He kohatu taiao e whakamahia whānuitia ana te karāneti, ā, e mōhiotia whānuitia ana mō tōna pakari me tōna pumau, ā, he mea pai rawa atu mō ngā momo mahi hanga. He mea nui te tātari i te pakari me te pumau o ngā turanga karāneti hei mārama ki tā rātou mahi i raro i ngā āhuatanga taiao me ngā kawenga rerekē.
He toka mura te karāneti, he mea hanga tuatahi ki te quartz, te feldspar, me te mika, ā, e whai wāhi ana tēnei ki tōna kaha me tōna ātete ki te huarere. Ina tātarihia te pakari o ngā turanga karāneti, he maha ngā āhuatanga ka whai wāhi mai, tae atu ki te hanganga kohuke, te porousness, me te aroaro o ngā kapiti, ngā pakaru rānei. Mā ēnei āhuatanga ka whakatau te kaha o te karāneti ki te ātete i ngā tukanga huarere ā-tinana me te matū, pērā i ngā huringa huka-rewa, te ua waikawa, me te pakū.
Ko te tātari pumau e aro ana ki te kaha o te karāhe ki te pupuri i tōna hanganga pumau i raro i ngā kawenga maha, tae atu ki ngā kaha pūmau me ngā kaha hihiri. He mea nui tēnei i roto i ngā mahi pēnei i te hanganga rori, ina mahi ngā turanga karāhe hei paparanga turanga. He maha ngā wā ka whakahaerehia e ngā miihini ngā whakamātautau hei aromatawai i te kaha pēhi, te kaha kutikuti, me te modulus o te ngāwari o te karāhe, kia mōhio ai ka taea e ia te tautoko i te taumaha o ngā waka me te ātete i te whakarerekētanga i roto i te wā.
Heoi anō, me whai whakaaro ki te pānga ki te taiao ki ngā turanga karāhe. Ko ngā āhuatanga pēnei i te piki me te heke o te pāmahana, te makuku, me te pānga ki ngā matū ka pā ki te mahi roa o te karāhe. Mā te tiaki me te aroturuki auau ka āwhina i te whakaiti i ngā raruraru pea, kia mau tonu ai te pumau me te pakari o ngā turanga karāhe puta noa i tōna roanga o te ora.
Hei whakamutunga, he mea nui te tātari i te pakari me te pumau o ngā turanga karāhe hei whakarite i tōna whai huatanga i roto i ngā kaupapa hanga. Mā te mārama ki ngā āhuatanga o te karāhe me ngā āhuatanga e pā ana ki tōna mahi, ka taea e ngā kaihangarau te whakatau whai whakaaro hei whakarei ake i te roa me te pono o ngā hanganga i hangaia i runga i ngā turanga karāhe.
