Dab tsi khoom muab granite nws cov xim zoo nkauj?

Thaum koj xauj ntau yam ntawm granite thiab lwm yam pob zeb ntuj ntawm Tingida Pob zeb, koj yuav pom zaj sawv ntawm cov xim thiab cov qauv ntawm txhua qhov slab. Txhua qhov chaw, streak, xim thiab siv lead ua koj pom hauv granite yog cov ntxhia sib txawv, txhua tus muaj nws tus kheej qhov muag thiab lub cev. Txawm hais tias koj tab tom yuav khoom tshiab granite lossis xav paub ntau ntxiv txog koj qhov chaw pob zeb uas twb muaj lawm, peb yuav pab koj nkag siab qee yam ntawm cov zaub mov uas koj yuav ntsib.

Minerals yog cov khoom tseem ceeb ntawm granite. Qhov tseeb, txhua lub pob zeb ntuj yog tsim los ntawm ntau hom minerals, los ntawm cov pob zeb loj loj mus rau cov nplej zoo uas tuaj yeem pom los ntawm lub iav loj. Granite feem ntau yog tsim los ntawm cov zaub mov feldspar thiab quartz, nrog rau amphibole, mica, thiab garnet.

Feldspar

Feldspar tsis yog tsuas yog cov khoom tseem ceeb ntawm granite, nws tseem yog lub ntsiab ntawm lub ntiaj teb crust. Nws yog cov ntxhia ntau tshaj plaws hauv ntiaj teb thiab feem ntau siv los ua keeb kwm yav dhau los lossis undertone rau granite. Nws tuaj yeem nyob ntawm txhua qhov dub mus rau dawb mus rau txhua yam zoo nkauj nyob nruab nrab, uas txhais tau hais tias xim yuav tsis yog qhov zoo tshaj plaws rau kev txheeb xyuas feldspar.

Feldspar yog cov khoom siv tawv thiab ruaj khov, feem ntau ntsuas ib ncig ntawm 6 ntawm Mohs hardness tester. Feem ntau, nws yuav tsis khawb, khawb lossis smudge.

Feem ntau koj tuaj yeem txheeb xyuas feldspar hauv granite los ntawm nws cov duab thiab kev ntxhib los mos, raws li nws feem ntau tuaj rau hauv daim ntawv loj "chunks." Cov chunks no tuaj yeem sib txawv ntawm qhov me me mus rau qhov loj, thiab feem ntau qhia cov qauv hloov maj mam ntawm kab txaij lossis zawj ntawm kev tshuaj xyuas ze dua. Nyob rau hauv daim ntawv magma ntawm granite, feldspar fragments feem ntau tsis liquefy, tab sis khaws lawv cov duab thiab cov qauv, ntab hauv cov dej sib tov zoo li dej khov hauv Ntshav Mary.

Quartz

Tsis txhob tsis meej pem nrog cov pob zeb dag ntawm tib lub npe, quartz yog qhov thib ob ntau tshaj plaws hauv ntiaj teb. Quartz yog nrov heev sab nraum countertops rau nws cov khoom ruaj khov thiab muaj peev xwm tuav thiab ua lub zog. Quartz feem ntau yog pob tshab lossis translucent, nrog qee qhov xim tseem ceeb ntawm cov pob zeb sib txawv, qee zaum cuam tshuam los ntawm cov ntxhia nyob ib puag ncig. Quartz tuaj yeem muaj xim xws li dub, grey, liab, dawb thiab txawm liab.

Quartz nyuaj dua li feldspar, nrog Mohs hardness ntawm 7, ua rau nws tsis tshua muaj siab thiab kav ntev.

Quartz tuaj yeem ua tau nyob rau hauv txhua yam, raws li nws feem ntau nyob hauv interstices ntawm lwm yam minerals thaum nws txias los ntawm nws daim ntawv magma. Nws yog cov ntxhia kawg kom txias thiab tawv los ntawm nws lub xeev molten, yog li cov kab nrib pleb lossis qhov uas tshuav los ntawm cov khoom feldspar tau ntim nrog quartz. Nyob rau hauv feem ntau granites, koj tuaj yeem yooj yim txheeb xyuas quartz los ntawm nws kos npe crystalline tsos.

Amphibole

Amphibole tseem hu ua amphibole. Feem ntau yooj yim los txheeb xyuas vim nws qhov sib txawv rau ib puag ncig quartz lossis feldspar, amphibole qee zaum pom hauv cov granite sib zog hauv cov streaks lossis cov qauv sib txawv.

Amphibole nyuaj li feldspar, nrog rau Mohs nplai ntawm 5-6. Nws muaj cov khoom zoo sib xws rau iav.

Amphibole yog dawb huv dub, feem ntau nyob rau hauv elongated crystals. Cov Crystals feem ntau yog cov duab plaub los yog lub ntsej muag, tab sis qee zaum tshwm sim hauv pawg me.

Mica

Vim lawv qhov zoo sib xws, mica qee zaum tsis meej pem nrog feldspar. Nws yog ib qho uas pom mica nyob rau hauv ib daim ntawm granite, feem ntau tsim ib qho kev ntxhib los mos los yog qauv nyob rau hauv lub pob zeb.Cov xim ntawm mica tuaj yeem yog xim dub, xim hlau lossis nyiaj. Nws muaj nyob rau hauv qhov tsaus ntuj thiab lub teeb-xim granite thiab yog lub hauv paus ntawm cov qauv "glitter" uas yog nrov hauv ntau lub pob zeb ntuj.

Koj yuav tsis pom ntau qhov tso nyiaj ntau ntawm mica nyob qhov twg hauv cov qib nyob hauv granite, vim nws yog cov ntxhia pob zeb mos thiab pliable. Nws yog feem ntau embedded nyob rau hauv feldspar thiab tshwm li dub, nqaim kab ntawm polished granite nto.

Mica feem ntau pom nyob rau hauv daim ntawv ntawm nyias, wavy flakes los yog sparkling metallic deposits. Thaum tsis ntseeg, qhov zoo li ntawm mica yog pom tau yooj yim tshaj plaws ntawm ntug tsis tiav ntawm granite slab, qhov twg koj tuaj yeem pom cov ntawv-nyias flakes kom meej meej.

Garnet

Ib qho ntxhia uas koj tuaj yeem paub los ntawm koj pog cov hniav nyiaj hniav kub, garnet muaj ntau dua li koj xav. Txawm hais tias nws tau suav hais tias yog pob zeb muaj txiaj ntsig, nws muaj nyob hauv ntau qhov nrov granites thiab tuaj yeem ntxiv cov xim zoo nkauj rau koj cov txee.

Garnet yog cov ntxhia tshwj xeeb thiab ruaj khov nrog Mohs hardness txog 7.

Garnet yog pom tseeb yooj yim los txheeb xyuas los ntawm cov xim, raws li nws tsuas yog txawv los ntawm ci liab mus rau tob liab. Garnets tuaj yeem tshwm sim raws li huab zoo li pawg, me me puag ncig tso nyiaj, lossis cov specks tawg.

Txawm hais tias tsis muaj ob daim ntawm granite zoo ib yam, kev paub txog tsib cov zaub mov no yuav ua rau nws yooj yim dua kom nqaim koj xaiv ntawm qhov zoo, xim, thiab style ntawm ntuj pob zeb. Txawm hais tias nws yog los pab koj kom muaj kev paub zoo dua hauv kev yuav khoom pob zeb, lossis kawm qee qhov kev paub tshiab, kom koj tuaj yeem ua rau koj nyiam koj cov phooj ywg hauv kev sib txuas lus nrog koj cov phooj ywg, peb txhua tus cia siab tias yuav pab tau koj!
