Mudrocks yog chav kawm ntawm cov nplua-grained siliciclastic sedimentary pob zeb. Ntau hom mudrocks muaj xws li siltstone, claystone, av nkos, slate, thiab shale. Feem ntau ntawm cov khoom uas lub pob zeb tsim muaj tsawg dua 1⁄16 hli (0.0625 mm; 0.00246 nyob rau hauv) thiab me me dhau los kawm tau yooj yim hauv thaj teb.
Lub ntsiab lus ntawm Mudrock yog dab tsi?
Mudrock txhais tau tias yog ib nplua-raug zoo- grained, siliciclastic sediment los yog sedimentary pob zeb. Quantita- tiv thaiv ciam teb rau pawg pob zeb no yog npaj siv cov ntsiab lus ntawm cov av thiab pob zeb ntsuas qhov ntsuas, ntawm kev hloov pauv ntawm cov khoom siv lossis cov khoom siv.
Mudrock tsim li cas?
Mudrocks yog pob zeb tsim feem ntau ntawm cov av mus rau av nplaum-loj clasts. Fine-grained quartz thiab feldspars thiab ntau npaum li cas ntawm carbonates, sulfides, hlau oxides, hnyav minerals, thiab organic carbon yuav muaj nyob rau hauv me me Cheebtsam.
pob zeb claystone yog dab tsi?
Los ntawm txhais, claystone yog a hom pob zeb sedimentary. Nws tseem ceeb muaj cov khoom zoo uas tsawg dua 1/256mm loj, uas yog cemented rau hauv cov pob zeb tawv. Feem ntau, tib neeg siv av nkos, siltstone / shales, thiab claystone cov ntsiab lus sib hloov. Txawm li cas los xij, txhua yam yog qhov sib txawv ntawm geology foundations.
pos nphuab hu ua dab tsi?
