|Paluxy Sandstone, East Texas Basin
The depth map is derived from a structure map of the top of the Paluxy sand (Core Laboratories, 1972). This map also shows the effect of salt structures on the Paluxy Formation. We then used a DEM generated from Digital Terrain Elevation Data (National Imagery and Mapping Agency, 2000) to calculate and grid the depth to top formation (c1paluxyg).
