Depositional ib puag ncig:
- Continental: Fluvial. Alluvial. Dej khov. Eolian. Lacustrine. Paludal.
- Hloov pauv: Deltaic. Esturine. Lagoonal. Puam.
- Marine: Nyias marine clastic. Carbonate txee. Continental txoj kab nqes. Dej hiav txwv tob.
Hais txog qhov no, dab tsi yog peb lub ntsiab ntawm qhov chaw depositional?
Qhov ntau depositional ib puag ncig uas tuaj yeem muab faib ua peb pawg loj - dej hiav txwv , transitional, thiab teb chaws Europe . Saib cov lus hauv paus ntawm qhov chaw depositional rau cov ncauj lus kom ntxaws ntxiv ntawm txhua pawg thiab cov pob zeb sedimentary, cov qauv thiab cov fossils uas muaj rau txhua qhov chaw.
Ib yam li ntawd, koj yuav txheeb xyuas qhov chaw depositional li cas? Rau txheeb xyuas qhov chaw depositional , geologists, zoo li cov kws tshawb nrhiav kev ua txhaum cai, nrhiav cov lus qhia. Cov kws tshawb nrhiav tuaj yeem nrhiav ?ngerprints thiab bloodstains rau txheeb xyuas ib tug ua txhaum. Geologists tshuaj xyuas qhov luaj li cas, muaj pes tsawg leeg, sorting, txaj-surface marks, ntoo khaub lig txaj, thiab fossils. txheeb xyuas a depositional ib puag ncig.
Tom qab ntawd, lo lus nug yog, dab tsi yog 4 ib puag ncig ntawm kev tso nyiaj?
Depositional ib puag ncig . Sedimentary pob zeb yog tsim los ntawm 5 txheej txheem, muaj erosion, weathering, thauj, tso nyiaj , thiab cov txheej txheem diagenesis (Boggs, 1991). Cov 5 txheej txheem nrog 4 hom pob zeb ua ib lub voj voog uas hu ua sedimentary cycle.
Dab tsi yog qhov sib txawv sedimentary ib puag ncig?
Hom ntawm depositional ib puag ncig Fluvial - cov txheej txheem vim txav dej, feem ntau ntws. Feem ntau sediments yog gravel, xuab zeb, thiab silt. Lacustrine - cov txheej txheem vim txav dej, feem ntau yog pas dej. Feem ntau sediments yog xuab zeb, silt, thiab av nplaum.
