Ko te pereti mata karāhe, e mōhiotia ana ko te tūāpapa tirotiro karāhe, he turanga tohutoro tino tika e whakamahia whānuitia ana i roto i ngā mahi whakaputa ahumahi, ngā taiwhanga, me ngā pokapū ine. He mea hanga mai i te karāhe tūturu kounga teitei, he tino tika, he pumau ngā āhuatanga, he ātete ki te waikura, he mea tino pai mō te whānuitanga o ngā tono ine me te whakatikatika.
Te Hanganga o ngā Rauemi me ngā Āhuatanga ā-Tinana
Ko ngā mea e whakamahia ana mō ngā papa tino tika ko:
-
Pirokene
-
Plagioclase
-
He iti noa te nui o te olivine
-
Mika biotite
-
Ākeneti whaiti
Mā ēnei wāhanga kohuke ka puta he tae pouri, he hanganga matotoru, he kakano ōrite ki te karāhe. I muri i te koroheketanga tūturu, ka tutuki i te kōhatu:
-
Te kaha pēhi teitei
-
Tino pakari
-
Te pumau nui i raro i ngā kawenga taimaha
Mā tēnei ka mau tonu te papatahi me te tika o te pereti mata, ahakoa i roto i ngā taiao ahumahi uaua.
Ngā Auahatanga Whakamahinga Hou: Te Papatahi i Runga i ngā Pūwāhi Pa
I ngā wā o mua, i aro nui ngā kaiwhakamahi ki te maha o ngā pūwāhi whakapā i te aromatawai i ngā pereti mata karāhe. Heoi, nā te tipu haere o te rahi me te uaua o ngā mea mahi, kua neke te umanga ki te whakatairanga i te papatahi o te mata.
I ēnei rā, ko te arotahi a ngā kaihanga me ngā kaiwhakamahi ki te whakarite i te ātete papatahi whānui, kaua ki te whakanui ake i ngā wāhi pa. Mā tēnei huarahi ka tukuna:
-
Te whakaputanga utu-whai hua
-
He tika rawaka mō te nuinga o ngā mahi ahumahi
-
Te urutau mō ngā taputapu me ngā mahi nui ake
He aha i whiriwhiri ai i te karāhe mō ngā mahi ine?
1. Te Pūmautanga o te Ahu
Ka pāngia te karāneti e te koroheketanga tūturu mō ngā miriona tau, ka whakakorea te ahotea o roto. Ko te hua he rauemi pumau, kāore e pirau, he mea tino pai mō te whakamahinga roa i roto i ngā taiao tino tika.
2. Ātete Matū me te Ātete Aukume
He ātete te karāneti ki ngā waikawa, ki ngā kawakore, ki te waikura, me te wawaotanga aukume, nō reira he pai mō ngā wāhi rokiroki matū, ngā rūma ma, me ngā mahi hanga hangarau matatau.
3. Te Whakawhanuitanga Wera Iti
Me te tauwehenga whānui wera i waenga i te 4.7 × 10⁻⁶ ki te 9.0 × 10⁻⁶ inihi/inihi, ka iti noa te pānga o ngā huringa pāmahana ki ngā mata o te karāhe, kia tika ai ngā pānui i roto i ngā āhuatanga rerekē.
4. Ārai-makuku, Kore-Waikura
Kāore i rite ki ngā momo konganuku kē atu, kāore te karāhe i te ātete ki te makuku, e kore hoki e waikura, nō reira he iti noa te tiaki me te roa o te ora mahi.
5. Te Pakari Pai me te Ātete ki te Mau
Ko te karāneti tētahi o ngā rauemi hanga tino pakari, he tino ātete ki te pakū ahakoa te whakamahinga auau.
6. Whakaotinga Mata Maeneene
Ka taea te huri kia miro pai te mata, ka orohia hoki, kia iti ai te taratara, he āhua whakaata, kia pai ai te pa atu ki ngā wāhanga kua inehia.
7. Manawanui Pānga
Mena ka rakurakuhia, ka pāngia rānei te mata, ka puta ake ngā rua iti i roto i te kereita kaua i ngā kohao, i ngā taha teitei rānei—kia kore ai e hē te āhua o ngā inenga matua.
Ngā Painga Tāpiri o ngā Pereti Tirotiro Granite
-
Kore-aukume, ā, kore-pūmau
-
He ngāwari ki te horoi me te tiaki
-
He pai ki te taiao, ā, he mea hanga ā-taiao
-
Kei te wātea i roto i ngā momo taumata me ngā rahi
Whakamutunga
He taputapu tūāpapa tonu te pereti mata karāhe i roto i ngā ahumahi tino tika o ēnei rā. Nā tōna tika o ngā āhuatanga, tōna pumau mō te wā roa, me tōna ātete ki ngā āhuatanga taiao, ka tautokohia e ia ngā tono mai i te miihini CNC ki te whakahaere kounga i roto i ngā hikohiko, te rererangi, me ngā taputapu.
I te tipu haere o ngā āhuatanga o ngā mea mahi me te uauatanga o te tirotiro, ka noho tonu ngā pereti mata o te karāhe hei otinga pono, whai hua hoki mō te pupuri i ngā paerewa ine teitei rawa atu.
