About This Publication
This map is one of several 1:24,000-scale maps of the region north of the Llano Uplift, focusing on sand resources in the Cambrian and Ordovician stratigraphy of Central Texas. Maps for this region provide a basic geologic framework to aid in managing water and earth resources; planning land use; identifying aquifer recharge areas; and identifying sources of dimension stone, aggregate, construction sand and specialty sand, gravel, and other earth resources. This study area lies within the eolian to near-shore setting of the Cambrian-age Hickory Formation, transitional to the marine-transgressional Tanyard Formation and Cretaceous limestones. The Hickory Formation is an important sand resource in Central Texas, and the Hickory aquifer recharge zone is important for water resource management in the region.
