Abstract

In the general section of the coal measures of Iowa, Missouri and Kansas there are two unconformities which are really quite notable in our stratigraphy. One of these, the one at the base of coal measures, receives wide consideration from earliest days, albeit its sedimental equivalency and time-expression is little regarded. That there is another unconformity within the Carbonic section, hardly less notable than the first one mentioned, at the base of the Bethany limestones bevelling all the productive coal section is a very much more recent realization.
