b) OOLITIC LIMESTONE - white, round pellet-sized concretions of calcite formed by wave turbulence in shallow, warm marine water. DOLOMITE - limestone altered by seawater becomes "enriched" in magnesium: has a composition of(Ca,Mg)(CO3)2; dolomite is important because it has "high porosity"; make good oil & gas reservoirs:~50% of the oil in the ....

Oolitic limestone: Oolitic limestone is known to be a calcite cemented calcareous stone, consisting shell fragments which are non-crystalline in character. oolitic limestones can adjust to temperature changes without having any cleavage and keep an extremely uniform in composition and texture.Oolitic Limestone Oolites (or ooliths) are small, sand-size clasts of calcium carbonate with a spherical to ovate shape. They form by the concentric accumulation of calcium carbonate layers around a nucleus that might …
