Texas Stadium, the now-demolished former home of the Dallas Cowboys in Irving. Irving was founded in 1903 by J.O. Otto Schulze and Otis Brown. It is believed that literary author Washington Irving was a favorite of Netta Barcus Brown, and consequently the name of the town site, Irving, was chosen.
Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call mud. This composition places shale in a category of sedimentary rocks known as mudstones. Shale is distinguished from other mudstones because it is fissile and laminated.
Petroleum (noun). rock oil, mineral oil, or natural oil, a dark brown or greenish inflammable liquid, which, at certain points, exists in the upper strata of the earth, from whence it is pumped, or forced by pressure of the gas attending it.
