HANSON AGGREGATES SERVTEX QUARRY

Abstract:  Hanson owns and operates a limestone quarry in Comal County, Texas (figs. 12 and 13). Hanson (Gifford-Hill & Company) acquired the operations in 1977 from Servtex Materials Company. Prior history of the site includes two local New Braunfels, Texas, citizens, Ogden and Eikel, who started the quarry circa 1936. Most of the property is within the city limits of the City of Garden Ridge. Garden Ridge did not incorporate until 1970, and few homes existed in the area at that time. Servtex Quarry is situated on approximately 3,000 acres of land owned in fee by Hanson. The rock quarried at the location, limestone from the Edwards Group, Person Formation, is Early Cretaceous in age. The quarry is located in the Southeastern Balcones Escarpment, within and north of the Balcones Fault Zone. The limestones were deposited in the Cretaceous sea, within and northwest of a bioclastic belt known as the Stuart City Reef, which consisted of rudists and coral and algal debris. Deposition of limestones north and west of the Stuart City Reef created current resources being mined at Servtex Quarry. The current surface exposure of Edwards-age limestones north and west of the Balcones Fault Zone is called the Edwards Plateau.
