<p><span>Thick </span>salt<span> </span>deposits<span> are present in the Middle Pennsylvanian </span>Paradox<span> Member of the Hermosa Formation in the </span>Paradox<span> </span>Basin<span> of </span>southeast<span> </span>Utah<span> and </span>southwest<span> </span>Colorado<span>. Data suggest that the original thickness of these </span>deposits<span> was from 5000-6000 feet. Locally, however, these </span>deposits<span> have been subjected to intense deformation and flow, resulting in thicknesses as great as 14,000 feet. Each </span>salt<span> bed is part of a series of partial and complete evaporite cycles which show a lateral and vertical change in facies. Varve counts in the </span>salt<span> beds give an indication of deposition rates of time-equivalent carbonate beds. Black sapropelic shales are interbedded with the </span>salt<span> beds. It appears that the euxinic environment in which the shales were deposited persisted during the deposition of </span>salt<span>. An understanding of the stratigraphy of the </span>salt<span> </span>deposits<span> has made possible a more complete depiction of early tectonic events involving the </span>salt<span> </span>basin<span>. These studies indicate that many of the </span>salt<span> anticlines in the </span>basin<span> were formed along trends of originally thick </span>salt<span> beds, and that upward growth of these anticlines possibly began during the late stages of </span>salt<span> deposition.</span></p>
