Strasser, A., (1986): Ooids in Purbeck limestones (Lowermost Cretaceous) of the Swiss and French Jura.
Intra ooid grainstone sub microfacies represent deposition in high-energy conditions prevailing during storms.7.
On the basis of high percentage of ooids, bioclasts and intraclasts this sub-microfacies indicate deposition on a barrier shoal.
They described the Type 2 mounds associated with high-energy ooid and skeletal/ooid shoal complexes, where they formed as "isolatedpatch reefs or laterally continuos biostromal bodies in rather restricted back-shoal settings".
--A lower interval (levels 7-9) formed by red-coloured fossiliferous micritic, bioclastic wackestone, containing sparse small iron ooids and Callovian ammonites characterising the Gracilis Biozone (levels 7-8) and perhaps, lower Anceps Biozone (level 9).
The majority of allochems in the matrix are made up of micritised ooids and peloids forming a poorly sorted assemblage of medium to coarse sand grade matrix (Fig, 10B, 10C), Other minor allochems consist of superficial ooids, coated, disarticulated and abraded shell fragments.
This limestone is principally composed of ooids, carbonate spheres that usually form in tropical beach environments, illustrated by the cross section shown in Figure 3a.

The paleohigh formed by the top of the ooid shoal was colonized by rugose corals, stalked echinoderms, and fenestrate bryozoans.
2:00 POROSITY LOSS, FLUID FLOW, AND MASS TRANSFER IN OOID GRAINSTONE RESERVOIRS OF THE SMACKOVER FORMATION, MISSISSIPPI
In the subsurface of West Texas, the Fusselman Formation comprises a complex series of carbonate facies, including light-colored ooid grainstones, green glauconitic and pink pelmatozoan grainstones and packstones, and sparse skeletal wackestones with minor shaly intercalations.
