Salt in the Ochoa Series, New Mexico and Texas (open access)

Salt in the Ochoa Series, New Mexico and Texas

The following report is a synopsis of readily available information on the mineralogy, thickness and areal extent of soluble salt deposits in the Ochoa series of Permian age in southeastern New Mexico and western Texas. It's part of a more extensive investigation of salt being carried out by the U.S. Geological Survey in connection with its Investigation of Geologic Processes project on behalf of the Division of Research, U.S. Atomic Energy Commission.

The Thermal Expansion of NaCl at High Pressures and Temperatures (open access)

The Thermal Expansion of NaCl at High Pressures and Temperatures

Abstract: The thermal expansion of NaCl at high pressures and temperatures is estimated by extrapolating high temperature compressibility data to high pressures using finite strain theory. The thermal expansion is apparently negative at pressures over 50,000 bars at 300°C and at higher pressures at other temperatures.
