Serpentinite yog metamorphic pob zeb uas yog feem ntau tsim ntawm serpentine pawg minerals. Serpentine pawg minerals antigorite, lizardite, thiab chrysotile yog tsim los ntawm hydrous alteration ntawm ultramafic pob zeb . Cov no yog igneous pob zeb uas yog tsim olivine thiab pyroxene (peridotite, pyroxenite).
Ib yam li ntawd ib tug yuav nug, ua li cas serpentine pob zeb tsim?
Serpentinites thiab Serpentine Tsim Serpentine minerals tsim qhov twg peridotite, dunite, thiab lwm yam ultramafic pob zeb Ua raws li hydrothermal metamorphism. Lawv yog metamorphosed ntawm convergent phaj ciam teb qhov twg ib tug dej hiav txwv phaj yog thawb mus rau hauv lub mantle.
Ib yam li ntawd, serpentine pob zeb siv rau dab tsi? Cov serpentine subgroup (ib feem ntawm kaolinite- serpentine pawg) yog cov zaub ntsuab, xim av, lossis pom cov zaub mov uas muaj nyob hauv serpentinite pob zeb . Lawv yog siv li ib qhov chaw ntawm magnesium thiab asbestos, thiab ua lub pob zeb zoo nkauj. Lub npe xav tias los ntawm cov xim ntsuab yog cov nab.
Ua li no, serpentine pob zeb puas txaus ntshai?
Serpentine tsis yog tshuaj lom pob zeb . Qee lub sij hawm nws muaj cov ntxhia pob zeb chrysotile asbestos, tab sis chrysotile asbestos tsis yog daim ntawv ntawm asbestos uas muaj pov thawj ua rau mesothelioma thiab mob ntsws cancer. Cov pob zeb kuj zoo nkauj heev, rau qhov no geologist lub qhov muag. Nws txawv ntawm cov xim ntawm dub mus rau khaus jade-ntsuab.
Dab tsi ntawm pob zeb yog serpentine?
Serpentine yog lub pov haum zoo hydrated magnesium silicate, feem ntau yog ntsuab, daj-ntsuab, los yog brownish-ntsuab nyob rau hauv cov xim. Nws lub npe yog xav tau los ntawm nws cov nab zoo li ntsuab xim. Serpentine tsis yog tsuas yog lub pov haum xwb, tab sis, nws yog ib pawg ntawm cov zaub mov uas suav nrog txog 20 tus tswv cuab sib txawv.

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
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"
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
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
Dab tsi ntawm pob zeb ua rau ib qho chaw pob zeb?
