Qhov thickening no tshwm sim los ntawm conductive txias , uas hloov kub asthenosphere mus rau lithospheric mantle thiab ua rau dej hiav txwv lithosphere oceanic lithosphere Lub Oceanic crust yog the topmost txheej ntawm lub ib feem ntawm dej hiav txwv tectonic phaj. Nws yog tsim los ntawm sab sauv dej hiav txwv crust, nrog rau hauv ncoo lavas thiab ib tug dike complex, thiab nyob rau hauv lub sab dej hiav txwv crust, muaj li ntawm troctolite, gabbro thiab ultramafic cumulates. Lub crust overlies lub solidified thiab topmost txheej ntawm lub mantle. https://en.wikipedia.org › wiki › Oceanic_crust

Oceanic crust - Wikipedia

ua kom tuab thiab ntom nrog hnub nyoog. Qhov tseeb, dej hiav txwv lithosphere yog txheej txheej thermal ciam teb rau cov convection hauv lub mantle.

Vim li cas cov lithosphere tuab?

Dej hiav txwv lithosphere thickens raws li nws muaj hnub nyoog thiab txav deb ntawmtus ntug dej hiav txwv nruab nrab. Qhov thickening no tshwm sim los ntawm kev ua kom txias, uas hloov cov kub asthenosphere mus rau hauv lub lithospheric mantle, thiab ua rau cov dej hiav txwv lithosphere nce zuj zus nrog hnub nyoog.

Dab tsi txiav txim siab tuab ntawm lithosphere?

Cratonic continental lithosphere tuaj yeem tuab dua 200 km thiab muaj sia nyob rau ntau txhiab xyoo. Qhov no feem ntau ascribed rau ntau dua buoyancy thiab lub zog ntawm cratonic lithospheric mantlepiv rau cov hluas lithosphere. … Lwm yam tseem ceeb rau lub rheology ntawm lub mantle yog cov ntsiab lus dej.

yog dab tsilithosphere Nws tuab npaum li cas thiab nws tsim los ntawm dab tsi?

Dej hiav txwv lithosphere feem ntau yog kwv yees li 50-100 km tuab (tab sis hauv qab cov ntug dej hiav txwv nruab nrab tsis tuab dua li cov crust), thaum lub teb chaws lithosphere yog li 150 km tuab, muaj 50 km ntawm crust thiab 100km los yog ntau tshaj ntawm lub uppermost mantle.

Nyob rau hauv uas ciam teb lithosphere yog thickened?

Lub asthenosphere yog ua los ntawm cov pob zeb yaj uas ua rau nws tuab, nplaum sib xws. Lub lithosphere-asthenosphere ciam teb (LAB) yog qhov chaw uas cov lithosphere khoom hloov mus rau asthenosphere. Qhov tob ntawm LAB tsis kho, tab sis hloov pauv ntawm qhov chaw mus rau qhov chaw. … Oceanic lithosphere yog me ntsis denser.
