Ko te Adularia he momo pākāriki pūmāota ki te mārama, he momo orthoclase i hanga i te pāmahana iti. Ahakoa he rite tōna hanganga matū ki ētahi atu pākāriki noa, e whakaaturia ana e te tātai KAlSi₃O₈, ka wehewehea e tōna āhua tioata motuhake me tōna taiao whakapūmau. E mōhiotia ana mō tōna āhua kore tae ki te mā-kirakira me te kanapa karaihe, ka puta te adularia i ngā āhua pseudo-orthorhombic e wehe ai i a ia i ētahi atu kohuke o te rōpū orthoclase. I te ao kōhatu utu nui, ko te adularia kounga teitei te kohuke matua e whakaputa ana i te āhuatanga kōhatu marama. Ko tēnei āhuatanga, e kīia ana ko te adularescence, ka puta ina marara te marama i waenga i ngā paparanga moroiti o te tioata, e hanga ana i te kanapa kikorangi, mā rānei e rere ana i te mata o te kōhatu.
Ko te hanganga o te adularia ka puta i roto i ngā taiao waiariki iti, he rerekē i te nuinga o ngā feldspar e whakaputa ana i te magma puia wera nui. Ka kitea nuitia i roto i ngā kapiti puke-momo me ngā uaua epithermal, i reira ka whakaheke mai i ngā wai kohuke-whai rawa i ngā pāmahana i waenga i te 200°C me te 300°C. I te whakamatao o ēnei wai pāhare pāporo i roto i ngā kōhao toka, ka tere te tipu o ngā tioata adularia, ka puta he hanganga ngota e tika ake ana i tōna whanaunga pāmahana teitei, a sanidine. Nā tēnei ara whanaketanga motuhake, ka kitea te adularia i te taha o ngā kohuke pēnei i te quartz, te chlorite, me te hematite, hei tohu matua mō ngā kaimātai whenua e rangahau ana i te hītori waiariki me te matū wai o ētahi pae maunga me ngā putunga kohuke.
I rohe hītori, he wāhi nui te adularia ki te whanaketanga o te pūtaiao kōhatu. I whakaingoatia ōkawatia te kōhatu i te tau 1783 e te kaipūtaiao Itari a Ermenegildo Pini, nāna i tiki te kupu mai i te Rōpū Adula o ngā Maunga Alpine Waenga i Switzerland. Ko te rohe o St. Gotthard i ēnei maunga te wāhi i puta ai ngā tauira tuatahi e mōhiotia whānuitia ana, i whakanuia mō tō rātou māramatanga tino pai. I ngā rautau 18 me 19, ko te adularia te pūtake o ngā tautohetohe pūtaiao mō te whakarōpūtanga o ngā silicates, nā te mea ko tōna māramatanga rite-ki-te-wai i hē ai te tautuhi a ngā kaikohi tuatahi hei quartz. I tua atu i tōna uara pūtaiao, kua roa te adularia e whakanuia ana hei kōhatu whakapaipai mō ngā mano tau. I hono ngā iwi tawhito i ōna pānga kanapa ki ngā wahanga o te marama, i puta ai tōna whakamahinga whānui ki ngā whakapaipai me ngā taimana puta noa i ngā ahurea maha, i reira i whakaponohia ai he whakamarumaru me te māramatanga wairua ki te kaimau.
Te whakamōhiotanga i a Adularia mai i ētahi atu Feldspars
Ko te Adularia e wehewehea ana i ētahi atu mema o te rōpū feldspar mā te āhua o tōna hanganga me te pāmahana o te whakapūmau. Kāore i rite ki te orthoclase noa, ki te sanidine rānei, e whakapūmauria ana i te nuinga o te wā mai i te whakarewa ahi pāmahana teitei, ka whakapūmauria te adularia i roto i ngā taiao waiariki pāmahana iti. Nā tēnei tukanga tipu motuhake ka puta he whakaritenga ngota "ōta" ake, me tētahi āhua karaihe ahurei e mōhiotia ana hei poraka ngāwari, āhua taimana, āhua-orthorhombic rānei.
Ahakoa he ōrite te tātai matū KAlSi₃O₈ ki ētahi atu pākūkū pāhare o te pāhare, ko tōna māramatanga teitei me te kore o ngā tae kōwhai, māwhero rānei e whakaaweawe ana i te rino, e kitea whānuitia ana i roto i te maha o ngā tauira orthoclase, ka tino rerekē te āhua. I tua atu, ko te adularia anake te momo pākūkū e whakaatu tonu ana i te adularescence pono—te marara o te mārama i roto e hanga ana i te kanapa kikorangi, mā rānei e rewa ana—i te mea ko ētahi atu pākūkū pērā i te labradorite, te amazonite rānei, e whakaatu ana i ngā āhuatanga whatu rerekē, pērā i te labradorescence, te schiller māmā rānei, nā ngā whakaurunga kōhatu rerekē me ngā tauira whakawhiti mārama.
Ngā Whakamahinga o te Adularia
Ko te Adularia, he momo orthoclase feldspar kore tae ki te mārama, e whakamahia ana mō ngā kaupapa maha mai i ngā whakapaipai utu nui ki ngā rangahau ārai whenua whakahirahira. Ko tāna whakamahinga tino rongonui kei te ao kōhatu utu nui, e mōhiotia ana ko te wāhanga matua o te Moonstone. Nā tōna hanganga ā-roto ahurei, e whakaatu ana i tētahi āhuatanga whatu whakamīharo e kīia nei ko te adularescence—he rama kikokiko, kanapa kikorangi, mā rānei e kōpeke ana i te mata o te kōhatu. Nā tēnei āhuatanga ātaahua, he tino pai mō ngā tohunga mahi toi e hanga ana i ngā mōwhiti cabochon, ngā tahei, me ngā whakairo whakapaipai, e hono ana ki ngā kaupapa o te māramatanga me te taurite i roto i ngā ahurea maha.
Ko Adularia he mana nui i roto i te ao o te geochronology. Nā te mea he nui te pāhare o te konupā i roto, he tino pai mō te whakamātau Ar-Ar. Ka whakamahia e ngā kaimātai whenua ēnei tioata ki te tautohu i te wā tika o ngā mahi waiariki, e taea ai e rātou te whakahou i te hītori whakamahana o te kirinuku o te whenua me te whakatau i te wā i hanga ai ētahi pae maunga, ētahi uaua kohuke rānei. Ka toro tēnei whaihua pūtaiao ki te ahumahi maina; e kiia ana ko Adularia he kohuke kaiārahi. Ko tōna noho i roto i ngā hanganga toka he tohu mō te hītori o te whakapūkohu o ngā wai waiariki, he tohu matua mō te kimi i ngā putunga koura me te hiriwa epithermal o te taumata tiketike.
I roto i te horopaki ahumahi, ka whai wāhi te adularia ki te hanga uku me te karaihe. Ahakoa e whakamahia nuitia ana te feldspar noa iho nā te nui o te wātea, nā te nui o te pāhare pāporo o te adularia ka waiho hei kaihoko whakarewa pai rawa atu. Ina tāpirihia ki ngā pōkai uku, ka āwhina ki te whakaheke i te pāmahana whakarewa o te ranunga, e whakatairanga ana i te tukanga whakapūtoi e hōmiromiro ai te uku me te mārama. Ahakoa e whakamahia ana hei whakatau i te nekehanga o ngā papa tectonic, hei hopu rānei i te mārama i roto i tētahi wāhanga whakapaipai pai, ka noho tonu te adularia hei kohuke tino nui ki ngā pūtaiao me ngā kaikohi hoki.
