Pob zeb yog ib tug natural khoom tsim ntawm ib los yog ntau minerals tsim ntau lab xyoo dhau los ntawm kev nyuaj siab. Theminerals hauv pob zeb tuaj ntawm tib cov kua thiab roj mineralshat tsim lub ntiaj teb. Raws li lub crust tau thicker, nws squeezedaround lub puab core uas tsim mob siab heev thiab kub los ntawm nyob rau hauv lub ntiaj teb.
Ib yam li ntawd, pob zeb tau tsim li cas?
Tau ntau lab xyoo, kev sib xyaw ua ke ntawm cov cua sov thiab kev kub ntxhov tsim blocks ntawm ntuj pob zeb , suav nrog granite, marble, travertine, limestone, thiab slate. Raws li lub ntiaj teb daim tawv nqaij pib loj hlob thiab erode, nws thawb cov minerals los ntawm nws cov tub ntxhais, tsim loj pob zeb deposits, uas peb hu ua "quarries".
Kuj Paub, pob zeb yog dab tsi thiab lawv tsim li cas? Lawv yog cov nplej me me ntawm cov zaub mov sib txawv, compressed ua ke hauv cov tshuaj tiv thaiv rau daim ntawv loj dua. Pob zeb ua ib feem uas tsis yog dej ntawm lub ntiaj teb daim tawv nqaij.
Qhov sib thooj, cov pob zeb ua los ntawm dab tsi?
Lub ntiaj teb yog npog rau hauv ib txheej ntawm cov pob zeb uas hu ua thecrust. Pob zeb yog SEDIMENTARY, IGNEOUS, los yog METAMOPHIC. Yuav luag tag nrho pob zeb ua ntawm minerals, butdifferent pob zeb muaj cov sib txawv ntawm cov ntxhia pob zeb. Granite, piv txwv li, muaj quartz, feldspar, andmica.
Dab tsi yog ntuj pob zeb?
Ntuj pob zeb Cov khoom no suav nrog Granite, Marble, Limestone, Travertine, Slate, Quartzite, Sandstone, Adoquin, Onyx, thiab lwm yam.

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
Lub pob zeb twg loj dua pob zeb?
Sedimentary pob zeb tuaj yeem ua los ntawm cobbles. Cobbles yog pob zeb uas loj dua pebbles tab sis me dua pob zeb. Conglomerate thiab breccia yog
Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
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
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
