Turbidites Whose Sole Markings Show More than One Trend: A Further Interpretation

The presence of sole markings on a single turbidite bed indicating two or more directions of current flow is explained in a new way. The shale surface of which the turbidite sole is a cast may have been exposed and covered more than once through repeated deposition and erosion by turbidity currents moving in different directions. Repeated exposure is likely, since the shale was probably more resistant to such erosion than the turbidite layers which temporarily covered it.
