Ko te Taaffeite he kohuke ōpaki o te konupūmā konumohe konupūmā konumohe me te tātai matū Mg₃BeAl₈O₁₆. Ka whakapakari i roto i te pūnaha tioata hexagonal, ā, kei waenganui matū i te spinel me te chrysoberyl. I runga i te tauine pakeke o Mohs, mai i te 8 ki te 8.5, ā, he tata ki te 3.60 ki te 3.62 tōna taumaha motuhake. Ki te titiro, mai i te mārama ki te mārama, e whakaatu ana i ngā tae pēnei i te māwhero kōmā, te māwhero, te waiporoporo, te māwhero, me ētahi wā he parauri, he kākāriki rānei. Kāore i rite ki te spinel, he isotropic me te whakaata kotahi, he uniaxially negative te taaffeite, ā, he ngoikore te whakaata rua (birefringence), he tohu mātua tēnei hei wehewehe i ngā kohuke e rua.
Ko te tautuhi i te taaffeite i puta mai i roto i te raupapa o nga mahi rereke i roto i te hitori o te kohatu whakapaipai. I te Noema o te tau 1945, i hokona e Richard Taaffe, he tohunga kohatu whakapaipai e noho ana i Dublin, Airangi, he kohinga kohatu whakapaipai kua tapahia e hokona ana hei spinels. I te tirotiro kanohi, i kite a Taaffe i tetahi tauira mawhero e whakaatu ana i te whakaraerae rua, e whakahē ana i te hanganga tioata pūtoru o te spinel pono. Hei tautuhi i te mea rereke, i tukuna tetahi wāhanga o te kohatu ki te Whare Taiwhanga o te Whare Tauhokohoko o Rānana, ā, i muri mai ki te Whare Taonga o te Ao Tūroa i Rānana. I whakapumautia e te whakamaarama X-ray me te tātari matū he momo kohuke hou tēnei mea kāore anō kia tuhia. I whakamanahia e te International Mineralogical Association i raro i te ingoa taaffeite i te tau 1951, me te tuhi koinei te kohuke hou tuatahi i kitea mai i te kohatu kua tapahia i mua.
Ko te ahua o te Taaffeite i raro i ngā āhuatanga paragenetic motuhake i roto i ngā rohe metamorphic taumata-tiketike, i ngā taiao whakapā hydrothermal rānei. Ka puta mai i ngā wā e pāhekoheko ai ngā pegmatites granitic e mau ana i te beryllium, ngā wai hydrothermal rānei, ki ngā toka waro e mau ana i te konupora, pērā i ngā dolomites me ngā skarns. Ko te whakataetae o te taaffeite e hiahia ana i tētahi taiao matū tika e whai rawa ana i te beryllium, te konupora, me te konumohe, me te iti rawa o te kukū o te hauhā silicon. Ki te nui te hauhā silicon i roto i te pūnaha, ka tauhohe te beryllium ki te hanga i ngā kohuke silicate pērā i te beryl, te chrysoberyl rānei. Nā te onge o ēnei herenga āhuatanga whenua e inaki ana, he iti noa ngā putunga tuatahi. Ko te nuinga o te kohuke ka whakahokia mai hei kirikiri alluvial i roto i ngā kirikiri kohatu o Sri Lanka me Myanmar, me ētahi putanga iti i kitea i Madagascar, Haina, me Tanzania.
Ngā Āhuatanga Tinana me te Matū o Taaffeite
Ko te Taaffeite tētahi o ngā kohuke kohatu tino onge e mōhiotia ana, ā, e tino whakanuia ana e ngā kaikohi kohuke me ngā kaingākau ki ngā kohatu utu nui. He pākawa konumohe konupora beryllium me te tātai matū e tika ana ko BeMg₃Al₈O₁₆, ā, nō te akomanga kohuke pākawa. Ka whakapakari te kohuke i roto i te pūnaha tioata hexagonal, ā, ka kitea i te nuinga o te wā hei tioata iti, hei kongakonga kohatu utu nui rānei kua whakaporoia e te wai. Ko te Taaffeite e puta ana i ngā tae mai i te māwhero kōmā, te rēneti, ki te waireti, te whero-waireti, ā, i ētahi wā kāore he tae. E whakaatu ana i te kanapa karaihe, te mārama ki te mārama āhua, me te kiri mā. Me te pakeke o Mohs e 8–8.5, he pakeke ake te Taaffeite i te kiripaka, ā, he ōrite ki te maha o ngā rauemi kohatu utu nui mauroa. Ko tōna taumaha motuhake e 3.60 ki te 3.65, ā, ko tōna taupū whakaata e taka ana i waenga i te 1.72 ki te 1.73. Ko tētahi o ngā āhuatanga tino nui o te Taaffeite mō te mātai kohatu utu nui ko tōna whakaata rua, e wehewehe ana i a ia i te spinel, he kohuke he ōrite te āhua engari he rerekē te whanonga whatu. I runga i te matū, he āhua pūmau te Taaffeite, ā, he ātete ki ngā tukanga hāora noa. Ka puta pea ngā whakakapinga iti o te rino, te chromium, te konutea, te konupora rānei i roto i tōna hanganga tioata, e whakaputa ana i ngā rerekētanga āhua o te tae me ngā āhuatanga whatu. He ātete te kohuke ki te wai me ngā waikawa ngoikore, ahakoa ko te rongo roa ki ngā waikawa kaha ka āta whakarerekē i tōna mata.
Ngā Whakamahinga me te Hiranga o te Taaffeite
Nā te mea he tino onge a Taaffeite, kāore e whai whakamahinga ahumahi, ā, ko tōna uara nui ko te mea he kōhatu whakapaipai me te kohuke kohikohi. Ko ngā tauira mārama tino kounga ka tapahia hei kōhatu whakapaipai whai mata, e tino rapuhia ana i te mākete kōhatu whakapaipai o te ao. Nā te iti o te tuku o ngā rawa kounga kōhatu whakapaipai, ka whakaarohia a Taaffeite he kōhatu whakapaipai a te kohikohi, kaua ko te kōhatu whakapaipai matua. Heoi anō, ko ōna tae ātaahua māwhero, rēneti, me te waireti, me tōna pakeke me te kanapa, e tika ana hei whakamahi i roto i ngā mōwhiti, taunga, whakakai taringa, me ētahi atu taonga whakapaipai pai. I tua atu i tana whakamahinga hei kōhatu whakapaipai, he nui te hiranga pūtaiao o Taaffeite i roto i ngā marama o te kohuke me te kōhatu whakapaipai. Ka rangahau ngā kairangahau i tana matū kirikiri, ōna āhuatanga whatu, me tana putanga matawhenua kia pai ake ai te mārama ki te hanganga o ngā kohuke onge e mau ana i te beryllium. Ka whakanuia hoki e ngā whare taonga me ngā whare mātauranga ngā tauira Taaffeite nā te mea e tohu ana rātou i tētahi o ngā kohuke kōhatu whakapaipai onge rawa atu i te ao. Nā reira, he tūranga motuhake tā te kohuke i te hononga o te rangahau pūtaiao, te kohikohi kohuke, me te whakanui i ngā kōhatu whakapaipai papai.
