Yuav cov carnelian ntuj hauv peb lub khw


Carnelian yog ib qho tseeb rau translucent reddish-xim av ntau ntawm chalcedony. Nws hue yuav txawv ntawm lub txiv kab ntxwv daj ntseg, rau qhov yuav luag dub xim. Zoo li lub carnelian yog sard, uas yog xim av es liab.

Zoo sib xws rau carnelian yog sard, uas feem ntau nyuaj thiab ib tsos tsaus tsawv. Qhov txawv tsis yog rigidly txhais. Peb tuaj yeem siv ob lub npe sib hloov. Ob lub carnelian thiab sard yog ntau hom ntawm silica pob zeb hauv av chalcedony. Nws s xim los ntawm impurities ntawm hlau oxide. Cov xim muaj peev xwm sib txawv heev, xws li daj ntseg txiv kab ntxwv rau qhov sib luag ntawm cov xim dub.

Chalcedony quartz

Ib daim ntawv microcrystalline ntawm silica, tsim ntawm cov kev sib txuam zoo heev ntawm quartz thiab moganite. Cov no yog ob qho tib si cov tshuaj ntxhia silica, tab sis lawv txawv hauv qhov quartz muaj cov qauv tsim qauv siv lead ua, thaum moganite yog monoclinic. Nws tus qauv tshuaj qauv, raws li cov qauv tshuaj lom neeg ntawm quartz, yog silicon dioxide.

Chalcedony muaj lub zeem muag thiab yuav yog semitransparent lossis translucent. Nws muaj peev xwm xav ntau yam xim, tab sis cov neeg feem ntau pom muaj dawb dawb gray, grayish xiav los yog ib qho ntxoov ntxoo ntawm xim av xws li daj ntseg mus ze li dub. Ntau lub pob zeb muag hauv kev lag luam tau ua rau kev kho mob los ntawm cua los yog cua kub kom hloov xim.

Chalcedony yog ib zaug xav tias yuav tsum muaj ntau hom cryptocrystalline quartz fibrous. Nyuam qhuav tsis ntev los no, peb pom tias nws kuj muaj ib qho monoclinic polymorph ntawm quartz. Nws paub li moganite. Cov feem, ntawm pawg, ntawm moganite nyob rau hauv cov qauv raug chalcedony yuav txawv ntawm tsawg dua 5% mus tshaj 20%. Lub neej ntawm moganite yog ib zaug saib raws li dubious. Tab sis nws yog tam sim no paub los ntawm International Mineralogical Association.

Chalcedony yog ntau soluble dua crystalline quartz nyob rau hauv qis kub, txawm ob cov zaub mov ua sib xws tib yam. Qhov no yog xav tau vim hais tias chalcedony yog tsis tshua muaj ntsis grained cryptocrystalline. Thiab yog li muaj ib thaj chaw siab heev rau ntim piv. Nws zoo nkaus li tias qhov ntau dua solubility yog vim muaj cov tshuab moganite.
