Oolitic limestone texture.
A porous sand or sandstone that contains asphalt or bitumen within its pore spaces. Sometimes the name "oil sand" is used for a deposit in which the hydrocarbon is in a liquid form and the name "tar sand" is reserved for those deposits in which the hydrocarbon is in the form of solid asphalt or bitumen.

In the unbroken examples the oolite just looks like a tiny ...Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite ). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate.
