It is the wave action that rolls the nucleus particles back- and forwards creating the symmetrical aspect of the oolite. The oolite deposits can build massive shoals and offshore bars with foresetting on the shelf (Figure 4.147).

Laudon (1933), in his definitive paper on the Gilmore City Limestone from neighboring Pocahontas County, correlated the Humboldt beds to his uppermost Gilmore CityThe hardness of Oolite is 3-4 whereas its compressive strength is Not Available. Streak is the color of rock when it is crushed or powdered. The streak of Oolite is white whereas its fracture is conchoidal. Luster of Oolite is the interaction of light with the surface of Oolite. Luster of Oolite is pearly to shiny. Oolite cleavage is non-existent.
