I-Aragonite iyiminerali ye-carbonate eyingqayizivele enezakhiwo ezihlukahlukene ezithakazelisayo nezehlakalo emhlabeni we-geologic. Nakuba kungase kungaziwa njengabanye abalingani bayo bamaminerali, njenge-calcite ne-dolomite, i-aragonite iyimaminerali ebalulekile okufanele ihlolwe ngokujula okukhulu. Kulesi sihloko, sizohlinzeka ngomhlahlandlela ophelele we-aragonite, ohlanganisa yonke into kusuka kuyo isakhiwo sekristalu kanye nezakhiwo ezibonakalayo ekuveleni kwayo nasekusetshenzisweni kwayo emhlabeni wokwakheka komhlaba.
Okokuqala, ake siqale ngezisekelo. I-Aragonite iwuhlobo lwe-calcium carbonate mineral, okusho ukuthi yakhiwa ama-athomu e-calcium, i-carbon, ne-oxygen. Inohlelo lwekristalu elingunxantathu futhi imvamisa yakha ngesimo samakristalu amade, afana nenaliti. Lawa makristalu angatholakala ngemibala ehlukahlukene, kufaka phakathi omhlophe, ompunga, ophuzi, futhi onsundu, futhi kwesinye isikhathi angaba nokukhanya obala. or ukubukeka okukhanyayo.
Enye yezinto ezithakazelisayo kakhulu ze-aragonite ukuthi ingaba khona ezinhlakeni ezimbili ze-crystal ezihlukene, kuye ngokuthi izimo ezakha ngaphansi kwazo. Isakhiwo sokuqala sibizwa ngokuthi i-orthorhombic form, okuyindlela ezinzile futhi evamile ye-aragonite. Isakhiwo sesibili sibizwa ngokuthi ifomu le-monoclinic, elingazinzile futhi lenzeka kuphela ngaphansi kwezimo ezithile.
Ngokuphathelene nezakhiwo zayo ezingokomzimba, i-aragonite iyiminerali ethambile uma kuqhathaniswa, enobunzima be-Mohs obungu-3.5 kuya ku-4. Inesisindo esithile esisuka ku-2.9 kuya ku-3.0 futhi ayiminyene kakhulu, okwenza kube lula ukunwaya ngozipho noma ngento ebukhali. . Iphinde ibe brittle futhi ingaphuka kalula noma iphihlike uma ingaphansi kwengcindezi noma ingcindezi.
I-Aragonite ivame ukutholakala ezindaweni ezihlukahlukene ze-geological, kufaka phakathi ukwakheka kwemigede, izixhobo zamakhorali, namadwala e-metamorphic. Ivame ukutholakala ngokuhlangana namanye amaminerali e-carbonate, njenge-calcite ne-dolomite, futhi ingaba yingxenye ebalulekile yamadwala e-sedimentary njenge-limestone ne-marble.
Esinye sezenzakalo ezidume kakhulu ze-aragonite kusemigedeni. Lapho amanzi aqukethe i-calcium carbonate namanye amaminerali ancibilikisiwe egeleza emhumeni, angabeka lawa mamineral ezindongeni nophahla lomhume, enze amaphethini amahle nayinkimbinkimbi. Lawa maphethini abizwa ngokuthi ama-speleothems, futhi angathatha uhlobo lwama-stalactites (alenga ophahleni), ama-stalagmites (akhula kusukela phansi), nokunye ukwakheka. I-Aragonite ivame ukuba ingxenye enkulu ye-speleothems, kanye ne-calcite namanye amaminerali.
Esinye isenzakalo esibalulekile se-aragonite sisezixhobo zamakhorali. Izixhobo zamakhorali zakhiwa izilwane ezincane ezimise okweshubhu ezibizwa ngokuthi ama-coral polyps, ezikhiqiza uhlaka lwamathambo e-calcium carbonate emizimbeni yazo. Njengoba la mathambo enqwabelana ngokuhamba kwesikhathi, akha ukwakheka kwe-coral reef. I-Aragonite iyingxenye enkulu yalezi zinhlaka zamakhorali, kanye ne-calcite namanye amaminerali.
Ngaphezu kokuvela kwayo ekwakhekeni kwemigede kanye nezixhobo zamakhorali, i-aragonite ingatholakala futhi emadwaleni e-metamorphic, njengemabula. I-Marble iyidwala le-metamorphic elakheka lapho i-limestone noma amanye amatshe e-sedimentary engaphansi kokucindezela okukhulu kanye namazinga okushisa, okwenza amaminerali aphinde ahlangane abe yifomu elisha, elizinzile. I-Aragonite ivame ukuba khona emabula, kanye ne-calcite namanye amaminerali.
Mayelana nokusetshenziswa kwayo, i-aragonite ayibalulekile noma isetshenziswa kabanzi njengamanye amaminerali, njenge asebenza ngebhethri noma idayimane. Nokho, inazo ezinye izinhlelo zokusebenza ezibalulekile zezimboni. Isibonelo, isetshenziselwa ukukhiqizwa kukasimende, okuyingxenye ebalulekile yezinto eziningi zokwakha. Isetshenziswa futhi ku
ukukhiqizwa kwe-lime yezolimo, esetshenziselwa ukunciphisa i-pH yomhlabathi nokwenza ngcono ukuvunda komhlabathi. Ngaphezu kwalokho, i-aragonite isetshenziswa njengokugcwalisa emikhiqizweni ehlukahlukene, njengamapulasitiki, amapende, nerabha.
I-Aragonite nayo iyaziswa ngobuhle bayo nokungatholakali kwayo, futhi ngezinye izikhathi isetshenziswa njengetshe eliyigugu noma isici sokuhlobisa ubucwebe nezinye izinto zokuhlobisa. Ivamise ukusetshenziswa ekuhlanganisweni namanye amaminerali, njenge-quartz noma i-turquoise, ukudala izingcezu eziyingqayizivele nezihehayo.
Kafushane, i-aragonite iyiminerali eyingqayizivele futhi ethakazelisayo okufanele ihlolwe ngokujula okukhulu. Inezinto ezihlukahlukene ezithakazelisayo nezenzeko, futhi inezinhlelo zokusebenza ezibalulekile zezimboni. Kungakhathaliseki ukuthi uyisazi sokuma komhlaba esingumakadebona noma unentshisekelo ezimangalisweni zemvelo zomhlaba, ukufunda okwengeziwe nge-aragonite ngokuqinisekile kuzoba okuhlangenwe nakho okufundisayo nokujabulisayo.
