Geochronology yog kev tshawb fawb ntawm kev txiav txim siab hnub nyoog ntawm pob zeb, pob txha, thiab sediments siv kos npe hauv pob zeb lawv tus kheej. Tsis muaj geochronology tuaj yeem ua tiav los ntawm cov xov tooj cua isotopes, qhov txheeb ze geochronology yog muab los ntawm cov cuab yeej xws li palaeomagnetism thiab ruaj khov isotope ratios.
Lub ntsiab lus ntawm geochronology yog dab tsi?
Geochronology, teb ntawm kev tshawb fawb txog kev txiav txim siab hnub nyoog thiab keeb kwm ntawm lub ntiaj teb pob zeb thiab pob zeb sib sau.
geochronology siv rau dab tsi?
Geochronology yog qhov tsis tseem ceeb cuab yeej rau kev rov tsim kho cov geodynamic evolution ntawm orogenic siv, yos qhov chaw ntawm plutonic lossis volcanic pob zeb, metamorphic txheej xwm, sediment deposition thiab txiav txim siab hnub nyoog ntawm qhov chaw. pob zeb los ntawm cov sedimentary detritus yog muab los.
Geochronological units yog dab tsi?
Chronostratigraphic units yog lub cev ntawm pob zeb, txheej lossis tsis muaj txheej, uas tau tsim thaum lub sijhawm teev tseg ntawm lub sijhawm geological. Cov chav nyob ntawm lub sijhawm geology thaum lub sijhawmchronostratigraphic units tau tsim yog hu ua geochronologic units.
Dab tsi yog qhov txawv ntawm geochronology thiab Chronostratigraphy?
Chronostratigraphy-"Lub ntsiab ntawm stratigraphy uas cuam tshuam nrog lub sijhawm txheeb ze thiab hnub nyoog ntawm lub cev pob zeb." Geochronology-" Kev tshawb fawb ntawm kev sib tham thiab txiav txim siab lub sijhawm ua ntu zus ntawmCov xwm txheej hauv keeb kwm ntawm Lub Ntiaj Teb."
