Exempel på hur man kan använda OOIDS i en mening

• Pisoids are similar to ooids, but are larger than 2 mm in diameter, often considerably larger, as with the pisoids in the hot springs at Carlsbad (Karlovy Vary) in the Czech Republic.
• Examples would include ooids, peloids, oncolites, pellets, fossil or pre-existing carbonate fragments.
• Long (1993) recognises three lithofacies in the Burgsvik beds; a poorly exposed silty/sandy mudstone facies dominant in the lower beds, appearing as interbeds in the middle beds; a fine to very fine sandstone; and a "biofacies" consisting of ooids, oncolites and bioclasts.
• The most significant geological and biological effects of calcite sea conditions include rapid and widespread formation of carbonate hardgrounds, calcitic ooids, calcite cements, and the contemporaneous dissolution of aragonite shells in shallow warm seas.
• The ooids (on average) comprise ~33% siderite, ~33% berthierine, and a similar proportion of ancillary minerals and demonstrate deformation whilst the sediment was still plastic.
• As a result, peloids not only include possible pellets, but also include a variety of other distinctly non-pellet grains—such as indistinct intraclasts, micritized ooids, or fossil fragments.
• The last section, latest Raricostatum subzone, there were a series marine transgressive surfaces, linked with the called Pli1 transgressive phase, known thanks to molluscs and ooids, along with an increase of marine macrofauna and microfauna.
• Marine carbonate ooids are formed in warm, supersaturated, shallow, highly agitated marine water intertidal environments, and their presence in geological records provides a key role in paleoclimatic and paleogeographic reconstructions.
