Koj tuaj yeem txheeb xyuas cov ntxhia los ntawm nws cov tsos thiab lwm yam khoom . Cov xim thiab luster piav txog qhov zoo li ntawm a ntxhia , thiab streak piav txog cov xim ntawm cov hmoov ntxhia . Mohs hardness scale yog siv los sib piv cov hardness ntawm cov ntxhia.
Yog li, koj tuaj yeem txheeb xyuas cov ntxhia los ntawm nws cov khoom li cas?
Cov khoom uas pab geologists txheeb xyuas cov ntxhia Nyob rau hauv ib lub pob zeb yog: xim, hardness, luster, crystal forms, ceev, thiab cleavage. Crystal form, cleavage, thiab hardness yog txiav txim siab los ntawm tus siv lead ua qauv ntawm tus qib atomic. Xim thiab ntom yog txiav txim siab los ntawm tus tshuaj muaj pes tsawg leeg.
Qhov thib ob, vim li cas ntau dua ib qho cuab yeej feem ntau siv los txheeb xyuas cov pob zeb tsis paub? Streak yog xim ntawm tus ntxhia nyob rau hauv hmoov daim ntawv. Vim yog streak a ntau ua piv txwv tseeb ntawm tus cov ntxhia xim, streak yog ib ntau ntseeg tau cov cuab yeej ntawm minerals dua xim rau kev txheeb xyuas . Hardness. Hardness yog ib of zoo dua cov khoom ntawm minerals siv rau kev txheeb xyuas a ntxhia.
Tom qab ntawd, 8 txoj hauv kev los txheeb xyuas cov ntxhia li cas?
Siv cov yam ntxwv ntawm Minerals los txheeb xyuas lawv. Feem ntau cov zaub mov tuaj yeem ua tus yam ntxwv thiab cais los ntawm lawv lub cev tshwj xeeb: tawv , luster , xim , streak , tshwj xeeb lub ntiajteb txawj nqus, cleavage, tawg, thiab tenacity.
Yam khoom twg yog qhov tseem ceeb tshaj plaws hauv kev txheeb xyuas cov ntxhia?
Xim , luster, streak , tawv , cleavage, tawg, thiab siv lead ua daim ntawv yog lub cev muaj txiaj ntsig zoo tshaj plaws rau kev txheeb xyuas cov zaub mov feem ntau. Lwm yam khoom-xws li cov tshuaj tiv thaiv acid, hlau nplaum, tshwj xeeb lub ntiajteb txawj nqus , tenacity, saj, tsw, hnov, thiab muaj striations-yog pab tau nyob rau hauv kev txheeb xyuas tej yam minerals.
