Ukuhlola I-Geology Yeso Lengwe Eliphuzi: Lakhiwa Kanjani Leli Litshe Eliyigugu nokuthi Lingatholakalaphi
Dec
Ihlo lehlosi eliphuzi liyitshe eliyigugu elihle neliyingqayizivele elaziswa kakhulu ngabaqoqi nabathanda ubucwebe. Kodwa ingabe wake wazibuza ukuthi lelitshe eliyigugu lakhiwa kanjani futhi litholakala kuphi? Kulokhu okuthunyelwe kwebhulogi, sizocubungula i-geology yehlo lengwe eliphuzi futhi sifunde ngohambo lwayo oluhehayo ukusuka kumaminerali aluhlaza kuya kumatshe ayigugu amahle.
Ihlo lehlosi eliphuzi liwuhlobo lwe asebenza ngebhethri, i-mineral etholakala ezingxenyeni eziningi zomhlaba. I-quartz yenziwe nge-silicon dioxide, futhi ingenzeka ngemibala ehlukahlukene namafomu, okuhlanganisa cacisa i-quartz, rose quartz, Futhi amethiste. Ihlo lehlosi eliphuzi liwuhlobo lwe-quartz olunemibala ngokuba khona kwe-iron oxide, elinikeza umbala walo ophuzi ohlukile.
Ngakho-ke i-quartz iba iso lengwe eliphuzi? Inqubo ye-metamorphism idlala indima ebalulekile ukuqeqeshwa yalelitshe eliyigugu. I-Metamorphism ukuguqulwa kwamadwala namaminerali ngokushisa, ukucindezela, nokusabela kwamakhemikhali. Lapho i-quartz iba ne-metamorphism, ingathatha uhlobo olusha futhi ibe amatshe ayigugu ahlukahlukene, kuhlanganise neso lengwe eliphuzi.
Inqubo eqondile ye-metamorphism eholela ekwakhekeni kwehlo lehlosi eliphuzi ayiqondwa ngokugcwele, kodwa kucatshangwa ukuthi ihilela ukunyakaza koketshezi olune-iron ku-quartz. Lolu ketshezi luqukethe i-iron oxide, eyenza i-quartz ibe nombala ophuzi. Le nqubo ingase futhi ihilele ukwakheka kwamakristalu ane-fibrous, anikeza iso lengwe eliphuzi ukuxoxa kwalo okuyisici, or "iso lekati" umphumela.
Ihlo lehlosi eliphuzi lingatholakala ezindaweni ezihlukahlukene emhlabeni jikelele, kuhlanganise neNingizimu Afrika, Australia, kanye nezwe I-united states. ENingizimu Afrika, iso lengwe eliphuzi livame ukutholakala esiFundazweni saseNyakatho Kapa, lapho limbiwa khona ukuze lisetshenziswe ubucwebe nezinye izinto zokuhlobisa. E-Australia, iso lengwe eliphuzi litholakala esifundazweni saseNtshonalanga Australia, futhi laziwa ngombala walo ogqamile nonelanga. E-United States, iso tiger yellow ingatholakala uthi ezifana California futhi Arizona.
Ngaphandle kobuhle bayo, iso lengwe eliphuzi liyaziswa futhi ngenxa yezakhiwo zalo zokuphulukisa. Kuthiwa iletha ukucaca nokugxila engqondweni, futhi kukholakala ukuthi inemiphumela eqinisayo nethobisayo kumuntu oyigqokile. Ihlo lehlosi eliphuzi libuye lihlotshaniswe nokuchichima nokuchuma, futhi kucatshangwa ukuthi lisiza ukuheha inhlanhla nempumelelo yezezimali.
Sengiphetha, iso lengwe eliphuzi liyitshe eliyigugu elithakazelisayo eline-geology eyingqayizivele neyinkimbinkimbi. Yakheka ngenqubo ye-metamorphism, iso lengwe eliphuzi lakhiwa i-quartz eliye lashintshwa ukushisa, ukucindezela, nokusabela kwamakhemikhali. Lelitshe eliyigugu lingatholakala ezindaweni ezihlukahlukene emhlabeni jikelele futhi laziswa ngobuhle balo kanye nezindawo zokuphulukisa. Uma ungumuntu othanda amatshe ayigugu, iso lengwe eliphuzi kufanele nakanjani lihlolwe!
