Pob zeb tuaj yeem teb rau kev ntxhov siab hauv peb txoj kev: nws tuaj yeem deform elastically, nws ua tau deform plastically, thiab nws tuaj yeem tawg lossis tawg. Elastic strain yog reversible; yog tias qhov kev ntxhov siab raug tshem tawm, lub pob zeb yuav rov qab mus rau nws qhov qub zoo ib yam li cov roj hmab band uas yog stretched thiab tso tawm.
Nyob rau hauv txoj kev no, dab tsi yog elastic deformation geology?
elastic deformation : lub pob zeb rov qab mus rau nws qhov qub qub thaum qhov kev ntxhov siab raug tshem tawm. yas deformation : lub pob zeb tsis rov qab mus rau nws qhov qub qub thaum qhov kev ntxhov siab raug tshem tawm. tawg: pob zeb tawg.
Qhov thib ob, puas pob zeb stretch? Pob zeb nyob rau hauv lub active phaj ciam teb yog raug rau lub cev kev nyuaj siab. Lawv ua tau compression (xws li compression), ncab (nruj), los yog thawb rau hauv kev sib txawv (shear stress). Thaum twg pob zeb khoov los yog ntws, zoo li av nplaum, nws yog hu ua ductile deformation.
Ib yam li ntawd ib tug yuav nug, dab tsi ua rau deformation ntawm pob zeb?
Pob zeb Puas Muaj Kev Nyuaj Siab ua rau pob zeb rau deform , meaning the pob zeb hloov qhov loj los yog duab. Shear stress yog thaum pob zeb swb nyob rau hauv ib txoj kab rov tav. Nrog shear stress, lub pob zeb raug rub tawm hauv cov lus qhia sib txawv tab sis ntawm qhov sib txawv.
Dab tsi yog hom pob zeb deformation?
Muaj peb hom pob zeb deformation . Elastic deformation yog ib ntus thiab thim rov qab thaum lub hauv paus ntawm kev ntxhov siab raug tshem tawm. Ductile deformation yog irreversible, uas ua rau muaj kev hloov mus tas li rau cov duab lossis qhov loj ntawm lub pob zeb qhov ntawd tseem nyob txawm tias thaum kev ntxhov siab nres.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Lub pob zeb twg loj dua pob zeb?
Sedimentary pob zeb tuaj yeem ua los ntawm cobbles. Cobbles yog pob zeb uas loj dua pebbles tab sis me dua pob zeb. Conglomerate thiab breccia yog
Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
