An introductory chapter briefly reviews Texas' geology followed by a series of road guides with the local particulars. The authors tell you what the rocks are and what they mean. Useful graphics and charts supplement the text and help you to understand

The Geology of Texas is written to accompany introductory courses including physical and historical geology, as well as physical geography, and was designed to compliment the topics of those courses for students in Texas and surrounding regions. The chapter follows the geologic history of Texas from the Precambrian to recent, with illustrations from virtually all parts of the state. Students will see how plate tectonics as well as surficial processes have created the Texas landscape, and how that geologic record influenced the settlement of Texas and the importance of geology to the inhabitants of the region today. A major theme of the chapter is economic geology, with attention to Texas' important energy resources, especially petroleum and coal, and also the vital groundwater sources that will become increasingly important to the regions' growing population. Environmental issues are also stressed, including the impacts of frequent hurricanes and large floods. The series can be bound into any Thomson Brooks/Cole text to create a more compelling regional edition highlighting relevant material.

Geo-Texas succeeds in bringing together astronomy, geology, meteorology, oceanography, and environmental studies in a highly informative, one-of-a-kind guide to Earth sciences in the Lone Star State. Eric R. Swanson draws on the latest scientific findings in treating the natural history of Texas from the oldest known rock, through the age of the dinosaurs, to the geologic present, from the early development of Texas' water and land resources to the current crisis of environmental pollution. In examining Texas natural sciences-and the abiding connection between Texans and their physical surroundings-Geo-Texas is engagingly anecdotal and draws freely on the wry humor with which Texans have always observed and regarded their environment. Entertaining accounts of natural phenomena, such as a meteorite scoring a direct hit on a swimming pool and a Texas twister sweeping up a farmer and returning him to earth unharmed, supplement the scholarship in each chapter to show how cultural and scientific issues converge. Students and teachers of Texas Earth science will find Geo-Texas indispensable. With more than eighty illustrations and valuable appendices listing rock hound clubs, Earth science organizations, and points of interest throughout the state, Geo-Texas will also appeal to the general reader and serve as the Earth science guide for lovers of Texas and its multifaceted environment.
