T. C. Buschbach
The Buelter Member of the Ironton Sandstone (Buschbach, 1964, p. 36).
Named for Buelter School, Kane County.
The type section of the Buelter Member is located 2 miles west of Buelter School, Kane County, and is at a depth of 1180-1230 feet in Batavia city well No. 3 (SE SW NE 22, 39N-8E) (sample set 6901).
The Buelter Member is the basal member of the Ironton Sandstone.
Extent and thickness
It is widely present in northern Illinois, where it is 20-80 feet thick.
It is dominantly medium-grained, moderately well sorted, rarely dolomitic sandstone. The contact with the underlying fine-grained, well sorted sandstone of the Galesville is generally sharp.
