Keeb Kwm tsim los ntawm crystallization los ntawm magma lossis hauv cov pob zeb metamorphic, zircons yog qhov ruaj khov thiab tiv taus tshuaj tua kab mob uas lawv tsis tshua ploj mus. Lawv tuaj yeem muaj sia nyob ntau qhov xwm txheej geological, uas tuaj yeem sau rau hauv cov nplhaib ntawm zircon ntxiv uas loj hlob nyob ib puag ncig cov khoom siv lead ua qub zoo li cov nplhaib ntoo.
Zircons tuaj qhov twg?
Zircon tau pom thoob plaws ntiaj teb, tab sis lub pov haum zoo nkauj tsis tshua muaj. Sri Lanka thiab Southeast Asia yog thawj qhov chaw ntawm lub pov haum zoo zircons. Sri Lanka tsim cov khoom nyob rau hauv tag nrho cov xim nyob rau hauv gravels, nrog rau tsawg tus miv lub qhov muag. Cambodia yog qhov tseem ceeb ntawm cov khoom siv cua sov ua kom tsis muaj xim thiab xiav.
Zircon ua li cas?
Zircon, tseem hu ua zirconium silicate (ZrSiO 4), yog ib qho khoom lag luam los ntawm kev mining thiab ua cov ntxhia pob zeb hnyav thaum ub . … Zircon tuaj yeem ua tiav los tsim zirconia los ntawm melting cov xuab zeb ntawm qhov kub siab heev los ua zirconia molten, los yog zirconium oxide (ZrO2).
Thaum twg zircon tsim?
Nyob rau xyoo 1789, thaum soj ntsuam cov muaj pes tsawg leeg ntawm zircon Martin Heinrich Klaproth, German chemist nrhiav pom zirconium. Cov hlau no tau raug cais tawm ntawm zircon los ntawm Jöns Jacob Berzelius, kws tshuaj Swedish, hauv 1824.
Zircon crystals nyob qhov twg?
Zircon is common in the crust of Earth. Nws tshwm sim raws li ib qho khoom siv pob zeb hauv cov pob zeb tsis pom kev (raws li cov khoom siv crystallization), hauv cov pob zeb metamorphic thiab ua cov nplej detrital hauv cov pob zeb sedimentary. Loj zircon crystals tsis tshua muaj.
