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 yog - foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite ua tsis yog muaj txheej txheej los yog banded tsos.
Yog li ntawd, dab tsi yog cov pob zeb tsis foliated metamorphic?
Tsis yog - foliated metamorphic pob zeb tshwm loj los yog granular yam tsis muaj cov yam ntxwv thaum uas tig mus ntxhia nplej hauv foliated pob zeb . Tsis yog - foliated metamorphic pob zeb raug cais raws li lawv qhov muaj pes tsawg leeg. Marble, quartzite, thiab soapstone yog cov piv txwv ntawm tsis yog - foliated metamorphic pob zeb.
Tsis tas li ntawd, cov pob zeb foliated thiab Nonfoliated muaj dab tsi? Hauv cov ntsiab lus yooj yim heev, Foliation tsim los ntawm kev ua haujlwm siab. Yog li foliated pob zeb feem ntau yog Metamorphic pob zeb (qib qis). Non-foliated pob zeb ntawm qhov tod tes yog ib lo lus dav dav heev, nws tuaj yeem suav nrog txhua yam pob zeb (tej zaum nws yuav yog sedimentary, igneous los yog metamorphic).
Tom qab ntawd, dab tsi yog foliated metamorphic pob zeb?
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).
Ob tug yam ntxwv ntawm Nonfoliated metamorphic pob zeb yog dab tsi?
Nonfoliated Metamorphic Pob Zeb
- Nonfoliated metamorphic pob zeb yog tsim nyob ib ncig ntawm igneous intrusion qhov twg qhov kub thiab txias tab sis cov pressures kuj tsis tshua muaj thiab sib npaug nyob rau hauv tag nrho cov lus qhia (confining siab).
- Quartzite = muaj cov ntxhia quartz; metamorphosed sandstone.
- Marble = muaj cov ntxhia calcite; metamorphosed limestone.

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
Cov piv txwv ntawm cov pob zeb tsis foliated metamorphic yog dab tsi?
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 sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
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
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.
