Isibabule siyikhemikhali enophawu S kanye nenombolo ye-athomu engu-16. Siphuzi ngokugqamile, siqinile esiqinile ekushiseni kwegumbi futhi sinephunga elihlukile, elihlabayo. Isibabule siyisici esibalulekile kusayensi yokwakheka komhlaba nesayensi yomhlaba, futhi sidlala indima ebalulekile ezinhlobonhlobo zezinqubo zokuma komhlaba.

Ku-geology, isulfure itholakala kakhulu ngesimo sama-sulfide, okungamaminerali aqukethe isulfure kanye nenye. or ezinye izakhi. Amanye amaminerali e-sulfide avamile ahlanganisa i-pyrite (iron sulfide), i-chalcopyrite (i-copper-iron sulfide), ne-sphalerite (zinc sulfide). Ama-sulfide angamaminerali abalulekile e-ore futhi avame ukumbiwa izinsimbi eziqukethe.

I-Sulfur iyatholakala futhi ngesimo se-sulphur dioxide (SO2) emkhathini womhlaba. Kunomthelela omkhulu ekungcoleni komoya futhi kungaba nemiphumela engemihle empilweni yomuntu, kodwa futhi kudlala indima ebalulekile esimweni sezulu soMhlaba. I-Sulfur dioxide iyigesi ebamba ukushisa emkhathini, futhi ingaba nomthelela ekushiseni ukuqeqeshwa yamafu nemvula.

Ngaphezu kokuba khona kwaso kuqweqwe lomhlaba nasemkhathini, isulfure nayo iyisici esibalulekile ku-hydrosphere Yomhlaba. Itholakala ezinhlobonhlobo zamakhemikhali ancibilikayo emanzini, njengama-sulfate nama-sulfite, angancibilika emanzini futhi athuthwe ngomjikelezo wamanzi. Isibabule siphinde sibe yingxenye eyinhloko yamanye ama-amino acid, okuyizingqimba zokwakha amaprotheni.

Isibabule sinomlando omude emphakathini wesintu futhi siye sasetshenziselwa izinjongo ezihlukahlukene phakathi namakhulu eminyaka. Isetshenziswe njengenhlanganisela yokwelapha, i-fumigant, kanye ne-preservative. Ibuye isetshenziselwe ukwenza umbala kumapende nakudayi nanjengengxenye yesibhamu.

Enye yezinto ezibaluleke kakhulu ukusetshenziswa kwesibabule ezikhathini zanamuhla ukukhiqizwa kwe-sulfuric acid. I-Sulfuric acid iyi-asidi eqinile esetshenziswa kakhulu embonini yamakhemikhali, futhi iyingxenye ebalulekile yomanyolo, okokuhlanza neminye imikhiqizo.

Ku-geology, isulfure inenani lezinhlelo zokusebenza ezibalulekile. Isetshenziselwa ukukhomba ukuba khona kwamaminerali athile kanye nokunquma ukwakheka kwawo kwamakhemikhali. I-Sulfur isotopes ingasetshenziswa ukutadisha imijikelezo ye-geochemical yomhlaba kanye nokuqonda umlando woMhlaba. Isibabule singasetshenziswa futhi ukunquma iminyaka yamadwala namaminerali ngokusebenzisa inqubo ebizwa ngokuthi i-sulphur-isotope geochronology.

Isibabule siyisici esibalulekile ekucwaningweni kwesayensi yokwakheka komhlaba nesayensi yomhlaba, futhi sidlala indima ebalulekile ezinqubweni eziningi ezibalulekile zokuma komhlaba. Ukuba khona kwawo oqweqweni loMhlaba, emkhathini, naku-hydrosphere kuyenza ibe isici esibalulekile sokuqondwa nokufunda. Kusukela ekusetshenzisweni kwaso ekukhiqizeni i- sulfuric acid kuya endimeni yayo emjikelezweni wesimo sezulu nowomhlaba wamanzi, isibabule siyinto ebalulekile eye yaba nomthelela omkhulu eMhlabeni nasemphakathini wesintu.

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 yiyona ubulukhuni. Esikalini se-Mohs, esisetshenziselwa ukukala ubulukhuni bamaminerali, i-pyrite iwela ku-6.5, ethambile kancane kune-quartz kodwa eqinile 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.
