Granite yog ib lub pob zeb nyuaj, uas muaj ntau lub ntsiab: quartz, feldspar, micas, plagioclase. Granite yog ib qho tseem ceeb ntawm lub ntiaj teb ua kaub puab, thaum tsis muaj pov thawj tseeb tias lub pob zeb no muaj nyob rau lwm lub ntiaj teb ntawm lub hnub ci, yog li cov neeg geologist hu cov khoom no ua lub cim ntawm lub ntiaj teb. Granite yog cov pob zeb tuab heev thiab ruaj khov uas yog siv feem ntau hauv kev tsim kho.

Keeb kwm ntawm granite

Muaj ob txoj hauv kev los ua granite. Thaum xub thawj, lub pob zeb no yog tsim los ntawm cov nplaig qhuav, uas ua kom txias ntawm qhov tob hauv lub ntiaj teb ua kaub puab thiab maj mam ua kom muaj zog. Qhov txiaj ntsig yog cov duab pob zeb granite ci, muaj cov nplej ntawm ntau qhov ntau thiab tsawg.

Qhov thib ob txoj kev tsim cov granite yog los ntawm sedimentary, detrital thiab clayey pob zeb, uas tau tsiv los ntawm cov txheej txheem tectonic thiab poob rau hauv cov txheej sib sib zog nqus ntawm lub ntiaj teb av, qhov twg muaj qhov kub siab, muaj zog siab thiab kub roj yaj tag, ua rau lawv thiab ua rau lawv kev koom ua tiav.

Cov txheej txheem no tau tshwm sim ntau lab xyoo dhau los, thaum lub ntiaj teb tau raug lub tsev txheej txheem saum lub roob.

Kev Sau, hom thiab cov yam ntxwv ntawm granite

Granite muaj ib cov qauv crystalline-granular. Nws cov tshuaj lom neeg muaj pes tsawg leeg yog ua raws cov pob zeb txuas ntxiv hauv calcium, hlau, alkalis thiab magnesium. Cov no yog feldspars, quartz, cov xim pob zeb tsaus. Cov poov tshuaj feldspar ntau tshaj nyob rau hauv cov lus muaj pes tsawg leeg, uas muab lub pob zeb muaj qee qhov ntxoov ntxoo, thiab quartz teb rau qhov muaj cov hmoov nplej translucent hauv granite. Tsis tas li, lwm yam minerals, piv txwv li, monazite lossis ilmenite, tuaj yeem suav nrog qhov sib xyaw ntawm cov pob zeb no, tab sis lawv cov ntsiab lus yog tsawg heev, thiab lawv tsis ib txwm nyob. Qhov peculiarities ntawm cov muaj pes tsawg leeg granite txiav txim siab muaj ntau yam: plagigranite yog lub pob zeb nrog lub cim tseem ceeb ntawm plioclase thiab feldspar me me, hom granite no muaj cov xim pinkish; thiab alaskite yog lub pob zeb nrog lub zog ntawm feldspar thiab tsis muaj cov ntaub ntawv tsaus nti xim. Kuj tseem muaj cov tsiaj xws li syenite, teshenite, diorite. Ntau hom granite muaj cov xim sib txawv: muaj cov grey, dub, liab, liab granite.

Lub pob zeb no yog siv tau ruaj khov, yog li nws tau siv hauv kev tsim kho txij li puag thaum ub los. Granite pob zeb tsis txawv txav, nws yuav luag tsis raug mob los ntawm huab cua, nws yog dej, thiab ntau qhov chaw ua haujlwm tsim tau ntau pua xyoo dhau los tau txig txoj kev muaj sia nyob rau niaj hnub no.

Ntawm lawv yog cov pyramids Iyiv nto moo, qee qhov tau tsim siv cov pob zeb granite. Cov vaj tse tau tsim los ntawm lub pob zeb no hauv Ancient Rome thiab Is Nrias teb.

Qhov kev sib kis no kuj yooj yim rau kev ua haujlwm nrog, polishes zoo, yuav siv sij hawm zoo nkauj, nrog nws cov kev pab koj tuaj yeem tsim daim iav iav. Granite tseem tseem siv rau kev tsim khoom ntawm ntsej muag pob zeb, countertops, monuments, khoom zoo nkauj rau sab hauv, tombstones.
