Kana zvasvika kune zvikamu zvegranite zvakanyatsonaka, munhu angashamisika kana zvikamu izvi zvichigona kuita ngura. Inyaya ine musoro, sezvo ngura inogona kukanganisa kunaka uye kururama kwezvikamu zvakanyatsonaka, uye pakupedzisira inogona kukonzera kutadza kushanda kwazvo.
Zvisinei, mashoko akanaka ndeekuti zvikamu zvegranite zvakanyatsonaka hazvikuvadzi ngura zvachose. Izvi zvinodaro nekuti granite ichinhu chakasimba zvikuru uye chinogara kwenguva refu chinodzivirira ngura zvakanyanya, kusanganisira ngura.
Granite imhando yedombo reigneous rinoumbwa zvakanyanya nequartz, feldspar, uye mica. Rinoumbwa nekutonhorera uye kuoma kwe magma kana lava, uye rinozivikanwa nekuoma kwayo kwakanyanya uye kugara kwenguva refu. Granite inodzivirirawo zvakanyanya kukweshwa, zvichiita kuti ive chinhu chakanakira zvikamu zvakanyatsonaka zvinoda kunyatsorongeka uye kugara kwenguva refu.
Chikonzero chinoita kuti granite isaite ngura ndechekuti haina iron kana iron oxide, izvo zvinonyanya kukonzera ngura. Ngura imhando yengura inoitika kana iron kana simbi yasangana neokisijeni nehunyoro, izvo zvinotungamira pakuumbwa kweiron oxide. Nekufamba kwenguva, iyi iron oxide inogona kukonzera ngura kupararira, zvichikonzera kukuvara kwechimiro kune chikamu chakakanganiswa.
Nekuti zvikamu zvegranite zvakanyatsonaka hazvina simbi kana simbi, hazviwanzoita ngura. Izvi zvinoita kuti zvive sarudzo yakanaka yekushandisa mumhando dzakasiyana-siyana dzemashandisirwo, kusanganisira michina yekuyera, maturusi emuchina, uye majigi ekubatanidza.
Pamusoro pekusaora, zvikamu zvegranite zvine hungwaru zvinopawo zvimwe zvakanakira. Chekutanga, zvinogara zvakagadzikana uye hazvikure kana kudzikira kana tembiricha kana hunyoro zvichichinja. Izvi zvinoreva kuti zvinogona kuchengetedza kururama uye kururama kwazvo nekufamba kwenguva, kunyangwe mumamiriro ezvinhu akasiyana-siyana.
Zvikamu zvegranite zvakanyatsogadzirwa zvinodzivirirawo kubvaruka, zvichiita kuti zvive sarudzo inodhura kwenguva refu. Hazvidi kugadziriswa zvakanyanya, uye zvinogona kutsungirira kushandiswa zvakanyanya pasina kuratidza zviratidzo zvekusakara kana kuora.
Kazhinji, kana uchitsvaga zvinhu zvakanyatsonaka zvinogara kwenguva refu uye zvakavimbika, zvinhu zvakagadzirwa negranite chaiyo isarudzo yakanaka kwazvo. Hazvisi chete kuti zvakasimba uye hazviparadzi ngura, asiwo zvinopa kugadzikana kwakanyanya uye kururama kunogona kuchengetedzwa nekufamba kwenguva. Ungave uchishanda mukugadzira, mumotokari, mundege, kana chero imwe indasitiri inoda zvinhu zvakanyatsonaka, zvikamu zvegranite chaiyo zvichakupa mhedzisiro yaunoda.
