Qhov kev tsis sib haum xeeb yog qhov faus erosional lossis tsis-depositional nto sib cais ob lub pob zeb loj lossis strata ntawm cov hnub nyoog sib txawv, qhia tias sediment deposition tsis tas mus li.
Dab tsi yog qhov tsis sib haum geology?
1. n. [Geology] Ib qhov chaw geological uas cais cov menyuam yaus overlying sedimentary strata ntawm eroded igneous los yog metamorphic pob zebthiab sawv cev rau qhov sib txawv loj hauv cov ntaub ntawv geology.
Kev tsis sib haum xeeb li cas?
Ib qhov tsis sib haum xeeb tshwm sim ntawm pob zeb sedimentary thiab cov pob zeb metamorphic lossis igneous pob zeb thaum cov pob zeb sedimentary nyob saum toj no thiab tau tso rau ntawm cov pob zeb uas twb muaj lawm thiab eroded metamorphic lossis igneous pob.
Ib qho piv txwv ntawm kev tsis sib haum xeeb hauv geology yog dab tsi?
Piv txwv li, kev sib cuag ntawm 400-million-xyoo-laus xuab zeb uas tau tso los ntawm lub hiav txwv nce siab rau saum npoo av uas muaj hnub nyoog 600 lab xyoo yog ib qho unconformity uas sawv cev rau lub sij hawm hiatus ntawm 200 lab xyoo.
Kev tsis sib haum xeeb thiab tsis sib haum yog dab tsi?
Ib qho tsis sib xws yog qhov nws hu ua thaum cov pob zeb sedimentary strata tshaj crystalline (metamorphic lossis igneous) strata. A kev tsis sib haum yog thaum lub sedimentary strata hla lwm sedimentary strata.
