The striking meniscus cements are related to evaporation of freshwater charged with dissolved aragonite within these aeolianites. These grains formed on an exposed carbonate shelf and were transported by the wind to their current postion. These aragonite ooids have thin concentric layering of cortex about micritized pelloid nulceae (some after ooids). Botryoidal grains are transported grapestones that form nucleae and are enclosed by aragonite ooid coating. Darkened spots within ooid layers are cyanobacteria colonies that cause local micritization.
