Limestone Stair Kauj Ruam

Limestoneis yog ib lub pob zeb uas muaj carbonate sedimentary uas feem ntau yog cov pob txha pob txha tawg ntawm cov tsiaj txhu hauv hiav txwv xws li coral, foraminifera, thiab molluscs. Nws cov ntaub ntawv tseem ceeb yog cov zaub mov calcite thiab aragonite, uas yog qhov sib txawv cov qauv siv lead ua ntawm calcium carbonate (CaCO₃).

Limestone-Ua Rau Ib puag ncig: Tubrog nkoj

Feem ntau cov limestones tsim nyob hauv qhov dej ntiav, nqig, sov dej hiav txwv. Hom kev tiv thaiv ib puag ncig no yog qhov chaw cov tsiaj muaj peev xwm tsim cov plhaub calcium carbonate thiab cov pob txha yooj yim tuaj yeem muab cov khoom xav tau los ntawm dej hiav txwv. Thaum cov tsiaj no tuag, lawv lub plhaub thiab cov pob txha pob txha tawg ua ib lub sediment uas tej zaum yuav tau muab pov rau hauv pob zeb. Lawv cov khoom siv pov tseg tuaj yeem tuaj yeem koom nrog qhov loj hauv av. Limestones tsim los ntawm hom kev cog lus no yog cov av pob zeb roj. Lawv keeb kwm roj ntsha feem ntau tshwm sim hauv cov pob zeb los ntawm kev muaj pob txha.

Qee qhov limestones tuaj yeem tsim los ntawm kev los nag ntau ntawm calcium carbonate los ntawm hiav txwv lossis dej ntshiab. Limestones tsim ua txoj kev no yog tshuaj lom neeg pob zeb. Lawv xav hais tias yuav tsis tshua muaj kev vam meej ntau dua li limestones.
