Metamorphic Pob Zeb . Metamorphic pob zeb yog ib zaug igneous los yog sedimentary pob zeb , tab sis tau hloov pauv ( metamorphosed ) raws li qhov tshwm sim ntawm kev kub ntxhov thiab / lossis siab nyob rau hauv lub ntiaj teb lub pob zeb. Lawv yog crystalline thiab feem ntau muaj "squashed" (foliated los yog banded) zoo nkauj.
Ib yam li ntawd, tib neeg nug, ua li cas koj thiaj paub lub pob zeb metamorphic?
Metamorphic pob zeb yog pob zeb uas tau hloov los ntawm kev kub siab los yog siab thaum tsim. Ib txoj kev 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.
Ib yam li ntawd, cov piv txwv ntawm cov pob zeb metamorphic yog dab tsi? Piv txwv ntawm cov pob zeb metamorphic muaj xws li anthracite, quartzite, marble, slate, granulite, gneiss thiab schist. Anthracite yog ib hom thee nrog ib tug siab carbon suav, ob peb impurities thiab nrog ib tug siab luster (lub ntsiab lus nws zoo li ci iab). Marble yog lub pob zeb metamorphic uas yog tsim los ntawm cov pob zeb sedimentary limestone.
Tsis tas li ntawd, cov pob zeb metamorphic zoo li cas thiab zoo li cas?
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. Tsis-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite ua tsis muaj txheej txheej los yog banded tsos.
Foliated metamorphic pob zeb yog dab tsi?
Foliated Metamorphic Pob Zeb . Foliated metamorphic pob zeb yog tsim nyob rau hauv lub ntiaj teb sab hauv nyob rau hauv tsis tshua muaj siab pressures uas tsis sib xws, tshwm sim thaum lub siab yog ntau dua nyob rau hauv ib qho kev taw qhia tshaj nyob rau hauv lwm yam (qhia siab).

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.
