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. Transmissivity, hydraulic conductivity, and storativity are some of the important parameters needed for developing numerical groundwater-flow models.

From 1952 to 1956, Pemex conducted a considerable amount of stratigraphic field work in the eastern Sierra Madre and in Laramide folds to the north across the Sabinas Basin. Special thanks and consideration are extended to Pemex for releasing this classic work, in which 76 stratigraphic sections were measured and described, resulting in this significant internal company report by William E. Humphrey and Teodoro Diaz. The former was initially employed by the consulting firm of DeGolyer and MacNaughton; the latter was employed by Pemex.

"When in the early 1980’s it became known that the Federal Government was planning to undertake the construction of the massive Superconducting Super Collider (SSC) project, scientists in the various states, still without precise information on the criteria to be established for site selection, began to seek ways in which they, and their states, could participate in the project.
