Boulder Clay . Pob zeb av nplaum los ntawm Yorkshire, UK los ntawm lub sijhawm Pleistocene, qhia txog qhov sib txawv ntawm ntau qhov sib txawv hauv cov glacial av nplaum matrix. Tsim los ntawm ntau yam txheej txheem glacial lossis dej khov, cov no sedimentary pob zeb muaj nyob rau hauv ntau qhov ntau thiab tsawg.
Hauv qhov no, puas yog pob zeb av nplaum yog pob zeb mos?
Pob zeb av nplaum yog ib tug geological deposit ntawm av nplaum , feem ntau puv ntawm pob zeb , uas yog tsim tawm hauv av moraine khoom ntawm glaciers thiab ice-daim ntawv. Nws feem ntau yog tawv, tawv av nplaum tsis muaj stratification, tab sis qee cov ntau yam yog txawv laminated.
Tsis tas li ntawd, qhov txawv ntawm pob zeb thiab pob zeb yog dab tsi? Cov qhov sib txawv ntawm pob zeb thiab pob zeb tuaj yeem piav qhia hauv cov ntsiab lus ntawm qhov loj thiab detachment. A pob zeb yog txhais los ntawm geologists raws li ib tug aggregate ntawm minerals. A pob zeb yog hom pob zeb , tshwj xeeb tshaj yog ib tug loj detached ib tug. Tag nrho pob zeb yog pob zeb , tab sis tsis yog tag nrho pob zeb yog pob zeb.
Hais txog qhov no, puas yog boulder av nplaum unconsolidated?
Till, tseem hu ua pob zeb av nplaum , yog mix tsis sib koom sediment nrog ntau yam ntawm grain loj ( av nplaum - pob zeb ). Ntau pob zeb av nplaum yog ntawm ib tug xiav-grey kom txog rau thaum raug huab cua uas ua rau ib tug transformation rau ib tug xim av.
Dab tsi yog qhov mus txog hauv geology?
Txog rau, hauv geology , unsorted khoom tso ncaj qha los ntawm glacial ice thiab qhia tsis stratification. Txog thaum qee zaum hu ua boulder av nplaum vim nws yog cov av nplaum, pob zeb ntawm qhov nruab nrab, lossis sib xyaw ntawm cov no.

Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
Puas yog hlau yog pob zeb lossis pob zeb?
Los yog, cov ntxhia los yog ib qho sib xyaw ntawm cov ntxhia los ntawm cov khoom tseem ceeb, tshwj xeeb tshaj yog cov hlau, tuaj yeem tau txais txiaj ntsig zoo los yog rho tawm yog cov ore. Hlau - Ib qho hlau ntawm ob lossis ntau dua hlau. Yog li ntawd, pob zeb muaj cov zaub mov, uas nyob rau hauv loj concentration yog hu ua ores thiab cov no yog mined rau hlau
Puas muaj cov pob txha pom nyob hauv cov pob zeb sedimentary?
Ntawm peb hom pob zeb loj, fossils feem ntau pom muaj nyob hauv pob zeb sedimentary. Tsis zoo li feem ntau cov pob zeb igneous thiab metamorphic, cov pob zeb sedimentary tsim ntawm qhov kub thiab txias uas tsis rhuav tshem cov pob txha
Puas yog pob zeb av nplaum ntxeem tau?
Cov av nplaum yog scraped los ntawm cov txheej saum toj kawg nkaus ntawm cov pob zeb qub los ntawm kev txav ntawm cov dej khov lossis cov ntawv dej khov. Boulder av nplaum yog chav kawm nrog ib pab pawg ntawm cov khoom tsis zoo, piav qhia los ntawm cov lus tsis yog caj ces diamicton. Nws feem ntau yog ib qho tawv, tawv av nplaum uas tsis muaj stratification, tab sis qee hom yog txawv laminated
