Ko te Pyroxmangite he kohuke manganese silicate onge e whakaputa ana i roto i te pūnaha triclinic. Nō te rōpū pyroxenoid, he karaehe kohuke e mōhiotia ana mō ō rātou hanganga silicate mekameka kotahi. Ahakoa he uaua te wehewehe i te tirohanga kanohi mai i te rhodonite, ko te pyroxmangite e tautuhia ana e tētahi whakaritenga hanganga motuhake: ko ōna mekameka silicate he waeine tukurua e whitu ngā tetrahedra, i te mea ko te rhodonite e rima. Ko tēnei rerekētanga hanganga he mahi nui nā ngā āhuatanga pēhanga me te pāmahana i te wā o te hanganga o te kohuke, me te pyroxmangite e tohu ana i te polymorph pēhanga-tiketike, pāmahana-tiketike rānei o te manganese silicate.
Ko te ahua o te kohuke he kōwhai, he whero-āhua, he parauri-whero rānei. Ina pā te huarere ki a ia, ka puta he kiri pango, he parauri pango rānei o te waikura konupora ki runga i ōna mata. I tōna āhua parakore, he kanapa karaihe te kohuke, ā, he mārama ki te mārama. He 5.5 ki te 6 tōna pakeke Mohs, ā, e rua ngā huarahi e tino māwherangi ai, nā reira he pākaka te rawa, he uaua ki te mahi mō ngā whakamahinga ahumahi, whakapaipai rānei.
Ko te Takenga mai me te Hītori o te Pyroxmangite
Ko te hanganga o te Pyroxmangite ko te hua matua o te whakawhanaketanga teitei e mahi ana i runga i nga parataiao manganese-nui, i nga kohuke manganese o mua ranei, penei i te rhodochrosite me te quartz, i raro i nga tikanga thermobaric motuhake. Hei polymorph teitei-pehanga me te pāmahana-teitei o te silicate manganese, ko tona pumautanga e whakahaerehia ana e te kaha o nga kaha whenua; ina koa, ka piki ake nga taumata whakawhanaketanga, ka huri te mekameka silicate e rima-wae o te rhodonite ki te mekameka e whitu-wae uaua ake e tautuhi ana i te pyroxmangite. Ko tenei whakawhitinga ka puta i roto i nga whitiki whakawhanaketanga rohe, i nga waahi whakapiri ranei e whakarato ana nga whakaurunga igneous i te kaha waiariki e tika ana, i te nuinga o te waa i nga pāmahana e neke ake ana i te 400°C. I tua atu i te whakawhitinga ahua-totoka, ka taea hoki e te kohuke te whakaheke mai i nga wai hydrothermal manganese i a ratou e huri haere ana i nga whati o te kirinuku me te tauhohe ki nga toka a tawhio noa. I roto i enei mahinga, me noho iti te taiao geochemical i te konupūmā, na te mea ko te noho mai o te konupūmā ka huri ke te whakatipu ki nga kohuke penei i te bustamite, i te rhodonite konupūmā ranei, kaua ki te hanganga triclinic motuhake o te pyroxmangite.
Ko te rekoata o mua o Pyroxmangite i tīmata i te tau 1913, i te wā i kitea whānuitia ai e ngā tohunga kōhatu mai i ngā wāhi whenua e rua: te rohe o Iva i Anderson County, South Carolina, me te rohe maina o Långban i Huitene. I ahu mai te ingoa i te āhua o te kanohi me te āhua matū e rite ana ki te rōpū pyroxene me te nui o te konupora, ahakoa i whakaatu mai ngā rangahau X-ray diffraction i te waenganui o te rautau 1900, he uaua ake te hanganga “pyroxenoid” o roto i te mea i whakaarohia i te tuatahi. Mō ngā tekau tau, he maha o te pyroxmangite o te ao i hē te tohu hei rhodonite nā te mea he tata ōrite ngā āhua tinana; kāore i tae noa ki te whakamahine o te tātari hanganga kirikiri i ngā tau 1950 me 1960, i mōhiotia whānuitia ai te kōhatu hei momo motuhake e tautuhia ana e tōna mekameka silicate e whitu-wae. I tino whakarahi ake te hiranga o te kōhatu i te haurua whakamutunga o te rautau, i te kitenga o ngā tioata tino pai, kohatu tāonga i te rohe o Conselheiro Lafaiete i Parīhi me te Maina o Taguchi i Hapani. Nā ēnei kitenga i huri ai te pyroxmangite mai i te mea whakamīharo kōhatu iti e kitea ana i ngā hanganga rino-konupora whakarerekē, ki tētahi momo tino utu nui mō ngā kohinga kōhatu pūtaiao me ngā rangahau kohatu tāonga matatau.
Rhodonite vs. Pyroxmangite: He aha te Mea e Wehewehe Ai i a Rāua?
Ko te Rhodonite me te Pyroxmangite he rite tonu te ahua i te tuatahi, he rite te hanganga o te manganese silicate me te karaehe mawhero ki te whero-rose, engari ko te tino rerekētanga kei roto i o raatau hanganga karaihe o roto. Hei momo hanganga polymorphs, ka puta i raro i ngā āhuatanga matawhenua rerekē, e ārahi ana ki ngā whakaritenga ngota motuhake. Ko te Rhodonite he mea hanga mai i ngā mekameka silicate e tukurua ana i ia rima waeine tetrahedral, e hua ai he hanganga tuwhera ake, ko te Pyroxmangite he whirihora mātotoru ake me ngā mekameka e tukurua ana i ia whitu waeine—he tohu e puta ana i raro i te pēhanga teitei ake, i ngā āhuatanga pāmahana teitei rānei. E ai ki ngā āhuatanga tinana, ko te Pyroxmangite te tikanga he paku teitei ake tōna taupū whakaata me te taumaha motuhake, e paku mātotoru ake ai i te Rhodonite, ahakoa he ngāwari ēnei rerekētanga, kāore e māmā te kite. Ko ēnei kohuke e rua he kōhatu mawhero oraora me ngā uaua pango o te manganese oxide, engari ko te Pyroxmangite ka nui ake te puta i roto i ngā karaihe mārama, e rite ana ki te kounga kohatu utu nui, ahakoa he uaua. Ahakoa ēnei rerekētanga, ko te inaki o ō rāua āhuatanga e tino uaua ana te wehewehe mā te tirohanga kanohi, mā ngā taputapu gemological paerewa rānei, ā, ko te tautuhi tika e hiahiatia ana he tikanga taiwhanga matatau pēnei i te X-ray diffraction, i te Raman spectroscopy rānei hei whakatau mēnā e whai ana ngā mekameka silicate i te tauira e rima-waeine, e whitu-waeine rānei.
Ko te Tika me te Whakamahinga o te Pyroxmangite hei Whakapaipai
Ko te whakamahinga o te pyroxmangite ki roto i nga whakapaipai e herea ana e ona ahuatanga tinana, e noho ana hei rauemi motuhake mo nga kaikohi, kaua hei mea whakapaipai mo te maakete nui. Ahakoa he rite te tae whero-rose me te kanapa karaihe o te kohuke ki nga kohatu utu nui ake, ko tona pakeke Mohs o 5.5 ki te 6 ka waiho kia whakamamaetia e nga matūriki o te taiao. Ko te aukati hangarau nui rawa atu mo tona whakamahinga ki roto i nga whakapaipai ko tona wehenga tino pai me tona pakari ngawari; na enei ahuatanga ka tino uaua te hanga mata o te kohatu, ka ngawari hoki te wehe ina pa ki nga taumahatanga miihini o te whakaurunga whakapaipai tawhito. No reira, ahakoa ka tapahia etahi tauira maramara hei kohatu utu nui, e kiia ana he mea whakaatu, he mea ranei mo nga whakapaipai tiaki e kore e pa ki te tukinga nui.
I roto i ngā wāhanga pūtaiao me te whakapaipai, he maha ngā mahi a te pyroxmangite. I roto i te rangahau whenua, ko te kohuke nei he ine-pāmahana me te ine-pēhanga pono, nā te mea ko tōna noho i roto i ngā wae toka kua whakarerekētia e taea ai e ngā kaipūtaiao te tātai i ngā rōnaki pāmahana me te pēhanga motuhake i pāngia e te kirinuku o Papatūānuku i ngā wā o te hanga maunga. I roto i ngā mahi toi whakapaipai, ko ētahi momo pōuri ake, nui ake rānei ka mahia hei cabochon, hei whakairo whakapaipai rānei, ahakoa he iti ake tēnei i te whakamahinga o tōna hoa kaha ake, ko te rhodonite. Ko te mutunga ake, ko te uara matua o te pyroxmangite kei tōna tūranga hei tauira kohuke; ko ngā tioata kounga teitei he mea nui mō ngā pūranga whare taonga me ngā kohinga pūnaha, e tuku ana i te rekoata o te kanorau matatini matū me te hanganga e kitea ana i roto i ngā taiao kua whakarerekētia e te konupora.
