Folk Classification	Well sorted quartzose radial and concentric ooids
Dunham Classification	Well sorted quartzose radial and concentric ooids
Common Grains	Ooids, peloids &quartz
Sorting	Well sorted
Rounding	Well rounded
Micritization & envelopes	A few coated grains and peloids
Cement & diagenetic fabric	Radial calcite and concentric aragonite cortex layers about pellet, broken ooid and quartz nuleae

Diagenetic history	Both calcite and aragonite layers collecting on ooid nucleae

Striking high energy ooid grains forming on the south western shore of Great Salt Lake in the vicinity of the northern end of Antelope Island. Note the mix of radial calcitic coats and concentric aragonite coats about the nuceleae.
