Abstract

The San Antonio metro area of south-central Texas illustrates the relationship of geology to landforms, ecosystems, resources and historical development. The metro area is underlain by a variety of sedimentary rock types (limestone, chalk, shale and sandstone) of Cretaceous and Cenozoic age, many of which are juxtaposed by a complex system of normal faults (Balcones fault system). The varied lithologies support different landscapes and ecosystems; the principal carbonate aquifers are guided by faulting and lithology. The availability of soils, earth resources and particularly water formed key controls on Hispanic, German and American settlement and industrial development.

A new publication by the South Texas Geological Society taps the public's fascination with San Antonio history, as well as residents' ongoing concerns about water and landscapes. The full-color, 110-page 5”x9” book contains maps and photographs to connect readers with the historical and geological landscapes of the area. Two driving tours (springs and missions in Bexar County, and Comal County trails) and two walking tours (San Antonio Springs, and downtown San Antonio) highlight the principal features. The writing style is intentionally straightforward and jargon-free.

Programs to use this product to reach out to schools, convention groups, and community venues are being developed.
