Geology of the Eagle Ford Quadrangle, Dallas County, Texas

The Eagle Ford quadrangle includes an area of 62 square miles in western Dallas County. It is bounded by the parallels 32°45\u2700 and 32°52\u2730 N, and by the meridians 96°52\u2730 and 97°00\u2700 W. The towns of Irving and Eagle Ford are in the area, as are portions of Grand Prairie and Arcadia Park. A network of paved highways and graveled roads makes most of the quadrangle readily accessible by automobile. Physiographically, this area is part of the Black Prairie, a province of low relief in which the landscape has been largely shaped by running water. West and Elm forks of the Trinity River, with their tributaries, form a dendritic pattern over the Eagle Ford area
