Ko te Prosopite he kohuke waipiro-fluoride onge, ko te konupūmā me te konumohe te nuinga o ōna pūtake. Ka puta i te nuinga o te wā i roto i te pūnaha tioata monoclinic, e whakaatu ana i ngā papatipu kore tae, mā, he kōwhai-mā pounamu rānei me ngā tioata papatahi. I runga i te āhuatanga o te whenua, ka puta te kohuke nei mā ngā tukanga panonitanga waiariki, e tupu ana i ngā uaua kawe tine, i ngā pegmatite tōnati rānei. He mea hanga i te nuinga o te wā e te whakapā atu o ngā wairewa whai fluoride nui ki ngā kohuke whai konumohe, pērā i te cryolite, i ngā wāhanga whakamutunga o te whakatioatatanga kohuke.
Ko te hītori o Prosopite e tīmata ana mai i te tau 1853, i te wā i whakamāramatia tuatahitia ai e te tohunga kōhatu Tiamana a August Breithaupt. Ko tōna ingoa i ahu mai i te kupu Kariki prosopon, e whakamāori nei ki te kanohi huna. Ko tēnei tikanga ingoa e tohu ana ki te āhua o te kōhatu nei ki te hanga pseudomorphs, i reira e whakakapi ana i te hanganga o roto o tētahi atu kōhatu, engari e pupuri ana i te āhua o waho o te kōhatu taketake, e huna tonu ana i tōna tuakiri pono. Ahakoa kāore e whai hua nui ki te ahumahi, he mea whai pūtaiao tonu mō tōna hanganga matū ahurei, ā, e tino whakanuia ana e ngā kaikohi kōhatu mō tōna onge me tōna hononga ki ngā wāhi keri rongonui i Tiamana, Kiriwhenata, me Mehiko.
Ngā rerekētanga ā-ahua o Prosopite
Ka puta te prosopite i roto i ētahi āhua tinana rerekē e whakaatu ana i ngā āhuatanga waiariki motuhake o tōna taiao. Nā te mea ka puta mai i te panoni o ngā kohuke o mua, ka taea tōna āhua mai i ngā hanganga tioata e mārama ana ki ngā āhua whakakapi tinihanga. I tōna āhua tino whanake, ka whanake te kohuke hei tioata iti, motuhake, he papatahi, he potopoto rānei te āhua, he rite ki ngā pereti iti e whakahuihui ana i roto i ngā kōhao o te toka kāinga. Heoi, i roto i te nuinga o ngā putunga, ka kitea noatia hei whakahiato papatipu, kiriiti rawa. Ko ēnei papatipu kōhatu, oneone rānei, he kōrakorako, ā, ka taea te kiko mai i te mātotoru me te pakeke ki te māngari, i runga anō i te mā o te tauira.
He ariā matua o te Prosopite ko tōna noho hei pseudomorph, e whakakapi ana i ngā tioata o ētahi atu kohuke, pērā i te cryolite, mā te whakakī i ō rātou āhua āhuahanga taketake. Ko tēnei āhua huna te take matua o te ingoa pūtaiao o te kohuke, ā, ka noho tonu hei kaupapa whakahirahira i roto i ngā rangahau pūtaiao kohuke. I tua atu, ka tipu ētahi wā te Prosopite hei anga whakamarumaru angiangi, hei kāhui muka hīrangi rānei i runga i te mata o ngā kohuke e pātata ana, ka puta ētahi wā i ngā āhua botryoidal me te kōpura maeneene o waho. Ahakoa he kore tae, he mā rānei te kohuke parakore, ka puta pinepine ia i ngā ātanga kōmā me te kōwhai, te kākāriki hoki. Ko ēnei momo tae he hua nō te whakaurunga o te parahi iti, nō te tata rānei ki ngā kohuke whai parahi, ā, tērā pea ka rite tōna āhua ki te turquoise.
He kōhatu utuā a Prosopite? Te mārama ki ōna whakamahinga me tōna uara ahumahi
Ko te Prosopite te nuinga e whakarōpūtia ana hei kohuke kohikohi onge, kaua hei kowhatu whakapaipai auraki. I roto i te matauranga kowhatu whakapaipai, he iti noa tana whakamahinga nā te āhua o ōna āhuatanga tinana, inarā ko te pakeke Mohs e 4 ki te 4.5. Nā tēnei taumata pakeke iti, ka ngāwari te kohuke ki te waruhia me te kakahu, kāore e tika mō ngā tono whakapaipai arumoni pērā i ngā mowhiti, porowhita rānei. Ahakoa ko ngā momo kākāriki me te kikorangi tiwhatiwha ka tapahia i ētahi wā hei kowhatu porotaka (cabochon), ka orohia rānei hei kowhatu oro, ko ēnei i te nuinga e whakaarotia ana hei tauira tāwaho mā ngā kaikohikohi motuhake. Ko ēnei momo āhua e rāhuitia ana mō te whakaatu, mō te whakamahi rānei i roto i ngā whakapaipai tiaki, pērā i ngā tārei, i te wāhi e iti ake ai te pānga o te tinana ki te kowhatu. Nā tōna āhua rite ki te turquoise i tōna āhua nui, ka akohia i ētahi wā hei tauira kape, ahakoa ko tōna onge te nuinga ka nui ake tōna wāriu hei tauira kohuke i tōna wāriu hei whakakapi mō te turquoise.
I waho atu i ngā mahi tārai kohatu, kāore he whakamahinga nui a Prosopite mō te ahumahi, mō te tauhokohoko rānei. Kāore e tupu ana i roto i ngā kukū nui hei kēnoka whaihua mō te tangohanga konumohe, pūkōwhai rānei. Nō reira, kei roto i ngā rāngai pūtaiao me te mātauranga tōna whaihua matua. Ki ngā kaimātai whenua me ngā kaimātai kōhuke, he tohu nui a Prosopite mō te mārama ki te panoni waiariki o te cryolite me te kukuwhatanga matū o ngā pegmatite kiripaka. Ko te uara o te kōhuke ’ e tino whakatauhia ana e tōna onge me tōna tūranga ki te tuhi i ngā tukanga ā-papa motuhake. Nō reira, ahakoa ka taea te hanga me te whakakoi mō ngā kaupapa ātaahua, ka noho tonu hei kōhuke e whai take ana ki ngā kairangahau me ngā kaingākau kōhuke onge, kaua hei rauemi mō te ahumahi papatipu-mākete, mō ngā whakapaipai rānei.
Te Wehewehe i a Prosopite me te Turiki
Hei wehewehe tika i te Prosopite me te Turquoise, me timata ki te whakamatau i to raua pakeke. Ahakoa he rite te ahua, he ngohe ake te Prosopite, he iti noa iho tona pakeke Mohs ki te 4.0 ki te 4.5, na reira ka ngawari te wiri e te whao maitai. Engari, he pakeke ake te Turquoise (5.0 ki te 6.0) a ka kaha ki te ātete i aua wiri. Muri iho, whakaarohia to raua taumaha me te kiato; he paku taumaha ake te Prosopite na te mea he kikī ake i te Turquoise. Mo te tautuhi tika, ka whakamahia te whakamātautau taupū whakaata (RI): ko te ine o te Prosopite tata ki te 1.50, he iti rawa atu i te awhe 1.61 ki te 1.65 o te Turquoise. Hei whakamutunga, he rerekē o raua takenga matawhenua; ko te Turquoise te nuinga o te wa ka puta i roto i nga kohinga parahi puia i nga whenua maroke, engari ko te Prosopite tata tonu ka kitea i roto i nga uaua tītaha onge, i te hononga ranei ki te cryolite.
