Igranite lolona hlobo luxhaphake kakhulu lwamatye kumphezulu.Yenza isambuku se-continental crust evele kakhulu ngokwemichiza yayo kwaye siphawu olubalulekileyo olwahlula uMhlaba kwezinye iiplanethi.Ibambe iimfihlo zokukhula kwe-continental crust, ukuvela kwengubo kunye ne-crust, kunye nemithombo yezimbiwa.
Ngokubhekiselele kwi-genesis, i-granite lilitye le-acidic magmatic elingena ngokunzulu, eliveliswa kakhulu njengesiseko samatye okanye ubunzima.Akunzima ukwahlula igraniti ngokubonakala kwayo;uphawu lwayo olwahlukileyo luluthuthu, umbala wayo obomvu wenyama.Iiminerali eziphambili ezenza i-granite yi-quartz, i-feldspar kunye ne-mica, ngoko ke kaninzi umbala kunye ne-luster ye-granite iya kuhluka ngokuxhomekeke kwi-feldspar, i-mica kunye neeminerali ezimnyama.Kwi-granite, i-quartz yenza i-25-30% yetotali, inokubonakala kweglasi encinci ene-greasy sheen;I-potassium feldspar i-akhawunti ye-40-45% ye-feldspar kunye ne-plagioclase i-20%.Enye yeepropathi zemica kukuba inokwahlulwa ibe ziiflakes ezincinci kunye nenaliti ecaleni kwe-deconstruction.Ngamanye amaxesha i-granite ihamba kunye neeminerali ze-paramorphic ezifana ne-amphibole, i-pyroxene, i-tourmaline kunye ne-garnet, kodwa oku akuqhelekanga okanye akubonakali lula.
Izinto eziluncedo zegranite zibalasele, i-homogeneous, ilukhuni, incinci ukufunxa kwamanzi, amandla acinezelayo elitye lelitye anokufikelela kwi-117.7 ukuya kwi-196.1MPa, ngoko ihlala ithathwa njengesiseko esihle sezakhiwo, njengemiwonyo emithathu, iXinfengjiang, I-Longyangxia, i-Tenseitan kunye namanye amadama ombane akhiwe phezu kwegranite.I-Granite ikwalelona litye lokwakha eligqwesileyo, linobulukhuni obuhle, kwaye linamandla acinezelayo aphezulu, i-porosity encinci, ukufunxwa kwamanzi aphantsi, i-thermal conductivity ekhawulezayo, ukumelana nokunxiba kakuhle, ukuhlala ixesha elide, ukumelana neqabaka, ukumelana ne-asidi, ukuxhathisa umhlwa, akukho lula ukumelana nemozulu. , ngoko isoloko isetyenziselwa ukwakha i-bridge piers, amanyathelo, iindlela, kodwa kunye nezindlu zamatye, iingcingo kunye nokunye.I-Granite ayinamandla kwaye iyasebenza kuphela, kodwa inomgangatho ogudileyo onama-engile acocekileyo, ngoko isoloko isetyenziselwa ukuhlobisa kwangaphakathi kwaye ithathwa njengelitye eliphezulu lokuhombisa.
I-Granite ayilohlobo olunye lwelitye, kodwa ineentlobo ezininzi, nganye kuzo ibonisa iimpawu ezahlukeneyo ngokuxhomekeke kwizinto ezixutywe kuzo.Xa i-granite ixutywe ne-orthoclase, ngokuqhelekileyo ibonakala i-pink.Ezinye iigraniti zingwevu okanye, xa zilungiswa, zibe luhlaza bumnyama.
