Sediments kuj raug cais los ntawm keeb kwm. Muaj plaub hom: lithogenous, hydrogenous, biogenous thiab cosmogenous. Lithogenous sediments tuaj ntawm av los ntawm cov dej ntws, dej khov, cua thiab lwm yam txheej txheem.
Yuav ua li cas yog cov sediments?
Muaj peb hom sediment, thiab yog li ntawd, cov pob zeb sedimentary: clastic, biogenic, thiab tshuaj, thiab peb sib txawv peb raws li cov khoom tawg ua ke los tsim lawv. Cia peb saib thawj hom hais, uas yog clastic. Clastic sediments yog tsim los ntawm cov pob zeb tawg.
4 sediment keeb kwm yog dab tsi?
Peb faib cov sediments marine los ntawm lawv qhov chaw. Plaub hom sediment tseem ceeb yog lithogenous, biogenous, hydrogenous thiab cosmogenous(Table 1 hauv qab). Hauv chav kuaj no, koj feem ntau yuav tshuaj xyuas lithogenous, biogenous, thiab hydrogenous sediments. Tag nrho peb hom sediment tseem ceeb rau ntau yam.
3 hom sediment yog dab tsi?
Cov pob zeb sedimentary yog tsim los ntawm cov khoom ntawm lwm cov pob zeb uas twb muaj lawm lossis cov khoom siv organic. Muaj peb yam sib txawv ntawm cov pob zeb sedimentary: clastic, organic (biological), thiab tshuaj.
hom sediment yog dab tsi?
1) Terrigenous Sediments: Cov sediments no los ntawm cov teb chaws los ntawm kev yaig, volcanism thiab cua thauj khoom. Cov no yog cov pob zeb ntau tshaj plaws.
