Kutheni ilitye legranite liqinile kwaye lihlala ixesha elide kangaka?
Igranitelelinye lamatye anamandla kakhulu kweli litye. Aliqinanga nje kuphela, kodwa alinyibiliki lula ngamanzi. Alinakukhukuliseka ngenxa ye-asidi kunye ne-alkali. Linokumelana noxinzelelo olungaphezulu kwama-2000 kg ngesentimitha yesikwere. Imozulu ayinayo impembelelo icacileyo kulo kangangeminyaka emininzi.

Imbonakalo yegranite isentle kakhulu, ihlala ivelemnyama, mhlophe, ngwevu, lubhelu, umbala weentyatyambo, irozi njalo njalo, umbala ongaphantsi, udibanisa ibala elimnyama, lihle kwaye linobubele. Iingenelo ezingentla, liba lolona khetho luphezulu kwilitye lokwakha. Ilitye lentliziyo lesikhumbuzo samaqhawe abantu kwisikwere saseTiananmen eBeijing lenziwe ngesiqwenga segranite esithunyelwe sisuka eLaoshan, kwiphondo laseShandong.

Kutheni i-granite inezi mpawu?
Masiqale sihlolisise izithako zayo. Kwiziqwenga zeeminerali ezenza igranite, ngaphezulu kwama-90% ziiminerali ezimbini, i-feldspar kunye ne-quartz, ezikwazezona zininzi ze-feldspar. I-Feldspar idla ngokuba mhlophe, ngwevu, bomvu, kwaye i-quartz ayinambala okanye ngwevu, ezenza imibala esisiseko yegranite. I-Feldspar kunye ne-quartz ziiminerali eziqinileyo kwaye kunzima ukuzihambisa ngeemela zentsimbi. Ngokuphathelele amabala amnyama kwigranite, ikakhulu i-mica emnyama kunye nezinye iiminerali. Nangona i-mica emnyama ithambile, ayibuthathaka ekumelaneni noxinzelelo, kwaye izinto zayo kwigranite zincinci kakhulu, zihlala zingaphantsi kwe-10%. Le yimeko eqinileyo yezinto zegranite.
Esinye isizathu sokuba igranite ibe namandla kukuba iinkozo zayo zeminerali zibotshelelwe ngokuqinileyo, kwaye iimbobo zihlala zingaphantsi kwe-1% yomthamo uwonke welitye. Oku kunika igranite amandla okumelana noxinzelelo olunamandla kwaye ayingeni lula ngamanzi.

Nangona igranite inamandla kakhulu, kodwa kwixesha elide lokukhanya kwelanga, umoya, amanzi kunye nebhayoloji, kuya kubakho usuku "lokubola", ungakholelwa? Uninzi lwesanti emlanjeni ziinkozo ze-quartz ezishiywe ngasemva emva kokuba zitshatyalalisiwe, kwaye udongwe olusasazeke kakhulu lukwangumphumo wokuguguleka kwegranite. Kodwa kuza kuthatha ixesha elide, ngoko ke ngokwexesha lomntu, igranite iqinile kakhulu.
