Nako ea nalane ea Lefatše e lekantsoe ke sekala se ikhethileng sa geochronological, se nang le linako tsa jioloji le limilione tsa lilemo. Lipontšo tsohle tsa tafole li hatella haholo mme ka kakaretso lia amoheloa ho bo-ramahlale boemong ba machabeng. Ka kakaretso, lilemo tsa polanete ea rona li qalile lilemong tse ka bang limilione tse 4,5-4,6. Liminerale le majoe a ho ratana joalo ha li so fumanoe lithosphere, empa lilemo tsa lefats'e li ne li khethiloe ke libopeho tsa pele-pele tse fumanoeng tsamaisong ea letsatsi. Tsena ke lintho tse nang le aluminium le calcium tse fumanoang Allende, meteorite ea khale ka ho fetisisa e fumanoeng polaneteng ea rona.
Tafole ea geochronological e amohetse lekholong la ho qetela la lilemo. E re lumella ho ithuta nalane ea Lefatše, empa tlhaiso-leseling e re lumellang ho nahana le ho akaretsa. Tafole ke mofuta oa nako ea tlhaho ea nalane ea polanete.
Melao-motheo ea ho aha tafole ea jiokronoloji
Likarolo tsa mantlha tsa tafole ea Lefatše ke tsena:
- eon;
- mehla;
- nako;
- mehla;
- ea selemo.
Nalane ea Lefatše e tletse liketsahalo tse fapaneng. Nako ea bophelo ea polanete e arotsoe ka linako tse kang Phanerozoic le Precambrian, moo majoe a sedimentary a hlahileng, ebe ho tsoaloa lintho tse nyane, hydrosphere le motheo oa polanete. Li-supercontinents (Vaalbara, Colombia, Rodinia, Mirovia, Pannotia) li hlahile khafetsa mme tsa arohana. Ho feta moo, sepakapaka, litsamaiso tsa lithaba, lik'honthinente li ile tsa theoa, lintho tse phelang tse fapaneng tsa hlaha mme tsa shoa. Linako tsa likoluoa le glaciation tsa lefatše li hlahile.
Ho ipapisitsoe le tafole ea geochronological, liphoofolo tsa pele tse nang le lisele tse ngata polaneteng li hlahile lilemo tse ka bang limilione tse 635 tse fetileng, li-dinosaurs - limilione tse 252, le liphoofolo tsa sejoale-joale - lilemo tse limilione tse 56. Ha e le batho, litšoene tse kholo tsa pele li hlahile lilemo tse ka bang limilione tse 33.9 tse fetileng, le batho ba sejoale-joale lilemong tse limilione tse 2,58 tse fetileng. Ke ka ponahalo ea motho lefats'e le qalang nako ea anthropogenic kapa Quaternary, e ntseng e tsoela pele ho fihlela kajeno.
Re phela nako mang ha joale
Haeba re khetholla mehla ea lefats'e ho latela ponahalo ea tafole ea geochronological, joale re tla phela:
- Phonerozoic eon;
- nakong ea Cenozoic;
- ka nako anthropogenic;
- nakong ea Anthropocene.
Hajoale, batho ke e 'ngoe ea lintlha tsa mantlha tikolohong ea lefatše. Boiketlo ba Lefatše bo its'etleha ho rona. Ho senyeha ha tikoloho le mefuta eohle ea likoluoa ho ka lebisa lefung la batho bohle, empa le lintho tse ling tse phelang tsa "polanete e putsoa".
