Description

The Carlinville Anticline or Dome, as shown on early maps, is a minor, irregular eastward nosing of contour lines on the Herrin Coal Member (Pennsylvanian). The term "dome" is inappropriate, for none of the maps indicate closure. New structural mapping (Nelson 1987b) that uses many additional well records indicates a series of small irregular rises and depressions on the Herrin Coal in the area of the Carlinville Anticline. No structure worthy of naming is present, and reference to the Carlinville Anticline should be discontinued.
