Kutheni ilitye legranite lomelele kwaye lomelele?
IGranitelelinye lawona matye omeleleyo etyeni. Ayinzima nje kuphela, kodwa ayinyibilikiswa lula ngamanzi. Ayinakuchaphazeleka kukhukuliseko nge-asidi kunye ne-alkali. Inokumelana ngaphezu kwe-2000 kg yoxinzelelo kwi-square centimeter nganye. Imozulu ayinayo impembelelo ecacileyo kuyo kangangamashumi eminyaka.

Imbonakalo yegranite isemhle kakhulu, ihlala ibonakalamnyama, mhlophe, ngwevu, lubhelu, umbala weentyatyambo, i-rose kunye nokunye umbala ongekho nzulu, udibanise indawo emnyama, enhle kunye nesisa. Iinzuzo ezingentla, ziba yinto ekhethiweyo ephezulu kwilitye lokwakha. Ilitye lentliziyo lesikhumbuzo samagorha abantu eBeijing's tiananmen square lenziwe kwiqhekeza legranite eliye lathunyelwa lisuka eLaoshan, kwiphondo laseShandong.

Kutheni igranite inezi mpawu?
Makhe sihlolisise izithako zayo kuqala. Kwiincinci zamaminerali ezenza i-granite, ngaphezu kwe-90% yizimbiwa ezimbini, i-feldspar kunye ne-quartz, nazo ziyi-feldspar kakhulu. I-Feldspar ihlala imhlophe, ingwevu, ibomvu, kwaye i-quartz ayinambala okanye ingwevu, ezenza ii-hues ezisisiseko zegranite. I-Feldspar kunye ne-quartz ziiminerali ezinzima kwaye kunzima ukuhamba ngeemela zetsimbi. Ngokuphathelele amabala amnyama kwigranite, ikakhulu i-mica emnyama kunye nezinye iiminerali. Nangona i-black mica ithambile, ayinamandla ekuchaseni uxinzelelo, kwaye iinqununu zayo kwi-granite zincinci kakhulu, zihlala zingaphantsi kwe-10%. Le yimeko yezinto eziqinileyo zegranite.
Esinye isizathu sokuba i-granite yomelele kukuba iinkozo zayo zeminerali zibotshelelwe ngokuqinileyo omnye komnye, kwaye iipores zihlala ziba ngaphantsi kwe-1% yomthamo opheleleyo wamatye. Oku kunika i-granite amandla okumelana noxinzelelo olunamandla kwaye ayingenwa lula ngamanzi.

I-Granite nangona yomelele ngokukodwa, kodwa kwixesha elide lokukhanya kwelanga, umoya, amanzi kunye ne-biology, kuya kubakho usuku "lokubola", ngaba unokukholelwa? Uninzi lwentlabathi esemlanjeni ziinkozo ze-quartz eziye zashiywa emva kokutshatyalaliswa, kwaye udongwe olusasazwa ngokubanzi luyimveliso yemozulu ye-granite. Kodwa iya kuba yinde, ixesha elide, ngoko ngokwexesha lomntu, igranite yomelele kakhulu.
