Kev tsis sib haum xeeb yog qhov dav dav sib cais cov pob zeb saum toj thiab hauv qab, uas sawv cev rau qhov sib txawv ntawm cov ntaub ntawv pob zeb. Kev tsis sib haum xeeb tshwm sim thaum kev yaig los ntawm pob zeb, lossis pob zeb tsis tau tsim. Yog li ntawd, ib lub sij hawm sib txawv nyob nruab nrab ntawm thaum lub pob zeb nyob rau hauv lub unconformity tsim thiab thaum cov saum toj no nws tsim.
Yuav ua li cas thaum tsis sib haum xeeb tshwm sim?
Muab tso tseg, qhov tsis sib haum xeeb yog qhov tawg ntawm lub sijhawm hauv cov ntaub ntawv pob zeb txuas ntxiv. Unconformities yog ib hom ntawm geological contact-ib ciam teb ntawm pob zeb-ua los ntawm ib lub sij hawm ntawm erosion los yog ib tug ncua nyob rau hauv sediment tsub kom, raws li los ntawm deposition ntawm sediments anew.
Cov xwm txheej geological dab tsi yog Unconformities?
Kev tsis sib haum xeeb yog QHOV TSEEB NTAWM LUB TSEV KAWM NTAWV NTAWM UPLIFT, EROSION THIAB SUBSIDENCE thaum lub sij hawm kev loj hlob ntawm lub teb chaws raws li lub ntiaj teb keeb kwm kev loj hlob. Lawv yog li ntawd yog cov pov thawj tseem ceeb rau CrustAL MOBILITY thoob plaws ntiaj teb keeb kwm.
Dab tsi yog qhov tsis sib haum xeeb hauv kab ke geology?
Kev tsis sib haum xeeb yog qhov chaw nyob hauv cov ntaub ntawv pob zeb, hauv kab ntawv stratigraphic, sawv cev rau lub sijhawm uas tsis muaj pob zeb tau khaws cia. Nws tuaj yeem sawv cev rau lub sijhawm uas tsis muaj pob zeb tsim, lossis lub sijhawm uas pob zeb tau tsim tab sis tom qab ntawd eroded.
Dab tsi yog qhov tsis sib haum xeeb sawv cev ntawm lub sijhawm geology?
Kev tsis sib haum xeebsawv cev lub sijhawm uas tsis muaj sediments tau khaws cia hauv ib cheeb tsam. Cov ntaub ntawv hauv zos rau lub sijhawm ntawd ploj lawm thiab geologists yuav tsum siv lwm cov lus qhia los tshawb pom ib feem ntawm keeb kwm ntawm thaj chaw ntawd. Lub caij nyoog ntawm geological lub sij hawm tsis sawv cev yog hu ua hiatus.
