I roto i te hanganga o tētahi tūāpapa rere hau pēhanga pūmau, he mea nui te whiriwhiri i te turanga ki te mahi whānui o te tūāpapa. He āhuatanga motuhake tō te turanga pūmau karāhe me te turanga rino maka, ā, he rerekētanga mārama i roto i ngā āhuatanga matua pērā i te pumau, te tiaki tika, te roa me te utu.
Tuatahi, te pumau: te hanganga matotoru me te hanganga whakarewa taiao
Whai muri i ngā miriona tau o ngā huringa whenua, ka honoa tata te karāneti e te quartz, te feldspar me ētahi atu kohuke hei hanga i tētahi hanganga tino matotoru, ōrite hoki. I te aroaro o ngā pokanoa o waho, pērā i te wiri kaha i puta mai i te whakahaere o ngā taputapu nui i roto i te awheawhe wheketere, ka taea e te turanga karāneti te aukati me te whakaiti mā te whakawhirinaki ki tōna hanganga karaihe matatini, ka taea te whakaiti i te kaha wiri o te papa rererangi hau pēhanga pūmau tika mā te neke atu i te 80%, ka whakarato i tētahi kokonga mahi pumau mō te papa kia pai ai te nekehanga i te wā tukatuka, i te kitenga rānei i te tino tika. Hei tauira, i roto i te tukanga whakaahua o te hanga maramara hiko, ka whakamanahia te tautuhi tika o ngā tauira maramara.
He mea whakarewa te turanga rino maka mai i te koranu rino-waro, ā, ko te karāpeti o roto he mea horapa hei pepa, hei porowhita rānei. Ahakoa he kaha tōna ki te whakaiti i te wiri, kāore tōna hanganga i te pai ki te whakataurite ki te karāneti. Mēnā he nui te kaha me te wiri tonu, he uaua ki te turanga rino maka te whakaiti i te pokanoa wiri ki te taumata iti rite tonu ki te turanga karāneti, ka arahi pea tēnei ki ngā rerekētanga iti i roto i te nekehanga o te tūāpapa hau rerehua pēhanga pūmau tika, ka pā ki te mahi tika o te tūāpapa i roto i ngā mahi tino tika.
Tuarua, te pupuri i te tika: ngā painga taiao o te iti o te whakawhanui me te wero o te huringa wera o te konganuku
E mōhiotia ana te karāhe mō tōna tauwehenga whakawhanui wera tino iti, ko te tikanga kei te 5-7 ×10⁻⁶/℃. I roto i te taiao piki me te heke o te pāmahana, kāore e tino rerekē te rahi o te turanga tika o te karāhe. I roto i te ao o te whetū, ka honoa te tūāpapa rere hau wai pūmau mō te whakatikatika pai o te karāhe karu tirotiro me te turanga karāhe, ahakoa he nui te rerekētanga pāmahana i waenga i te ao me te pō, ka taea e ia te whakarite kia mau tonu te tika o te tūnga o te karāhe i te taumata iti-micron, hei āwhina i ngā kaimātai whetū ki te hopu i ngā nekehanga ngawari o ngā tinana rangi tawhiti.
He tino teitei te tauwehenga o te whakawhānui wera o te rino maka, ko te tikanga he 10-20 ×10⁻⁶/℃. Ina huri te pāmahana, ka kitea te rerekētanga o te rahi o te turanga rino maka, ā, ka ngāwari te whakarerekē i te pāmahana o te papa rererangi pehanga pūmau, ka heke te tika o te nekehanga o te papa. I roto i te tukanga huri o ngā karāhe whatu aro-mahana, ko te whakarerekētanga o te turanga rino maka i raro i te awe o te pāmahana ka puta te peka o te tika o te huri o te karāhe ki tua atu i te awhe e whakaaetia ana, ā, ka pā ki te kounga o te karāhe.
Tuatoru, te roa: te pakeketanga teitei o te kōhatu maori me te ngenge o te konganuku
He teitei te pakeke o te karāhe, ka taea e te pakeketanga Mohs te eke ki te 6-7, he pai te ātete ki te kakahu. I roto i te taiwhanga pūtaiao rauemi, ko te tūāpapa rere hau pēhanga pūmau tino tika e whakamahia pinepine ana, ka taea e tōna turanga karāhe te ātete i te ngaronga waku mō te wā roa, ki te whakaritea ki te turanga noa, ka taea te whakaroa i te huringa tiaki o te tūāpapa neke atu i te 50%, te whakaiti i ngā utu tiaki taputapu, me te whakarite i te haere tonu o te mahi rangahau pūtaiao. Heoi, he pakarukaru te rauemi karāhe, ā, he tūponotanga ka pakaru ina pāngia tūpono.
He pakari te turanga rino maka, ā, kāore e ngāwari te whati ina mau i tētahi kaha pānga. Heoi, i roto i te tukanga nekehanga auau teitei o te papa rererangi pehanga pūmau mō te wā roa, ka ngāwari te rino maka ki te pakaru i te ngenge, ka hua ake he huringa ki te hanganga o roto, ka pā ki te tika o te nekehanga me te pumau o te papa. I taua wā anō, ka ngāwari te rino maka ki te waikura me te pirau i roto i ngā taiao makuku, ka whakaiti i tōna roa, he rerekē, he pai ake te ātete ki te waikura o te turanga karāhe.
Tuawhā, te utu hanga me te uauatanga tukatuka: ngā wero keri me te tukatuka kōhatu maori me te paepae tukanga whakarewa
He uaua te keri me te kawe i ngā rauemi mata o te karāhe, ā, he tino teitei ngā taputapu me ngā hangarau e hiahiatia ana mō te tukatuka. Nā te pakeketanga, he pakarukaru, he ngāwari te tapahi, te huri, te whakakanapa me ētahi atu tukanga ki te hinga, ki te pakaru, ki te tere para nui, ka hua ake he utu hanga nui.
He mea hanga te turanga rino maka mā te tukanga whakarewa pakari, he whānui ngā rauemi mata, ā, he iti te utu. Mā te pokepokea ai ka taea te whakatutuki i te whakaputanga papatipu, te whai huatanga whakaputa teitei. Heoi, kia tutuki ai te tino tika me te pumau rite tonu ki te turanga karāhe, he tino uaua ngā whakaritenga mō te tukanga whakarewa me te tukatuka i muri i te whakarewatanga, me te hiahia kia tino tika te miihini me te maimoatanga tawhito, ā, ka piki ake hoki te utu.
Hei whakarāpopototanga, he nui ngā painga o te turanga tika o te karāhe i roto i ngā horopaki tono o te tūāpapa hau mānu pēhanga pūmau e hiahia ana kia tino tika, kia pumau, kia ātete hoki ki te kakahu; he painga anō hoki o te turanga rino maka i roto i te utu me te pakari, ā, he pai mō ngā wā he iti noa ngā whakaritenga tika, he whai i te whai huatanga utu, ā, he pumau te taiao wiri me te pāmahana.
