Kungani itshe le-granite liqinile futhi lihlala isikhathi eside kangaka?
I-Graniteingenye yamadwala aqine kakhulu edwaleni. Ayiqinile nje kuphela, kodwa ayincibiliki kalula ngamanzi. Ayikwazi ukuguguleka ngenxa ye-asidi ne-alkali. Ingamelana nokucindezela okungaphezu kuka-2000 kg ngesentimitha lesikwele. Ukuwa kwezulu akunawo umphumela ocacile kulo amashumi eminyaka.

Ukubukeka kwe-granite kusekuhle impela, kuvame ukuvelamnyama, okumhlophe, impunga, ophuzi, umbala wezimbali, i-rose nokunye okunombala ongajulile, kufaka phakathi ibala elimnyama, lihle futhi linomusa. Izinzuzo ezingenhla, liba yisinqumo esiphezulu etsheni lokwakha. Itshe lenhliziyo lesikhumbuzo samaqhawe abantu esigcawini saseBeijing iTiananmen lenziwe ngengcezu yegranite ethunyelwe ivela eLaoshan, esifundazweni saseShandong.

Kungani i-granite inalezi zici?
Ake sihlole izithako zayo kuqala. Ezinhlayiyeni zamaminerali ezakha i-granite, ezingaphezu kuka-90% yizona zimbiwa ezimbili, i-feldspar ne-quartz, okuyizona ezivame kakhulu i-feldspar. I-Feldspar ivame ukuba mhlophe, mpunga, bomvu, kanti i-quartz ayinambala noma impunga, ezakha imibala eyisisekelo ye-granite. I-Feldspar ne-quartz ziyizimbiwa eziqinile futhi kunzima ukuzihambisa ngemimese yensimbi. Ngokuphathelene namabala amnyama ku-granite, ikakhulukazi i-mica emnyama kanye nezinye izimbiwa. Nakuba i-mica emnyama ithambile, ayibuthakathaka ekumelaneni nengcindezi, futhi izingxenye zayo ku-granite zincane kakhulu, ngokuvamile zingaphansi kuka-10%. Lesi yisimo sezinto eziqinile kakhulu ze-granite.
Esinye isizathu sokuba i-granite ibe namandla ukuthi izinhlayiya zayo zamaminerali ziboshwe ngokuqinile komunye nomunye, nokuthi izimbobo zivame ukuba ngaphansi kuka-1% womthamo ophelele wedwala. Lokhu kunikeza i-granite ikhono lokumelana nokucindezela okukhulu futhi amanzi awangeni kalula.

Nokho, i-granite inamandla kakhulu, kodwa esikhathini eside sokukhanya kwelanga, umoya, amanzi kanye ne-biology, kuzoba nosuku "lokubola", ungakukholwa? Iningi lesihlabathi emfuleni yizinhlayiya ze-quartz ezishiywe ngemuva kokubhujiswa kwayo, futhi ubumba olusakazeke kabanzi nalo luwumkhiqizo wokuguquka kwe-granite. Kodwa kuzoba isikhathi eside, ngakho-ke ngokwesikhathi somuntu, i-granite iqinile impela.
