliated twg yog qhov qis tshaj plaws metamorphic pob zeb?
slate Ua li no, marble puas yog qib qis metamorphic pob zeb? Qee qhov piv txwv ntawm non-foliated Cov pob zeb metamorphic yog marble , quartzite, thiab hornfels. Marble yog metamorphosed limestone. Thaum nws tsim, cov calcite crystals yuav loj hlob tuaj, thiab tej yam sedimentary textures thiab fossils uas muaj tam sim no raug puas tsuaj.
