Abstract

Selected salt single crystals from core samples of bedded salt from the WIPP site have been tested to determine the rate of migration of their liquid-filled (fluid) inclusions in thermal gradients. Gradients of 1.5°C.cm−1, maintained for periods of 3–10 days, at ambient temperatures of 108°–260°C, resulted in rates of movement of 1.2–5.4 cm.yr −1 for cubic inclusions 1 mm on an edge. Inclusions 0.1 mm on an edge moved only ~30% as fast. Increase in ambient temperature and/or gradient increased the rate, in approximately direct proportion. The migration rate for inclusions in different parts of a given sample, however, may vary by a factor of 3, for unknown reasons, and some other interesting observed phenomena are still unexplained.
