Karolo ea Majoe a Sedimentary Potolohong ea Khabone
Lefatše ke tikoloho e rarahaneng le e matla e akaretsang lipotoloho tse fapaneng tsa geochemical, e 'ngoe ea tsona ke potoloho ea khabone. Potoloho ea khabone ke letoto la lits'ebetso tseo khabone e tsamaeang ka tsona sepakapakeng, lithosphere, hydrosphere le biosphere. Majoe a sedimentary a bapala karolo ea bohlokoa potolohong ena, leha hangata a sa buisanoe haholo joaloka mesebetsi ea lintho tse phelang tse hlahisang photosynthesis kapa mafura a mesaletsa ea lintho tsa khale. Sengoloa sena se tla hlahloba karolo ea mafika a sedimentary potolohong ea khabone ka botebo, ho tloha ho thehoeng ha 'ona ho isa monehelong oa 'ona polokelong le ho lokolloeng ha khabone.
Ho thehoa ha Mafika a Sedimentary
Mokhoa oa ho thehoa ha lefika la sedimentary o qala ka ho putlama ha mafika holim'a Lefatše. Ho putlama ha lik'hemik'hale le 'mele ho qhaqha mafika hore e be likaroloana tse nyane, tse kang lehlabathe, seretse le letsopa. Likaroloana tsa lik'hemik'hale, ho kenyeletsoa le khabone, li ka lokolloa nakong ea ts'ebetso ena. Likaroloana tsena tse putlamang li tsamaisoa ke lintho tse fapaneng tse kang metsi, moea, kapa leqhoa 'me li beoa likarolong tse ncha. Ha nako e ntse e ea, likarolo tsena lia patoa, lia petsoha, 'me li feta ka bongata, qetellong li etsa mafika a sedimentary.
Hoo e ka bang 75% ea bokaholimo ba Lefatše e koahetsoe ke mafika a sedimentary, e leng libaka tsa mantlha tsa polokelo ea metsoako e fapaneng ea khabone, ho kenyeletsoa khabone ea tlhaho e tsoang masala a lintho tse phelang tse patiloeng le khabone e sa tloaelehang ka mokhoa oa liminerale tsa carbonate.
Mafika a Sedimentary e le Polokelo ea Khabone
Majoe a sedimentary a sebetsa e le matlo a polokelo bakeng sa khabone, ka bobeli ka mefuta ea lintho tse phelang le e seng ea lintho tse phelang. Majoe ana a boloka khabone nako e telele haholo, hangata lilemo tse limilione ho isa ho tse libilione.
1. Khabone ea tlhaho
– Masalla a limela le a liphoofolo a patiloeng mobung a ka qetella a fetohile mafura a mesaletsa ea lintho tse phelang joalo ka mashala, peterole le khase ea tlhaho ka mekhoa ea ho hlaha ha lintho tse phelang le ho fetoha ha tsona.
– Mekotlo ea mashala ke mohlala oa khale oa mafika a sedimentary a bolokang khabone e ngata ea tlhaho. Mashala a thehoa ka liqubu tse kholo tsa lintho tse phelang, tse kang masalla a limela, a patiloeng tlas'a maemo a anaerobic (a se nang oksijene) 'me a hatelloa ka lilemo tse limilione.
2. Khabone e sa pheleng
– Khabone e ka boela ea bolokoa mafikeng a sedimentary e le liminerale tsa carbonate tse kang calcite (CaCO3) kapa dolomite (CaMg(CO3)2).
– Ho thehoa ha mafika a carbonate a kang lejoe la mokoetla le dolomite hangata ho etsahala libakeng tse sa tebang tsa leoatle, moo li-ion tsa carbonate le li-ion tsa calcium li kopanang le ho pompa.
Mafika a Sedimentary a Hlahisitsoeng Khaboneng
Ntle le ho sebetsa e le polokelo, mafika a sedimentary a boetse a phetha karolo ea ho lokolla khabone tsamaisong ea Lefatše. Ho na le mekhoa e 'maloa eo khabone e lokolloang ka eona mafikeng a sedimentary:
1. Ho lokolloa ka Chemical Weathering
– Ts'ebetso ea lik'hemik'hale ea ho fetoha ha mafika ha e thehe feela mafika a sedimentary empa hape e ntša carbon dioxide sepakapakeng.
– Ha diminerale tsa khabone tse kang calcite di ntse di senyeha ka lebaka la dikhemikhale, khabone e ntshang khabone e ka kgutlisetswa sepakapakeng.
2. Mesebetsi ea seretse se chesang le ea lithaba
– Majoe a patiloeng a sedimentary a ka fetoha karolo ea bokaholimo bo tebileng ba Lefatše ka mokhoa oa ho kenella ha lintho tse phelang.
– Botebong bona, mafika a ka qhibiliha ho ba magma mme a nyolohela hodima metsi jwalo ka seretse se chesang nakong ya ho phatloha ha seretse se chesang, e leng se ntshang carbon dioxide.
3. Mesebetsi ea Batho
– Tšebeliso e mpe ea mafura a khale ke mohlala o motle oa kamoo khabone e bolokiloeng mafikeng a sedimentary e lokolloang hape sepakapakeng.
– Ho chesa mashala, oli le khase ea tlhaho bakeng sa matla ho fella ka ho lokolloa ha khabone e ngata, e leng se tlatsetsang ho futhumaleng ha lefatše le phetohong ea maemo a leholimo.
Mafika a Sedimentary le Thibelo ea Phetoho ea Tlelaemete
Ka ho eketseha ha temoho ea phetoho ea tlelaemete, ho utloisisa karolo ea mafika a sedimentary potolohong ea khabone ho ntse ho e-ba bohlokoa haholo. Ho na le litsela tse 'maloa tseo mafika a sedimentary a ka kenyang letsoho ho fokotseng phetoho ea tlelaemete ka tsona:
1. Ho Monya Khabone ka ho Theha Khabone
– Maano a kang Enhanced Weathering a ikemiseditse ho potlakisa ho fetoha ha mafika a nang le calcium kapa magnesium ions, a ka arabelang le carbon dioxide e tswang sepakapakeng ho etsa diminerale tsa carbonate, ka hona a boloka carbon ka ho sa feleng lefikeng.
2. Tšebeliso ea Geotechnical
– Ka ho sebedisa mekgwa ya geoengineering e kang Carbon Capture and Storage (CCS), carbon dioxide e hlahiswang mesebetsing ya diindasteri e ka tshwarwa mme ya kenngwa majweng a sedimentary a nang le masoba a mangata mme a kgona ho boloka kgase nako e telele.
Qetello
Bohlokoa ba mafika a sedimentary potolohong ea khabone hangata bo hlokomolohuoa, leha ho le joalo karolo ea bona ke ea bohlokoa ho bolokeng botsitso ba khabone ea Lefatše. Mafika a sedimentary ha a boloke khabone e ngata feela ka mefuta ea lintho tse phelang le tse sa pheleng, empa hape a bapala karolo ts'ebetsong ea tlhaho ea ho lokolloa ha khabone sepakapakeng. Ka ho utloisisa karolo ena, re ka laola mehloli ea Lefatše ka bohlale haholoanyane 'me ra fumana litharollo tsa ho fokotsa litlamorao tsa phetoho ea tlelaemete. Ho etsa lipatlisiso le ho nts'etsapele mahlale a sebelisang karolo ea tlhaho ea mafika a sedimentary e ka ba mohato oa bohlokoa ho fokotseng phetoho ea tlelaemete nakong e tlang.
