Chemical 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
Ib yam li ntawd, koj tuaj yeem nug, cov pob zeb chemical sedimentary qhia tau li cas?
Chemical sedimentary pob zeb yog txheeb xyuas los ntawm kev txheeb xyuas cov ntxhia los ntawm lawv yog tsim. Hauv chav kuaj no muaj plaub yam minerals uas yuav tsum muaj txheeb xyuas - quartz, halite, gypsum thiab calcite. Quartz muaj ib tug hardness ntawm 7 thiab yog heev nyuaj rau khawb, txawm nrog ib tug zoo zoo riam hniav.
Tsis tas li ntawd, dab tsi yog hom chemical sedimentary pob zeb? Cov feem ntau chemical sedimentary pob zeb , nyob deb, yog limestone. Lwm tus muaj xws li chert, banded hlau tsim, thiab ntau yam pob zeb uas daim ntawv thaum lub cev ntawm cov dej evaporate. Cov txheej txheem lom neeg yog qhov tseem ceeb hauv kev tsim ntawm qee qhov chemical sedimentary pob zeb , tshwj xeeb tshaj yog limestone thiab chert.
Qhov thib ob, cov pob zeb chemical sedimentary nyob qhov twg?
Chemical sedimentary pob zeb tuaj yeem yog pom nyob rau hauv ntau qhov chaw, los ntawm dej hiav txwv mus rau suab puam mus rau qhov tsua. Piv txwv li, feem ntau limestone tsim nyob hauv qab dej hiav txwv los ntawm nag lossis daus ntawm calcium carbonate thiab cov seem ntawm cov tsiaj hauv hiav txwv nrog cov plhaub.
Lub pob zeb sedimentary twg yog Tshuaj Biochemical?
Limestone

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
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
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
