We have a bunch of pics and have the options of: oomicrite, oosparite, pelmicrite, pelsparite, biosparite, biolithite, and biomicrite. I can't figure out these three. I really thought they were all ooids but there's only two that could be ooids.

The limestones are usually bio-intra-pelmicrite wackestones and packstones, locally bio/intramicrosparite and sparite grainstones. Detrital fine- to coarse-grained quartz is present in variable amounts. Above, a ∼2 m thick interval is composed of marl at the base topped by ferruginous microbially-laminated limestone, overlain by marls ...The upper part of the sequence consists of dolomitized terrigenous pelmicrite and associated lenticular cross-stratified bioclastic grainstones interpreted as tidal flat and tidal channel deposits. In the third cycle, the limestones unit has a very marked shoaling upward character. The lower part of the sequence comprises bioturbated and ...For example, a limestone comprising pellets in a mud matrix is called a ‘pelmicrite’, and a limestone comprising shell fragments with a sparry calcite cement is a *‘biosparite’. It is possible to combine the prefixes of several allochems where appropriate, e.g. ‘oobiosparite’.Upper Oligocene-Lower Miocene time interval is represented by Kurtulmustepe Formation comprising gray coloured claystone and marl alternation with clayey limestones and bedded pelmicrite.

Significant volumes of rock are in the process of being converted to biomicrite and pelmicrite by massive biological erosion and cementation by Mg-calcite micritic cement. Many rocks also display textures similar to some attributed to recrystallization or replacement in ancient limestones.Allochems: term introduced by Folk (1965) for carbonate particles that have formed by chemical or biochemical precipitation. The main groupsare fossil fragments, ooids, pellets, intraclasts. Allochthonous: refers to carbonate particles that formed outside the basin of deposition (implies substantial transport).Sample sentences with "pelmicrite" Declension Stem Carbonate rocks that contain fine-grained calcite in addition to allochems are named intramicrite, oomicrite, biomicrite or pelmicrite under the Folk classification depending on the dominant allochem.Limestones are divisible into eleven basic types, which are relatively easy to recognize both in the laboratory and in the field.
