Ko te cuprite he kōhatu hāora parahi (copper(I) oxide) me te kōhatu tuarua nui e kitea ana i roto i ngā rohe whakapākahukahu o ngā putunga parahi. Ka puta mai i te hāora kōriri matū o ngā whāranui parahi tuatahi, pērā i te chalcopyrite, ina pā atu ki ngā taiao o te rangi e kī ana i te hāora mō ngā wā roa o te whenua. I te nuinga o te wā, ka puta mai tēnei hātepe parakinī i te whakatioata o te cuprite i te taha o ētahi atu kōhatu tuarua pērā i te malachite, te azurite, me te parahi māori. He maha ngā wā ka whakaatu ēnei tioata i ngā āhua rite, tae atu ki ngā āhua pūtoru me ngā āhua waru, kia pēnei te tuhi ki te: Pukapuka Whakamārama o te Mātai Kohuke Ka whakaatu pinepine ēnei tioata i ngā āhuatanga isometric, tae atu ki ngā āhua pūtoru, octahedral rānei.
Ko te whakaingoa o te momo i ahu mai i te kupu Rātini cuprum, e whakamāori tika ana ki te “parahi,” e whakaata ana i te nui o te konganuku me tana hanganga matū matua. Ahakoa he kohua iti o te parahi, ko tana hiranga kohatu whakapaipai kei roto i te taupū whakaata whakahirahira o 2.849, e runga ake ana i tō te taina. Heoi, nā te iti o tana pakeke Mohs i te 3.5 ki te 4.0, ka tino whakataua te cuprite hei kohatu whakapaipai a te kaikohi, kaua ki te whakamahi i roto i ngā whakapaipai tawhito. Ko tana tae whero hōhonu me te kanapa pērā i te taina te mea nui hei āhuatanga tautuhi mō te tautuhitanga i te wāhi mahi, e ai ki te tuhituhinga. Mindat.org pātengi raraunga kōhuke.
Ngā Āhuatanga Whatu me ngā Āhuatanga Tirohanga
He mea tuatahi te kupita e tōna āhua tino kaha te whakawhero, ko te nuinga e whakaatu ana i ngā tae whero parahi hohonu ki te whero-parauri. Ko tēnei tae he hua tika nō te nui o te parahi i roto me tōna matū karaihe motuhake, e taea ai te whānuitanga o ngā āhua mai i te whero mārama, kanapa—e whakatauritea ana ki te rupi pai—ki te pango konganuku āhua pōururi i roto i ngā tauira nui ake, mātotoru ake. Ina mātakina i roto i ngā kongakonga angiangi, i runga rānei i te mārama whakawhiti kaha, ahakoa ngā karaihe tino pōuri, e kitea ana tētahi ahi o roto whero kaha hei tohu.
Ko te āhua ataata o tēnei momo e whakarei ake ana i te tīrairaka o te whatu ki te pīataata o te parāone ki te konganuku, he hua nō te teitei o tōna taupū whakaata. Ina tīhorehia, ka puta mai te kanapa o te cuprite kounga-kohatu e taea ai te eke ki runga ake i te taimana, ahakoa he tino pāpaku te putanga o taua mea mārama. I tua atu i te āhua tioata noa, ka puta mai te cuprite i ētahi wā he momo ngongo e kīia nei ko te chalcotrichite, he huinga tioata ngira-rite pōtae, e whakaatu ana i tōna āhua hiraka motuhake.
Pūmau me te Whakamahi Kohatu
I roto i ngā mahi ahorangi, he nui ake te kitea o te kupiriti i roto i ngā kohinga kohuke i ngā whakapaipai arumoni nā ōna here ā-tinana. Ki te taumata pakeke o Mohs 3.5 ki te 4.0, he tino ngāwari te momo nei ki te whakangaueue me te horo mata, nā reira kāore e tino pai mō ngā tono pēnei i te kōhatu rīngi. Ahakoa ko ngā tāhei kākā, whakatārei, me ngā pine he kōwhiringa iti ake te tūponotanga, me whai whakatakotoranga tiaki te whakapaipai hei pupuri i te kaha o te kōhatu.
Ko te nuinga o ngā tioata kupirite e kitea ana he iti te rahi, he pōuri rawa rānei, e whakawhāiti ana i te tika mō te hanga mata. Heoi, he maha ngā wā ka puta te kupirite hei wāhanga o ngā whakakotahitanga o ngā kōhatu maha, tae atu ki ētahi atu kōhatu parahi tuarua pērā i te maraheiti, te hiriokora, me te atūrait. Ko ēnei tauira kōhatu whakauru e tino uaratia ana e ngā kaiwhakairo kōhatu, ka mahia e rātou hei kāpōhona hei whakaatu i ngā tātaritanga tae me ngā tauira motuhake e puta mai ana i ngā momo parahi maha.
Te Whakaingoa me te Whakamanatanga
Hei tautohu i te cuprite, ka tātarihia e ngā tohunga kohatu whakapaipai ōna tauwehenga tinana me te whatu tino nui, e wehewehe ana i a ia mai i ngā kohatu whero noa ake pērā i te garnet, te ruby, te spinel rānei. Ko te tohu tino whakapūmau ko tōna taupū whakaata tino nui o te 2.848—he nui ake i tō te taimana—e hanga ana i te kanapa konganuku kikorangi ngāwari i raro i te marama whakaata, i te marama whakawhiti e whakaatu ana i tōna tae kiri whero hōhonu. Waihoki, he tino mātotoru te cuprite, he taumaha motuhake i waenga i te 6.0 me te 6.14. Ko tēnei mātotoru nui e āwhina ana ki te wehewehe i a ia mai i ētahi atu kohuke whero "kei tua o te rohe" (OTL) pērā i te proustite, te wulfenite rānei. Hei kohuke inerua, he kotahi tōna whakaata, ahakoa ka puta pea he whakaata rerekē nā te pēhanga mata mai i te whakakānapa taimana tuku iho; ko ngā rangahau ngaio e kī ana kia whakamahia ngā wai waikawa silica hei pupuri i tōna pono whatu.Engari kua whakahiatotia te cuprite mō ngā rangahau ahumahi me te whakaora whaipara, kāore te rauemi whakatipu i whakamahia nuitia i te mākete kohatu whakapaipai. Ko ngā mea whaihanga o mua ko te karaihe "Maple Stones" kua whakakorehia te karaihe, te pirepire karaihe rānei kua tae ki te pākurakura (I) waikura, engari ko te cuprite māori te paerewa mō ngā kaikohi. He tohu whakatau te rārangi parauri-whero engari kaua rawa e whakamātauhia ki ngā kohatu kua whakapaipaihia nā te mea he whakamātau whakamōtī. Nā te mea kāore e whakawhiwhia te cuprite ki ngā maimoatanga, whakapakari rānei, ka noho tonu tōna tautohu ki te whakapūmau i tōna matū waikura māori me ōna āhuatanga whakahaere marama whakamīharo.
He Cuprite rānei, he Garnet Whero rānei?
Ahakoa he rite te ahua o te cuprite me te garnet whero i te titiro tuatahi, he tino rerekee tonu nga kohuke. Ko te huarahi tino whaihua hei wehewehe i a raua ko te taumaha me te kanapa. He nui ake te papatipu o te cuprite i te garnet; ki te puritia e koe tetahi wahi o ia mea ki o ringa, ka kitea te cuprite he tino taumaha ake mo tona rahi. I tua atu, he kanapa konganuku, he “hinuhinu” ranei te kanapa o te cuprite, engari ko te garnet te tikanga he kanapa karaihe rite tonu ki te karaihe matapihi.
Ko tētahi atu rerekētanga matua ko te pūmau. He pakeke, he u anō hoki ngā garnets, he mea tino pai mō ngā whakapaipai o ia rā pērā i ngā mowhiti. Heoi, he tino ngohe te cuprite, ā, ka taea te rakuraku mā te whao maitai, mā te moni parāhi noa iho rānei. Ki te tiro koe i ngā tioata i tō rātou ahua māori, ka kitea te cuprite e tipu tahi ana me te malachite kākāriki, te azurite kikorangi rānei—he huinga e kore koe e kite i ngā garnets. Hei whakakapi, ahakoa ka taea te ine i ngā āhuatanga o te marama o te garnet mā ngā taputapu paerewa, he nui rawa te kaha whakapiko marama o te cuprite ka “eke ki waho i ngā tūtohu” mō te nuinga o ngā taputapu whakamātau kōhatu utu nui.
Kei te noho tonu a Cuprite hei momo motuhake i te ao kohuke, e tino tohua ana e ona taumata tiketike o te ao me te tinana. Ko tona taupū whakaata, e nui ake i te taimana, me tona kiato nui e ahu mai ana i te parahi, e mea nui ana ki te hunga tohunga kohatu me te hunga kohi kohuke. Ahakoa tona ngawari ake e whakaiti ana i tana whakamahinga i roto i nga whakapaipai o ia ra, ko enei here ano e whakanui ana i tona mana hei kohatu’s motuhake mo te hunga kohi. Ahakoa e tirohia ana hei tauira kohuke mata, hei kohatu whakakoi ranei, he tauira marama a Cuprite o nga hua ataahua motuhake e puta mai ana i te waioranga o nga putunga parahi. Ko te mohio ki ana ahuatanga tirohanga—mai i tona kanapa whakarewa ki tona taumaha motuhake—he mea nui hei tautuhi tika me te whakatau uara i tenei kohuke waioranga onge i roto i te horopaki whanui o te tohunga kohatu.
