Muscovite yog cov ntxhia tshaj plaws ntawm cov mica tsev neeg. Nws yog ib qho tseem ceeb ntawm cov pob zeb tsim cov pob zeb uas muaj nyob hauv cov pob zeb tsis zoo, metamorphic, thiab sedimentary pob zeb. Zoo li lwm yam micas nws nkag cleaves rau hauv nyias pob tshab ntawv. Muscovite Cov nplooj ntawv muaj pearly rau vitreous luster ntawm lawv qhov chaw.

Hais txog qhov no, qhov txawv ntawm Mica thiab Muscovite yog dab tsi?

Cov mica cov zaub mov muaj ib qho zoo meej cleavage uas tso cai rau lawv tawg mus rau hauv nyias nyias. Qhov no yog qhov txawv heev. Muscovite yog ntshiab, silvery, los yog coppery silver nyob rau hauv cov xim (nyob ntawm seb lub thickness ntawm cov qauv thiab muaj impurities) whereas tshiab biotite yog dub.

Tom qab, lo lus nug yog, qhov twg muscovite mica pom? Muscovite feem ntau tshwm sim hauv cov pob zeb metamorphic, tshwj xeeb tshaj yog gneisses thiab schists, qhov twg nws tsim muaju thiab daim hlau. Nws kuj tshwm sim nyob rau hauv granites, nyob rau hauv nplua-grained sediments, thiab nyob rau hauv ib co siliceous pob zeb. Loj crystals ntawm muscovite feem ntau pom nyob rau hauv cov hlab ntsha thiab pegmatites.

Kuj paub, dab tsi yog muscovite mica siv rau?

Nws yog siv li iav vim nws cov pob tshab txheej uas tev tawm hauv cov ntawv nyias. Nws kuj yog siv nyob rau hauv qhov cub qhov rooj. Muscovite yog nyob rau hauv kev thov rau kev tsim khoom ntawm fireproofing thiab insulating cov ntaub ntawv thiab rau ib co raws li ib tug lubricant.

Dab tsi yog qhov hardness ntawm muscovite mica?

Muscovite muaj Mohs tawv ntawm 2–2.25 parallel mus rau [001] lub ntsej muag, 4 perpendicular mus rau [001] thiab ib tug tshwj xeeb gravity ntawm 2.76–3. Nws tuaj yeem yog xim tsis muaj xim lossis tinted los ntawm greys, xim av, ntsuab, daj, lossis (tsis tshua muaj) violet lossis liab, thiab tuaj yeem pob tshab lossis translucent. Nws yog anisotropic thiab muaj siab birefringence.
