Oolite los yog oolite (qe pob zeb ) yog cov pob zeb sedimentary tsim los ntawm ooids, kheej kheej cov nplej uas muaj cov txheej txheem concentric. Lub npe muab los ntawm Ancient Greek lo lus ?όν rau qe. nruj me ntsis, oolis muaj ooids ntawm 0.25-2 millimeters 'inch; pob zeb uas muaj ooids loj dua 2 hli yog hu ua pisolites.

Ntawm no, Oolitic limestone tsim li cas?

Oolitic limestone yog tsim los ntawm me me spheres hu ua ooiliths uas tau daig ua ke los ntawm cov av nkos. Lawv tsim thaum calcium carbonate tso rau saum npoo ntawm cov xuab zeb dov (los ntawm nthwv dej) nyob ib puag ncig ntawm ntug hiav txwv ntiav.

Kuj Paub, Ooids yog dab tsi? Ooids me me (feem ntau ≦2 hli inch), spheroidal, "coated" (txheej) sedimentary nplej, feem ntau muaj li ntawm calcium carbonate, tab sis qee zaum ua nce ntawm cov hlau- lossis phosphate-based minerals.

Puas yog Oolites Biogenous?

Oolite yog ib pob zeb sedimentary ua los ntawm ooliths (ooliths) uas yog cemented ua ke. Feem ntau oolis yog limestones - ooids yog ua los ntawm calcium carbonate (minerals aragonite los yog calcite).

Dab tsi yog cov yam ntxwv ntawm Oolitic limestone?

Cov nplej ntawm cov xuab zeb los yog cov seem ntawm seashell yog dov nyob ib ncig ntawm lub hiav txwv pem teb thiab raws li lawv ua, lawv sau calcium carbonate (CaCO3). Cov khaubncaws sab nraud povtseg yog tsim thiab cov no muab lub pob zeb nws tus yam ntxwv "qe pob zeb" zoo li, raws li lub pob zeb saum npoo zoo li ntses roe (ntses qe). Li no lub sij hawm oolitic limestone.
