Txoj cai ntawm cov khoom tawg yog ib txoj hauv kev kwv tij sib tham hauv geology. Qhov tseem ceeb, txoj cai no hais tias cov pob zeb hauv pob zeb loj dua li pob zeb nws tus kheej. Ib piv txwv ntawm no yog ib tug xenolith, uas yog ib feem ntawm lub teb chaws pob zeb uas poob mus rau hauv magma dhau los ntawm kev nres.

Tsis tas li ntawd, hom kev txheeb ze yog dab tsi?

Ib txhia hom kev txheeb ze sib tham Cov tswv yim muaj xws li huab cua chronology, dendrochronology, ice core sampling, stratigraphy, thiab seriation.

Tsis tas li ntawd, dab tsi yog ib qho piv txwv ntawm kev sib tham tiag? Muaj kev sib tham yog tus txheej txheem ntawm kev txiav txim siab txog hnub nyoog ntawm ib lub sijhawm teev tseg hauv archaeology thiab geology. Cov txheej txheem muaj xws li ntoo rings nyob rau hauv ntoo, radiocarbon sib tham ntawm ntoo los yog pob txha, thiab trapped-charge sib tham cov txheej txheem xws li thermoluminescence sib tham ntawm glazed ceramics.

Ntawm no, piv txwv txog hnub nyoog txheeb ze yog dab tsi?

Cov hnub nyoog txheeb ze ntawm pob zeb lossis pob txha pob txha tsis yog tus lej lossis hnub nyoog ; nws yog kev sib piv ntawm ib pob zeb los yog pob txha mus rau lwm tus los txiav txim seb ib tug laus los yog hluas dua. kwv tij kev sib tham yog ua tiav los ntawm kev siv ntau yam txuj ci uas tuaj yeem siv tau yooj yim thaum geologists ua haujlwm hauv thaj chaw thiab tsis nyob hauv chav kuaj.

Peb txoj cai ntawm kev txheeb ze yog dab tsi?
