Foliation vs Layering

Foliation thiab txheej tam sim no ua qauv hauv ob qho tib si sedimentary thiab metamorphic pob zeb. Qhia qhov sib txawv ntawm ob qho tib si yuav ua rau muaj kev ntsuam xyuas lub cev ntawm cov pob zeb sib txawv, txawm tias pom cov khoom siv los yog saib cov pob zeb nyob ze. Ob qho tib si foliation thiab txheej txheej yog siv rau lub hom phiaj geological.

Foliation los ntawm kev txhais txhais tau tias tus qauv nkag mus uas yog vim kev hloov kho ntawm cov zaub mov xws li mica minerals. Foliation kuj tseem siv los piav txog lub cev lub cev ntawm cov pob zeb metamorphic. Yog li ntawd, metamorphic pob zeb foliation yog ib yam khoom ntawm cov kev taw qhia kev ntxhov siab. Txhawm rau txiav txim siab qhov kev taw qhia luv luv, kev soj ntsuam ze ntawm qhov tsim ntawm qhov perpendicular yuav tsum tau ua.

Txoj kev

Ntawm qhov tod tes, txheej txheej tuaj yeem piav qhia raws li kev tsim cov txheej pob zeb hla lwm qhov. Cov pob zeb me me uas muab tso rau ntawm cov pob zeb sedimentary yuav cuam tshuam txog hom ib puag ncig thaum lub sijhawm nws tso. Hauv lwm lo lus, cov pob zeb sedimentary nrog txheej txheej yuav muaj nyias txheej ntawm ntxhib thiab nplua sediments los yog tawg. Raws li kev soj ntsuam ze, ib tus yuav tuaj yeem pom cov cim, cov pob txha thiab cov pob txha mos deformation.

Qhov txawv ntawm Foliation thiab Txheej

Yuav kom sib txawv foliation thiab txheej, cia peb pib nrog lawv tsim li cas. Foliation yog raws li lub hauv paus ntsiab lus ntawm kev ntxhov siab thaum txheej txheej yog tshwm sim los ntawm me me mica fragments embedded rau ntawm pob zeb. Foliation yog tsim los ntawm hluav taws thiab kev ntxhov siab; txheej txheej yog tshwm sim los ntawm nyias embedding ntawm ob coarse thiab nplua deposits. Tsis tas li ntawd, foliation yog vim kev hloov pauv ntawm cov zaub mov los ntawm tshav kub thiab siab. Txheej, ntawm qhov tod tes, yog raws caij nyoog lossis kev tshwm sim. Hais txog lub cev nam, foliation muaj txheej los yog striations thaum txheej txheej muaj cov cim rau lawv.

Ob qho tib si foliation thiab txheej txheej yuav pab geologist nkag siab txog kev txav axial tshwj xeeb lossis hloov raws caij nyoog nyob rau lub sijhawm. Qhov no yog ib qho kev kawm tshwj xeeb hauv geology uas txaus siab rau ntau tus tub ntxhais kawm. Kev nkag siab txhua yam yuav siv sij hawm tab sis muaj peev xwm kawm qhov txawv yuav pab tau tiag tiag.

In luv:

• Foliation yog tshwm sim los ntawm hluav taws kub thiab kev ntxhov siab thaum txheej txheej yog tshwm sim los ntawm nyias embedding ntawm ntxhib thiab nplua deposits los yog sediments.

• Foliation yog vim kev hloov pauv ntawm cov zaub mov los ntawm tshav kub thiab siab thaum txheej txheej yog tshwm sim los ntawm kev hloov raws caij nyoog.

• Foliation muaj txheej lossis striations thaum txheej txheej muaj cov cim rau lawv
