I-Granite, njengezinto ezisetshenziswa kabanzi ekwakheni, ekuhlobiseni, ezisekelweni zezinsimbi ezinembile nakwezinye izinkambu, ubuningi bayo buyisibonakaliso esibalulekile sokulinganisa ikhwalithi nokusebenza. Lapho ukhetha izinto ze-granite, kubalulekile ukuqonda izici ezibalulekile ezithinta ubuningi bazo. Okulandelayo kuzokuchazela kabanzi ngakho.
I. Ukwakheka Kwamaminerali
I-granite yakhiwe kakhulu ngamaminerali afana ne-quartz, i-feldspar kanye ne-mica. Isakhiwo sekristalu, okuqukethwe kanye nohlobo lwala maminerali konke kunomthelela omkhulu ekuxineni. Izakhiwo zekristalu ze-quartz kanye ne-feldspar zincane kakhulu, futhi ubuningi bazo buphakeme kakhulu. Uma okuqukethwe kwala maminerali amabili ku-granite kuphakeme, ubuningi buzokhula ngokufanele. Isibonelo, ezinye izinhlobo ze-granite ezicebile ku-quartz kanye ne-feldspar zivame ukuba nobukhulu obuphezulu kakhulu. Ngokuphambene nalokho, isakhiwo sekristalu se-mica sikhululekile kakhulu. Uma okuqukethwe kwe-mica ku-granite kuphakeme kakhulu, kuzoholela ekwehleni kobuningi bayo. Ngaphezu kwalokho, i-granite equkethe amaminerali amaningi anesisindo sama-molecule aphezulu njengensimbi kanye ne-magnesium ivame ukuba nobukhulu obuphezulu. I-granite, ecebile ngamaminerali e-silicate, inobukhulu obuphansi kakhulu.
Ii. Usayizi Wezinhlayiyana Nesakhiwo
Usayizi wezinhlayiya
Uma izinhlayiya zegranite zincane, ziqina kakhulu, futhi kulapho izikhala zangaphakathi zincane khona, okuholela ekwandeni kwesisindo ngeyunithi ngayinye kanye nobuningi obuphezulu. Ngokuphambene nalokho, ngegranite enamabala amakhulu, izinhlayiya kunzima ukuhlanganiswa ndawonye futhi kunezikhala eziningi, okuholela ekuxineni okuphansi kakhulu.
Izinga lokuqina kwesakhiwo
I-Granite enesakhiwo esincane inezinhlayiya zamaminerali ezihlanganiswe eduze cishe nezikhala ezingabonakali. Lesi sakhiwo sisiza ukwandisa ubuningi. Kodwa-ke, i-granite ehlelekile ngokukhululekile, ngenxa yokuhlanganiswa okukhululekile phakathi kwezinhlayiya, inesikhala esikhulu futhi ngokwemvelo inobukhulu obuphansi. Isibonelo, i-granite enesakhiwo esiqinile esakhiwe ngezinqubo ezikhethekile ze-geological inobukhulu obuhlukile kakhulu uma kuqhathaniswa nomlingani wayo ohlelekile ngokukhululekile.
Iii. Izinga Lokwakheka Kwekristalu
Ngesikhathi sokwakheka kwe-granite, njengoba izinga lokushisa kanye nokushintsha kwengcindezi kushintsha, amakristalu amaminerali azocwebezela kancane kancane. I-granite enezinga eliphezulu lokucwebezela inokuhlelwa kwekristalu okuhlelekile nokuncane, kanti izikhala phakathi kwamakristalu zincane. Ngakho-ke, inobunzima obukhulu ngeyunithi ngayinye kanye nobuningi obuphakeme. I-granite enezinga eliphansi lokucwebezela inokuhlelwa kwekristalu okuphazamisekile kanye nezikhala ezinkulu phakathi kwamakristalu, okuholela ekubuneni okuphansi.
Iv. Imigodi kanye nemifantu
Ngesikhathi sokwakheka nokumbiwa kwe-granite, kungase kube nezimbobo nezimfa. Ukuba khona kwalezi zimfa kusho ukuthi akukho ukugcwaliswa kwezinto eziqinile kule ngxenye, okuzonciphisa isisindo se-granite futhi ngaleyo ndlela kwehlise ubuningi bayo. Uma izimbobo nezimfa ziba ziningi, ubukhulu bazo bukhulu futhi ukusatshalaliswa kwazo kubanzi, kulapho umphumela wokunciphisa ubuningi uzoba sobala khona. Ngakho-ke, lapho ukhetha izinto ze-granite, ukubheka ukuthi zikhona yini izimbobo nezimfa ezisobala ebusweni bayo kungasetshenziswa njengesici sokubhekisela sokuhlola ubuningi bayo.
V. Ukwakha Indawo Ezungezile
Izimo ezahlukene zemvelo zingaholela ekwehlukeni kokusatshalaliswa kanye nokuqukethwe kwamaminerali ku-granite, ngaleyo ndlela kuthinte ubuningi bawo. Isibonelo, i-granite eyakhiwe ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu ine-crystallization ephelele yamaminerali, isakhiwo esincane kakhulu, kanye nobuningi obungaba phezulu. Ubuningi be-granite obakhiwe endaweni emnene bungahluka. Ngaphezu kwalokho, izici zemvelo ezifana nokushisa, ukucindezela kanye nomswakama nazo zingathinta isakhiwo kanye nokwakheka kwamaminerali kwe-granite, zithonye ngokungaqondile ubuningi bayo.
Izindlela Zokucubungula
Izindlela ezisetshenziswa enkambisweni yokumba, njengokumba ngokuqhumisa, zingase zibangele imifantu emincane ngaphakathi kwe-granite, zithinte ubuqotho besakhiwo sayo futhi kamuva zibe nomthelela othile ekuminyaneni kwayo. Ukuchoboza, ukugaya nezinye izindlela ngesikhathi sokucubungula kungashintsha nesimo sezinhlayiya kanye nesakhiwo se-granite, ngaleyo ndlela kuthinte ukuminyana kwayo. Ngesikhathi sokuthuthwa nokugcinwa kwayo, izindlela zokupakisha ezingafanele noma izindawo zokugcina ezinzima zingabangela ukuthi i-granite icindezelwe, ishayisane noma iguguleke, okungase futhi kuthinte ukuminyana kwayo.
Ekuphetheni, lapho ukhetha izinto ze-granite, kubalulekile ukucabangela ngokuphelele izici ezahlukahlukene ezithinta ubuningi okukhulunywe ngabo ngenhla ukuze kuhlolwe ngokunembile ukusebenza kwazo bese kukhethwa izinto ze-granite ezifanele kakhulu ezimweni ezithile zokusetshenziswa.
