Calculations Based on confined compression tests carried out with lime mud indicate that compaction of this material may produce secondary dips of 60 degrees or more in overlying beds if the material surrounds a relatively incompressible core whose slopes are as steep as 75 degrees . The secondary dips are of course gentler if the slopes of the core are less steep. A comparison of the data for the lime mud with similar data for a lean and for a fat clay, and with the observed void ratios of deeply buried shale, indicates that the compaction of this lime mud may be at least as great as that of a lean clay, and possibly as great as that of a medium clay.
