I roto i ngā mara o te hanga me te ahumahi, he whānui te whakamahinga o te karāneti nā tōna pakeke, tōna matotoru, tōna ātete ki te waikawa me te kawakore, me tōna ātete ki te huarere. Anei tētahi tātaritanga taipitopito māu mō te pānga o te tae o te karāneti ki tōna matotoru, me pēhea te whiriwhiri i te karāneti pumau ake i roto i te mara o ngā taputapu tika ahumahi.
Te whanaungatanga i waenga i te tae me te mātotoru o te karāhe
Ko te nuinga o te karāneti he mea hanga mai i ngā kohuke pēnei i te kuata, te feldspar me te mika, ā, ko tōna tae e whakawhirinaki ana ki ngā momo me ngā rahinga o ngā wāhanga kei roto. Mai i te tirohanga o te mātotoru, he hononga kei waenganui i te tae me te mātotoru, engari ehara i te hononga take tika.
Ngā rerekētanga o te hanganga kohuke: Te tae māramaHe maha ngā wā he nui te quartz me te feldspar i roto i te ranite, pērā i te hina-mā me te whero-kikokiko. He teitei, he pumau hoki ngā mātotoru o ēnei kohuke e rua. Ko te mātotoru o te quartz kei waenga i te 2.6 ki te 2.7g/cm³, ko te feldspar ia kei waenga i te 2.5 ki te 2.8g/cm³ i runga i te momo. Ko te nui o ēnei kohuke ka piki ake te mātotoru whānui o te karāhe mārama. Ko te karāhe pouri, pērā i te mangu me te kakariki, he maha ngā wā he nui te nui o ngā kohuke rino me te konupūmā me ngā kohuke pouri pērā i te amphibole me te biotite. Ko te mātotoru o te amphibole he tata ki te 3.0-3.4g/cm³, ā, ko te biotite he tata ki te 2.7-3.1g/cm³. Heoi, ina he nui ake ngā huānga konganuku taumaha (pērā i te rino me te manganese) kei roto i te karāhe pouri, ka piki ake tōna mātotoru.
Te nui o te whakatioata me te awe hanganga: Ka taea e te tae te whakaata i ngā rerekētanga o te nui o te whakatioata me te hanganga o te karāneti. Ko te karāneti he nui te whakatioata me te hanganga matotoru he rite tonu te tae, ā, he teitei hoki tōna matotoru. Nā te mea he tata te whakaritenga o ngā matūriki kohuke, ā, he nui te papatipu mō ia rōrahi. Ko te karāneti he ngoikore te whakatioata me te hanganga wetewete, tera pea he tae kōpikopiko, he koretake hoki, he maha ngā āputa o roto, ā, he iti te matotoru.
Te kōwhiringa karāhe i roto i te mara o ngā taputapu tika ahumahi
I roto i te ao o ngā taputapu tika ā-ahumahi, he tino teitei ngā whakaritenga mō te pumau mō te karāhe. I te nuinga o te wā, ka tīpakohia te karāhe tika mā te whakaaro whānui ki ngā āhuatanga maha:
Te hanganga me te hanganga o ngā kohuke: Ko te karāneti he nui te ihirangi me te tohatoha ōrite o te quartz me te feldspar te mea e pai ake ana. He pumau te hanganga o roto o tēnei momo karāneti, ka taea te whakaiti i te rerekētanga i puta mai i ngā huringa o te ahotea o roto, me te whakarite kia roa te mahi pumau o ngā taputapu. I taua wā, ko te karāneti he nui te tioata, he pai, he ōrite ngā matūriki, me te hanganga matotoru te mea e pai ake ana. I te whakamahinga roa me te tono kaha, ka taea e ia te pupuri i te tika me te whakaiti i te pānga o ōna ake huringa hanganga ki te tika o ngā taputapu.
Ngā tohu mahi ā-tinana: Me iti te tere mimiti wai o te karāhe, arā, he iti iho i te 0.5% te tikanga, hei ārai i ngā raruraru pēnei i te whānui o te rōrahi me te hekenga o te kaha i puta mai i te mimiti wai, ka pā pea ki te tika o ngā taputapu. Me iti te tauwehenga o te whānui wera. Ko te mea pai, me iti iho i te 8×10⁻⁶/℃ hei whakaiti i ngā huringa ā-ahu i puta mai i ngā rerekētanga pāmahana. Hei tāpiri, me teitei te kaha pēhi, arā, he nui ake i te 150MPa, kia taea ai te tu atu i ngā kaha rerekē i te wā e whakahaerehia ana ngā taputapu.
Ngā momo noa e taunakitia ana: Jinan Green Granite, Indian Black, South Africa Black me ētahi atu granite pango, he pouri te nuinga o te tae, he matotoru te hanganga, he iti te tauwehenga o te whakawhānui wera me te ātete pai ki te kakahu, ā, he pai mō ngā turanga o ngā taputapu tirotiro whatu me ngā whakaritenga tino teitei mō te tika me te pumau. Ko te granite ma hīhiama, he mārama te tae, he ōrite ngā matūriki kohuke, he pakeke me te kaha teitei, e whakamahia whānuitia ana i roto i ngā taputapu hanga maramara hiko, ā, ka taea te whakatutuki i ngā whakaritenga o te tūnga tino tika me te mahi pumau mō te wā roa o te taputapu.
Hei whakamutunga, ahakoa he hononga kei waenganui i te tae me te mātotoru o te karāhe, i te wā e whiriwhiri ana i te karāhe i roto i te mara o ngā taputapu tika ahumahi, me whai whakaaro whānui ki ngā āhuatanga maha pēnei i te hanganga kohuke, te hanganga, me ngā āhuatanga ā-tinana kia tino tika ai, kia pumau ai hoki ngā taputapu.
