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?
Kuj, thaum xav txog qhov tsos, calcite tshwm sim nyob rau hauv cov xim sib txawv xws li grey, daj lossis ntsuab, qhov halite feem ntau tshwm sim hauv cov xim sib txawv xws li lub teeb xiav, tsaus xiav, ntshav, liab, liab., txiv kab ntxwv, daj thiab grey.
Qhov kev kuaj pom pob zeb twg koj yuav siv los paub qhov txawv calcite thiab halite?
Saj - Taste tuaj yeem siv los pab txheeb xyuas qee cov zaub mov, xws li halite (ntsev). Cov tshuaj tiv thaiv acid - Cov khoom ua rau hydrochloric acid. Qhov txawv tshaj plaws yam ntxwv ntawm calcite yog tias nws effervesces thaum siv hydrochloric acid. Dolomite qhia tau hais tias muaj qhov tshwm sim ntawm qhov tawg tshiab lossis hmoov av.
Koj paub halite li cas?
Halite
- Shape: Isometric (crystals feem ntau zoo li lub voos xwmfab)
- Luster: Glassy.
- Xim: Ntshiab, dawb, pinkish, lossis grey.
- Steak: Dawb.
- Hardness: 2.5 ntawm Mohs Hardness Scale.
- Cleavage: 3 lub dav hlau ntawm kev sib tw zoo meej.
- Fracture:Conchoidal.
pob zeb twg yog halite pom nyob hauv?
Halite tshwm sim nyob rau hauv pob zeb sedimentary qhov uas nws tau tsim los ntawm evaporation ntawm seawater los yog dej qab ntsev pas dej. Cov txaj loj ntawm cov dej ntxhia evaporite, suav nrog halite, tuaj yeem tshwm sim los ntawm kev ziab ntawm cov pas dej, thiab cov hiav txwv txwv.
