Umbhali waseNingizimu Afrika, usosayensi, umcwaningi, kanye nomhloli wamazwe uMichael Tellinger (oqanjwe ngokuthi “The South African Indiana Jones”) ubonisa lokho okungase kube esinye seziqephu ezibaluleke kakhulu ubufakazi bokuthi imidondoshiya ngaphambili yayizulazula eMhlabeni.
Izazi zokuma komhlaba ziye zamangala ngalesi sigxivizo esingamafidi angu-4 ubude kugwadle omangelengele. Abanye baphikisa ngokuthi isici sokuguguleka kwemvelo, nokho, kunzima ukusho okwamanje.
Ngokusho kukaProf Pieter Wagener waseNelson Mandela Metropolitan University ePort Elizabeth SA, onePhD kwi-application maths, “Kunamathuba amakhulu okuthi abafana abaluhlaza bafike bevela emkhathini futhi bawumunce ngolimi lwabo kunalokho okubangelwa ukuguguleka kwemvelo.” Itholakala eNingizimu Afrika, eduze komngcele waseSwazini, edolobheni laseMpaluzi.
Ngenxa yokuqonda kwethu kwamanje ukwakheka kwegwadle emlandweni womhlaba wonke, kukholakala ukuthi iphakathi kweminyaka eyizigidi eziyizinkulungwane ezingama-200 kuya kwezingu-3 ubudala. Lokhu kuqomisana ngokushesha kudala ukungezwani okushubile, ngakho-ke kuzoba ngcono ngathi ukuthi sibe nomqondo ovulekile futhi sigxile kudatha.
Lesi sibalo esimangalisayo se-granite satholwa ngo-1912 ngumzingeli ogama lakhe lingu-Stoffel Coetzee ngenkathi ezingela endaweni ekude. Ngaleso sikhathi, lesi kwakuyisifunda esiyincithakalo eNingizimu Afrika eyaziwa ngokuthi i-Eastern Transvaal, eyayigcwele izilwane ezinjenge-antelope namabhubesi.
Isesesimeni esifanayo nangesikhathi itholwa, futhi amathuba okuba inkohliso ehlushwayo mancane kakhulu ngenxa yendawo yayo engayodwa. Ngisho namanje, akuvamile ukuhlangana.
Impicabadala yeqiniso ukuthi le nto emangalisayo yenzeka kanjani ― cha, sinawo umbono ― kodwa isikhona futhi ngeke sikufise. Yebo, iyigwadle; kuyisici esaziwayo sokwakheka komhlaba eNingizimu Afrika, futhi sikhonjiswe kuwo wonke amashadi okwakheka komhlaba; yingakho umkhondo wezinyawo uyimfihlakalo.
Kungase kuchazwe ngokuthi a "phenocrystic" igwadule NOMA igwadule elimahhadla le-porphyritic elidlule ezigabeni zokupholisa eziningi. Umkhiqizo wokugcina uyinhlanganisela ethakazelisayo yezinhlamvu ezinkulu nezincane. Yingakho abathengisi be-granite befuna ukumba imayini kule ndawo njengoba i-granite izobukeka kakhulu "muhle" lapho iphucuziwe.
Lesi sitshalo saziwa ngokuthi yi-Mpuluzi Batholith (Granite) ku-Geology yaseNingizimu Afrika, futhi ukuqokwa okusemthethweni kwaleli dwala kwaveza izinsuku ezingaba yiminyaka eyizigidi eziyizinkulungwane ezingu-3.1. Lena imfumbe yangempela edinga uphenyo lwesayensi olunembayo.
