Hom ntawm Garnet

Muaj ntau hom thawj cov ntaub qhwv hauv ntshav liab, feem ntau nyob hauv cov pob zeb magmatic lossis metamorphic, feem ntau ntawm lub pov haum-qib garnet pom nyob rau hauv cov alluvial xuab zeb. Hniav ntshav hniav yog cov pob zeb hauv av nplaum, yog ntau cov tshuaj lom neeg muaj pes tsawg leeg ntawm silicate minerals (island silicate), feem ntau hais hauv a3b2 [sio4] 3. Qhov twg yog qhov piv txwv ca2 +, mg2 +, fe2 +, mn2 + thiab lwm yam khoom siv ob tus nqi, b txhais tau hais tias al3 +, fe3 +, cr3 + thiab lwm yam khoom muaj nqis. Lub morphology siv lead ua yog ib lub cev uas muaj 12-sided lub cev, ib lub kaum plaub lub kaum ntse ntse los yog ib lub cev ntawm ob qho tib si. Lub rooj sib txoos yog hnyav lossis lumpy. Cov xim ntawm garnet yog pawg los ntawm cov khoom xyaw thiab nthuav tawm ntau yam xim, nrog rau xim liab 'ntshav liab' liab txiv kab ntxwv; Cov xim daj muaj xws li daj 'daj txiv kab ntxwv' daj daj daj; thiab cov koob ntsuab muaj xws li cov lus cog tseg 'txiv ntseej ntsuab' daj ntsuab. Crystal Surface zaub iav ci iab, los ntawm King Kong Luster, tawg ntawm cov roj lee. Pob tshab rau translucent. Homogenous lub cev, tsis multicolor, tsis muaj phenomenon birefringence. Garnet tuaj yeem muab faib ua ob kab, 6 yam loj: Iron thiab Aluminium Garnet series (magnesium aluminium garnet, aluminium garnet, manganese aluminium garnet) thiab Calcium Iron Garnet series (Calcium chrome garnet, calcium aluminium garnet, calcium hlau garnet).
