Khoom muag: Limestone , ib lub pob zeb sedimentary uas yog dominantly tsim ntawm calcium-cov kabmob carbonate minerals calcite thiab dolomite. Calcite yog tshuaj calcium carbonate (formula CaCO3). Dolomite yog tshuaj calcium-magnesium carbonate (formula CaMg (CO3) 2).

Hauv qhov no, dab tsi yog qhov sib xyaw ntawm limestone?

Limestone yog carbonate sedimentary pob zeb uas feem ntau tsim los ntawm cov pob txha tawg ntawm cov kab mob hauv hiav txwv xws li coral, foraminifera, thiab molluscs. Nws cov ntaub ntawv tseem ceeb yog cov zaub mov calcite thiab aragonite, uas yog cov ntaub ntawv sib txawv ntawm calcium carbonate (CaCO.3).

Ib yam li ntawd, dab tsi yog limestone keeb lossis compound? Limestone yog a compound Calcium carbonate, CaCO3. Limestone yog a compound Calcium carbonate, CaCO3. Tseeb, nws tshwm sim lawm, txheeb xyuas raws li ib tug ntxhia, uas nyob rau hauv crystalline daim ntawv hu ua calcite.

Ib yam li ntawd, nws raug nug, dab tsi yog cov tshuaj lom neeg ntawm limestone?

Limestone

  • Limestone yog pob zeb sedimentary xws li ntau dua 50% calcium carbonate (calcite - CaCO3).
  • Xim: Nws tuaj yeem yog daj, dawb, lossis grey.
  • Tshuaj muaj pes tsawg leeg: Calcite.
  • Kev ntxhib los mos - Clastic lossis Non-Clastic.
