Seismic Data-Processing Techniques in Exploration for Reefs, Northern Michigan1
Published:January 01, 1977
Abstract Difficulty in detecting reefs in northern Michigan is caused mainly by noise, “multiples” (reverberations), variations in topography, and variations in thickness of weathered material and glacial drift. During the last three years new data-processing techniques—such as automatic statics and deconvolution, and relative-amplitude processing methods—have led to improved detection of reefs. Quality of information from seismic sections is enhanced further as data-processing geo-physicists gain experience in the areas of activity. Communication among data-processing geophys-icists, interpreters, and geologists also is necessary to produce the most reliable picture of subsurface geology in the reef tracts.

Reefs and Evaporites—Concepts and Depositional Models
With the Michigan basin having long been recognized as a classic area for the study of evaporite deposits, most of the papers included in this volume were presented at a 1975 meeting focusing on the Michigan basin. Topics covered include: Depositional environments of pinnacle reefs in the northern shelf of the Michigan basin; Sedimentology and depositional environments of basin-center evaporites; depositional environment in southeastern Michagan; An evaporitic lithofacies continuum; and Reefs and evaporites—a summary.
