Micrite yog limestone constituent tsim los ntawm calcareous hais nyob rau hauv txoj kab uas hla mus txog plaub Μm tsim los ntawm recrystallization ntawm txiv qaub av nkos. Micrite yog txiv qaub av, carbonate ntawm av nkos qib. Nyob rau hauv Folk classification microite yog lub pob zeb carbonate dominated los ntawm nplua-grained calcite.

Piv txwv li, dab tsi minerals nyob rau hauv Micrite?

Micrite = txiv qaub av ; CaCO3, cov ntxhia calcite . Micrite yog qhov sib npaug ntawm av nplaum (pob zeb = shale) hauv clastics. Keeb kwm deposited li microscopic aragonite koob, tab sis tam sim no hloov mus rau calcite thiab tom qab ntawd calcite cemented los ua lub pob zeb. Saib Keeb Kwm ntawm Micrite kom paub meej ntxiv.

Tsis tas li ntawd, Micrite sedimentary pob zeb yog dab tsi? Micrite , sedimentary pob zeb tsim los ntawm calcareous hais nyob rau hauv txoj kab uas hla ntawm 0.06 mus rau 2 hli (0.002 mus rau 0.08 nti) uas tau muab tso rau mechanically es tsis yog los ntawm kev daws. Thaum tsim yuav luag tag nrho cov plhaub khib nyiab, lub pob zeb hu ua coquina (q.v.). Coquinite yog qhov sib npaug sib npaug.

Yog li ntawd, yog Coquina clastic los yog tshuaj?

Coquina . Coquina yog ib tug detrital limestone uas muaj cov plhaub los yog plhaub tawg. Cov khoom pov thawj yog mechanically sorted (feem ntau yog los ntawm hiav txwv yoj), thauj thiab feem ntau abraded vim kev thauj thiab sorting. Nws yog ib qho ntxeem tau thiab mos tsis muaj zog rau nruab nrab cemented pob zeb.

Puas yog travertine clastic?

Clastic sediments tuaj yeem muab tau los ntawm txhua hom pob zeb, suav nrog cov pob zeb uas nyob hauv qhov tsua thiab tawm sab nraud ntawm lub qhov tsua (Fig. 1), nrog rau cov pob zeb thib ob xws li travertine . Clastic sediments yog volumetricically feem ntau deposits nyob rau hauv qhov tsua.
