We classify salt-related faults and fault welds in the northern Gulf of Mexico on the basis of the three-dimensional geometry of the faults, welds, deformed strata, and associated salt bodies. Kinematic or genetic criteria are not used in the classification, although we comment on these aspects where they are helpful.

Use of groundwater-flow models for prediction of future availability of water resources is standard practice. Having accurate hydraulic parameters for input into groundwater-flow models is critical to the generation of realistic local and regional water-resource management plans.

Beautifully illustrated by more than 100 photos and diagrams, this nontechnical guide surveys the geologic evolution of Mustang Island and the relationship between physical setting and biologic environments along the Texas coast.

The former Director of the Bureau of Economic Geology from 1960 through 1970, Dr. Flawn recalls his early days in the field in West Texas, his dealings with the Department of Geological Sciences at The University of Texas at Austin, his decade as Bureau Director, and his various consulting activities during this time.
