Ko te Sunstone he mema motuhake o te rōpū feldspar, e whakarōpūtia ana hei momo plagioclase (pērā i te oligoclase, te labradorite rānei) he uaua ake rānei, he pāhare pāhare (orthoclase). Ko tōna āhuatanga matua ko tētahi āhuatanga whatu motuhake e kīia nei ko te aventurescence—he tīaho, he tīaho whakarewa ka puta i te wā e whakaata ana te mārama i ngā whakaurunga kohuke o roto. Ko ēnei whakaurunga he iti, he pereti-rite ngā tioata o te hematite, te goethite, te parahi māori rānei. Ko te tae taketake o te kōhatu whakapaipai mai i te kore tae me te kōwhai kōwhai ki te karaka hōhonu me te parauri-whero. I tua atu i tōna ātaahua, he 6.0 ki te 6.5 te pakeke o te sunstone i runga i te tauine Mohs, he mea mauroa e tika ana mō ngā mahi lapidary me ngā whakapaipai utu nui.
Ko te Whakapapa Whenua me te Tukanga Hanga
Ko te hanganga o te kōhatu rā e whai pūtake ana ki ngā tukanga hihiko, kino hoki e whai wāhi ana ki te hanga i te kirinuku o te whenua, inarā i roto i ngā taiao ahi whakamatao pēnei i ngā rerenga rangitoto pūtahi me ngā pegmatite kiripaka. I te wā e tīmata ana te whakarewa ahi ki te huri haere ki te toka mārō, ka tīmata ngā kohuke feldspar—otirā te oligoclase me te labradorite—ki te whakaputa tioata i roto i te whakarewa. I roto i tēnei wāhanga whakaputa tioata, ka mau ngā tohu maitai iti, tae atu ki te parahi me te rino, ki roto i te anga tioata e tipu ana. Kāore ēnei huānga e tohatoha ōrite; engari, i te heke tonu o te pāmahana me te pūmau o te hanganga tioata, ka pā te pūnaha ki tētahi āhuatanga e mōhiotia ana ko te whakaputanga. I roto i tēnei tukanga, ka wehe ngā katote maitai i mua i whakarewa ki te feldspar kaihautū, ka whakatikatika anō ki ngā pereti moroiti, ngā tawerewere rānei.
Kāore ēnei whakaurunga i te whai i tētahi aronga matapōkere. Nā te hanganga o roto o ngā tioata feldspar, ka whakarārangi ngā papa whakarewa ki ngā papa tioata motuhake, ka waihanga i tētahi hoahoanga o roto tino raupapa. Nā tēnei whakarārangi tika e puta ai te āhuatanga whatu e mōhiotia ana ko te aventurescence—he pīataata, he whakaataata i puta mai i te taunekeneke o te marama ki ngā papa whakarewa kua whakaurua. Ko te kaha, te tae, me te ātaahua o te kanohi o te tauira sunstone e tino whakawhirinaki ana ki te hanganga, te rahi, me te kiato o ēnei whakaurunga. Hei tauira, ko te sunstone o Oregon e tino whakanuia ana mō ōna tae whero, kākāriki, tae noa ki ngā pānga tae-rua, i puta mai i te noho o ngā papa parahi māori. Hei whakatairite, ko ngā sunstone mai i ngā rohe pērā i Inia, Nōwei rānei, e whakaatu ana i ngā whetū kōura, hiriwa rānei nā te whakaurunga o te waikura rino. Nō reira, ko ia sunstone he pūkete ā-whenua, e tiaki ana i roto i tōna hanganga te hītori wera me te taiao matū o tōna hanganga.
Te Hiranga o Mua me te Whanaketanga Ahurea
I roto i ngā hītori, ko te kōhatu rā (sunstone) he kaupapa e pā ana ki ngā kōrero tuku iho me te whaihua mahi puta noa i ngā ahurea maha. Ko tētahi o ngā ariā hītori tino nui ko te “Kōhatu Rā” a te Viking (sólsteinn), e whakahuahia ana i roto i ngā kōrero tuku iho o Tiorangi o te wā waenga. E whakapaetia ana i whakamahia e ngā kaiwhakatere o Norse ngā āhuatanga whakawehe o ētahi kohuke—pēnei i te kōhatu rā, te kōhatu Tiorangi rānei—ki te kimi i te tūnga o te rā i roto i te kapua mātotoru, i te atapō rānei, e taea ai ngā haerenga whakawhiti moana me te kore e kitea te rā. I tua atu i te hītori moana, he wāhi anō tō te kōhatu rā i roto i ngā pūrākau taketake o Amerika ki te Raki, i reira e honoa ana ki ngā atua o te rā, ki ngā wairua tīpuna rānei. Ahakoa i whakaarohia he kohuke onge, he kohuke tāwāhi puta noa i ngā rautau 18 me 19, nā ngā kitenga hou i ngā rohe pēnei i te Hononga o Amerika, Tanzania, me Ahitereiria, kua taea e te kōhatu rā te huri mai i te mea whakamīharo tuku iho ki te kōhatu utu nui e mōhiotia ana e te ao.
Te Hanganga Karaihe o te Rākōhatu
Ko te Sunstone he momo o te roopu feldspar, e whakarōpūtia ana hei momo plagioclase pērā i te oligoclase, te labradorite rānei, he iti ake rānei hei pāhare pāhare pērā i te orthoclase. Ko tōna hanganga karaihe he tectosilicate, e mau ana i te anga ahu-toru e tiritiri ai ngā ngota hāora katoa i waenga i te rua o te silicon Si, te konumohe Al rānei. I roto i te raupapa plagioclase, ko tēnei anga he otinga mārō i waenga i te albite NaAlSi₃O₈ me te anorthite CaAl₂Si₂O₈. Ko tēnei whakaritenga ka puta he pūnaha karaihe triclinic, e tautuhia ana e ngā tuaka rerekē e toru e whiti ana i ngā koki kōpīpī. Ko te āhuatanga whatu matua o te sunstone, e mōhiotia ana ko te aventurescence, ka puta mai i ngā whakaurunga kohuke tuarua, kaua i te whatu silicate ake. I te whakamatao o te magma kāinga, ka wehe ngā huānga tohu pērā i te rino, te parahi rānei, ka wehe atu i te hanganga feldspar, ka puta he kirikiri moroiti, he pereti-rite. Ko ēnei whakaurunga he hematite α-Fe₂O₃, he goethite, he parahi māori Cu rānei.
Ko ēnei kongakonga whakarewa e whakarārangi hanganga ana ki ngā papa wehenga, ki ngā aronga tioata motuhake rānei o te feldspar kaihautū. Ko te kōhatu rā e whakaatu ana i ngā aronga e rua o te wehenga tino pai e whiti ana i te 90°, e whakarato ana i ngā papa tinana e tau ai ēnei whakaurunga hei whakanui i te whakaata o te mārama. Ina uru te mārama ki roto i te kōhatu utuā nui, ka pā ki ēnei papa whakarewa whai aronga, ka puta te pīataata, te kanapa e wehewehe ai te kōhatu rā i ngā momo feldspar noa.
Ngā Āhuatanga Tinana me te Āhua Whatu
Ko ngā āhuatanga tinana me te āhua o te kōhatu rā e puta mai i tōna hanganga matū hei mema o te rōpū feldspar. I te taha tinana, ko tōna pakeke Mohs i te nuinga o te wā kei waenganui i te 6.0 ki te 6.5, ā, ko tōna taumaha motuhake kei waenganui i te 2.62 me te 2.72. Ko tētahi āhuatanga hanganga matua ko tōna wehenga tino pai ki ngā aronga e rua e tata ana ki te 90°, e whakaawe ana i te āhua o te tapahi i te kōhatu. Ko tōna kanapa e kīia ana he kanapa karaihe ki te kanapa iti, ā, ka waiho tonu e ia he kiriweti mā. I te taha ā-whatu, ko te kōhatu rā e mōhiotia ana mō te aventurescence, he pīataata e puta mai i te whakaata o te mārama mai i ngā whakaurunga moroiti, pēnei i te hematite α-fe₂o₃, te parahi māori Cu rānei. Ka mahi ēnei whakaurunga hei whakaata iti e hanga ai i te pīataata konganuku, te tiaho rānei ina hurihia te kōhatu. Ko te taupū whakaata i te nuinga o te wā kei waenganui i te 1.525 me te 1.552, ā, he biaxial te kōhatu. Ahakoa he mārama ki te pōuri te nuinga o ngā tauira, ko ngā kōhatu rā o te kounga teitei ka tata mārama, e whakaatu mārama ana i ngā kongakonga pīataata o roto.
Ngā Momo me te Hanganga o ngā Whakauru o te Kōhatu Rā
Ko ngā momo kōhatu rā o te sunstone e whakarōpūtia ana i runga i te tūāpapa o te kōhatu matua me te āhua o ngā whakaurunga o roto, e whakatau ana i te tae me te kanapa o te marama. Ko ngā momo noa ko te plagioclase sunstone, e kohia ana i Nōwei me Īnia, me te Oregon sunstone e tino whakanuia ana, e motuhake ana mō te parahi taketake kei roto. Ko tētahi atu momo motuhake ko te confetti sunstone, e mōhiotia ana mō ōna kongakonga hematite nui, kanapa e hanga ana i te āhua “confetti” tini tae. Ko te hanganga o ēnei whakaurunga he hua o te tukanga ā-papa e kīia nei ko te exsolution, e puta ana i roto i te taiao igneous e whakamatao ana. I te wā e whakataio ana te magma matua ki te feldspar, ka mau tonu ngā ngota konganuku whai tohu ki roto i te anga tioata o te kōhatu. I te hekenga o te pāmahana, ka heke te whakarewatanga o ēnei huānga whai tohu, ka wehe rātou i te hanganga feldspar, ka whakahekea hei papa konganuku moroiti motuhake.
Hematite α-fe₂o₃, Goethite rāneiKo ngā whakaurunga e kitea nuitia ana i ngā momo mai i Inia me Norewai, e puta ana hei kongakonga koura, he whero-parauri rānei.
Pāremata Koura CuKo tēnei momo whakaurunga onge te waitohu o te kōhatu rā o Oregon, e whakaputa ana i te whānuitanga o ngā tae tae atu ki te pītiti, te kākāriki, me te whero hōhonu, tae atu ki ngā pānga dichroic ahurei.
Ka mutu te hanga, ka whakatika tika ēnei whakauru pereti ki ngā papa wehenga hanganga o te feldspar kaihautū, e whakapūmau ana i te whakaata tahi o te rama hei whakaputa i te āhuatanga aventurescence.
Ngā Whakamahinga me ngā Whakamahinga Hou o te Kōhatu Rā
Ko te Sunstone he wāhi motuhake i te mākete o te ao, e whakawhānui ana i tōna whaihua mai i te hoahoa whakapaipai utu nui ki te rangahau pūtaiao me te tāpoi ahurea. I roto i te ao whakapaipai pai, e tino whakanuia ana te sunstone mō tōna āhuatanga aventurescence motuhake, e hanga ana i te tākaro whakamīharo o te mārama e kore e taea e ētahi atu kōhatu utu nui te whakaputa. Ko ngā kaihanga whakapaipai e rua ngā momo tapahi matua e whakamahia ana hei whakanui ake i tēnei pānga: ko ngā tapahi cabochon, e whakanui ana i te “kanapa” maeneene o ngā whakaurunga, me ngā tapahi faceted, e whakarei ake ana i te ahi me te kanapa o roto o te kōhatu. Ka whakauruhia ēnei kōhatu oti ki roto i ngā mowhiti, ngā taunga, me ngā whakakai taringa, me ngā tauira māramatanga teitei—otirā ngā momo parahi onge—e whakahaua ana ngā utu nui i waenga i ngā kaihoahoa whakapaipai me ngā tohunga mō ngā kōhatu utu nui. I tua atu i tōna whakamahinga ātaahua, he kaupapa nui te sunstone mō te rangahau kōhatu me te rangahau mātauranga. Hei mema o te rōpū feldspar, e whakarato ana i ngā mātai whenua ki ngā māramatanga matatika ki ngā tukanga o te whakatōpūtanga o te ahi me te whakaputanga o ngā huānga tohu i te wā e whakamātao ana te magma. Mā te tātari i te whakatakotoranga me te hanganga o ngā papa hematite, parahi rānei i roto i te anga silicate, ka taea e ngā kairangahau te mārama ake ki te hītori wera o ngā taiao puia i hanga ai ēnei kōhatu.
I roto i ngā wāhanga metaphysical me te wairua, ka whakamahia te kōhatu rā hei taputapu mō te whakamana whaiaro me te whakaora kare-ā-roto. He maha ngā wā ka whakamahia e ngā kaimahi te kōhatu i roto i te whakaaroaro, hei taonga whakamarumaru rānei, e whakapono ana ka āwhina ki te whakawātea i te ahotea, ki te whakatipu i ngā āhuatanga kaiārahi, me te whakaatu i te pūngao pai mā tōna hononga tohu ki te kaha o te rā. I tua atu, he wāhi nui te kōhatu rā ki te whanaketanga ōhanga ā-rohe me te tohu whenua. Hei tauira, ko te whakatairanga i te kōhatu rā hei kōhatu whenua i ētahi rohe kua whakakōkiri i te tipuranga o te “tūruhi kōhatu,” i reira ngā kaupapa mai i te maina ki te mākete me ngā wāhi keri tūmatanui e kukume ana i ngā kaingākau me ngā tūruhi, nā reira e tautoko ana i ngā ōhanga ā-rohe me te tiaki i te taonga tuku iho e pā ana ki ēnei “kōhatu o te rā.”
