Compaction Of Winnipegosis Reefs

Abstract

Winnipegosis reefs in southern Saskatchewan are typically encased in the thick incompressible salts of the Prairie Evaporite. These reefs are characterized by raised rims and reverse drape along the top of the salt. Both features are primarily due to post depositional compaction and are clearly visible on seismic data. The rims developed principally as a result of compaction within the reef; the structural low at the Prairie Evaporite level is attributed to differential compaction between the reef and the encasing salt. If these salts are effectively incompressible, then the rim and lagoonal facies are estimated to have been compacted by at least 30 and 44 percent respectively.
