Vim li cas pob zeb granite thiaj li muaj zog thiab ruaj khov?
Pob zeb graniteyog ib qho ntawm cov pob zeb muaj zog tshaj plaws hauv cov pob zeb. Nws tsis yog tsuas yog tawv xwb, tab sis tsis yooj yim yaj los ntawm dej. Nws tsis yooj yim rau kev yaig los ntawm kua qaub thiab alkali. Nws tuaj yeem tiv taus ntau dua 2000 kg ntawm lub siab ib square centimeter. Weathering tsis muaj qhov cuam tshuam rau nws rau ntau xyoo caum.

Cov tsos ntawm granite tseem zoo nkauj heev, feem ntau tshwm simdub, dawb, xim grey, daj, xim paj, paj liab thiab lwm yam xim tsis tob, sib tshuam qhov chaw dub, zoo nkauj thiab dav. Qhov zoo saum toj no, nws dhau los ua qhov kev xaiv saum toj kawg nkaus hauv pob zeb tsim kho. Lub pob zeb plawv ntawm lub cim rau cov neeg ua siab loj hauv Beijing's tiananmen square yog ua los ntawm ib daim granite uas tau xa los ntawm laoshan, xeev shandong.

Vim li cas granite muaj cov yam ntxwv no?
Ua ntej, cia peb tshuaj xyuas nws cov khoom xyaw. Ntawm cov khoom me me uas ua rau granite, ntau dua 90% yog ob hom minerals, feldspar thiab quartz, uas kuj yog feldspar feem ntau. Feldspar feem ntau yog dawb, grey, liab, thiab quartz yog tsis muaj xim lossis grey, uas ua rau cov xim yooj yim ntawm granite. Feldspar thiab quartz yog cov minerals tawv thiab nyuaj rau txav nrog riam hlau. Raws li rau cov chaw tsaus ntuj hauv granite, feem ntau yog dub mica thiab lwm yam minerals. Txawm hais tias dub mica yog mos, nws tsis tsis muaj zog hauv kev tiv thaiv siab, thiab nws cov khoom hauv granite yog me me heev, feem ntau tsawg dua 10%. Qhov no yog cov khoom siv khov kho ntawm granite.
Lwm qhov laj thawj uas ua rau cov pob zeb granite muaj zog yog vim nws cov pob zeb minerals tau sib txuas ua ke zoo, thiab cov qhov hws feem ntau tsuas yog tsawg dua 1% ntawm tag nrho cov pob zeb. Qhov no ua rau cov pob zeb granite muaj peev xwm tiv taus qhov siab thiab tsis yooj yim nkag mus rau hauv dej.

Txawm hais tias granite muaj zog heev, tab sis nyob rau lub sijhawm ntev ntawm lub hnub ci, huab cua, dej thiab biology, yuav muaj ib hnub "roj", koj puas ntseeg nws? Ntau cov xuab zeb hauv tus dej yog cov pob zeb quartz uas tau tso tseg tom qab nws raug rhuav tshem, thiab cov av nplaum uas tau faib dav dav kuj yog cov khoom ntawm kev puas tsuaj ntawm granite. Tab sis nws yuav siv sijhawm ntev, yog li ntawd hauv tib neeg lub sijhawm, granite yog khov kho heev.
