Ntawm qhov sib txawv ntawm marble thiab granite

Txoj hauv kev kom paub qhov txawv ntawm marble los ntawm granite yog pom lawv cov qauv. Cov qauv ntawmmarbleyog nplua nuj, kab qauv yog du, thiab xim hloov yog nplua nuj. Covgranitecov qauv yog speckled, tsis muaj cov qauv pom tseeb, thiab cov xim feem ntau yog dawb thiab grey, thiab yog ib qho tseem ceeb.

CovGranite
Granite belongs rau igneous pob zeb, uas yog tsim los ntawm eruption ntawm underground magma thiab invasion ntawm txias crystallization thiab metamorphic pob zeb ntawm granite. Nrog pom cov qauv siv lead ua thiab kev ntxhib los mos. Nws yog tsim los ntawm feldspar (feem ntau yog poov tshuaj feldspar thiab oligoclase) thiab quartz, mingled nrog ib tug me me ntawm mica (dub mica los yog dawb mica) thiab kab kawm minerals, xws li: zircon, apatite, magnetite, ilmenite, sphene thiab hais txog. Cov ntsiab lus tseem ceeb ntawm granite yog silica, nws cov ntsiab lus yog li 65% - 85%. Cov khoom siv tshuaj lom neeg ntawm granite tsis muaj zog thiab acidic. Feem ntau, cov granite yog me ntsis dawb los yog grey, thiab vim muaj cov muaju tsaus, cov tsos yog speckled, thiab ntxiv cov poov tshuaj feldspar ua rau nws liab los yog fleshy. Granite tsim los ntawm magmatic maj mam txias crystallization, faus tob hauv qab ntawm lub ntiaj teb, thaum tsis tshua muaj qhov txias txias, nws yuav tsim ib qho kev ntxhib los mos ntawm granite, hu ua crystalline granite. Granite thiab lwm cov pob zeb crystalline tsim lub hauv paus ntawm cov phaj continental, uas kuj yog cov pob zeb ntau tshaj plaws uas raug rau lub ntiaj teb saum npoo.

Txawm hais tias granite tau txiav txim siab los ntawm cov khoom siv yaj lossis cov pob zeb igneous magma, tab sis muaj ntau cov pov thawj qhia tias kev tsim ntawm qee cov granite yog cov khoom ntawm lub zos deformation los yog yav dhau los pob zeb, lawv tsis yog los ntawm cov kua los yog yaj txheej txheem thiab rearrange thiab recrystallization. Qhov hnyav ntawm granite yog nruab nrab ntawm 2.63 thiab 2.75, thiab nws lub zog compressive yog 1,050 ~ 14,000 kg / sq cm (15,000 ~ 20, 000 phaus ib square inch). Vim tias granite muaj zog dua li cov xuab zeb, limestone thiab marble, nws nyuaj rau extract. Vim tias cov xwm txheej tshwj xeeb thiab cov qauv ruaj khov ntawm granite, nws muaj cov yam ntxwv hauv qab no:
