Halite thiab calcite yog ob qho tib si dawb kom meej, tab sis muaj qhov sib txawv cleavages thiab crystal shapes. Halite muaj cubic cleavage tsim cov ntxhia nrog cov duab ntawm lub voos xwmfab. Calcite muaj peb cleavage cov lus qhia, tab sis tsis nyob ntawm 90 degrees yog li cov pob zeb hauv av muaj cov duab rhombic. Halite kuj muaj qab ntsev, thaum calcite tsis.
Dab tsi yog ob txoj hauv kev yooj yim kom paub qhov txawv ntawm calcite thiab halite?
