Browsing: Concrete roads

An entry at www.sciencedirect says, “Extensive tar sands with reserves of about 41 billion barrels of oil are known to occur in Cretaceous terrigenous sediments in Ondo and Ogun states. The hydrocarbon occurs in two predominantly sandy zones separated by an eight-metre thick oil shale.”
