clastic sedimentary pob zeb
Ib yam li ntawd, nws yog nug, hom pob zeb sedimentary yog limestone?
Limestone. Limestone yog cov pob zeb sedimentary uas muaj calcium carbonate (ntau tshaj 50%). Nws yog cov feem ntau uas tsis yog-siliciclastic ( xuab zeb thiab shale yog cov pob zeb uas muaj siliciclastic) sedimentary pob zeb. Limestones yog pob zeb uas muaj feem ntau ntawm calcium carbonate (minerals calcite lossis aragonite).
Kuj Paub, dab tsi yog cov pob zeb clastic sedimentary? Clastic sedimentary pob zeb yog ua los ntawm tej daim (clasts) uas muaj ua ntej pob zeb . Tej daim pob zeb yog loosened los ntawm huab cua, ces thauj mus rau ib co phiab los yog kev nyuaj siab qhov twg sediment yog daig. Yog tias sediment yog faus tob, nws ua compacted thiab cemented, sib sau sedimentary pob zeb.
Yog li ntawd, dab tsi yog siltstone siv rau?
Siltstone muaj tsawg heev siv. Nws tsis tshua muaj lub hom phiaj ntawm kev tsuas yog siv los ua cov khoom siv los yog kev tsim khoom noj. Lub intergranular pore qhov chaw nyob rau hauv siltstone me me heev rau nws los ua ib tug zoo aquifer. Nws tsis tshua muaj qhov ntxeem tau txaus los yog dav txaus los ua cov roj lossis roj reservoir.
Yuav ua li cas koj txheeb xyuas siltstone?
Silt zoo li tsis yog cohesive, nonplastic, tab sis tuaj yeem ua liquefy yooj yim. Ib qho kev sim yooj yim rau txiav txim seb puas yog pob zeb a siltstone yog muab lub pob zeb rau ib tug hniav. Yog tias lub pob zeb xav tias "gritty" tawm tsam ib tus hniav, ces nws yog siltstone.

Kev piav qhia: Txoj cai ntawm kev txiav hlais yog qhov kev xav tias lub magma protrusion uas txiav los ntawm kab rov tav txheej ntawm kab pheeb ces kaum los yog ntsug yog me dua cov txheej uas nws txiav. Sedimentary pob zeb feem ntau pom nyob rau hauv kab rov tav los yog ze kab rov tav txheej los yog strata
Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
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
