Ko te Anghesiti he tuunga motuhake i roto i te rangatiratanga o nga kohuke, he mea whakapaipai a te kaikohi e hono ana i te waenganui o te kohuke ahumahi me te ataahua o te rangi. He kohuke waikawa matā tuarua e hangaia ana i roto i nga rohe whakawera o nga putunga matā, e whakanuia ana e nga tohunga mahi kohatu mo te toronga onge o nga ahuatanga tinana: te kanapa o te taimana, te taumaha nui, me te mura (whakamararatanga) e taea te whakataurite ki te taimana. Ahakoa tona hanganga matū e whakawhiwhia ana ki a ia he taumaha me te mahi whatu kanapa, na taua ahuatanga matā-kaha e tino whakaraerae ai te kohatu. No reira, ahakoa ka tapahia etahi tioata maamaa hei kohatu whakamiharo, ka noho tonu a Anglesite hei taonga mo te whakaaturanga, kaua mo te pouaka whakapaipai—he tikanga kanapa o te kaha me te whakaraerae o te taiao.
Ngā Pūtakenga Ā-Āhuwhenua me te Hanganga
Anglesite he kohuke tuarua te nuinga, ko te tikanga kāore e whakapaketanga tika mai i te toka whakarewa, i te wai wera rānei. Engari, he hua ia nō te “whakakaha tuarua.” Ka tipu ake mā te pākūkā matū me te whakamākūkū o ngā kohuke matua o te pākō tetu, ko te galena te mea tino rongonui.
Inā kitea te galena ki ngā wai meteoric whai hāora (te ua) i ngā wāhi whakarunga, kua whai hāora o ngā putunga maina, ka puta he tauhohenga matū e whakakapia ai te whanariki i roto i te galena e te pākawa whanariki. He maha ngā wā ka puta tēnei panonitanga i te wāhi tonu, i ētahi wā ka puta he "pseudomorphs" e mau tonu ai te āhua tapawhā o te Anglesite i te āhua o te galena i whakakapihia e ia. Ka kitea ēnei putunga i ngā rohe maroke, āhua maroke rānei, he hōhonu te wātai, e taea ai te whakaora nui o te tinana maina.
I te hītori, e whakanui ana te kōhatu’s ingoa i te wāhi taketake: ngā maina parahi o Parys Mountain i te Moutere o Anglesey, i Wales. Heoi, ko ngā tioata tino nui o te kounga karaiti kua kitea mai i te Maina o Tsumeb i Namibia me te rohe o Touissit i Morocco, i reira ngā āhuatanga whenua i taea ai te tipu o ngā tioata nui, mārama, me te rironga tika o te hanganga.
Te Papatae o Anglesite: Mai i te Māramatanga Ā-Wairua ki ngā Tae Whenua
Ahakoa ko ngā tauira tino rongonui o Anglesite ko ērā o te māramatanga parakore, kore tae, engari ka puta te kohuke nei i roto i te whānuitanga o ngā tae e mīharo ana. Ko ēnei rerekētanga te tikanga he hua nō ngā parakore whai tohu, nō ngā whakaurunga iti rānei o ētahi atu kohuke i mau i te wā o te tukanga whakawhāiti.
Tae Kore me te Mā The “tino parakore” āhua o Anglesite he kore tae. I tōna āhua māramarama, whatuwhai, ka pōhēhētia he taimana nā te nui o tana tohatoha. Ina puta mai i ngā āhua nui, kirikiri iti rānei, ka puta mai he mā waiū, he mā pōuri rānei.
Kōwhai kōura me te āpora: I roto i ngā kaikohi, ko ngā momo tae honi mahana, tae atu ki te remana kōwhai ora, e rapua nuitia ana. Ko ēnei tae kōura e kīia ana nā ngā wāhi iti o te waikura rino, o ētahi atu parakore whakarewa rānei i uru mai i te tinana o te kōpura e karapoti ana i te wā o te hanganga.
Kikorangi Mā me Kākāriki: Ko ētahi o ngā momo tino onge, tino whakamiharo ko ngā kikorangi ngāwari me ngā kākāriki māeneene. Ko ēnei tae i te nuinga o te wā ka puta mai i ngā tohu iti o te parahi (he mea tango mai i ngā kōhatu tata pēnei i te malachite me te azurite) kua whakaurua ki roto i te whārangi tioata.
Hina me Pango: I te nuinga o ngā wāhi keri, ka puta mai te Anglesite i ngā tae mākūkū, pōuriuri ake. Ko ēnei tauira he mea “pekapeka” e ngā whakaurunga moroiti o te galena kāore anō kia waikuratia, e hōmiromiro ana i te kiripaka ki te kōriori hiriwa, ki te pango-waru rānei hei whakapoururu o roto.
Paurauri me te Karaka Ka kitea ngā kohatu hōhonu parauri-karaka, e kīia ana he “cognac”, inā rawa i ngā pūtotanga o Moroccan. Ko ēnei tae whenua e whakarato ana i tētahi tūāpapa whakaute mō te kanapa matahiwa nui o te kohuke.
He pai a Anglesite mō ngā whakapaipai?
Ahakoa he tīaho me te ahi e taea te whakatairite ki te taimana, kāore e kitea nuitia te Anglesite i roto i ngā whakapaipai auraki. Ko tōna korenga i te mākete arumoni, nā tōna tino whakaraerae tinana. He 2.5 ki te 3.0 anake te pakeke o te Mohs, he ngawari te kōhatu kia waruhia e te pene parahi, ahakoa e te maikuku anō hoki. I tua atu, na tōna tino wehenga me tōna āhua pakarukaru, ka tino pāpōuri ki te whati i te wā e mahia ana, i raro rānei i ngā taumahatanga o te mau o ia rā. I tua atu i tōna whakaraerae, ko te nui o te konupūmā i roto i te kohuke—e tata ana ki te 70%—he mōrearea paitini ki te horomia te puehu i te wā e tapahia ana, ki te mau rānei ki te kiri mō te wā roa. Nā reira, ko te Anglesite kua whakapīramiti, e kiia ana he "kōhatu whakahaumanu a te kaikohi," he mea whakaatu me te rangahau, kaua hei whakapaipai mahi.
Ngā Āhuatanga o te Mākete me te Tononga Kaikohi
Ko te Anglesite he waahi motuhake i roto i te mākete o nga kohuke me nga kohatu whakapaipai a te kaikohikohi, kaua ki te hokohoko whakapaipai auraki, a, ko tona uara e whakatauhia ana e te kounga o nga tioata, te ataahua, te totika o te hanganga, me te mana o te rohe, kaua e nga punaha whakatau uara arumoni. Na te iti o tona pakeke (2.5–3 i runga i te tauine Mohs), te tino wehenga, me te pakarukaru, he uaua te hanga mata, a, kare i te noa te tapahi whai hua nui; na reira, ko te nuinga o nga kohatu mata ma te iti o te 3–4 karati e hokona ana i roto i te awhe iti o te kaikohikohi, tata ki te $30 ki te $150 mo ia karati, i runga i te marama, te tae, me te takenga mai, engari ko nga tauira nui ake i te 4 karati, ka nui ake te utu—engari e whakawhirinaki tonu ana ki te rohe—i roto i te mākete iti motuhake. Heoi, mo te nuinga o nga kaikohikohi, he pai ake nga tauira tioata maori i nga kohatu tapahi, ina koa nga tioata pai te hanga e whakaatuhia ana i runga i nga matua rereke penei i te Galena, kei reira te ataahua me te ahua e kaha awe ana i te uara. Ko nga tauira mai i nga waahi whai mana o mua, ina koa te Tsumeb Mine me te Touissit, he maha nga wa e utaina ana he taapiri rohe; ko nga wahanga o te kounga whare taonga mai i enei puna ka hokona pea i roto i te awhe tata ki te $500 ki te $2,500 neke atu ranei, i runga i te rahi o te tioata, te marama, te tae, me te totika o te tauira katoa. Ahakoa te onge o te ahua kounga-kohatu, me whakaaro ko te Anglesite he kohuke kaikohikohi o te hiahia ataahua me te pūtaiao, kaua hei kohatu whakapaipai whakangao tikanga, na te mea he iti, he motuhake tana mākete, a, e akiakihia ana e te hiahia o te tohunga, kaua e te whakapae putea whanui.
Ngā Tikanga Tautuhi me ngā Tikanga Whakatau Mate
Nā te mea ka raruraru te Anglesite ki ētahi atu kohatu tīpako mōriki pērā i te Cerussite, te Phosgenite, me te Taimana anō hoki, ka whakawhirinaki ngā tohunga kohatu ki te whakakotahitanga o ngā whakamātautau ā-tinana me ā-whatu:
Tino Kiato Ko tētahi o ngā tohu tino kitea ko tōna taumaha motuhake. I te 6.3 tata, he taumaha kē atu i te mea e tika ana mō tōna rahi. I roto i te whare taiwhanga, mā te pauna waihā e wehewawe i a ia i ngā āhua rite māmā ake.
Kānapanapa me te Mararatanga: I raro i te karu a te kaihoko rei, ka whakaatu a Anglesite i te kanapa “adamantine” (pērā i te taimana). Ko tōna mararatanga—te kaha ki te wehe i te mārama mā ki ngā tae tuāwhiorangi—he 0.044. Ahakoa he tata ōrite tēnei ki te taimana, nā te iti rawa o te pakeke o Anglesite e māmā ai te wehewehe i raro i te whakanikoniko mā te rapu i ngā hononga mata porotaka, i ngā waro mata rānei.
Taupū Whakaata: Ko te Anglesite he taupītanga whakaata e rere ana i te 1.87 ki te 1.89. Ko tēnei te “kei runga ake i te rohe” (OTL) mō te refractometer paerewa, e hiahia ana i ngā taputapu matatau pēnei i te reflectometer, i ngā tikanga rumaki rānei hei ine tika.
Kōwhititanga Hīhī Tāpokopoko: He maha ngā tauira e whakaatu ana i tētahi pūngorongoro motuhake. I raro i te rama UV ngaru-poto, ka whiti te Anglesite he kōwhai kārikī, he kōwhai-koura rānei, ka taea e tēnei te āwhina ki te wehewehe i a ia mai i ētahi atu kohuke mātā i tētahi āhua taratara.
Whakamātautau Waikawa: Hei pākawa, he pōturi te memehatanga o Anglesite i roto i ngā waikawa kukū, ahakoa he whakamātautau whakangaro tēnei, ā, kāore e mahia nuitia ki ngā kohatu tapahia.
I roto i te whāriki nui o te rangatiratanga kohuke, ko Anglesite te tohu o te meka e kore e rite te kanapa ki te kaha i ngā wā katoa. He kohuke e tono whakaute ana, ehara i te mea mō tōna haerenga ā-papa mai i te pōhā pango ki te kiripaka mārama, engari anō hoki mō te tiaki motuhake e hiahiatia ana hei tiaki i tōna “ātaahua ahurei”. Mō te kaikohi whakapau kaha, ko te whai i tētahi Anglesite pai—ahakoa he kāhui kikorangi Tsumeb, he kohatu whakairo whakamararatanga tiketike rānei—he nui ake i te uara mākete. Ko te tikanga he tiaki i tētahi “rīrā kanapa”: he kohatu e hopu ana i te marama me te kaha o te taimana, engari he wairua ngāwari pēnei i te rau maroke. Ahakoa kāore e kitea he kāinga i roto i te pouaka whakapaipai noa, ko tōna wāhi i roto i ngā whakaaturanga o ngā whare taonga pai rawa o te ao me ngā kohinga tūmataiti kua mau tonu hei tētahi o ngā mahi toi tino pīataata, ahakoa he whakaraerae, a te taiao.
