Amaminerali aseAustralia

Igama linikezwe kweli zwekazi ukusuka kwisiLatini. Kulo igama elithi "ngasentla" lithetha kunye negama le-Australia. Kwaye oku akukhawulezi, kuba liphela ngokupheleleyo kwinxalenye yehlabathi. Ngokommandla wonke ohlala kuyo (kwaye oku malunga neekhilomitha ezili-7.6 zeekhilomitha ezili-1,6), i-Ostraliya ibhekwa ngokufanelekileyo njengelizwekazi elincinane kunazo zonke emhlabeni wethu. Ngenxa yalesi sizathu, abanye abaphengululi bavame ukuyijonga kwiziqithi ezisemaphandleni. Uninzi lwamanxweme luhlanjululwa ngamanzi anosawoti oLwandle lwaseNdiya kwaye kuphela ukusuka kwelinye, icala elimpuma - yi-Pacific Ocean.

Ihlabathi likude kakhulu nakweminye imimandla yehlabathi, ngoko ke inkoliso yemizila yezorhwebo iyadlula kuyo ukuya ecaleni. Imihlaba ayinotye kwiindawo eziphantsi, iindawo ezifanelekileyo kakhulu ezikusezantsi-mpuma. Kukho indawo ephambili yechweba yelizwekazi lase-Australia. Amanzi ahlamba i-Australia, afudumele nakwixesha lasebusika - engekho ngaphantsi kwe-20 degrees Celsius. Oku kudala indawo efanelekileyo yokukhokelwa kwee-corals, apho umda welizwekazikazi ukhula kakhulu. Kungenxa yesi sizathu kummandla wonxweme waseOstreliya udlula iReef Great Reef eyaziwayo, efikelela ubude beekhilomitha eziliwaka ezimbini.

Ngenxa yeendawo zayo, i-Australia yindawokazi ekude. Oku kwimiba emininzi kwathonya ukuphuhliswa kwayo ngokubhekiselele kwinkcubeko kunye neentlobo ezahlukeneyo zezilwanyana nezityalo.

Uncedo kunye namaminerali ase-Australia

Kwixesha elidlulileyo, leli zwekazi alizange lihlukaniswe nakwilizwe njengokuba ngoku, i-Ostraliya yayiyingxenye ebalulekileyo yeGondwana. Kodwa ekupheleni kwexesha leMesozoic, lahlukana kwaye laqala ukuhamba ngokukhawuleza kude lifike kwindawo yalo. Ngoku isiseko selizwekazi laseAustralia liyi-platform ye-Kneebrian ngaphambili, isiseko sayo esinekristallini. Kwezinye iindawokazi zelizwekazi, liza phezu komhlaba, lenze iinqweba, ngokukodwa kwimimandla esenyakatho, entshonalanga nephakathi. Kodwa ininzi yesikhulumi ifihliwe phantsi kobunzima beendwangu ze-sedimentary, imvelaphi yolwandle nolwandlekazi.

Iziqhamo eziqhakazileyo zokhuseleko lwelizwekazi laseAustralia zingabizwa ngolu hlobo lulandelayo: I-lowland ephantsi, ubude bayo abugqithanga ngaphezu kweemitha ezilikhulu ngaphezulu kwezinga elwandle; IiMounta zaseMpuma zaseAustralia, eziyiNtlukwano enkulu yoLuntu (ukuya kwiikhilomitha eziliwaka ukuphakama) kunye ne-West Australia yasePlateau. Kwakhona liphela lizwekazi kwihlabathi apho kungekho ziintaba ze-iced, kwaye akukho ziqhumane eziqhutyayo. Nangona ebudeni bexesha bekudlulileyo umsebenzi we-tectonic. Oku kubonakaliswa yimigodi emikhulu kunye neeponsi ezivela kwiintshonalanga zexesha elidlulileyo.

Iiminerali zase-Australia zizityebi kwiintlobo ezahlukeneyo. Ukufunyanwa kwezinto ze-Geological, ezenziwe kwiminyaka elishumi edlulileyo, zikwazi ukubeka kwindawo yokuqala zokukhutshwa kwe- iron ore, i- bauxite kunye ne-lead-zinc ores. Iimayaminithi ze- oreliya zase- Australia kwimaphu ziboniswa kwindawo yaseHamersley. Iifosti kule nqanaba ziye zaphuhliswa ngaphezu kwesigama sekhulu kwaye zingasongela ukuba ziphelelwe lixesha elizayo. I-iron ore iphinde ifakwe kwisiqithi esikhulu kunazo zonke kwilizwekazikazi-iTasmania, nakwiiqithi ezincinci kummandla wasentla-ntshona.

Iimbumba ze-polymetallic zase-Australia, ezibandakanya, okokuqala, i-zinc kwaye zikhokelela kunye ne-mix mix of copper kunye nesilivere, zifumaneka kwiindawo zenkangala zase-South Wales. Esinye isikhungo esibalulekileyo sokukhutshwa kwe-polymetals yi-Queensland kunye nesiqithi esele sathiwa ngu -Tasmania. Amashishini amancinci asasazeka kwilizwekazi lonke, kodwa ukumbiwa kwemigodi esebenzayo akuqhutywanga kuyo yonke indawo, njengalezi ngongoma eziphambili. Ukongeza, e-Australia kukho iindawo zokugcina zegolide. Eyona ndawo iphakamileyo kwiindawo ezisemgangathweni, amancinci angabonwa phantse nawaphi na ilizwe lizwe.

Umbuso waseMzantsi Wales uphinde udume ngokukhululeka kwawo kwelahle. Nangona le mineralari yindawo yonke kwimpuma yelizwekazi, uphuhliso oluphambili luwela kwizixeko zaseWales. Ukongezelela koku ngasentla, kungekude kudlulileyo, iimbotyi ezinkulu zegesi neoli zafunyanwa, ziphantsi kwiibilini zase-Australia. Abanye babo baye baphuhliswa ngempumelelo ngoku kutshanje. Eli lizwe livelisa ngokukhawuleza i-chrome, udongwe, isanti kunye ne-limestone.
