Qhov ntxeev lus yog anhedral (tseem hu ua xenomorphic lossis allotriomorphic): lub pob zeb uas muaj kev ntxhib los mos yog tsim los ntawm cov ntxhia pob zeb uas tsis muaj lub ntsej muag zoo nkauj siv lead ua los yog cov duab ntoo khaub lig hauv ntu nyias. … Yog li, snowflakes daim ntawv euhedral, rau-sided twinned crystals.
Puas yog cov ntxhia crystalline?
Txhua yam minerals, los ntawm txhais yog kuj muaju. Kev ntim cov atoms hauv cov qauv siv lead ua yuav tsum tau ua kom zoo thiab rov ua dua atomic. Xws li kev npaj yuav tsum tau ua kom tiav qhov chaw zoo thiab khaws tus nqi sib npaug.
Qhov txawv ntawm anhedral thiab euhedral yog dab tsi?
Euhedral cov zaub mov qhia zoo meej lossis ze li lub ntsej muag zoo meej. Subhedral minerals yog sib npaug tab sis tseem qhia cov yam ntxwv ntawm cov pob zeb hauv av. Anhedral crystals yog qhov tsis sib xws hauv cov duab thiab tsis zoo li tus yam ntxwv daim ntawv rau cov ntxhia.
pob zeb diamond crystallization yog dab tsi?
A geode yog ib lub pob zeb sib npaug, hollow pob zeb uas feem ntau lined nrog cov pob zeb hauv av. Nws yog tsim nyob rau hauv txoj kev uas tag nrho cov minerals feem ntau yog tsim-los ntawm crystallization, txheej txheem los ntawm cov atoms yog teem los tsim ib cov khoom siv lead ua qauv. … Thaum cov kua no txias mus rau ib lub xeev khov, lawv tsim muaju.
txhais li cas los ntawm anhedral siv lead ua?
anhedral (allotriomorphic) Lub sij hawm morphological xa mus rau grains hauv pob zeb tsis pomuas tsis muaj crystalline zoo li qub. Anhedral cov ntaub ntawv yog tsim los thaum ib tug crystal dawb kev loj hlob nyob rau hauv ib tug yaj yog inhibited los ntawm lub xub ntiag ntawm ib puag ncig crystals.
