Cov khoom no yog cemented ua ke thiab hardened los ua cov pob zeb sedimentary hu ua conglomerate, sandstone, siltstone, shale los yog claystone, thiab av nkos. … Ntsev nyob ib ncig ntawm lub pas dej ntsev thiab limestone los ntawm hiav txwv hauv qab yog cov piv txwv ntawm cov pob zeb chemical sedimentary.
hom pob zeb sedimentary yog av nkos?
Mudstone yog pob zeb zoo heev sedimentarymuaj cov av nplaum sib xyaw thiab cov khoom me me.
Puas yog av nkos yog cov tshuaj lom neeg lossis cov pob zeb organic sedimentary?
Sediment keeb kwm:
Piv txwv suav nrog: conglomerate, sandstone, mudstone & shale. Organic sediments yog, raws li lub npe qhia, tsim loj los yog tag nrho ntawm sediment generated los ntawm cov kab mob nyob (e.g. plhaub los yog cov khoom cog). Cov pob zeb uas tshwm sim muaj xws li ntau limestones (piv txwv li limestone, chalk); thiab kuj thee.
Puas yog av nkos yog tshuaj?
Cov Khoom Siv Tshuaj:
Mudstone muaj cov ntsiab lus sib txawv, xws li Feldspar, Micas, Pyrite, Quartz Biotite, Chlorite, Plagioclase, Muscovite lossis Illites, thiab lwm yam. Cov tshuaj lom neeg cov ntsiab lus ntawm av nkos yog Aluminium Oxide, NaCl, CaO, Hlau (III) Oxide, Silicon Dioxide, thiab lwm yam
Puas yog chert a chemical sedimentary pob zeb?
Chert. … Chert tuaj yeem yog a tshuaj lom neeg pob zeb, feem ntau tsim ua cov txaj hauv limestone (Daim duab 9.14), lossis raws li cov lo ntsiab muag tsis tu ncua lossis blobs (nodules). Nws tuaj yeem yog biochemical. Qee cov kab mob me me hauv hiav txwv (piv txwv li, diatoms thiab radiolaria) ua lawv cov kev sim los ntawm silica.
