Chemical sedimentary pob zeb daim ntawv los ntawm nag lossis daus ntawm minerals los ntawm dej. Dej nag yog thaum cov khoom yaj tawm los ntawm dej. Piv txwv li: Nqa ib khob dej thiab ncuav ib co ntsev (halite) rau hauv nws. Qhov no yog ib txoj kev zoo rau chemical sedimentary pob zeb rau daim ntawv thiab cov pob zeb yog feem ntau hu ua evaporites.
Kuj kom paub yog, qhov twg yog cov tshuaj sedimentary pob zeb tsim?
Tshuaj thiab Biochemical Sedimentary pob zeb Chemical sedimentary pob zeb yog tsim Thaum cov minerals, yaj nyob rau hauv dej, pib precipitate tawm ntawm kev daws thiab tso rau ntawm lub hauv paus ntawm lub cev dej.
Qhov thib ob, dab tsi yog qee qhov piv txwv ntawm cov pob zeb sedimentary? Tshuaj Cov hom pob zeb sedimentary feem ntau tshwm sim hauv thaj chaw arid; zoo li gypsum thiab ntsev deposits. Piv txwv ntawm chemical sedimentary pob zeb yog: chert , dolomites, flint, pob zeb ntsev, hlau ore thiab qee hom limestone.
Nyob rau hauv no txoj kev, dab tsi yog ib tug tshuaj sedimentary pob zeb?
Chemical sedimentary pob zeb Cov ntaub ntawv thaum cov ntxhia cov ntsiab lus hauv cov tshuaj ua supersaturated thiab inorganically precipitate. Feem ntau chemical sedimentary pob zeb suav nrog oolitic limestone thiab pob zeb muaj li ntawm evaporite minerals, xws li halite ( pob zeb ntsev), sylvite, baryte thiab gypsum.
Ob hom pob zeb sedimentary yog dab tsi?
Sedimentary pob zeb yog tsim los ntawm tsub zuj zuj ntawm sediments. Muaj peb hom pob zeb sedimentary. Clastic sedimentary pob zeb xws li breccia , koom nrog , xuab zeb , siltstone , thiab shale yog tsim los ntawm mechanical weathering khib nyiab.

Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
Yuav ua li cas detrital sedimentary pob zeb tsim?
Detrital sedimentary pob zeb, tseem hu ua clastic sedimentary pob zeb, yog tsim los ntawm cov pob zeb tawg uas tau raug huab cua los ntawm cov pob zeb uas twb muaj lawm. Cov nplej ntawm sediments yog dab tsi tau cemented ua ke los tsim cov pob zeb sedimentary. Yog li ntawd, yog tias koj muaj av nplaum-loj nplej cemented ua ke, koj yuav tau txais shale
Puas yog pob zeb av nplaum yog pob zeb sedimentary?
Boulder Clay. Boulder av nplaum los ntawm Yorkshire, UK los ntawm lub sij hawm Pleistocene, qhia random loj ntau yam clasts nyob rau hauv ib tug glacial av nplaum matrix. Tsim los ntawm ntau yam txheej txheem glacial lossis dej khov, cov pob zeb sedimentary no muaj ntau qhov ntau thiab tsawg
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
Cov pob zeb hauv av twg tuaj yeem tsim cov pob zeb zoo li lub raum?
Hematite (los yog haematite) Kuj tseem muaj ntau hom hematite, qee yam yog: raum ore, ib qho loj, botryoidal (lumpy) lossis reniform (lub raum zoo li tus) daim ntawv; specularite, micaceous (flaky) daim ntawv; oolitic, ib daim ntawv sedimentary tsim los ntawm cov nplej me me; liab ochre, ib daim ntawv liab earthy
