Mokhatlo oa Machaba oa Lisaense tsa Geological (IUGS)

International Union of Geological Sciences (IUGS) e thehiloe ka 1961 ho arabela tlhokeho ea ho hokahanya mananeo a lipatlisiso tsa machaba a thuto ea mahlale a lefats'e ka mokhoa o tsoelang pele lipakeng tsa International Geological Congresses tse 'nileng tsa tšoaroa lilemo tse ling le tse ling tse nne ho tloha ka 1875.

Beijing, 1996, Lekhotla la IUGS le laetse Komiti ea Phethahatso ho theha moralo oa leano o tla etsa hore IUGS e be ea sejoale-joale le ho thusa ho beha lintho tsa eona tse tlang pele tsa saense. Ka 2000, Lekhotla le ne le amohetse leano le hlalosang morero oa Kopano bocha: IUGS ke ho kopanya sechaba sa lefats'e sa jeoloji ho (i) ho khothaletsa nts'etsopele ea mahlale a Lefatše ka tšehetso ea lithuto tsa mahlale tse pharalletseng tse amanang le tsamaiso eohle ea Lefatše, le (ii) ho sebelisa liphetho tsa liphuputso tsena le tse ling ho baballa tikoloho ea tlhaho ea Lefatše, ho sebelisa mehloli eohle ea tlhaho ka bohlale, le ho ntlafatsa katleho ea lichaba le boleng ba bophelo ba batho.

IUGS e batla ho matlafatsa ponahalo ea mahlale a lefats'e le ho bonts'a bohlokoa ba mahlale a lefats'e moralong oa tikoloho ea lefats'e. E le ho phethahatsa sena IUGS e sisintse ho thakgola Selemo sa Matjhaba sa Lefatshe ka tshebedisano mmoho le UNESCO le mekgatlo e meng ya UN e tla sebetsa e le tsela ya ho tsebisa ka bohlokwa ba mahlale a lefatshe le lefatshe.

Lenaneo la Boditšhabatšhaba la Kgolaganyo ya Dijioloji (IGCP) le tshegeditswe ke UNESCO le IUGS go tloga ka 1972. Ga jaana, IGCP e akaretsa ditšhaba di le 140 le diketekete tsa baitseanape ba lefatshe. Liperesente tse mashome a tšeletseng tsa linaha tse amehang ho IGCP li thathamisitsoe e le tse ntseng li tsoela pele. Lenaneo lena le 'nile la nkoa e le koloi e sebetsang hantle haholo bakeng sa ho fetisetsa tlhahisoleseding le koetliso ea thuto ea saense ho tloha linaheng tse tsoetseng pele ho ea linaheng tse tsoelang pele. Sena se sebetsa ho phethahatsa maikemisetso a Kopano a ho aha bokgoni.

IUGS le mokhatlo oa bona o tlas'a ICSU, IUGG, ba tsoelapele ho tšehetsa Komiti ea Saense ea ICSU e mabapi le Lithosphere (SCL) e shebaneng le matla, tšimoloho le phetoho ea bokaholimo ba lefats'e le mantle a kaholimo (lithosphere) mme e lebisa tlhokomelo e khethehileng lik'honthinenteng. le likarolo tsa bona.
Lithahasello tse khethehileng tsa saense le lithuto tsa thuto li emeloa ka har'a Union ka Mekhatlo e Kopanetsoeng ea eona, ke hore, mekhatlo e meholo ea machaba e ikemetseng e arolelanang le IUGS thahasello ea ho rera le ho etsa mesebetsi e itseng ea mahlale le likopano tse molemong oa bobeli.

Ka litho tsa eona tse emetseng linaha le libaka tse 115, li-commissions tse 8, lihlopha tse sebetsang tse 4 le mekhatlo e 38 e ikopantseng, IUGS ke e 'ngoe ea mekhatlo e meholo ka ho fetisisa le e sebetsang ka ho fetisisa ea saense lefatšeng.
