Oolitic limestone texture
Apr 19, 2023 · Color The color of oolitic limestone can range from white to shades of gray, yellow, or brown, depending on the specific composition and the presence of other minerals or organic material. Iron oxides or other impurities may cause reddish or orange coloration in some instances. Uses of Oolitic Limestone Limestone: Limestone is typically formed by the accumulation of calcite or aragonite over a while. Calcite is produced by the precipitation of calcium carbonate while aragonite is made up of calcium carbonate and magnesium carbonate.Oolite is a sedimentary rock, most often limestone, composed of smoothly laminated, spherical to ellipsoidal coated grains that are cemented together ( Figure O16 ). The grain components of oolite are …
