I-Pyrite: Igolide Lobuwula Le-Geology

I-Pyrite, eyaziwa nangokuthi igolide lesiwula, iyiminerali ye-sulfide evamile etholakala ezindaweni ezihlukahlukene ze-geological. Inombala ohlukile wethusi-ophuzi kanye nokucwebezela kwensimbi, okuholele esiteketisoni sayo. Nakuba ingase ifane negolide esweni elingaqeqeshiwe, i-pyrite empeleni ihluke kakhulu ngokwezakhiwo zayo ezingokomzimba namakhemikhali.

I-pyrite inesakhiwo se-cubic crystal, ne-molecule ngayinye eyakhiwe ama-athomu ensimbi nesibabule ahlelwe ngendlela ethile. Ngokuvamile kutholakala ngesimo samakristalu amancane, akheke kahle, nakuba kungenzeka futhi njengama-aggregates amakhulu, ama-granular.

I-Pyrite itholakala ezindaweni eziningi ezihlukene ze-geological, okuhlanganisa amatshe e-sedimentary, amadwala e-metamorphic, kanye ne-hydrothermal deposits. Ivame ukuhlotshaniswa namanye amaminerali afana asebenza ngebhethri, i-calcite, ne-galena.

Esinye sezici ezihluke kakhulu ze-pyrite ubulukhuni bayo. Esikalini se-Mohs, esisetshenziselwa ukukala ubulukhuni bamaminerali, i-pyrite iwela ku-6.5, ethambile kancane kune-quartz kodwa eqine kakhulu kune-talc. Lokhu kwenza kube lula ukuklwebha ngommese or enye into ebukhali, kodwa kunzima ukuyichoboza noma ukuyihlikihla.

Ngokwendawo, i-pyrite ingatholakala emhlabeni wonke, nakuba ivame kakhulu ezindaweni ezithile. Ivamise ukutholakala kumadiphozithi amakhulu ezindaweni ezifana neNingizimu Melika, iSpain, neChina. Kwe I-united states, ivame ukutholakala eziNtabeni Zase-Appalachian nasezifundeni ezisentshonalanga, ikakhulukazi e- Nevada futhi Colorado.

Enye yezinto ezibaluleke kakhulu ukusetshenziswa kwe-pyrite njengensimbi yensimbi. Insimbi iyisici esibalulekile ekukhiqizeni insimbi, futhi i-pyrite iwumthombo obalulekile wale nsimbi. Ngaphezu kokusetshenziswa kwayo embonini yensimbi, i-pyrite iphinde isetshenziswe njengomthombo wesulfure futhi njenge-catalyst embonini yamakhemikhali.

I-Pyrite nayo ingumdlali obalulekile ku- ukuqeqeshwa we-acid mine drainage, okuyinkinga enkulu yezemvelo ezindaweni eziningi zomhlaba. Lapho i-pyrite ivezwa emoyeni nasemanzini, isabela ukuze yenze i-sulfuric acid, engakhipha izinsimbi ezisindayo nobunye ubuthi edwaleni nasenhlabathini ezungezile. Lokhu kungangcolisa amanzi futhi kudale umonakalo omkhulu endaweni.

Naphezu kwemithelela yayo engemihle kwezemvelo, i-pyrite isalokhu iyimineral ebalulekile embonini yokwakheka komhlaba nezimayini. Izakhiwo zayo eziyingqayizivele kanye nokwenzeka kwayo okusabalele kuyenza ibe umthombo obalulekile okungenzeka uzoqhubeka nokuxhashazwa iminyaka eminingi ezayo.
