Granite, raws li cov khoom siv dav siv hauv kev tsim kho, kho kom zoo nkauj, ntsuas ntsuas ntsuas thiab lwm yam kev lag luam, nws qhov ceev yog qhov tseem ceeb rau kev ntsuas qhov zoo thiab kev ua haujlwm. Thaum xaiv cov ntaub ntawv granite, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab lus tseem ceeb uas cuam tshuam rau lawv qhov ntom. Cov hauv qab no yuav piav qhia ntxaws ntxaws rau koj.
I. Mineral Composition
Granite feem ntau yog tsim los ntawm cov zaub mov xws li quartz, feldspar thiab mica. Cov qauv siv lead ua, cov ntsiab lus thiab hom ntawm cov ntxhia no muaj feem cuam tshuam rau qhov ntom ntom. Cov qauv siv lead ua ntawm quartz thiab feldspar yog qhov sib txuam, thiab lawv qhov ntom ntom kuj siab. Thaum cov ntsiab lus ntawm ob cov ntxhia hauv granite yog siab, tag nrho qhov ntom ntom kuj tseem yuav nce ntxiv. Piv txwv li, qee yam ntawm granite nplua nuj nyob rau hauv quartz thiab feldspar feem ntau muaj qhov ntom ntom. Ntawm qhov tsis sib xws, cov qauv siv lead ua ntawm mica yog qhov xoob. Yog tias cov ntsiab lus mica hauv granite yog qhov siab, nws yuav ua rau txo qis hauv nws qhov ntom. Tsis tas li ntawd, granite muaj ntau cov zaub mov uas muaj qhov hnyav molecular xws li hlau thiab magnesium feem ntau muaj qhov ceev dua. Granite, uas yog nplua nuj nyob rau hauv silicate minerals, muaj ib tug kuj tsawg ntom.
Ii. Particle loj thiab qauv
Particle loj
Qhov zoo dua cov granite hais yog, qhov nruj dua lawv tau piled, thiab tsawg dua cov voids sab hauv muaj, uas ua rau muaj kev nce hauv qhov loj ntawm ib chav tsev ntim thiab ntau dua. Conversely, rau ntxhib-grained granite, cov hais yog ib qho nyuaj rau kev sib raug zoo packed ua ke thiab muaj ntau voids, uas ua rau ib tug kuj tsawg ntom.
Qib ntawm cov qauv nruj
Granite nrog cov qauv compact muaj cov pob zeb hauv av uas sib xyaw ua ke nrog yuav luag tsis muaj qhov pom tseeb. Cov qauv no yuav pab kom ceev ceev. Txawm li cas los xij, cov txheej txheem xoob ntawm granite, vim yog kev sib xyaw ua ke ntawm cov khoom, muaj qhov chaw loj thiab ib txwm muaj qis dua. Piv txwv li, granite nrog cov qauv ntom tsim los ntawm cov txheej txheem geological tshwj xeeb muaj qhov sib txawv loj heev piv rau nws cov qauv xoob.
Iii. Qib ntawm Crystallization
Thaum lub sij hawm tsim ntawm granite, raws li qhov kub thiab txias hloov, cov pob zeb hauv av yuav maj mam crystallize. Granite nrog rau qib siab ntawm crystallization muaj ntau qhov kev txiav txim siab thiab cog lus siv lead ua, thiab qhov sib txawv ntawm cov muaju yog me dua. Yog li ntawd, nws muaj ib tug ntau dua nyob rau hauv ib chav tsev ntim thiab ib tug kuj ntau dua ceev. Granite nrog ib tug tsawg degree ntawm crystallization muaj ib tug ntau disordered siv lead ua kev npaj thiab loj qhov sib txawv ntawm cov muaju, uas ua rau ib tug kuj tsawg ntom.
Iv. Pores thiab Cracks
Thaum lub sij hawm tsim thiab mining ntawm granite, pores thiab tawg yuav tshwm sim. Qhov muaj nyob ntawm cov voids no txhais tau hais tias tsis muaj cov khoom ntim hauv qhov no, uas yuav txo tau tag nrho cov khoom ntawm granite thiab yog li txo nws qhov ntom. Qhov ntau qhov pores thiab cov kab nrib pleb muaj, qhov loj ntawm lawv qhov loj thiab qhov dav ntawm lawv qhov kev faib tawm, qhov pom tseeb dua qhov kev txo qis ntawm qhov ntom yuav yog. Yog li ntawd, thaum xaiv cov ntaub ntawv granite, saib seb puas muaj cov pores pom tseeb thiab cov kab nrib pleb ntawm nws qhov chaw tuaj yeem siv los ua qhov tseem ceeb rau kev ntsuas nws qhov ntom.
V. Tsim ib puag ncig
Kev sib txawv geological ib puag ncig tuaj yeem ua rau muaj qhov sib txawv ntawm kev faib tawm thiab cov ntsiab lus ntawm cov ntxhia hauv granite, yog li cuam tshuam rau nws qhov ntom. Piv txwv li, granite tsim nyob rau hauv high-temperature thiab high-pressure tej yam kev mob muaj ntau tiav ntxhia crystallization, ib tug ntau compact qauv, thiab ib tug tej zaum yuav ntau dua. Qhov ntom ntawm granite tsim nyob rau hauv ib qho chaw me me yuav txawv. Tsis tas li ntawd, ib puag ncig yam xws li kub, siab thiab noo noo tuaj yeem cuam tshuam rau cov qauv thiab cov ntxhia hauv cov granite, cuam tshuam tsis ncaj rau nws qhov ntom.
Vi. Txheej txheem txheej txheem
Cov txheej txheem siv hauv cov txheej txheem mining, xws li blasting mining, yuav ua rau cov kab nrib pleb hauv cov granite, cuam tshuam rau nws cov qauv kev ncaj ncees thiab tom qab ntawd muaj qee yam cuam tshuam rau nws qhov ntom. Kev sib tsoo, sib tsoo thiab lwm txoj hauv kev thaum lub sijhawm ua haujlwm kuj tseem tuaj yeem hloov pauv lub xeev thiab cov qauv ntawm granite, yog li cuam tshuam rau nws qhov ntom. Thaum lub sij hawm kev thauj mus los thiab kev cia khoom, cov txheej txheem ntim khoom tsis raug lossis qhov chaw khaws cia hnyav yuav ua rau granite raug nyem, sib tsoo lossis eroded, uas tuaj yeem cuam tshuam rau nws qhov ntom.
Hauv kev xaus, thaum xaiv cov ntaub ntawv granite, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog ntau yam uas cuam tshuam rau qhov ntom ntom uas tau hais los saum toj no txhawm rau ntsuas lawv qhov kev ua tau zoo thiab xaiv cov khoom siv granite uas haum tshaj plaws rau cov ntawv thov tshwj xeeb.
