II roto i te ao rangahau pūtaiao, ko te āheinga ki te whakahoki i ngā raraunga whakamātautau he mea matua mō te ine i te pono o ngā kitenga pūtaiao. Mā te pokanoa o te taiao, te hapa ine rānei ka rerekē te hua, ā, ka ngoikore te pono o te whakatau rangahau. Nā ōna āhuatanga ā-tinana me ā-matū tino pai, ka whakarite te karāhe i te pumau o ngā whakamātautau i ngā āhuatanga katoa mai i tōna āhua rauemi ki te hoahoa hanganga, ā, he mea tino pai hei rauemi turanga mō ngā taputapu rangahau pūtaiao.
1. Isotropy: Te whakakore i ngā pūtake hapa kei roto i te rauemi tonu
He mea tito te karāneti i ngā tioata kohuke pērā i te quartz, te feldspar me te mika, he ōrite te horapa, e whakaatu ana i ngā āhuatanga isotropic tūturu. E tohu ana tēnei āhuatanga ko ōna āhuatanga ā-tinana (pērā i te pakeke me te modulus elasticity) he rite tonu ki ngā taha katoa, ā, e kore e puta he rerekētanga ine nā ngā rerekētanga hanganga ā-roto. Hei tauira, i roto i ngā whakamātautau miihini tika, ina whakatakotoria ngā tauira ki runga i te papa karāneti mō ngā whakamātautau uta, ka noho pumau te whakarerekētanga o te papa ahakoa te ahunga e whakamahia ana te kaha, ā, ka ārai i ngā hapa ine i puta mai i te anisotropy o te ahunga o te rauemi. He rerekē, he nui te anisotropy o ngā rauemi whakarewa nā ngā rerekētanga o te whakatakotoranga tioata i te wā tukatuka, e pā kino ana ki te ōritetanga o ngā raraunga whakamātautau. Nō reira, ko tēnei āhuatanga o te karāneti ka whakarite i te ōritetanga o ngā āhuatanga whakamātautau, ā, ka whakatakoto i tētahi turanga pakari mō te whakatutuki i te auautanga o ngā raraunga.
2. Te pumau o te wera: Ātete ki te pokanoa i puta mai i ngā huringa pāmahana
He tino pāngia ngā whakamātautau rangahau pūtaiao e te pāmahana o te taiao. Ahakoa ngā huringa pāmahana iti noa iho, ka taea e ngā rauemi te whakawhānui me te whakaiti i te wera, ā, ka pā ki te tika o te ine. He tino iti te tauwehenga o te whakawhānui wera o te karāhe (4-8 ×10⁻⁶/℃), he haurua noa iho tēnei o te rino maka, ā, kotahi hautoru atu i te koranu konumohe. I roto i te taiao he ±5℃ te piki me te heke o te pāmahana, he iti iho i te 0.04μm te huringa rahi o te papa karāhe kotahi mita te roa, ā, tata kore e arohia. Hei tauira, i roto i ngā whakamātautau pokanoa whatu, ka taea e te whakamahinga o ngā papa karāhe te wehe i ngā raruraru pāmahana i puta mai i te tīmatanga me te mutunga o ngā hauhautanga, ā, mā reira ka mau tonu te pumau o ngā raraunga i te wā e ine ana i ngā roangaru taiaho me te karo i ngā taupatupatu taha pokanoa nā te whakarerekētanga wera, ā, mā reira ka mau tonu te ōritetanga me te whakataurite o ngā raraunga i ngā wā rerekē.
III. Te kaha tino pai ki te pehi i te wiri
I roto i te taiao taiwhanga, he mea nui ngā wiri (pēnei i te whakahaere taputapu me te nekehanga o ngā kaimahi) e pā ana ki ngā hua whakamātautau. Nā ōna āhuatanga whakamātao teitei, kua riro te karāhe hei momo "ārai taiao". Ka taea e tōna hanganga karaihe o roto te huri tere i te kaha wiri ki te kaha wera, ā, ko tōna ōwehenga whakamātao he teitei ki te 0.05-0.1, he pai ake i ērā o ngā rauemi whakarewa (tata ki te 0.01 noa iho). Hei tauira, i roto i te whakamātautau karuārai matawai (STM), mā te whakamahi i te turanga karāhe, neke atu i te 90% o ngā wiri o waho ka taea te whakaiti i roto i te 0.3 hēkona noa iho, kia mau tonu te tawhiti i waenga i te matawai me te mata tauira, ā, kia mau tonu ai te ōrite o te hopu whakaahua taumata atomika. Hei tāpiri, mā te whakakotahi i te papa karāhe me ngā pūnaha wehe wiri pēnei i te puna hau, te whakanekehanga aukume rānei ka taea te whakaiti ake i te pokanoa wiri ki te taumata nanometer, ka whakapai ake i te tika o te whakamātautau.
IV. Te Pūmautanga Matū me te Pono mō te Wā Roa
He maha ngā wā e hiahiatia ana te whakamana roa me te whakahou i ngā mahi rangahau pūtaiao, nō reira he mea tino nui te whakaritenga mō te pakari o te rauemi. Hei rauemi he āhua pumau ngā āhuatanga matū, he whānui te awhe ātete pH o te karāhe (1-14), kāore e tauhohe ki ngā matū waikawa me ngā matū kawakore noa, ā, kāore e tuku i ngā katote konganuku. Nō reira, he pai mō ngā taiao uaua pēnei i ngā taiwhanga matū me ngā rūma ma. I taua wā, ko tōna pakeke teitei (te pakeke Mohs o te 6-7) me tōna ātete pai ki te kakahu ka iti ake te ngāwari ki te kakahu me te whakarerekē i te wā e whakamahia ana mō te wā roa. E whakaatu ana ngā raraunga kei te whakahaerehia tonutia te rerekētanga papatahi o te papa karāhe kua whakamahia mō ngā tau 10 i roto i tētahi whare rangahau ahupūngao i roto i te ±0.1μm/m, e whakatakoto ana i te turanga pakari mō te whakarato tonu i tētahi tohutoro pono.
Hei whakamutunga, mai i te tirohanga o te hanganga moroiti ki te mahi makoro, ka whakakorea e te karāhe ngā āhuatanga whakararuraru maha me ngā painga maha pēnei i te isotropy, te pumau wera pai, te kaha pehi wiri whai hua, me te roa o te mau o te matū. I roto i te mara o te rangahau pūtaiao e whai ana i te pakari me te taea te whakahoki, kua noho te karāhe, me ōna painga kore e taea te whakakapi, hei kaha nui ki te whakarite i ngā raraunga pono me te pono.
