S-planes lossis schistosité dav hlau feem ntau txhais tau los ntawm cov ntaub npog uas tshwm sim los ntawm kev sib dhos ntawm micas lossis platy minerals. Txhais lub flattened ntev-axis ntawm strain ellipse. … Lub kaum sab xis ntawm C thiab S dav hlau yog ib txwm mob heev, thiab txhais qhov kev txiav txim siab. Feem ntau, qhov qis C-S lub kaum sab xis ntau dua.
Dab tsi yog shearing hauv phaj tectonics?
Kev piav qhia. Shearing tuaj yeem piav qhia raws li qhov txav txav ntawm ib lub pob zeb tawm tsam lwm qhov. Cov lus tsa suab no hloov cov pob zeb, ua rau lawv hloov pauv raws li lawv swb tawm tsam ib leeg.
shear zone txhais li cas?
Shear zones yog cov yam ntxwv tseem ceeb tshaj plaws thiab sawv cev deformation cov cim hauv orogenic sivLawv yog cov chaw uas nyiam kev pab ntawm deformation thiab cov txheeb ze txav ntawm cov crustal blocks nyob rau hauv Phanerozoic thiab Proterozoic orogens.
Dab tsi ua rau thaj chaw shear?
Ib cheeb tsam shear yog ib qho tseem ceeb heev ntawm cov txheej txheem tsis tu ncua nyob rau hauv lub ntiaj teb crust thiab sab sauv mantle. Nws ua raws li lus teb rau inhomogeneous deformation partitioning strain rau hauv cov phiaj xwm lossis curviplanar high-strain zones Intervening (crustal) blocks nyob twj ywm tsis cuam tshuam los ntawm deformation.
Txoj kev nyuaj siab ntawm pob zeb yog dab tsi?
Shear stress yog qhov kev ntxhov siab sib npaug mus rau qhov chaw muab, xws li lub dav hlau txhaum, uas tshwm sim los ntawm cov quab yuam ua tib yam rau saum npoo lossis los ntawm cov chaw taws teeb xa mus los ntawm ib puag ncig rock.
