Seismotectonic maps in the vicinity of the lower Wabash Valley, Illinois, Indiana, and Kentucky - Digital Spatial Database: Depth to magnetic rocks

Metadata Updated: November 12, 2020

The structure of and depth to the floor of the Mississippi Valley and Rough Creel Grabens and surrounding regions were interpreted from aeromagnetic data. This cover contains the depth contours for the region within this study area and was clipped from the larger cover. This cover was not plotted in the Wabash Valley map series, but is included for those users who are interested in comparing the depth to basement from geologic data (bcontours and bfaults) to the depth to magnetic rocks (usually basement) from geophysical data. Depth units in this cover are kilometers below sea level, whereas depth units in bcontours are in thousands of feet below sea level.
