Ooids feem ntau tsim nyob rau hauv hiav txwv pem teb, feem ntau yog nyob rau hauv ntiav dej hiav txwv tropical (nyob ib ncig ntawm Bahamas, piv txwv li, los yog hauv Persian Gulf). Tom qab muab faus rau hauv cov pob zeb ntxiv, cov ooid nplej tuaj yeem sib xyaw ua ke los ua cov pob zeb sedimentary hu ua oolite.
Oolites tso rau qhov twg?
Oolitic limestone yog tsim los ntawm cov me me hu ua ooiliths uas tau daig ua ke los ntawm cov av nkos. Lawv tsim thaum calcium carbonate tso rau ntawm saum npoo ntawm cov xuab zeb dov (los ntawm nthwv dej) nyob ib puag ncig ntawm ntug hiav txwv ntiav.
ooids tsim hnub no nyob qhov twg?
Hnub no ooids yuav tsum pom nyob rau hauv ntau qhov chaw uas muaj dej ntiav ntiav, suav nrog Bahamas, Shark Bay hauv Australia, thiab Persian Gulf, tag nrho cov uas yog marine qhov chaw; tiam sis lawv kuj muaj qee zaum pom nyob rau hauv dej hiav txwv xws li Great S alt Lake hauv Utah.
Nyob rau hauv hom twg ua ooids daim ntawv?
Ooids yog sib npaug, cov xuab zeb me me ntawm calcium carbonate uas feem ntau tsim los ntawm mineral nag lossis daus hauv dej hiav txwv sov thiab ntiav Lawv thauj los ntawm nthwv dej thiab dej ntws ua rau cov shoals zoo nkauj thiab Cov xuab zeb dawb, piv txwv li hauv Bahamas 1, 2 (Fig. 1).
pob zeb hom twg muaj ooids?
Oolite yog pob zeb sedimentary ua los ntawm ooids (ooliths) uas yog cemented ua ke.
