Hauv kev siv rau kev lag luam, granite yog qhov nrov heev rau nws qhov tawv, ruaj khov, zoo nkauj thiab lwm yam ntxwv. Txawm li cas los xij, muaj qee kis hauv kev ua lag luam uas cov khoom siv hloov marble raug xa mus ua granite. Tsuas yog los ntawm kev paub txog cov txheej txheem txheeb xyuas thiaj li xaiv tau granite zoo. Cov hauv qab no yog cov txheej txheem txheeb xyuas tshwj xeeb:
1. Saib cov yam ntxwv ntawm qhov tsos
Cov qauv thiab cov qauv: Cov qauv ntawm granite feem ntau yog cov pob zeb zoo sib xws thiab cov pob zeb me me, ua los ntawm cov khoom me me xws li quartz, feldspar, thiab mica, nthuav tawm cov ntsiab lus mica hnub qub thiab cov pob zeb quartz ci ntsa iab, nrog rau kev faib tawm sib xws. Cov qauv ntawm marble feem ntau tsis xwm yeem, feem ntau yog cov flakes, kab lossis strips, zoo li cov qauv ntawm cov duab kos duab toj roob hauv pes. Yog tias koj pom cov qauv nrog cov kab pom tseeb lossis cov qauv loj, nws yuav tsis yog granite. Tsis tas li ntawd, cov khoom me me ntawm cov granite zoo dua, qhov zoo dua, qhia txog cov qauv nruj thiab khov kho.
Xim: Cov xim ntawm granite feem ntau nyob ntawm nws cov khoom siv hauv cov pob zeb. Cov ntsiab lus ntawm quartz thiab feldspar ntau dua, cov xim sib dua, xws li cov koob greyish-dawb. Thaum cov ntsiab lus ntawm lwm cov zaub mov siab, cov granites greyish-dawb lossis grey series raug tsim. Cov uas muaj cov ntsiab lus potassium feldspar siab yuav tshwm sim liab. Cov xim ntawm marble yog cuam tshuam nrog cov zaub mov uas nws muaj. Nws tshwm sim ntsuab lossis xiav thaum nws muaj tooj liab, thiab liab dawb thaum nws muaj cobalt, thiab lwm yam. Cov xim nplua nuj thiab ntau yam. Yog tias cov xim ci dhau thiab tsis zoo li ntuj, nws yuav yog qhov hloov pauv dag rau kev zas xim.
II. Sim cov khoom siv lub cev
Qhov Nyuaj: Granite yog pob zeb tawv nrog Mohs hardness ntawm 6 txog 7. Qhov saum npoo tuaj yeem khawb maj mam nrog tus ntsia hlau hlau lossis tus yuam sij. Granite zoo yuav tsis tawm ib qho cim, thaum marble muaj Mohs hardness ntawm 3 txog 5 thiab yuav raug khawb ntau dua. Yog tias nws yooj yim heev rau khawb, nws yuav tsis yog granite.
Kev nqus dej: Tso ib tee dej rau sab nraub qaum ntawm lub pob zeb thiab saib qhov nqus dej. Granite muaj cov qauv ntom thiab nqus dej tsawg. Dej tsis yooj yim nkag mus thiab nthuav qeeb qeeb ntawm nws qhov chaw. Marble muaj peev xwm nqus dej siab, thiab dej yuav nkag mus lossis nthuav sai. Yog tias cov tee dej ploj mus lossis nthuav sai, lawv yuav tsis yog granite.
Lub suab ntaus: Maj mam ntaus lub pob zeb nrog rauj me me lossis cov cuab yeej zoo sib xws. Cov granite zoo muaj cov qauv ntom thiab ua rau lub suab meej thiab zoo siab thaum ntaus. Yog tias muaj cov kab nrib pleb sab hauv lossis cov qauv xoob, lub suab yuav qis. Lub suab ntawm marble raug ntaus tsis tshua meej.
III. Tshawb xyuas qhov zoo ntawm kev ua tiav
Kev Sib Tsoo thiab Kev Ua Kom Zoo: Tuav lub pob zeb rau ntawm lub hnub ci lossis lub teeb fluorescent thiab saib qhov chaw uas muaj kev cuam tshuam. Tom qab qhov chaw ntawm cov granite zoo raug sib tsoo thiab ua kom zoo, txawm hais tias nws cov qauv me me tsis sib xws thaum lub tshuab microscope muaj zog loj, nws yuav tsum ci ntsa iab li daim iav rau lub qhov muag liab qab, nrog rau cov qhov me me thiab tsis sib xws thiab cov kab txaij. Yog tias muaj cov kab txaij pom tseeb thiab tsis tu ncua, nws qhia txog kev ua haujlwm tsis zoo thiab tej zaum yuav yog cov khoom cuav lossis cov khoom tsis zoo.
Seb puas yuav siv tshuaj pleev xim: Qee tus tub luam tsis muaj kev ntseeg yuav siv tshuaj pleev xim rau saum npoo ntawm lub pob zeb kom npog cov qhov tsis zoo ntawm kev ua haujlwm. Kov lub npoo ntawm lub pob zeb nrog koj txhais tes. Yog tias nws zoo li roj, tej zaum nws tau siv tshuaj pleev xim lawm. Koj tuaj yeem siv lub qhov sib tw uas ci los ci saum npoo ntawm lub pob zeb. Qhov roj ntawm lub pob zeb uas muaj tshuaj pleev xim yuav pom tseeb dua.
Plaub. Ua tib zoo mloog lwm yam ntsiab lus
Tshawb xyuas daim ntawv pov thawj thiab qhov chaw: Nug tus tub luam kom tau daim ntawv pov thawj tshuaj xyuas zoo ntawm lub pob zeb thiab xyuas seb puas muaj cov ntaub ntawv xeem xws li cov cim qhia txog radioactive. Nkag siab txog qhov chaw ntawm lub pob zeb, qhov zoo ntawm granite tsim los ntawm cov chaw khawb av loj yog ruaj khov dua.
Kev txiav txim siab txog tus nqi: Yog tias tus nqi qis dua li tus nqi lag luam ib txwm muaj, ceev faj tias nws yog khoom cuav lossis khoom tsis zoo. Tom qab tag nrho, tus nqi ntawm kev khawb thiab ua cov granite zoo muaj, thiab tus nqi qis dhau tsis tsim nyog heev.
