Ko te Gadolinite he kohuke onge, matatini hoki o te matū, he kohuke sorosilicate e mau ana i te whenua onge, me te whānui o te pūtake (Ce,La,Nd,Y)₂FeBe₂Si₂O₁₀. Koia tētahi o ngā kohuke whenua onge tino nui o te hītori, ā, he wāhi nui tōna ki te kitenga me te rangahau i ētahi o ngā pūmotu lanthanide. He nui ngā kukū o te yttrium, te cerium, te lanthanum, te neodymium, me ētahi atu pūmotu whenua onge e kitea ana i roto i te kohuke, nā reira he kaupapa nui mō te rangahau kohuke me te matū whenua. Ko te Gadolinite e puta ana hei tioata prismatic, hei whakahiato kirikiri, hei āhua papatipu rānei e whakaatu ana i te tae pango, te kākāriki pouri, te parauri-pango, te kākāriki-pango rānei. He kanapa karaihe ki te hinuhinu tōna, he pakeke e 6.5–7 i te tauine Mohs, ā, he taumaha motuhake tiketike nā te nui o ngā pūmotu whenua onge taumaha.
Ko tētahi o ngā āhuatanga tino motuhake o te Gadolinite ko tōna kaha ki te huri hei metamict, he āhuatanga ka puta mai i te roa o te whakapā atu ki te iraruke o roto e tukuna ana e ngā tohu iti o te toriuma me te uranima kua whakaurua ki roto i te anga karaihe. I roto i ngā miriona tau, ka taea e tēnei iraruke māori te whakakore i te hanganga karaihe taketake, te huri i te kohuke ki tētahi āhua kore-hanganga, engari ka mau tonu te āhua o waho o te karaihe. Nā tēnei āhuatanga motuhake i noho ai te Gadolinite hei kohuke nui hei ako i te pānga iraruke, te pūmau o te karaihe, me te whanonga ā-āhuwhenua o ngā kohuke kei roto ngā whenua onge.
Ko te Gadolinite e whakaputa ana i roto i ngā pegmatite kirikiri tino whanake, ngā pūhui toka kawakawa kawakawa, me ētahi atu taiao whenua e whakarangatira ana i ngā huānga onge. Ko ēnei toka e tohu ana i ngā wāhanga whakamutunga o te whakatōpūtanga o te magma, i reira ka kaha te whakakotahi o ngā huānga kore hototahi pēnei i ngā huānga whenua onge, te beryllium, te zirconium, te fluorine, me te niobium ki roto i ngā wai magma toenga. I te wā e whakamātao haere ana ēnei wai whai-kōwhai i raro i ngā tikanga pai, ka whakatōpūtia te Gadolinite ki te taha o te whānuitanga o ngā kohuke āwhina, tae atu ki te zircon, te fluorite, te allanite, te xenotime, te monazite, me te beryl. Ko te kohuke e tino piri ana ki ngā pūnaha pegmatite kua whai i te rerekētanga matū whenua whānui, e taea ai te whakaemi o ngā huānga onge ki ngā taumata tiketike noa. Nā te mea he maha o ēnei taiao e whakarangatira ana i ngā huānga iraruke pēnei i te thorium me te uranium, ka pā te Gadolinite ki te panoni hanganga mā te metamictization i muri i te whakatōpūtanga. Nō reira, ka noho te kohuke hei tohu whai hua mō te whakamineralatanga o ngā whenua onge, ā, ka hoatu ki ngā kaimātai whenua ngā māramatanga nui e pā ana ki te whanaketanga o ngā pūnaha pegmatite, te nekeneke o ngā huānga whenua onge, me ngā pānga roa o te iraruke māori ki ngā hanganga kohuke.
He iti noa ngā kohuke i pā nui ake ki te whanaketanga o te mātai matū hou i a Gadolinite. I kitea tuatahitia te kohuke i te tau 1787 e te āpiha ope taua Huitene me te tohunga kohuke runaruna a Carl Axel Arrhenius i te kari Ytterby rongonui i Huitene, he wāhi ka rongonui ā muri ake mō te whakaputa kohuke i āwhina ki te kitea o te maha o ngā pūmotu whenua onge. I whakahaerehia ngā rangahau matū o te tauira e te tohunga matū Finnish a Johan Gadolin, nāna i tautohu tētahi wāhanga waikura kāore i mōhiotia i mua, ka kīia ko yttria. Hei whakanui i tana mahi whakahirahira, i whakaingoatia te kohuke ko Gadolinite i te tau 1800.
Ko te Hanganga Karaihe o Gadolinite
Ko te Gadolinite, e tino kitea ana ko te momo gadolinite-(Y) me te gadolinite-(Ce), he hanganga karaihe monoclinic uaua, ā, no te rōpū gadolinite i roto i te rōpū iti o te datolite o ngā kohuke sorosilicate. Ko tōna anga karaihe he mea hanga mai i ngā tetrahedra (SiO₄)⁴⁻ me (BeO₄)⁶⁻ e hono tahi ana hei hanga i ngā rōpū (Si₂Be₂O₁₀) e kitea ana, e honoa ana e ngā kātioka ferrous iron (Fe²⁺) kua whakaritea, ā, e whakapūmau ana e ngā wāhi nui o ngā whenua onge e nohoia ana e te yttrium, cerium, lanthanum, neodymium, me ētahi atu lanthanides. Nā tēnei whakaritenga ahurei ka puta he anga silicate-beryllate ahu-toru e whakaatu ana i ngā āhuatanga i waenganui i ngā neosilicates me ngā sorosilicates, e whai wāhi ana ki te pakeke, te kiato, me te pūmau o te matū o te kohuke. He nui te whakakapinga i waenganui i ngā whenua onge i roto i te hanganga, e puta ai he rerekētanga nui o te hanganga, e whakaawe ana i ngā āhuatanga tinana me te karaihe o te kohuke. Ko ngā tioata e tino hanga ana he rite ki te pou, ā, ka whakaatu pea i te whakawehenga o roto e whakaata ana i ngā āhuatanga whenua matū e huri ana i te wā e tipu ana. Ahakoa te pūmau o tōna anga karaihe, e tino mōhiotia ana te gadolinite mō tōna pāpoto ki te metamictization, he tukanga e puta ana i te pirau iraruke roa o te thorium me te uranium e whakaurua ana ki roto i te kohuke. I roto i ngā miriona tau, ka pākia te hanganga karaihe e ngā tukunga matūriki-alpha, e whakakore ana i te raupapa o ngā ngota, e huri ana i te rawa karaihe taketake ki tētahi āhua wāhanga, tino kore rānei, i te wā e tiaki ana i te āhua o waho o te tioata. Ka taea e tēnei āhuatanga te whakarerekē i te whanonga whatu, te kiato, me ngā āhuatanga mīhini o te kohuke, e waiho ai te gadolinite hei tauira matua e whakamahia ana i roto i te rangahau kohuke hei tirotiro i te pāpoto o te hanganga i te iraruke, te whanaketanga o te matū-karaihe, me te pūmau roa o ngā kohuke e mau ana i ngā whenua onge i roto i ngā taiao whenua.
Ngā Tāhu me ngā Āhuatanga Whatu
Ko te Gadolinite e mōhiotia ana mō tōna tae pōuri me te ātaahua, e kitea whānuitia ana i roto i ngā tae pango, pango-mātātoka, pango-parauri, parauri-pōuri, rānei oriwa kākāriki hōhonu. Ko ngā tioata hou, kāore anō kia panonitia, ka puta he tae kākāriki ngāwari ina tirohia i raro i te mārama kaha, ko ngā tauira kua pākia e te huarere, e te metamict rānei, ka pōuri ake, ka kore e kitea te mārama. He kanapa karaihe ki te kapia te āhua o te kohuke, e whakaatu ana i te kanapa o ngā mata tioata kua orohia. Ahakoa he pōuri te nuinga o ngā tauira ringaringa, ko ngā kongakonga angiangi, ko ngā tapa tioata rānei, ka taea te kitea te mārama ki te kākāriki-mārama, inarā i roto i ngā rawa kāore i tino panonitia. Ka puta i te Gadolinite he kiri hina-mā ki te kākāriki-hina mā, ā, kāore e kitea te whitiāhua i raro i te rama ultraviolet. I runga i te tirohanga whatu, he anisotropic te gadolinite tioata nā tōna hangarite monoclinic, ā, he nui ngā taupū whakaata, e whakaatu ana i te nui o ngā pūmotu whenua-uke taumaha me te rino. Heoi, nā te mea he maha ngā tauira kua pākia e te metamictization nā te pirau radioactive o roto, he maha ngā āhuatanga whatu kua pākia, kua kore e tika, e whakahekea ana te birefringence me te whakaiti i te raupapa tioata. I raro i te tirohanga moroiti, ko ngā tioata e tiakina pai ana ka whakaatu i te pleochroism ngoikore me ngā rerekētanga tae paku e pā ana ki te whakahōputu hanganga, ko ngā tauira metamict he maha ngā wā ka kitea he isotropic, he tata isotropic rānei ahakoa i ahu mai i te pūnaha tioata iti-hangarite. Ko ēnei āhuatanga whatu motuhake, me tōna tae pōuri me te kiato nui, e mōhiotia ai te gadolinite mai i ētahi atu kohuke silicate e mau ana i te whenua-uke.
Ngā Āhuatanga Tinana me te Matū
Ko te Gadolinite he kohuke onge, pakeke, me te matotoru e mau ana i nga whenua onge, e whakaatu ana i te huinga motuhake o nga ahuatanga tinana me te matū. Ko te tikanga he pakeke Mohs mai i te 6.5 ki te 7, e ahei ana ki te aukati i te warohanga e nga rawa noa i te wa e noho pakarukaru ana ki te whati i raro i te paanga kaha. He kino, he kore marama ranei te wehenga o te kohuke, a ka whati noa me te whati koretake ki te whati iti-koe. Ko tona taumaha motuhake kei waenga i te 4.0 me te 4.7, he nui ake i te nuinga o nga kohuke silicate na te mea kei roto nga huānga whenua onge taumaha, te rino, me etahi wa iti o te toriuma me te uranium. I runga i te matū, he kohuke rino-beryllium silicate uaua a gadolinite e whai rawa ana i nga huānga whenua onge, me te yttrium, te cerium, te lanthanum, me te neodymium hei waahanga nui. He nui te whakakapinga huānga i roto i tona hanganga karaihe, e arai ana ki nga rereketanga nui o te hanganga i waenga i nga waahi rereke. He tino pumau te kohuke i raro i nga ahuatanga matawhenua noa, engari ka taea te huri haere ki nga kohuke whenua onge tuarua na roto i nga tukanga huarere me te waiariki. Ko nga huānga irirangi iti kua whakauruhia ki roto i te whakatakotoranga ka whakaputa i te metamictization, e arai ana ki te pakaru haere o te raupapa karaihe i roto i te wā matawhenua. Ka taea e tenei whakarereketanga te awe i nga ahuatanga tinana penei i te matotoru, te pakeke, me te whanonga whatu i te wa e tiaki ana i te ahua o waho o te kohuke. Na tona whai rawa i nga huānga whenua onge me te beryllium, ka noho tonu te gadolinite hei kohuke nui mo nga rangahau matawhenua matū, rangahau huānga whenua onge, me nga tirotirohanga ki te kukuwhatanga karaihe-matū i roto i nga taiao pegmatitic me te toka kawakawa.
Ngā Whakamahinga me te Hiranga o te Tikanga Wairua
Ahakoa kāore e keria nuitia te Gadolinite hei kōreko hokohoko nui, he nui tōna hiranga pūtaiao me te ōhanga hei puna māori o ngā huānga whenua onge (REEs), tae atu ki te yttrium, cerium, lanthanum, me te neodymium. Ko ēnei huānga he wāhanga matua i roto i te whānuitanga o ngā hangarau hou, pērā i ngā aukume mahi-nui, ngā pākahiko whakahou, ngā pūnaha laser, ngā whakawhitiwhiti muka-ata, ngā whakaōwehenga, me ngā taputapu hiko matatau. Nā reira, he tino whai pānga te Gadolinite ki ngā kaimātai whenua me ngā kamupene keri e rapu ana i ngā putunga huānga whenua onge. I tua atu i tōna hiranga ahumahi, e tino whakanuia ana te kohuke e ngā kaikohi kohuke nā tōna onge, tōna hiranga hītori, me tōna hononga ki te kitenga o ētahi huānga whenua onge. Ko ngā tauira tioata pai mai i ngā wāhi tawhito e tino rapuhia ana e ngā whare taonga me ngā kohinga tūmataiti, i te wā e ako tonu ana ngā kairangahau i te kohuke mō ngā māramatanga ki te whanaketanga o te pegmatite, te matū whenua o ngā huānga onge, me te panonitanga hanganga i whakaaweawe iraruke.
I roto i ngā tikanga metaphysical me te whakaora karaihe, ka whakaarohia a Gadolinite he kōhatu o te panonitanga, te tipu hinengaro, me te tūhuratanga o roto. E whakapono ana ngā kaimahi ko tōna hononga kaha ki ngā huānga whenua onge me tōna hītori matawhenua hōhonu e tohu ana i te mātauranga huna, te whanaketanga whaiaro, me te whakapuakitanga o te pūmanawa huna. He maha ngā wā e honoa ana ki ngā pūngao whakapūwhenua i te wā e whakatenatena ana i te māramatanga teitei, te aroā, me te māramatanga wairua. Ka whakamahia e ētahi kaingākau karaihe a Gadolinite i te wā o te whakaaroaro hei whakatairanga i te tūhuratanga whaiaro, te taurite kare-ā-roto, me te tuku i ngā tauira whakaaro tawhito, e kite ana hei whakakōkiri mō te panonitanga pai me te whanaketanga whaiaro. Nā tōna tae pōuri me te pūngao whakapūmau e kitea ana, ka honoa hoki te kōhatu ki te whakamarumaru me te kaha ā-wairua. Heoi, ko ēnei whakamāoritanga metaphysical e hāngai ana ki ngā whakapono wairua me ngā tikanga ahurea, kaua ki te taunakitanga pūtaiao, ā, ko te hiranga matua o Gadolinite e mau tonu ana ki tōna hiranga mineralogical, geological, me te hītori.
