===Original description===<br />
The Chapel (No. 8) Coal Member of the Modesto Formation (Kosanke et al., 1960, p. 38).<br />
<br />
===Derivation===<br />
Named for Graham Chapel, Peoria County.<br />
<br />
===Other names===<br />
It previously was called Trivoli (No. 8) coal (Wanless, 1931a, p. 181-182, 190, 192).<br />
<br />
===History&#47;background===<br />
The name "No. 8" was first given to this coal by Lesquereux (1866, p. 213) for an exposure near Shawneetown, Gallatin County. Worthen (1870) also applied the name to this coal in outcrops near Springfield, Sangamon County.<br />
<br />
==Type section==<br />
<br />
===Type location===<br />
The type section consists of exposures in a ravine northeast of Pea Ridge School, about 2 miles south of Graham Chapel (SW 3, 8N-5E) (Wanless, 1956, p. 11; 1957, p. 121, 193).<br />
