Granite pob zeb cais los ntawm cov xim
Granite, lub ntsiab tseem ceeb ntawm continental crust, yog ib hom magmatic pob zeb tsim los ntawm condensation ntawm magma hauv qab ntawm qhov chaw, teej tug mus rau qhov tob intrusive pob zeb. Nws yog tsim los ntawm cov zaub mov xws li quartz lossis feldspar. Lub etymology ntawm granite yog Latin granum, uas txhais tau hais tias nplej lossis nplej. Vim granite yog pob zeb plutonic, feem ntau nws tuaj yeem tsim cov pob zeb zoo nkauj uas tuaj yeem pom los ntawm qhov muag liab qab, yog li lub npe.
Granite yog lub pob zeb uas muaj cov qauv crystalline tag nrho. High-zoo granite muaj cov nplua thiab zoo li cov nplej, compact qauv, siab quartz ntsiab lus, thiab ci feldspar.
Granite yog tawv, hnav-resistant, siab-resistant, hluav taws-resistant, acid-resistant, alkali-resistant thiab corrosive gas yaig. Feem ntau ntawm lawv tsuas muaj xim me ntsis, thiab qee qhov yog xim tawv, nrog cov qauv me me hloov, muaj zog spellability, thiab ntau yam kev siv.
Granite yog nplua nuj nyob rau hauv cov kev pab thiab ntau yam, thiab tau dav siv nyob rau hauv civil engineering txij thaum ancient sij hawm. Muaj ntau tshaj 100 hom ntawm ntuj granite nyob rau hauv Suav teb, feem ntau yog concentrated nyob rau hauv Fujian, Shandong, Hubei, Sichuan, Guangxi, Shanxi, Henan thiab Inner Mongolia.
Kev ntxhib los mos ntawm granite yog uniform. Txawm hais tias cov xim yog xim xim, nws kuj yog nplua nuj heev. Raws li cov xim, nws tuaj yeem muab faib ua cov xim hauv qab no:
