Yog li, pob zeb sedimentary thiab metamorphictsis tuaj yeem yog hnub tim radiometrically. Txawm hais tias tsuas yog pob zeb uas tsis muaj zog tuaj yeem suav nrog hnub nyoog, hnub nyoog ntawm lwm hom pob zeb tuaj yeem raug txwv los ntawm cov hnub nyoog ntawm cov pob zeb uas tsis muaj zog uas lawv tau cuam tshuam.
Vim li cas cov pob zeb sedimentary feem ntau tsis tuaj yeem sau hnub tim xov tooj cua?
Radioactive cov ntsiab lus lwj ntawm tus nqi tas mus li thiab qhov no yog lub hauv paus ntawm kev sib tham xov tooj cua. … Cov pob zeb sedimentary tej zaum yuav muaj cov khoom siv hluav taws xob hauv lawv, tab sis lawv tau rov ua haujlwm los ntawm lwm cov pob zeb, yog li qhov tseem ceeb, muaj lub moos xov tooj cua tsis tau muab rov qab mus rau xoom.
Cov pob zeb sedimentary puas tuaj yeem muaj xov tooj cua hnub tim?
feem ntau cov pob zeb sedimentary thaum ub tsis tuaj yeem sau hnub tim radiometrically, tab sis txoj cai ntawm kev sib raug zoo thiab kev sib raug zoo tuaj yeem siv los tso lub sijhawm txwv rau cov txheej ntawm cov pob zeb sedimentary crosscut lossis bounded los ntawm radiometrically hnub tim igneous rocks.
Vim li cas Geologists tsis tuaj yeem pom cov pob zeb sedimentary ncaj qha?
Vim li cas geologists tsis tuaj yeem hnub tim pob zeb sedimentary ncaj qha? Cov pob zeb sedimentary tseem yau dua li lawv cov pob zeb sib xyawCov pob zeb qub tshaj plaws uas paub tias yog 4.4 lab xyoo zircon siv lead ua pom nyob rau hauv cov xuab zeb qub. … Lub sandstone muaj hnub nyoog qis dua 4.4 billion xyoo.
pob zeb radiometrically hnub tim li cas?
txhawm rau tsim lub hnub nyoog ntawm pob zeb lossis pob txha pob txha, cov kws tshawb fawb siv qee hom moos los txiav txim hnub nws tau tsim. Geologists feem ntau siv xov tooj cua sib tham txoj hauv kev, raws li ntawm lub ntuj tawg ntawm qee yam ntsiab lus xws li potassium thiab carbon, raws li lub moos txhim khu kev qha rau hnub qub txheej xwm.
