Detrital sedimentary pob zeb , kuj hu ua clastic sedimentary pob zeb , yog muaj li ntawm pob zeb fragments uas tau weathered los ntawm pre-existed pob zeb . Cov nplej no ntawm sediments yog dab tsi tau cemented ua ke tsim cov pob zeb sedimentary . Yog li yog tias koj muaj av nplaum-loj nplej cemented ua ke, koj yuav tau shale.
Ib sab ntawm no, dab tsi yog 3 txoj kev sedimentary pob zeb tuaj yeem tsim?
Sedimentary pob zeb, uas yog tsim los ntawm sediments ntawm lwm cov pob zeb thiab cov ntaub ntawv, tsim los ntawm ntau txoj kev. Cov txheej txheem no suav nrog yas sedimentation, chemical sedimentation thiab biochemical sedimentation.
Kuj Paub, qhov luaj li cas ntawm cov pob zeb detrital sedimentary yog dab tsi? Detrital Sedimentary Pob Zeb Detritus yog cais los ntawm nws nplej loj . Cov nplej loj dua 2 millimeters hu ua gravel. Cov nplej ntawm 1/16 hli thiab 2 hli yog hu ua xuab zeb. Cov nplej me dua 1/16 mm yog nyob rau hauv cov av nplaum thiab av nplaum qhov loj ranges, feem ntau hu ua av nkos.
Dab tsi yog qhov txawv ntawm qhov detrital thiab tshuaj lom pob zeb sedimentary tsim?
Detrital sedimentary pob zeb yog pob zeb ua los ntawm pre-existed pob zeb los yog khib nyiab. lawv yog ua los ntawm clasts los yog pob zeb tawg tawg. Chemical sedimentary pob zeb yog tsim los ntawm evaporation los yog nag lossis daus ntawm cov dej uas nplua nuj nyob rau hauv minerals.
Dab tsi yog cov khoom ntawm detrital sedimentary pob zeb?
Detrital sedimentary pob zeb yog cov uas cov khoom tau raug thauj raws li cov khoom siv. Cov khoom lawv tus kheej tuaj yeem tau txais los ntawm huab cua huab cua lossis tshuaj huab cua. Sedimentation txhais tau hais tias nyob ntawm cov kua, dej los yog huab cua.

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"
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
Yuav ua li cas chemical sedimentary pob zeb tsim?
Chemical sedimentary pob zeb tsim los ntawm nag lossis daus ntawm cov zaub mov los ntawm dej. Cov 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 hauv kev zoo rau cov pob zeb sedimentary los tsim thiab cov pob zeb feem ntau hu ua evaporites
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
