I-Zircon iyiminerali eqinile ngamakhemikhali ebalulekile ekulandeleni i-granite petrogenesis ngenxa yekhono layo lokugcina ulwazi oluyisisekelo lwe-magmatic ngesikhathi sokuguqulwa kwe-metamorphism kanye nokuguqulwa kwe-high-grade. Kuma-granite ane-silica ephezulu, izilinganiso ze-zircon element (isb., Zr/Hf, Eu/Eu*, Ce/Ce*) ishadi lokuhlukaniswa nokuqongelela kwe-crystal-melt, okuhlukanisa izindawo ze-granite ezihlanganisiwe ze-zircon content ephezulu ezizindeni ezincibilikisiwe. Lesi sixazululo se-geochemical sisekela amamodeli e-granite mineralization, okuthuthukisa ukuqondiswa kwezinsiza kuma-granite ane-zircon.

Izindlela Zokunquma Ukuhlushwa kweZircon kuGranite
Ukulinganiswa kokuhlushwa kwe-zircon ku-granite kuqala ngokuhlukaniswa koketshezi okunzima, ngokuvamile kusetshenziswa i-methylene iodide, ehlukanisa amakristalu e-zircon. Ukubala nokukala lezi zinhlamvu kuveza ubuningi be-zircon obusekelwe kubuningi, kodwa ukuqina kwabasebenzi kanye nokubhujiswa kwamasampula kuyizinkinga ezinkulu. Izindlela ezingezona ezonakalisayo, njenge-X-ray fluorescence (XRF), zihlaziya amasampula e-granitic aqinile ngaphandle kokuncibilika kwamakhemikhali.
Izisekelo ze-X-Ray Fluorescence (XRF) ekuHlaziyweni kwezimbiwa
I-XRF isebenza ngama-athomu ajabulisayo ku-granite, okubangela i-emission spectra ngokulingana nobuningi bezinto eziyisisekelo. I-Lonnmeter XRF analyzer ithola i-Zr, ihlukanisa i-zircon kwamanye amaminerali e-granite ngokuqukethwe kwayo okuhlukile kwe-Zr. I-XRF ilinganisa izakhi eziningi emadwaleni e-granite ngemizuzwana, isekela ukuhlolwa okusheshayo kwensimu ye-granite ephezulu ye-zircon. Ukulungiswa kwesampula kuncane; ama-slabs aqinile noma ama-powder anele. Ithuluzi libika amazinga e-Zr aqondile, okuvumela ukuhlonza okusheshayo kwe-granite nge-zircon. Ngokungafani nokuncibilika kwamakhemikhali, i-XRF igcina ubuqotho besampula, inciphisa ingozi yokungcola. I-Zr ephakanyisiwe yi-XRF ivame ukuxilonga amazinga e-zircon amaminerali ku-granite, yize izindlela ezengeziwe zidingeka ukuze kubalwe okusanhlamvu okuphelele.
Ukuqhathaniswa kwesikhathi, ukulungiselela isampula, kanye nezinzuzo zokuhlaziya ezingonakalisi ze-XRF ngokumelene namasu okuhlukaniswa kwendabuko kanye nokuhlaziywa okuncane kwe-zircon ekwakhekeni kwe-granite.
I-Lonnmeter XRF Analyzer: Isixazululo Esithuthukisiwe se-ZirconSori-ting
I-Lonnmeter XRF ifinyelela ukuzwela okuphezulu kwe-zirconium, ithola okuphansi njenge-10 ppm Zr kuma-granite matrices ajwayelekile. Isikhathi sokulinganisa silinganiselwa ngaphansi kwemizuzwana engama-60 ngesampula ngayinye. I-interface yayo yesofthiwe ivumela ukusebenza okusheshayo, ukuthunyelwa kwedatha ye-batch, kanye nokuqhathaniswa okuzenzakalelayo kwe-spectral kokuhlushwa kwe-zircon ku-granite. I-chassis eqinile, eqinile (1.5 kg) isekela ukuthunyelwa kokubili emikhankasweni yokumapha insimu kanye namalabhorethri ajwayelekile e-petrology. Le yunithi isekela ukuskenwa okuqondile kwamasampula esandla noma ama-pellets e-powder acindezelwe, okususa isidingo sokusebenza okubanzi kokulungiselela amasampula.
Amakhono Obuchwepheshe Bokuhlaziywa kweZircon
I-Lonnmeter XRF isebenzisa izitholi zokuvusa ezilungiselelwe kahle kanye nezitholi zokukhukhuleka kwe-silicon ukuze kulinganiswe kahle i-Zr. Amaphrothokholi okulinganisa ahambisana ne-matrix afanele okuqukethwe kwe-silica, ukuphazamiseka kwe-Fe, kanye ne-Ca, okuqinisekisa ukufundwa okunembile ngisho nasemadwaleni e-alkali feldspar acebile, ane-silica ephezulu. I-analyzer ifaka ama-algorithms okulungisa akhelwe ngaphakathi emiphumela ye-granite matrix futhi inikeza izindlela zokumisa ezizenzakalelayo zokulinganisa njalo i-granite ene-zircon kanye namaminerali e-granite axubile anamakristalu e-zircon.
Ukuthuthukiswa Kokuhamba Komsebenzi Kwezinhlolovo Ze-Geological
Ukusampula kusheshiswa ngamalebula anebhakhodi kanye nokufakwa kwe-geodata okufakwe i-GPS. I-Lonnmeter XRF ihlanganisa ukuthunyelwa ngqo kwamaphrofayili aphelele (kufaka phakathi i-Zr) ukuze kuhlolwe imephu ye-geostatistical kanye nokuhlaziywa kwezithombe ezinobuningi. Ukuhamba komsebenzi kwedijithali kuhlangana kalula nezizindalwazi ze-petroli kanye nama-suite okumodela e-geochemical. Amamojula okuhlaziya izithombe abalwa futhi adwebe amakristalu e-zircon ku-granite ngokuhlobanisa izindawo ezishisayo ze-Zr; ama-algorithms aqondisiwe alungisa ukuhlukaniswa kwama-granite anokuqukethwe okuphezulu kwe-zircon. Idatha ilethwa ngamafomethi ajwayelekile, okuvumela ukuhlanganiswa okuqondile emisebenzini yezinqumo zephrojekthi ukuze kusetshenziswe i-granite esebenza kahle ngemephu ye-zircon kanye nokuhlolwa kwezimbiwa.
Ukuthuthukisa Izifundo Zokuhlola Nokubhekisisa Izinsimbi
Izilinganiso zezinto eziyisisekelo—i-Zr/Hf, i-Zr/Y, kanye ne-Zr/Ti—ezitholakala nge-Lonnmeter XRF zinikeza ukujiya okusheshayo, endaweni ethile ezindaweni ze-granite ezinamaminerali. Ukuhlushwa okuphezulu kwamaminerali e-zircon kuhambisana neziginesha ezihambisana ne-ore ezinhlelweni ze-Mo-W kanye ne-Sn-W ezingavamile, njengoba kubhaliwe ezinhlolovo ze-granite ezinkulu. Ukulinganiswa okuzenzakalelayo kusheshisa ukuhlonza amathuba e-ore ensimini, okubalulekile ekuhlolweni kwe-granite engavamile.

Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa)
Kungani kufanele ukhethe i-X-ray fluorescence (XRF) yokuhlaziya ukuhlushwa kwe-zircon ku-granite?
I-XRF ilinganisa i-zirconium, isakhi esiyinhloko se-zircon, ngokushesha nangokungabhubhisi kumasampula e-granite aqinile. Le ndlela iqeda izinyathelo zokuhlakazeka kwesampula ezidinga umsebenzi omkhulu noma zokuhlukanisa amaminerali. I-XRF ithola ngasikhathi sinye izinto eziningi ezinomkhawulo wokuthola i-zirconium ophansi njenge-1-5 ppm kuma-matrices e-granite ayinkimbinkimbi, isekela imephu evamile kanye nokuhlolwa kwezinsiza ze-granite ephethe i-zircon kanye ne-granite enokuqukethwe okuphezulu kwe-zircon.
Ingabe i-XRF ingahlukanisa i-zircon kwamanye amaminerali asindayo ku-granite?
I-XRF ilinganisa ngqo okuqukethwe yi-zirconium, okuhlonza ngokukhethekile i-zircon kumaminerali e-granite. Amanye amaminerali asindayo awavamile ukuqukatha i-zirconium ebalulekile, ngakho-ke ukubala ubuningi be-Zr kuhambisana nokuhlushwa kwamaminerali e-zircon. Le ndlela iyasebenza ekuhloleni i-granite nge-zircon kanye nokuhlukanisa phakathi kwamaminerali e-granite ane-zircon kanye nalawo angenayo.
Yiluphi ulwazi olunganikezwa yi-XRF ukuhlaziywa kwe-zircon ku-granite ekuhlolweni kwamaminerali?
I-XRF inikeza ukugcwala kwe-zirconium kanye nezilinganiso ezibalulekile ze-trace element (isb., Zr/Hf, Th/U) endaweni yokuhlola umthombo wokuncibilika kwe-granite, ukuzala, kanye nezindlela zokwakheka kwekristalu. Le datha ivumela izazi ze-geology ukuthi zihlukanise i-granite enokuqukethwe okuphezulu kwe-zircon, i-vector maqondana nemizimba ye-granite ehlobene ne-ore, futhi zithuthukise ukuqondiswa kwamadiphozithi ensimbi engavamile kanye ne-base-metal.
