Granite ndiyo mhando yakapararira yedombo pamusoro pepamusoro.Inoumba huwandu hweiyo continental crust yakanyanya kushanduka maererano nemakemikari ayo uye chiratidzo chakakosha chinosiyanisa Nyika kubva kune mamwe mapuraneti.Iyo inobata zvakavanzika zvekukura kwekondinendi crust, kushanduka kwejasi uye crust, uye ine mineral resources.
Panyaya yegenesis, granite idombo rakadzama rinopinza acidic magmatic, iro rinonyanya kugadzirwa sedombo kana dhizaini.Hazvina kuoma kusiyanisa granite nechitarisiko chayo;Chimiro chayo chakacheneruka, kunyanya ruvara-ruvara rwenyama.Maminerari makuru anoumba granite ndeye quartz, feldspar uye mica, saka kazhinji ruvara uye kupenya kwegranite kuchasiyana zvichienderana nefeldspar, mica uye rima zvicherwa.Mune granite, quartz inokwana 25-30% yehuwandu, ine chitarisiko chegirazi duku rine greasy sheen;potassium feldspar inotora 40-45% yefeldspar uye plagioclase 20%.Chimwe chezvinhu zve mica ndechekuti inogona kukamurwa kuita matete flakes ane tsono padivi pekuvaka.Dzimwe nguva granite inoperekedzwa neparamorphic minerals yakadai seamphibole, pyroxene, tourmaline uye garnet, asi izvi hazvina kujairika kana kuti hazvionekwi nyore.
Zvakanakira zvegranite zvakatanhamara, ine homogeneous, yakaoma, kunyura kwemvura kushoma, simba rekumanikidza redombo rinogona kusvika 117.7 kusvika 196.1MPa, saka inowanzoonekwa sehwaro hwakanaka hwezvivakwa, senge Three Gorges, Xinfengjiang, Longyangxia, Tenseitan nemamwe madhamu emagetsi akavakirwa pagranite.Granite zvakare ibwe rekuvaka rakanakisa, rine kuoma kwakanaka, uye rine simba rakanyanya kudzvanya, diki porosity, kunyura kwemvura yakaderera, kukurumidza kupisa conductivity, kunaka kupfeka kusagadzikana, kusimba kwakanyanya, chando kuramba, acid resistance, corrosion resistance, hazvisi nyore kutarisana nemamiriro ekunze. , saka inowanzoshandiswa kuvaka mabhiriji piers, matanho, migwagwa, asiwo kune dzimba dzemasonry, fenzi uye zvichingodaro.Granite haina kusimba chete uye inoshanda, asiwo ine nzvimbo yakatsetseka ine makona akashambidzika, saka inowanzoshandiswa mukushongedza kwemukati uye inoonekwa seyepamusoro-giredhi dombo rekushongedza.
Granite haisi yemhando yedombo rimwe chete, asi ine zvakawanda zvakasiyana, imwe neimwe inoratidzira zvakasiyana-siyana zvichienderana nezvinhu zvakasanganiswa.Kana granite yakasanganiswa ne orthoclase, inowanzoita pink.Mamwe magranite ane grey kana, kana achinja-chinja, akasvibira.
