Luster tsuas yog ib daim ntawv tseem ceeb ntawm kev txheeb xyuas cov ntxhia thaum cov qauv hauv nqe lus nug qhia txog qhov tshwj xeeb luster , xws li waxy, greasy, pearly, thiab lwm yam. Cov qauv nrog ib lub vitreous luster tsis tuaj yeem paub qhov txawv ntawm ib leeg, tsis tuaj yeem cov ntxhia nrog ib tug metallic luster.
Tsis tas li ntawd, Luster siv los txheeb xyuas cov zaub mov li cas?
Luster piav txog qhov kev xav ntawm lub teeb tawm a cov ntxhia nto. Mineralogists muaj cov ntsiab lus tshwj xeeb los piav qhia luster . Ib txoj hauv kev yooj yim los faib luster yog nyob ntawm seb cov ntxhia yog metallic los yog non-metallic. Cov ntxhia uas yog opaque thiab ci, xws li pyrite, muaj hlau luster.
Ib yam li ntawd, Luster ntawm ib qho ntxhia yog dab tsi? Luster (British English) los yog luster (American English; saib qhov sib txawv ntawm kev sau ntawv) yog txoj kev lub teeb cuam tshuam nrog lub ntsej muag ntawm lub ntsej muag, pob zeb, lossis ntxhia . Ntau cov ntsiab lus yog siv los piav qhia luster , xws li earthy, metallic, greasy, thiab silky.
Kuj Paub, vim li cas luster tseem ceeb rau kev txheeb xyuas cov ntxhia?
Piav: Lub luster ntawm a ntxhia yog txoj kev uas nws reflects lub teeb. Cov ntxhia uas yog ci ntsa iab zoo li pob zeb diamond muaj adamantine luster . Nrog me ntsis kev xyaum, luster yog ib qho yooj yim lees paub raws li xim thiab tuaj yeem sib txawv heev, tshwj xeeb tshaj yog rau cov ntxhia uas tshwm sim nyob rau hauv ntau yam xim zoo li quartz.
Dab tsi yog cov piv txwv ntawm cov kev ntsuam xyuas uas tuaj yeem siv rau kev txheeb xyuas cov ntxhia?
Geologists siv cov hauv qab no kuaj kom paub qhov txawv cov ntxhia thiab cov pob zeb lawv ua: hardness, xim, streak, luster, cleavage thiab tshuaj tiv thaiv. Ib qho kos xeem tsim los ntawm German mineralogist Fredriech Mohs nyob rau hauv 1822 yog siv los txiav txim ntxhia tawv.

Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Koj puas tuaj yeem txheeb xyuas cov ntxhia los ntawm ib qho khoom xwb?
Koj tuaj yeem txheeb xyuas cov ntxhia los ntawm nws cov tsos thiab lwm yam khoom. Cov xim thiab luster piav txog cov tsos ntawm cov ntxhia, thiab streak piav txog cov xim ntawm cov hmoov ntxhia. Mohs hardness scale yog siv los sib piv cov hardness ntawm minerals
Puas yog qhov ceev yog ib txoj kev txhim khu kev qha ntawm kev txheeb xyuas tag nrho cov khoom tsis paub?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub los ntawm kev ntsuas nws qhov ntom thiab sib piv koj cov txiaj ntsig rau cov npe paub qhov ntom ntom. Qhov ntom = loj / ntim. Xav tias koj yuav tsum txheeb xyuas cov hlau tsis paub. Koj tuaj yeem txiav txim siab qhov loj ntawm cov hlau ntawm qhov ntsuas
Yuav ua li cas koj txheeb xyuas cov kev sib txuas ntxiv thiab cov kab ntsug?
Cov kaum sab xis yog ob lub kaum sab xis nrog qhov sib npaug ntawm 90º. Cov ces kaum ntxiv yog ob lub kaum sab xis nrog qhov sib npaug ntawm 180º. Vertical angles yog ob lub kaum sab xis uas nws ob sab tsim ob khub ntawm opposite rays. Peb tuaj yeem xav txog cov no yog cov kaum sab xis uas tsim los ntawm X
Cov pob txha pob txha tau siv li cas los txhais thiab txheeb xyuas qhov kev faib tawm ntawm lub sijhawm geology?
Index fossils yog siv nyob rau hauv lub formal architecture ntawm geologic lub sij hawm rau txhais lub hnub nyoog, epochs, lub sij hawm, thiab eras ntawm lub sij hawm geological. Cov pov thawj rau cov xwm txheej no tau pom nyob rau hauv cov ntaub ntawv fossil nyob qhov twg muaj qhov ploj ntawm pawg loj ntawm cov tsiaj hauv ib lub sijhawm luv luv ntawm geologically
